Layout transitions not working between pages

I have a number of pages (index.vue, login.vue and register.vue), as well as a layout auth.vue. I have a transition between login.vue and register.vue which works:

<script lang="ts" setup>
definePageMeta({
  layout: 'auth',

  layoutTransition: {
    name: 'slide-right',
    mode: 'out-in'
  },

  pageTransition: {
    name: 'slide-right',
    mode: 'out-in'
  }
})
</script>

<template>
  <div>
    <Login/>
  </div>
</template>

<style scoped>
.slide-right-enter-active {
  transition: all 0.6s;
}
.slide-right-enter-from,
.slide-right-leave-to {
  transform: translateX(-150%);
  opacity: 0;
}

.slide-right-leave-active {
  transition: all 0.6s;
}
</style>

<script lang="ts" setup>
definePageMeta({
  layout: 'auth',

  layoutTransition: {
    name: 'slide-right',
    mode: 'out-in'
  },

  pageTransition: {
    name: 'slide-right',
    mode: 'out-in'
  }
})
</script>

<template>
  <div>
    <Login/>
  </div>
</template>

<style scoped>
.slide-right-enter-active {
  transition: all 0.6s;
}
.slide-right-enter-from,
.slide-right-leave-to {
  transform: translateX(-150%);
  opacity: 0;
}

.slide-right-leave-active {
  transition: all 0.6s;
}
</style>

and

<script lang="ts" setup>
definePageMeta({
  layout: 'auth',

  layoutTransition: {
    name: 'slide-right',
    mode: 'out-in'
  },
  
  pageTransition: {
    name: 'slide-right',
    mode: 'out-in'
  }
})
</script>

<template>
  <div>
    <SignUp />
  </div>
</template>

<style scoped>
.slide-right-enter-active {
  transition: all 0.6s;
}
.slide-right-enter-from,
.slide-right-leave-to {
  transform: translateX(-150%);
  opacity: 0;
}

.slide-right-leave-active {
  transition: all 0.6s;
}
</style>

<script lang="ts" setup>
definePageMeta({
  layout: 'auth',

  layoutTransition: {
    name: 'slide-right',
    mode: 'out-in'
  },
  
  pageTransition: {
    name: 'slide-right',
    mode: 'out-in'
  }
})
</script>

<template>
  <div>
    <SignUp />
  </div>
</template>

<style scoped>
.slide-right-enter-active {
  transition: all 0.6s;
}
.slide-right-enter-from,
.slide-right-leave-to {
  transform: translateX(-150%);
  opacity: 0;
}

.slide-right-leave-active {
  transition: all 0.6s;
}
</style>

I'm trying to implement a similar transition between index.vue and either register.vue or login.vue. However, it doesn't seem to be working:

<script setup lang="ts">
definePageMeta({

  layoutTransition: {
    name: 'slide-left',
    mode: 'out-in'
  },

  pageTransition: {
    name: 'slide-left',
    mode: 'out-in'
  }
})
</script>

<style>
.slide-left-enter-active,
.slide-left-leave-active {
  transition: all 0.3s ease-in-out;
}

.slide-left-enter-from,
.slide-left-leave-to {
  transform: translateX(-100%);
}
</style>

<script setup lang="ts">
definePageMeta({

  layoutTransition: {
    name: 'slide-left',
    mode: 'out-in'
  },

  pageTransition: {
    name: 'slide-left',
    mode: 'out-in'
  }
})
</script>

<style>
.slide-left-enter-active,
.slide-left-leave-active {
  transition: all 0.3s ease-in-out;
}

.slide-left-enter-from,
.slide-left-leave-to {
  transform: translateX(-100%);
}
</style>

Why is this? I thought I needed a layout transition since index.vue uses the default layout, and login.vue and register.vue use the auth layout.

Hi @Viridian. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- I understand you're having issues with layout transitions between your index page and the login/register pages. This is a common issue when transitioning between pages with different layouts in Nuxt. Why Your Layout Transitions Aren't Working The main reason your transitions aren't working between the index page and login/register pages is that when you change layouts, the page transition you set doesn't run. Instead, you need to properly configure the layout transition. There are a few specific issues that could be causing your problem: 1. Layout Transitions vs Page Transitions: When changing layouts, the page transition is ignored in favor of the layout transition. Since you're moving between the default layout and the auth layout, the layout transition takes precedence. 2. Blank Screen Issue: There's a known issue in Nuxt where layout transitions can cause a blank screen to appear momentarily during navigation between different layouts, which might be disrupting your transition effect. 3. Transition Configuration: Your transition CSS might need to be placed in a global scope rather than scoped to individual components. Solutions Here are some approaches to fix your issue: 1. Move Transition CSS to app.vue Place your transition CSS in app.vue to ensure it's globally available:

<template>
  <NuxtLayout>
    <NuxtPage />
  </NuxtLayout>
</template>

<style>
.slide-left-enter-active,
.slide-left-leave-active,
.slide-right-enter-active,
.slide-right-leave-active {
  transition: all 0.4s;
}
.slide-left-enter-from,
.slide-left-leave-to {
  transform: translateX(-100%);
}
.slide-right-enter-from,
.slide-right-leave-to {
  transform: translateX(-150%);
  opacity: 0;
}
</style>

<template>
  <NuxtLayout>
    <NuxtPage />
  </NuxtLayout>
</template>

<style>
.slide-left-enter-active,
.slide-left-leave-active,
.slide-right-enter-active,
.slide-right-leave-active {
  transition: all 0.4s;
}
.slide-left-enter-from,
.slide-left-leave-to {
  transform: translateX(-100%);
}
.slide-right-enter-from,
.slide-right-leave-to {
  transform: translateX(-150%);
  opacity: 0;
}
</style>

2. Configure Global Transitions in nuxt.config.ts Set up global layout transitions in your Nuxt config:

export default defineNuxtConfig({
  app: {
    layoutTransition: {
      name: 'layout',
      mode: 'out-in'
    },
    pageTransition: {
      name: 'page',
      mode: 'out-in'
    }
  }
})

export default defineNuxtConfig({
  app: {
    layoutTransition: {
      name: 'layout',
      mode: 'out-in'
    },
    pageTransition: {
      name: 'page',
      mode: 'out-in'
    }
  }
})

3. Try Wrapping NuxtLayout in a div A known workaround for layout transition issues is to wrap your <NuxtLayout> in a div in your app.vue:

<template>
  <div>
    <NuxtLayout>
      <NuxtPage />
    </NuxtLayout>
  </div>
</template>

<template>
  <div>
    <NuxtLayout>
      <NuxtPage />
    </NuxtLayout>
  </div>
</template>

This solution has been reported to fix transition issues in some cases, as mentioned in a GitHub issue discussion. 4. Create a Blank Layout Instead of transitioning directly between different layouts, you could create a blank layout that just contains a <slot /> and use that for pages that need to transition between different layouts:

