Hi @Adnan Erlansyah. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To auto-import file libraries and use them on your pages in Nuxt, you can utilize the utils/ directory. This allows you to create utility functions that will be automatically imported throughout your application without explicitly importing them each time. Here's how you can do it: 1. Create a utils/ directory in your Nuxt project if it doesn't already exist. 2. Place your utility functions or file libraries in this directory. For example:

// utils/myLibrary.ts
export const myFunction = () => {
  // Your function logic here
}

// utils/myLibrary.ts
export const myFunction = () => {
  // Your function logic here
}

3. Now, you can use these functions directly in your pages or components without importing them explicitly. Nuxt Documentation on utils directory (https://nuxt.com/docs/guide/directory-structure/utils) states: "Use the utils/ directory to auto-import your utility functions throughout your application." This means that any function exported from files in the utils/ directory will be automatically available in your .js, .ts, and .vue files. For example, you can use it in a page like this:

<template>
  <div>
    {{ myFunction() }}
  </div>
</template>

<script setup>
// No need to import myFunction, it's auto-imported
const result = myFunction()
</script>

<template>
  <div>
    {{ myFunction() }}
  </div>
</template>

<script setup>
// No need to import myFunction, it's auto-imported
const result = myFunction()
</script>

It's important to note that these auto-imports are only available within the Vue part of your app. For server-side utilities, you would use the server/utils directory instead. Nuxt Documentation on Auto Imports (https://nuxt.com/docs/guide/concepts/auto-imports) provides more details on how this feature works, including other directories like composables/ that also support auto-imports. Remember, while this feature is convenient, it's still a good practice to keep your code organized and avoid overusing global utilities when more specific imports would be clearer. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how about if I want to import file script like this. <script src="./face-api.min.js"></script> <script src="./rfc-scripts.js"></script>

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To import external script files like face-api.min.js and rfc-scripts.js in a Nuxt application, you have a few options. Let me explain the recommended approach using Nuxt Scripts: 1. First, you'll need to install the Nuxt Scripts module. You can do this by running:

npx nuxi@latest module add scripts

npx nuxi@latest module add scripts

Nuxt Scripts Installation (https://scripts.nuxt.com/docs/getting-started/installation) 2. Once installed, you can use the useScript composable to load your scripts. Here's how you can do it in your component or page:

<script setup>
const faceApiScript = useScript('./face-api.min.js')
const rfcScript = useScript('./rfc-scripts.js')
</script>

<script setup>
const faceApiScript = useScript('./face-api.min.js')
const rfcScript = useScript('./rfc-scripts.js')
</script>

3. If you want these scripts to be globally available across your application, you can configure them in your nuxt.config.ts file:

export default defineNuxtConfig({
  scripts: {
    globals: {
      faceApi: './face-api.min.js',
      rfcScripts: './rfc-scripts.js'
    }
  }
})

export default defineNuxtConfig({
  scripts: {
    globals: {
      faceApi: './face-api.min.js',
      rfcScripts: './rfc-scripts.js'
    }
  }
})

Nuxt Scripts Global Configuration (https://scripts.nuxt.com/docs/guides/global#usage) This approach offers several advantages: - Performance: Scripts are loaded only when Nuxt is ready, improving overall performance Nuxt Scripts Features (https://scripts.nuxt.com/docs/getting-started#nuxt-script-features). - Optimization: You can bundle these scripts with your application, reducing DNS requests Nuxt Scripts Bundling (https://scripts.nuxt.com/docs/guides/bundling#usage). - Control: You have more control over when and how the scripts are loaded. Remember, if these scripts are crucial for your application's functionality, you might want to consider bundling them or including them as part of your project's dependencies for better control and performance. Also, keep in mind that if these scripts modify the global scope or require specific loading order, you may need to adjust your implementation accordingly. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Why I'm getting this warn when imported it. WARN [Vue Router warn]: No match found for location with path "/auth/~/libs/face-api" this is the code on my login page.