<!-- layouts/blank.vue -->
<template>
  <div>
    <slot />
  </div>
</template>

<!-- layouts/blank.vue -->
<template>
  <div>
    <slot />
  </div>
</template>

Then use this layout for transitioning pages:

definePageMeta({
  layout: "blank",
  // transitions here
})

definePageMeta({
  layout: "blank",
  // transitions here
})

This approach was suggested as a solution in a Stack Overflow post about similar transition issues. Recent Fixes It's worth noting that there have been recent fixes to layout transition issues in Nuxt. According to a GitHub issue, layout transitions previously had problems with scroll position and visibility during transitions, which might be related to your issue. These were fixed in a recent pull request. If you're using an older version of Nuxt, consider updating to the latest version to benefit from these fixes. I hope one of these solutions helps resolve your layout transition issues! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

ViridianOP•5mo ago

I moved all of the transitions to app.vue. Now the transition works from / to /login, but only once - after the first transition, going back from /login to / does nothing, and then / to login doesn't do anything anymore either. @kapa.ai

kapa.ai•5mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand you're experiencing an issue where your transitions only work for the first navigation but stop working afterward. This is a known issue with transitions in Nuxt when navigating between pages with different layouts. Why Transitions Stop Working After First Navigation The issue you're experiencing is likely related to how Nuxt handles transitions between different layouts. When you navigate from / to /login the first time, the transition works, but subsequent navigations fail because of how the transition state is being managed. Solutions to Fix One-Time Transition Issue Here are some approaches to fix this issue: 1. Wrap NuxtLayout in an Empty Div A simple solution that has worked for many users is to wrap your <NuxtLayout> component in an empty div in your app.vue:

<template>
  <div>
    <NuxtLayout>
      <NuxtPage />
    </NuxtLayout>
  </div>
</template>

<template>
  <div>
    <NuxtLayout>
      <NuxtPage />
    </NuxtLayout>
  </div>
</template>

This solution was confirmed to work in a GitHub issue discussion where a user had a similar problem. 2. Use a Blank Layout Instead of Disabling Layouts Instead of having some pages with a layout and others without, create a minimal "blank" layout that just renders the slot:

<!-- layouts/blank.vue -->
<template>
  <div>
    <slot />
  </div>
</template>

<!-- layouts/blank.vue -->
<template>
  <div>
    <slot />
  </div>
</template>

Then use this layout for your index page instead of having no layout:

definePageMeta({
  layout: "blank",
  layoutTransition: {
    name: 'slide-left',
    mode: 'out-in'
  }
})

definePageMeta({
  layout: "blank",
  layoutTransition: {
    name: 'slide-left',
    mode: 'out-in'
  }
})

This approach was suggested as a solution in a Stack Overflow post about transition issues between layouts. 3. Configure Both Page and Layout Transitions in nuxt.config.ts Make sure you have both page and layout transitions configured in your Nuxt config:

export default defineNuxtConfig({
  app: {
    pageTransition: {
      name: "page",
      mode: "out-in"
    },
    layoutTransition: {
      name: "layout",
      mode: "out-in"
    }
  }
})

export default defineNuxtConfig({
  app: {
    pageTransition: {
      name: "page",
      mode: "out-in"
    },
    layoutTransition: {
      name: "layout",
      mode: "out-in"
    }
  }
})

Then in your app.vue, define the CSS for both transitions:

<style>
.page-enter-active,
.page-leave-active,
.layout-enter-active,
.layout-leave-active {
  transition: all 0.4s;
}

.page-enter-from,
.page-leave-to {
  opacity: 0;
  transform: translateX(-100%);
}

.layout-enter-from,
.layout-leave-to {
  opacity: 0;
  transform: translateX(-100%);
}
</style>

<style>
.page-enter-active,
.page-leave-active,
.layout-enter-active,
.layout-leave-active {
  transition: all 0.4s;
}

.page-enter-from,
.page-leave-to {
  opacity: 0;
  transform: translateX(-100%);
}

.layout-enter-from,
.layout-leave-to {
  opacity: 0;
  transform: translateX(-100%);
}
</style>

This ensures that both page and layout transitions are properly defined and applied consistently. Try implementing these solutions one by one to see which one resolves your issue. The first solution (wrapping NuxtLayout in a div) is often the simplest and most effective for this particular problem. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

ViridianOP•5mo ago

This didn't fix it. Any recommendations? @kapa.ai I managed to get the transition to work more consistently by explicitly making a default.vue layout:

<script lang="ts" setup>

</script>

<template>
  <div>
    <p>default layout</p>
    <slot />
  </div>
</template>

<style scoped>

</style>

<script lang="ts" setup>

</script>

<template>
  <div>
    <p>default layout</p>
    <slot />
  </div>
</template>

<style scoped>

</style>

This makes the transition work from / --> /login - but trying to go back from login to / shows a blank page and nothing else. I already tried wrapping a div around NuxtLayout:

<template>
  <NuxtRouteAnnouncer />
  <NuxtLoadingIndicator />
  <UApp>
    <NuxtLayout>
      <NuxtPage class="font-site relative" />
    </NuxtLayout>
    <Version class="fixed bottom-4 left-4" />
  </UApp>
</template>

<style>
.slide-left-enter-active,
.slide-left-leave-active,
.slide-right-enter-active,
.slide-right-leave-active {
  transition: all 0.4s;
}

.slide-left-enter-from,
.slide-left-leave-to {
  transform: translateX(-100%);
}

.slide-right-enter-from,
.slide-right-leave-to {
  transform: translateX(-150%);
  opacity: 0;
}
</style>

<template>
  <NuxtRouteAnnouncer />
  <NuxtLoadingIndicator />
  <UApp>
    <NuxtLayout>
      <NuxtPage class="font-site relative" />
    </NuxtLayout>
    <Version class="fixed bottom-4 left-4" />
  </UApp>
</template>

<style>
.slide-left-enter-active,
.slide-left-leave-active,
.slide-right-enter-active,
.slide-right-leave-active {
  transition: all 0.4s;
}

.slide-left-enter-from,
.slide-left-leave-to {
  transform: translateX(-100%);
}

.slide-right-enter-from,
.slide-right-leave-to {
  transform: translateX(-150%);
  opacity: 0;
}
</style>

But that didn't work.

kapa.ai•5mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I see you're still having issues with transitions between layouts, particularly when navigating back from /login to / where you're seeing a blank page. This is a known issue with layout transitions in Nuxt. The Blank Page Issue The blank page you're experiencing when navigating back from /login to / is a documented issue with layout transitions in Nuxt. This happens because of how Nuxt handles the DOM during layout transitions. Looking at your code, I notice a few potential issues: 1. You've wrapped <NuxtLayout> in a <UApp> component rather than a simple <div>, which might be affecting the transition behavior. 2. Your default.vue layout has a <p>default layout</p> element that might be interfering with the transition. Solutions to Fix the Blank Page Issue Here are some approaches that should help resolve your issue: 1. Fix Your Layout Structure Make sure your layouts have a single root element that is not a <slot />. In your default.vue layout:

<template>
  <div>
    <slot />
  </div>
</template>

<template>
  <div>
    <slot />
  </div>
</template>

Remove the paragraph element as it might be causing issues with the transition. 2. Modify Your app.vue Try this structure in your app.vue:

<template>
  <div>
    <NuxtRouteAnnouncer />
    <NuxtLoadingIndicator />
    <NuxtLayout>
      <NuxtPage class="font-site relative" />
    </NuxtLayout>
    <Version class="fixed bottom-4 left-4" />
  </div>
</template>

<template>
  <div>
    <NuxtRouteAnnouncer />
    <NuxtLoadingIndicator />
    <NuxtLayout>
      <NuxtPage class="font-site relative" />
    </NuxtLayout>
    <Version class="fixed bottom-4 left-4" />
  </div>
</template>

Notice I've wrapped everything in a simple <div> and moved the <UApp> component. 3. Use setPageLayout for Dynamic Layout Changes Another approach is to use the setPageLayout utility to dynamically change layouts:

// In your navigation logic
function navigateToHome() {
  setPageLayout('default')
  navigateTo('/')
}

// In your navigation logic
function navigateToHome() {
  setPageLayout('default')
  navigateTo('/')
}

This method allows you to dynamically change the layout before navigation, which can help prevent the blank page issue. The setPageLayout function must be called before the layout is rendered by Vue to avoid hydration mismatches, as mentioned in the Nuxt documentation. 4. Check for Single Root Element in Pages Make sure all your pages have a single root element. According to the Nuxt documentation, pages must have a single root element to allow route transitions between pages:

<!-- Correct -->
<template>
  <div>
    <Login />
  </div>
</template>

<!-- Incorrect -->
<template>
  <div>First element</div>
  <div>Second element</div>
</template>

<!-- Correct -->
<template>
  <div>
    <Login />
  </div>
</template>

<!-- Incorrect -->
<template>
  <div>First element</div>
  <div>Second element</div>
</template>

5. Try Using a Blank Layout for Both Pages As suggested in a Stack Overflow post, create a blank layout that both pages can use:

<!-- layouts/blank.vue -->
<template>
  <div>
    <slot />
  </div>
</template>

<!-- layouts/blank.vue -->
<template>
  <div>
    <slot />
  </div>
</template>

Then use this layout for both your home page and login page:

definePageMeta({
  layout: "blank",
  // transitions here
})

definePageMeta({
  layout: "blank",
  // transitions here
})

This approach can help maintain consistent transitions between pages. 6. Configure Global Transitions in nuxt.config.ts Make sure you have both page and layout transitions properly configured:

export default defineNuxtConfig({
  app: {
    pageTransition: {
      name: "slide-left",
      mode: "out-in"
    },
    layoutTransition: {
      name: "slide-left",
      mode: "out-in"
    }
  }
})

export default defineNuxtConfig({
  app: {
    pageTransition: {
      name: "slide-left",
      mode: "out-in"
    },
    layoutTransition: {
      name: "slide-left",
      mode: "out-in"
    }
  }
})

Try these solutions one by one to see which resolves your blank page issue. The combination of a proper layout structure, single root elements in pages, and correctly configured transitions should help fix the problem. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

I fixed this by removing a comment in the top-level of my layout, as it counted as another node. @kapa.ai I have a WebSocket route routes/ws/chat/[id].ts. Is there a way to get the chat ID from the route parameters in the websocket handler? I cannot seem to access it through peer at all, and I want to make sure that clients can always connect to the right room ID, since my application will have multiple user-managed rooms (in a database too).

kapa.ai•5mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand you're trying to access route parameters in a WebSocket handler in Nuxt. This is a common need when implementing WebSocket functionality with dynamic routes. Accessing Route Parameters in WebSocket Handlers In Nuxt with Nitro (which powers Nuxt's server functionality), you can access route parameters in WebSocket handlers using the event context. WebSocket support was added in Nitro 2.9, and it allows you to access route parameters similar to how you would in regular API routes. Here's how you can access the chat ID from your WebSocket route:

// routes/ws/chat/[id].ts
import { defineWebSocketHandler } from 'h3'

export default defineWebSocketHandler({
  open(peer) {
    // Access the route parameter from the event context
    const chatId = peer.context.params.id
    
    console.log(`Client connected to chat room: ${chatId}`)
    
    // You can use the chatId to manage room subscriptions
    peer.subscribe(`chat:${chatId}`)
    peer.send({ message: `Welcome to chat room ${chatId}!` })
  },
  message(peer, message) {
    const chatId = peer.context.params.id
    
    // Process the message and broadcast to the specific room
    const msg = {
      room: chatId,
      text: message.toString(),
      sender: peer.toString()
    }
    
    // Publish to the specific chat room
    peer.publish(`chat:${chatId}`, msg)
  },
  close(peer) {
    const chatId = peer.context.params.id
    console.log(`Client disconnected from chat room: ${chatId}`)
  }
})

// routes/ws/chat/[id].ts
import { defineWebSocketHandler } from 'h3'

export default defineWebSocketHandler({
  open(peer) {
    // Access the route parameter from the event context
    const chatId = peer.context.params.id
    
    console.log(`Client connected to chat room: ${chatId}`)
    
    // You can use the chatId to manage room subscriptions
    peer.subscribe(`chat:${chatId}`)
    peer.send({ message: `Welcome to chat room ${chatId}!` })
  },
  message(peer, message) {
    const chatId = peer.context.params.id
    
    // Process the message and broadcast to the specific room
    const msg = {
      room: chatId,
      text: message.toString(),
      sender: peer.toString()
    }
    
    // Publish to the specific chat room
    peer.publish(`chat:${chatId}`, msg)
  },
  close(peer) {
    const chatId = peer.context.params.id
    console.log(`Client disconnected from chat room: ${chatId}`)
  }
})

The route parameters are accessible through peer.context.params, similar to how you would access them in regular API routes with event.context.params. Additional WebSocket Considerations When working with WebSockets in Nuxt/Nitro, keep these points in mind: 1. Room Management: As shown in the example, you can use the peer.subscribe() method to subscribe clients to specific rooms based on the chat ID. 2. Client Implementation: On the client side, you'll need to connect to the correct WebSocket URL including the chat ID:

const chatId = '123'
const socket = new WebSocket(`ws://${window.location.host}/ws/chat/${chatId}`)

const chatId = '123'
const socket = new WebSocket(`ws://${window.location.host}/ws/chat/${chatId}`)

3. Database Integration: Since you mentioned storing rooms in a database, you can use the chat ID to query your database and validate if the room exists before allowing the connection. 4. Error Handling: Consider implementing error handling to manage cases where a client tries to connect to a non-existent room. For more information on WebSocket implementation in Nitro, you can refer to the H3 WebSocket documentation. This approach should allow you to properly manage multiple chat rooms with unique IDs in your Nuxt application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai When I log peer.context I get {}. Here's my chat.vue page:

<script lang="ts" setup>
const { open, send } = useWebSocket('/ws/chat/123', {
  immediate: false,
  async onMessage(ws, event) {
    console.log(event.data);
  }
})

onMounted(() => {
  open();
})
</script>

<template>
  <div>
    Chat
  </div>
  <UButton @click="send('test')">Send some data</UButton> 
</template>

<style scoped>

</style>

<script lang="ts" setup>
const { open, send } = useWebSocket('/ws/chat/123', {
  immediate: false,
  async onMessage(ws, event) {
    console.log(event.data);
  }
})

onMounted(() => {
  open();
})
</script>

<template>
  <div>
    Chat
  </div>
  <UButton @click="send('test')">Send some data</UButton> 
</template>

<style scoped>

</style>

What do I change to give the context to the peer?