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

<script setup>

// Title & Meta Tags
useHead({
  title: 'Login Page'
})

const faceApiScript = useScript('~/libs/face-api')

</script>

<style scoped>

</style>

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

<script setup>

// Title & Meta Tags
useHead({
  title: 'Login Page'
})

const faceApiScript = useScript('~/libs/face-api')

</script>

<style scoped>

</style>

Let me check the knowledge base for you again. One moment! :books: ---------------------- The warning you're seeing is related to how you're trying to import the script using useScript. The issue stems from the way Nuxt interprets the path you've provided. Let me explain the problem and provide a solution: 1. The warning "No match found for location with path "/auth/~/libs/face-api"" suggests that Nuxt is trying to treat the script path as a route, which is incorrect. 2. The ~ alias in Nuxt is typically used for imports within your JavaScript/TypeScript code, not for external scripts. To resolve this issue, you should use a relative or absolute path instead. Here's how you can modify your code:

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

<script setup>
// Title & Meta Tags
useHead({
  title: 'Login Page'
})

const faceApiScript = useScript('/libs/face-api.js')
</script>

<style scoped>
</style>

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

<script setup>
// Title & Meta Tags
useHead({
  title: 'Login Page'
})

const faceApiScript = useScript('/libs/face-api.js')
</script>

<style scoped>
</style>

In this corrected version: 1. We've changed '~/libs/face-api' to '/libs/face-api.js'. This assumes your script is in the public directory of your Nuxt project. 2. Make sure to include the file extension (.js) in the path. If your script is not in the public directory, you might need to adjust the path accordingly. Additionally, as mentioned in the Nuxt Scripts documentation (https://scripts.nuxt.com/docs/getting-started/confetti-tutorial#background-on-usescriptnpm), when working with local scripts, it's often better to include them as dependencies in your package.json file. However, for scripts that are not used often or are not critical to the application, using useScript can be a good alternative. If you continue to face issues, you might want to consider using the global configuration in nuxt.config.ts as described in the Nuxt Scripts Global Configuration guide (https://scripts.nuxt.com/docs/guides/global#usage). This approach can help avoid path-related issues:

export default defineNuxtConfig({
  scripts: {
    globals: {
      faceApi: '/libs/face-api.js'
    }
  }
})

export default defineNuxtConfig({
  scripts: {
    globals: {
      faceApi: '/libs/face-api.js'
    }
  }
})

This way, you won't need to use useScript in your component, as the script will be loaded globally. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai my libs folder is on the root project.

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand that your libs folder is located in the root of your project. In this case, we need to adjust the approach for loading the script using useScript. Here's how you can properly reference and load the script: 1. First, it's important to note that useScript is designed to load scripts from public URLs or from the public directory in your Nuxt project. It doesn't have direct access to files in your project's root or source directories. 2. To use a script from your project's root, you have a couple of options: a. Move the script to the public directory: You can move your face-api.js file from libs/ in the root to the public/libs/ directory. Then you can load it like this:

      <script setup>
      const faceApiScript = useScript('/libs/face-api.js')
      </script>

      <script setup>
      const faceApiScript = useScript('/libs/face-api.js')
      </script>

b. Use a build-time import: If you want to keep the script in the root libs/ folder, you should import it as a module instead of using useScript. This way, it will be processed by your build tool:

      <script setup>
      import '~/libs/face-api.js'
      </script>

      <script setup>
      import '~/libs/face-api.js'
      </script>

Note that this method doesn't give you the same level of control over script loading as useScript, but it will ensure the script is included in your build. 3. If you specifically need to use useScript and keep the file in the root libs/ folder, you'll need to configure your Nuxt project to serve this directory. This isn't a standard setup and might require additional configuration in your nuxt.config.ts file. For the best practices and easiest setup, I would recommend either moving the script to the public directory or using a build-time import as shown in option b above. Remember, when using build-time imports, you lose some of the benefits of useScript like controlled loading and optimization features mentioned in the Nuxt Scripts documentation (https://scripts.nuxt.com/docs/getting-started/confetti-tutorial#background-on-usescriptnpm). Consider if these features are important for your use case when deciding which method to use. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