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand you're having trouble accessing route parameters in your WebSocket handler. This is a common issue when working with WebSockets in Nuxt/Nitro. Accessing Route Parameters in WebSocket Handlers When you're using WebSockets in Nuxt with Nitro, the route parameters should be accessible through the event context, but there are some specific requirements to make this work correctly. Based on your code and the empty peer.context you're seeing, here's how to fix it: 1. Correct WebSocket Handler Structure Your WebSocket handler should be defined using the proper structure to access route parameters:

// server/ws/chat/[id].ts (not routes/ws/chat/[id].ts)
import { defineWebSocketHandler } from 'h3'

export default defineWebSocketHandler({
  open(peer) {
    // Log the entire peer object to see what's available
    console.log('Peer connected:', peer.context.params);
    
    const id = getRouterParam(peer, 'id');
    console.log(`Client connected to chat room: ${id}`);
    
    peer.send(JSON.stringify({ message: `Welcome to chat room ${id}!` }));
  },
  message(peer, message) {
    const id = getRouterParam(peer, 'id');
    console.log(`Message in room ${id}:`, message.toString());
    
    // Process and broadcast message
    peer.send(JSON.stringify({ 
      room: id,
      text: message.toString(),
      received: true
    }));
  },
  close(peer) {
    const id = getRouterParam(peer, 'id');
    console.log(`Client disconnected from chat room: ${id}`);
  }
})

// server/ws/chat/[id].ts (not routes/ws/chat/[id].ts)
import { defineWebSocketHandler } from 'h3'

export default defineWebSocketHandler({
  open(peer) {
    // Log the entire peer object to see what's available
    console.log('Peer connected:', peer.context.params);
    
    const id = getRouterParam(peer, 'id');
    console.log(`Client connected to chat room: ${id}`);
    
    peer.send(JSON.stringify({ message: `Welcome to chat room ${id}!` }));
  },
  message(peer, message) {
    const id = getRouterParam(peer, 'id');
    console.log(`Message in room ${id}:`, message.toString());
    
    // Process and broadcast message
    peer.send(JSON.stringify({ 
      room: id,
      text: message.toString(),
      received: true
    }));
  },
  close(peer) {
    const id = getRouterParam(peer, 'id');
    console.log(`Client disconnected from chat room: ${id}`);
  }
})

2. File Location and Naming Make sure your WebSocket handler is in the correct location: - It should be in the server/ directory, not routes/ - The correct path would be server/ws/chat/[id].ts 3. Using getRouterParam As shown in the Nuxt server documentation, you should use the getRouterParam helper function to access route parameters:

const id = getRouterParam(peer, 'id');

const id = getRouterParam(peer, 'id');

This is the recommended way to access route parameters in Nitro server handlers. 4. Client-Side Connection Your client-side code looks good, but make sure you're connecting to the correct WebSocket URL:

const { open, send } = useWebSocket('/ws/chat/123', {
  immediate: false,
  async onMessage(ws, event) {
    console.log(event.data);
  }
})

const { open, send } = useWebSocket('/ws/chat/123', {
  immediate: false,
  async onMessage(ws, event) {
    console.log(event.data);
  }
})

5. Nitro Version Check Make sure you're using Nitro 2.9 or later, as WebSocket support was added in that version. You can check this in your package.json dependencies. If you're using the latest version of Nuxt, you should have access to this functionality as mentioned in the YouTube video about WebSockets in Nuxt and Nitro. Additional Troubleshooting If you're still having issues after implementing these changes: 1. Try logging the entire peer object to see what properties are available 2. Make sure your WebSocket route is correctly registered by checking the Nuxt server logs during startup 3. Verify that your client is connecting to the correct URL by checking browser network requests By implementing these changes, you should be able to access the route parameters in your WebSocket handler and manage your chat rooms effectively. Let me know if you need any further clarification! YouTube [Nuxt 3]: Integrating WebSockets in Nuxt and Nitro provides a comprehensive guide on setting up WebSockets in Nuxt and Nitro that might be helpful for your implementation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I have this socket code:

import { useNuxtApp } from 'nuxt/app';

export default defineWebSocketHandler({

  open(peer) {
    console.log('Peer connected!: ', peer.id);

    const chatId = `chat:${peer.request.url.split('/')[5]}`;
    
    peer.subscribe(chatId);

    console.log(`Peer ${peer.id} subscribed to chat: ${chatId}`); 
  },

  message(peer, message) {
    console.log(`chat:${peer.request.url.split('/')[5]}`);
    console.log('Message received: ', message.data instanceof Buffer ? message.data.toString() : message.data);
    peer.publish(`chat:${peer.request.url.split('/')[5]}`, message.data);
  },

  close(peer) {
    console.log('Peer disconnected: ', peer.id);
    peer.unsubscribe(`chat:${peer.request.url.split('/')[5]}`);
    console.log(`Peer ${peer.id} unsubscribed from chat:${peer.request.url.split('/')[5]}`);
  },
})

import { useNuxtApp } from 'nuxt/app';

export default defineWebSocketHandler({

  open(peer) {
    console.log('Peer connected!: ', peer.id);

    const chatId = `chat:${peer.request.url.split('/')[5]}`;
    
    peer.subscribe(chatId);

    console.log(`Peer ${peer.id} subscribed to chat: ${chatId}`); 
  },

  message(peer, message) {
    console.log(`chat:${peer.request.url.split('/')[5]}`);
    console.log('Message received: ', message.data instanceof Buffer ? message.data.toString() : message.data);
    peer.publish(`chat:${peer.request.url.split('/')[5]}`, message.data);
  },

For some reason, the code in the onMessage function doesn't run whenever a message is published. What am I doing wrong?

kapa.ai•5mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I can see you're having an issue with your WebSocket implementation in Nuxt where the onMessage function isn't being triggered when messages are published. Let's analyze what might be going wrong. Possible Issues with Your WebSocket Implementation Looking at your code, I've identified a few potential issues: 1. Message Format Mismatch In your server-side code, you're publishing the message data directly:

peer.publish(`chat:${peer.request.url.split('/')[5]}`, message.data);

peer.publish(`chat:${peer.request.url.split('/')[5]}`, message.data);

But in your client-side code, you're expecting to parse JSON:

const newMessage = JSON.parse(event.data) as Message;

const newMessage = JSON.parse(event.data) as Message;

If message.data is already a string representation of JSON, this should work. However, if it's already a JavaScript object or in another format, this could cause issues. 2. WebSocket Connection Issues Make sure your WebSocket connection is actually open before trying to receive messages. You're setting immediate: false and then calling open() in onMounted, which is correct, but you might want to add some logging to verify the connection is established:

const { open, send, status } = useWebSocket(`/ws/chat/${route.params.id}`, {
  immediate: false,
  onOpen() {
    console.log('WebSocket connection opened');
  },
  onError(ws, event) {
    console.error('WebSocket error:', event);
  },
  async onMessage(ws, event) {
    console.log('Raw message received:', event.data);
    try {
      const newMessage = JSON.parse(event.data) as Message;
      messages.value.push(newMessage);
      scrollToBottom();
    } catch (error) {
      console.error('Error parsing message:', error);
    }
  }
});

const { open, send, status } = useWebSocket(`/ws/chat/${route.params.id}`, {
  immediate: false,
  onOpen() {
    console.log('WebSocket connection opened');
  },
  onError(ws, event) {
    console.error('WebSocket error:', event);
  },
  async onMessage(ws, event) {
    console.log('Raw message received:', event.data);
    try {
      const newMessage = JSON.parse(event.data) as Message;
      messages.value.push(newMessage);
      scrollToBottom();
    } catch (error) {
      console.error('Error parsing message:', error);
    }
  }
});

3. Subscription Issues In your server code, you're subscribing the peer to a channel:

const chatId = `chat:${peer.request.url.split('/')[5]}`;
peer.subscribe(chatId);

const chatId = `chat:${peer.request.url.split('/')[5]}`;
peer.subscribe(chatId);

Make sure this channel name exactly matches the one you're publishing to:

peer.publish(`chat:${peer.request.url.split('/')[5]}`, message.data);

peer.publish(`chat:${peer.request.url.split('/')[5]}`, message.data);

The URL parsing could be inconsistent. Consider logging both values to ensure they match. 4. Message Format in send() vs publish() When you send a message from the client, you're doing:

send(JSON.stringify(response));

send(JSON.stringify(response));

But on the server, you're publishing the raw message data:

peer.publish(`chat:${peer.request.url.split('/')[5]}`, message.data);

peer.publish(`chat:${peer.request.url.split('/')[5]}`, message.data);

Try modifying your server code to ensure consistent formatting:

message(peer, message) {
  const chatId = `chat:${peer.request.url.split('/')[5]}`;
  console.log(`Publishing to ${chatId}`);
  
  // Make sure we're working with string data
  const messageData = message.data instanceof Buffer 
    ? message.data.toString() 
    : message.data;
  
  console.log('Message to publish:', messageData);
  
  // Publish the message to all subscribers of this chat
  peer.publish(chatId, messageData);
}

message(peer, message) {
  const chatId = `chat:${peer.request.url.split('/')[5]}`;
  console.log(`Publishing to ${chatId}`);
  
  // Make sure we're working with string data
  const messageData = message.data instanceof Buffer 
    ? message.data.toString() 
    : message.data;
  
  console.log('Message to publish:', messageData);
  
  // Publish the message to all subscribers of this chat
  peer.publish(chatId, messageData);
}

Debugging Recommendations 1. Add more logging on both client and server sides to track the flow of messages 2. Verify that the WebSocket connection is successfully established 3. Check that the channel names for subscribe and publish match exactly 4. Ensure the message format is consistent between client and server Based on the YouTube video about WebSockets in Nuxt and Nitro, make sure you're following the recommended patterns for WebSocket implementation in Nuxt. If you're still having issues after these changes, you might want to try a simpler implementation first to verify the basic functionality works, then gradually add complexity back in.

I get this error after migrating to NuxtUI v3: runtime-core.esm-bundler.js:51:13 Uncaught (in promise) Error: Columns require an id when using a non-string header How can I fix this?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The error you're seeing:

Uncaught (in promise) Error: Columns require an id when using a non-string header

Uncaught (in promise) Error: Columns require an id when using a non-string header

is due to a change in how columns are defined in Nuxt UI v3. In Nuxt UI v3, the table component is built on top of TanStack Table, and the column definitions have changed. Specifically, when you use a non-string header (such as a function or a slot), you must provide an explicit id for the column. Also, the column property names have changed from key/label to accessorKey/header (and optionally id). Here's how you can update your columns for Nuxt UI v3:

const drColumns = [
  { accessorKey: 'email', header: 'Email', id: 'email', meta: { class: { td: 'w-24' } } },
  { accessorKey: 'requested', header: 'Delete request on', id: 'requested', meta: { class: { td: 'w-24' } } },
  { accessorKey: 'approved', header: 'Approved on', id: 'approved', meta: { class: { td: 'w-24' } } },
  { accessorKey: 'id', header: 'Action', id: 'id', meta: { class: { td: 'w-20' } } }
]

const drColumns = [
  { accessorKey: 'email', header: 'Email', id: 'email', meta: { class: { td: 'w-24' } } },
  { accessorKey: 'requested', header: 'Delete request on', id: 'requested', meta: { class: { td: 'w-24' } } },
  { accessorKey: 'approved', header: 'Approved on', id: 'approved', meta: { class: { td: 'w-24' } } },
  { accessorKey: 'id', header: 'Action', id: 'id', meta: { class: { td: 'w-20' } } }
]

- Use accessorKey instead of key. - Use header instead of label. - Add an explicit id for each column. - For classes, use the meta property as shown in the Nuxt UI Table documentation. Also, in Nuxt UI v3, you should use the new slot syntax for customizing cells, for example:

<UTable :columns="drColumns" :data="drList" :loading="loading">
  <template #requested-cell="{ row }">
    <div class="w-24">
      {{ row.requested ? new Date(row.requested.seconds*1000).toLocaleString() : 'unknown' }}
    </div>
  </template>
  <template #approved-cell="{ row }">
    <div class="w-24">
      {{ row.approved ? new Date(row.approved.seconds*1000).toLocaleString() : '' }}
    </div>
  </template>
  <template #id-cell="{ row }">
    <div class="w-20">
      <UButton v-if="!row.approved" label="Approve" @click="clkApprove(row.id)" />
      <span v-else>Approved</span>
    </div>
  </template>
</UTable>

<UTable :columns="drColumns" :data="drList" :loading="loading">
  <template #requested-cell="{ row }">
    <div class="w-24">
      {{ row.requested ? new Date(row.requested.seconds*1000).toLocaleString() : 'unknown' }}
    </div>
  </template>
  <template #approved-cell="{ row }">
    <div class="w-24">
      {{ row.approved ? new Date(row.approved.seconds*1000).toLocaleString() : '' }}
    </div>
  </template>
  <template #id-cell="{ row }">
    <div class="w-20">
      <UButton v-if="!row.approved" label="Approve" @click="clkApprove(row.id)" />
      <span v-else>Approved</span>
    </div>
  </template>
</UTable>

Note the slot names are now #<column-id>-cell instead of #<column-id>-data see documentation. Summary:
- Update your columns to use accessorKey, header, and an explicit id. - Use the new slot naming convention for cell customization. For more details, see the Nuxt UI Table columns documentation and slot customization. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Can you show me how I can make the width of a UModal larger by default? It's holding a table with a lot of columns

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To make a UModal larger by default, you can customize its width using the modal slot's class. If you are using a component like UModal from Nuxt UI Pro, you can apply a class to the modal slot to control its maximum width. For example, you can use Tailwind CSS classes such as max-w-3xl, max-w-4xl, or a custom width. You can set this globally for components like DashboardSearch or ContentSearch by configuring the modal slot in your app.config.ts:

export default defineAppConfig({
  uiPro: {
    dashboardSearch: {
      slots: {
        modal: 'sm:max-w-3xl sm:h-[28rem]', // adjust max-w-3xl to your desired width
      }
    }
  }
})

export default defineAppConfig({
  uiPro: {
    dashboardSearch: {
      slots: {
        modal: 'sm:max-w-3xl sm:h-[28rem]', // adjust max-w-3xl to your desired width
      }
    }
  }
})

Or for ContentSearch:

export default defineAppConfig({
  uiPro: {
    contentSearch: {
      slots: {
        modal: 'sm:max-w-3xl sm:h-[28rem]', // adjust as needed
      }
    }
  }
})

export default defineAppConfig({
  uiPro: {
    contentSearch: {
      slots: {
        modal: 'sm:max-w-3xl sm:h-[28rem]', // adjust as needed
      }
    }
  }
})

You can use a similar approach for your own modal by applying a class to the modal container to increase its width, for example:

<UModal>
  <template #content>
    <div class="max-w-4xl w-full">
      <!-- Your table here -->
    </div>
  </template>
</UModal>

<UModal>
  <template #content>
    <div class="max-w-4xl w-full">
      <!-- Your table here -->
    </div>
  </template>
</UModal>

Replace max-w-4xl with the width that fits your table best.

@kapa.ai How can I pass reactive props to a modal that I am opening programatically? For example, I have this code for my modal:

<template>
  <UModal :ui="{ width: 'md:max-w-4xl' }" title="Processing Log">
    <div class="p-4">
      <pre class="bg-gray-100 dark:bg-gray-800 p-4 rounded-lg text-sm overflow-auto max-h-96">{{ props.progressModalText }}
    </pre>
    </div>
  </UModal>
</template>

<script lang="ts" setup>

const props = defineProps<{
  progressModalText: Ref<string>;
}>();

</script>

<style></style>

<template>
  <UModal :ui="{ width: 'md:max-w-4xl' }" title="Processing Log">
    <div class="p-4">
      <pre class="bg-gray-100 dark:bg-gray-800 p-4 rounded-lg text-sm overflow-auto max-h-96">{{ props.progressModalText }}
    </pre>
    </div>
  </UModal>
</template>

<script lang="ts" setup>

const props = defineProps<{
  progressModalText: Ref<string>;
}>();

</script>

<style></style>

And this code in another file:

const progressModalText = ref('')

const addProgress = (msg: string) => {
  progressModalText.value = progressModalText.value + '\n' + msg
}

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText: progressModalText
  }
})

const progressModalText = ref('')

const addProgress = (msg: string) => {
  progressModalText.value = progressModalText.value + '\n' + msg
}

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText: progressModalText
  }
})

But the modal doesn't update with the new text whenever the ref is updated.

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To pass reactive props to a modal opened programmatically with Nuxt UI's useOverlay, you need to ensure that the prop you pass is a ref and that the modal component is set up to accept a ref as a prop. However, the reactivity will only be preserved if you pass the ref itself, not its value. From your example, you are already passing a ref (progressModalText) as a prop:

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText: progressModalText
  }
})

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText: progressModalText
  }
})

And your modal component is set up to accept a Ref<string>:

const props = defineProps<{
  progressModalText: Ref<string>;
}>();

const props = defineProps<{
  progressModalText: Ref<string>;
}>();

This is the correct approach.
However, if you find that the modal does not update when the ref changes, it may be due to how the overlay system handles prop updates. According to the Nuxt UI documentation, if you want to update the props of an already opened overlay, you should use the patch method on the overlay instance:

modal.patch({
  progressModalText: progressModalText
})

modal.patch({
  progressModalText: progressModalText
})

This will update the props of the modal with the latest ref, ensuring reactivity is maintained.
If you want the modal to always reflect the latest value, make sure you are not accidentally passing the value (progressModalText.value) instead of the ref itself. Summary of steps: 1. Pass the ref itself as a prop when creating or opening the modal. 2. If you need to update the prop after the modal is open, use modal.patch({ ... }) to update the prop on the fly. For more on updating overlay props, see the Nuxt UI useOverlay composable documentation. If you follow this pattern and still do not see updates, it may be a limitation or bug in the current overlay implementation, as the documentation does not explicitly guarantee deep reactivity for refs passed as props to overlays. In that case, you may need to close and reopen the modal or use a global store for the shared state. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai How can you listen to emitted events from programatically created modals? For example, when one of them is closed, I would like to clear some values

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To listen to emitted events (such as close) from programmatically created modals using Nuxt UI's useOverlay, you should attach event listeners when you open the modal. The open() method returns an instance with a result promise that resolves when the modal emits a close event. You can use this to perform actions (like clearing values) when the modal is closed. Example:

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText: progressModalText
  }
})

async function openModal() {
  const instance = modal.open()
  await instance.result // This resolves when the modal emits 'close'
  // Clear your values here
  progressModalText.value = ''
}

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText: progressModalText
  }
})

async function openModal() {
  const instance = modal.open()
  await instance.result // This resolves when the modal emits 'close'
  // Clear your values here
  progressModalText.value = ''
}

This pattern is described in the Nuxt UI migration guide and overlay composable documentation:

Overlays that are opened, can be awaited for their result. Overlays can no longer be closed using modal.close(), rather, they close automatically: either when a close event is fired explicitly from the opened component OR when the overlay closes itself (clicking on backdrop, pressing the ESC key, etc). To capture the return value in the parent component you must explicitly emit a close event with the desired value

Getting-started > Changes from v2 So, awaiting instance.result is the recommended way to react to modal events like close when using programmatic overlays in Nuxt UI. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai This pattern doesn't work because the modal needs to update text while it is open. Here is my current code:

const progressModalText = ref('')

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText: progressModalText.value
  }
})

const addProgress = (msg: string) => {
  progressModalText.value = progressModalText.value + '\n' + msg

  modal.patch({
    progressModalText: progressModalText.value
  })
}

const progressModalText = ref('')

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText: progressModalText.value
  }
})

const addProgress = (msg: string) => {
  progressModalText.value = progressModalText.value + '\n' + msg

  modal.patch({
    progressModalText: progressModalText.value
  })
}

Making it await a close event will not update the text within my modal, as I call addProgress in a separate function that is run on opening the modal. How can I work around this?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the knowledge sources, the recommended way to keep a programmatically opened modal in sync with reactive data is to pass the ref itself as a prop, not its value. This way, the modal will reactively update as the ref changes, and you do not need to call patch every time the value changes. Here's how you should set it up: 1. Pass the ref, not its value, when creating the modal:

const progressModalText = ref('')

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText // pass the ref itself, not progressModalText.value
  }
})

const progressModalText = ref('')

const modal = overlay.create(ProcessingModal, {
  props: {
    progressModalText // pass the ref itself, not progressModalText.value
  }
})

2. In your modal component, accept the prop as a Ref:

const props = defineProps<{
  progressModalText: Ref<string>
}>()

const props = defineProps<{
  progressModalText: Ref<string>
}>()

3. Now, whenever you update progressModalText.value, the modal will update automatically:

const addProgress = (msg: string) => {
  progressModalText.value = progressModalText.value + '\n' + msg
}

const addProgress = (msg: string) => {
  progressModalText.value = progressModalText.value + '\n' + msg
}

You do not need to call modal.patch for every update—the reactivity will be preserved as long as you pass the ref itself. This approach is supported by the Nuxt UI documentation, which shows that passing a ref as a prop allows the overlay to stay in sync with the reactive value (see Provide/Inject caveat). If you pass progressModalText.value, you are passing a static value, and the modal will not update when the ref changes. Passing the ref itself ensures reactivity. --- Summary:
- Pass the ref, not its value, as a prop to the modal. - The modal will update reactively as the ref changes. - No need to call patch for every update. If you follow this pattern and still do not see updates, the knowledge sources do not provide further troubleshooting steps, and it may be a limitation or bug in the current overlay implementation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I can use :close and use onClick to determine the behavior when the user closes by pressing the close button, but how can I set behavior for when the user dismisses it by clicking off of the modal or pressing escape?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The knowledge sources do not explicitly mention a dedicated event or prop for handling dismissal of a UModal via clicking outside or pressing escape. However, they do state that you can control whether the modal is dismissible using the dismissible prop (:dismissible="false" to prevent closing by outside click or escape) and that a close:prevent event is emitted when dismissal is attempted but prevented this way UModal Control Open State. If you need to react to the modal being closed by any means (including outside click or escape), the recommended approach is to listen for the close event, as this is emitted whenever the modal is closed—regardless of the method. If you specifically want to detect when a dismissal is attempted but prevented, you can listen for the close:prevent event. Example:

<UModal
  @close="onModalClose"
  @close:prevent="onModalDismissPrevented"
  :dismissible="true"
>
  <!-- modal content -->
</UModal>

<UModal
  @close="onModalClose"
  @close:prevent="onModalDismissPrevented"
  :dismissible="true"
>
  <!-- modal content -->
</UModal>

- Use @close to handle all close events (including outside click, escape, and close button). - Use @close:prevent to handle cases where dismissal is attempted but prevented by :dismissible="false". For more details, see the UModal documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Do UTables have a way to sort columns by default without having to define your own icons, for example? I want there to be an icon for each header where sorting is possible.

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Yes, UTable in Nuxt UI provides built-in support for sortable columns, and it will automatically display a sorting icon in the header for columns where sorting is enabled. You do not need to define your own icons for this basic functionality. By default, if you set enableSorting: true (which is the default for most columns), UTable will show a sorting icon in the header. The icon updates to reflect the current sort direction (ascending, descending, or unsorted). You only need to define your columns and enable sorting as needed:

const columns = [
  { accessorKey: 'email', header: 'Email', enableSorting: true },
  { accessorKey: 'date', header: 'Date', enableSorting: true },
  // ...
]

const columns = [
  { accessorKey: 'email', header: 'Email', enableSorting: true },
  { accessorKey: 'date', header: 'Date', enableSorting: true },
  // ...
]

If you want to customize the sorting icon or header further, you can provide a custom header function, but for the default behavior, UTable handles the icons for you automatically. This is shown in the documentation and examples, where sorting icons appear by default on sortable columns without custom icon definitions Components > With row actions. So, you get sorting icons out of the box for sortable columns in UTable. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I want to create a wrapper component for UTable that handles the creation of headers with sort buttons. Can I pass templates with slots e.g. #actions-cell from the wrapper to the UTable inside?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The knowledge sources do not explicitly document a way to forward or pass named slots (such as #actions-cell) from a wrapper component to the inner UTable component. In the official Nuxt UI Table documentation, slots like #<column>-cell are used directly on the UTable component to customize cells and headers, but there is no mention of a pattern or API for forwarding these slots through a wrapper component Table with slots. Therefore, I'm sorry, but there's no information in the knowledge sources about passing or forwarding UTable's named slots from a wrapper component to the inner UTable. You may need to define your custom cell and header templates directly on the UTable instance, as shown in the documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you again. One moment! :books: ---------------------- When you apply the sticky prop to a UTable, it should make the table header sticky by default. According to the Nuxt UI documentation, the sticky prop is supported and, when set to true, applies the necessary classes to the table header to make it sticky:

<UTable sticky :data="data" class="flex-1 max-h-[312px]" />

<UTable sticky :data="data" class="flex-1 max-h-[312px]" />

This will apply a class like sticky top-0 inset-x-0 bg-default/75 z-[1] backdrop-blur to the <thead> element, as defined in the theme configuration for the table component Table Theme. If sticky is not working: - Make sure the table or its container has a fixed height and overflow-y: auto or overflow: auto. Sticky headers require a scrollable container to function. - Example from the docs:

  <UTable sticky :data="data" class="flex-1 max-h-[312px]" />

  <UTable sticky :data="data" class="flex-1 max-h-[312px]" />

Here, max-h-[312px] ensures the table has a scrollable area Table Loading Example. - If you are using a wrapper component, ensure that the wrapper or a parent element provides the necessary height and overflow styles. Summary:
- The sticky prop works out of the box if the table is inside a scrollable container with a set height. - If it’s not working, check your container’s CSS for height and overflow. If you have followed these requirements and it still does not work, the knowledge sources do not provide further troubleshooting steps. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Though I get this error when I added the v-model:sorting="sort" part: Uncaught (in promise) TypeError: _table$getState$sorti.find is not a function NuxtJS 72 What's causing this?

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The error

Uncaught (in promise) TypeError: _table$getState$sorti.find is not a function

Uncaught (in promise) TypeError: _table$getState$sorti.find is not a function

is caused by the format of the value you are passing to v-model:sorting. According to the Nuxt UI Table documentation, the sorting prop expects an array of sorting objects, not a single object. Correct format:

const sort = ref([
  { id: 'requested', desc: true }
])

const sort = ref([
  { id: 'requested', desc: true }
])

Incorrect format (what you currently have):

const sort = ref({
  id: 'requested',
  desc: true
})

const sort = ref({
  id: 'requested',
  desc: true
})

The error occurs because the table tries to call .find on the value you provide, which only works on arrays, not objects. How to fix:
Change your sort definition to an array:

const sort = ref([
  { id: 'requested', desc: true }
])

const sort = ref([
  { id: 'requested', desc: true }
])

This matches the expected input for the sorting prop as described in the UTable documentation:

const sorting = ref([ { id: 'id', desc: false } ])

This should resolve the error and allow sorting to work as expected. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai - How can I adjust the vertical padding of the table rows I am using? I have this so far:

<UTable v-bind="attrs" :columns="props.columns" :data="data" :sticky="true" :ui="{
    wrapper: 'relative',
    base: 'w-full',
    thead: 'sticky top-0 z-10',
    tbody: 'divide-y divide-gray-200 dark:divide-gray-700',
    tr: {
      base: 'hover:bg-gray-50 dark:hover:bg-gray-700/50 transition-colors'
    },
    td: {
      base: 'whitespace-nowrap',
      padding: 'px-4 py-3',
      font: 'text-sm',
      color: 'text-gray-900 dark:text-gray-100'
    },
    th: {
      base: 'whitespace-nowrap',
      padding: 'px-4 py-3',
      font: 'text-xs font-semibold uppercase tracking-wider',
      color: 'text-gray-700 dark:text-gray-300'
    }
  }">

<UTable v-bind="attrs" :columns="props.columns" :data="data" :sticky="true" :ui="{
    wrapper: 'relative',
    base: 'w-full',
    thead: 'sticky top-0 z-10',
    tbody: 'divide-y divide-gray-200 dark:divide-gray-700',
    tr: {
      base: 'hover:bg-gray-50 dark:hover:bg-gray-700/50 transition-colors'
    },
    td: {
      base: 'whitespace-nowrap',
      padding: 'px-4 py-3',
      font: 'text-sm',
      color: 'text-gray-900 dark:text-gray-100'
    },
    th: {
      base: 'whitespace-nowrap',
      padding: 'px-4 py-3',
      font: 'text-xs font-semibold uppercase tracking-wider',
      color: 'text-gray-700 dark:text-gray-300'
    }
  }">

But adjusting the 'padding' property doesn't seem to do anything.

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The knowledge sources indicate that you can adjust the vertical padding of table rows in UTable by customizing the td and th slots using the ui prop. The padding property you are using in your ui object is correct according to the documented theme structure for UTable:

td: {
  base: 'whitespace-nowrap',
  padding: 'px-4 py-3',
  font: 'text-sm',
  color: 'text-gray-900 dark:text-gray-100'
},
th: {
  base: 'whitespace-nowrap',
  padding: 'px-4 py-3',
  font: 'text-xs font-semibold uppercase tracking-wider',
  color: 'text-gray-700 dark:text-gray-300'
}

td: {
  base: 'whitespace-nowrap',
  padding: 'px-4 py-3',
  font: 'text-sm',
  color: 'text-gray-900 dark:text-gray-100'
},
th: {
  base: 'whitespace-nowrap',
  padding: 'px-4 py-3',
  font: 'text-xs font-semibold uppercase tracking-wider',
  color: 'text-gray-700 dark:text-gray-300'
}

However, the knowledge sources do not explicitly confirm whether the padding property is merged into the final class list or if only the base property is used for the slot classes. In the official UTable theme documentation, the slot classes are typically defined as a single string (e.g., td: 'px-4 py-3 ...'), not as separate base, padding, etc. To ensure your padding is applied, try combining all classes into the base property:

td: {
  base: 'whitespace-nowrap px-4 py-1 text-sm text-gray-900 dark:text-gray-100'
},
th: {
  base: 'whitespace-nowrap px-4 py-1 text-xs font-semibold uppercase tracking-wider text-gray-700 dark:text-gray-300'
}

td: {
  base: 'whitespace-nowrap px-4 py-1 text-sm text-gray-900 dark:text-gray-100'
},
th: {
  base: 'whitespace-nowrap px-4 py-1 text-xs font-semibold uppercase tracking-wider text-gray-700 dark:text-gray-300'
}

Adjust the py-1 (vertical padding) to your desired value. Summary:
- Combine your padding classes directly into the base property for td and th in the ui prop. - The padding property may not be recognized; use base for all classes as shown in the UTable theme example. If you follow this pattern, your vertical padding adjustments should take effect. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai How can I style a NuxtUI UTable <tr> based on its row data? For example, I want to change its background style if some data is a specific way. e.g.:

const data = context.row;
      const isBehind = data.isOutdated || data.energyDataCount === 0;

      if (isBehind) {
        if (data.periodsBehind > 2) {
          return 'bg-red-500 dark:bg-red-900/20'; // Critical
        }
        return 'bg-amber-50 dark:bg-amber-900/20'; // Behind or No Data
      }
      return ''; // Default

const data = context.row;
      const isBehind = data.isOutdated || data.energyDataCount === 0;

      if (isBehind) {
        if (data.periodsBehind > 2) {
          return 'bg-red-500 dark:bg-red-900/20'; // Critical
        }
        return 'bg-amber-50 dark:bg-amber-900/20'; // Behind or No Data
      }
      return ''; // Default

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The knowledge sources do not explicitly document a built-in way to style a <tr> in UTable based on its row data using a function or callback. However, the UTable documentation does mention the use of the meta property for columns, which allows you to add classes to td and th elements, but not directly to the <tr> element. There is a mention in the theme configuration for UTable of a tr slot and a tr.base class, which suggests you can globally style table rows, but not dynamically per row based on data using a function in the column definition or a prop. Therefore, I'm sorry, but the knowledge sources do not provide a documented way to style a <tr> in UTable based on its row data. You may be able to achieve this with a custom wrapper or by using a slot if such a feature is added in the future, but this is not covered in the current documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

For some reason, the SelectMenu does not show the currently selected value when uncollapsed. When opening the select menu it shows the correct selected value, but it doesn't show the value on the main select.

Let me check the knowledge base for you again. One moment! :books: ---------------------- I'm sorry, but the knowledge sources do not contain specific information about the option-attribute and value-attribute props for USelectMenu in NuxtUI v2, nor do they describe issues with the selected value not displaying in the collapsed state. The available documentation for USelectMenu in Nuxt UI (v3) describes using items, labelKey, and valueKey for mapping options and values, but does not mention option-attribute or value-attribute props or their behavior in v2. Because of this, I cannot provide a confident, source-backed answer for your issue with the selected value not displaying in the main select. If you are able to upgrade to Nuxt UI v3, you may want to use the documented labelKey and valueKey props for mapping option display and value fields, as these are supported and described in the current documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I have the select working, but the only issue is that the selectmenu doesn't render the selected option until the user clicks one of the options from the dropdown themselves. It doesn't actually render the option when it is programmatically set by the code.

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I'm sorry, but the knowledge sources do not contain specific information about USelectMenu in Nuxt UI v2 regarding the issue where the selected option is not rendered when set programmatically. The documentation for Nuxt UI v3 describes using v-model with the correct value and setting valueKey/labelKey for object options, but does not address this behavior in v2 or provide troubleshooting steps for this scenario. If you are able to upgrade to Nuxt UI v3, you may benefit from improved and documented support for programmatic selection using v-model, valueKey, and labelKey props. Otherwise, the knowledge sources do not provide enough information to offer a confident solution for this issue in v2. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
