How to run 3x pinia functions that the rest of the site relies on?

What'd be the go-to method for this? we've got 3x functions, in 3 different pinia stores, that everything else on the site relies on, core settings fetched from apis, things fetched from cms to place into header and such, just wondering what the defacto method would be for this?

Hi @kb. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The recommended approach in Nuxt (with Pinia) for initializing core data that the rest of your site depends on is to fetch this data as early as possible in your app's lifecycle—typically in your root component (like app.vue) or in a plugin. This ensures that the data is available before any dependent components render. A common pattern is to use the callOnce utility in your app.vue to call the fetch actions from your Pinia stores. This guarantees that each fetch runs only once per server/client context, preventing duplicate requests and ensuring SSR compatibility. Here’s how you might do it: 
<script setup lang="ts">
const storeA = useStoreA()
const storeB = useStoreB()
const storeC = useStoreC()

await callOnce(async () => {
  await Promise.all([
    storeA.fetchCoreSettings(),
    storeB.fetchHeaderData(),
    storeC.fetchCmsContent()
  ])
})
</script>
<script setup lang="ts">
const storeA = useStoreA()
const storeB = useStoreB()
const storeC = useStoreC()

await callOnce(async () => {
  await Promise.all([
    storeA.fetchCoreSettings(),
    storeB.fetchHeaderData(),
    storeC.fetchCmsContent()
  ])
})
</script>
This pattern ensures all three essential fetches are completed before the rest of your app renders, making the data available globally. This is similar to the old nuxtServerInit pattern from Nuxt 2, but adapted for Nuxt 3/4 and Pinia. You can read more about this approach in the official docs under State Management > Initializing State. If you need even more control or want to run this logic in a plugin, you can also use a Nuxt plugin to trigger these fetches on app initialization, but the app.vue + callOnce pattern is the most straightforward and idiomatic for most use cases in Nuxt 3/4 with Pinia.
Most of the time, you will want to initialize your state with data that resolves asynchronously. You can use the app.vue component with the callOnce util to do so.

Let me check the knowledge base for you again. One moment! :books: ---------------------- In Nuxt 3, the app.vue file is optional. If you don't have an app.vue file, Nuxt will use its own default version. However, you can add your own app.vue at the root of your project if you need to customize the global structure or run logic (such as initializing core data) at the top level of your app. This is a recommended place to put code that should run once when your app starts, like the initialization of essential Pinia store data that the rest of your site relies on.
Nuxt 3 provides a central entry point to your app via ~/app.vue. If you don't have an app.vue file in your source directory, Nuxt will use its own default version. This file is a great place to put any custom code that needs to be run once when your app starts up, as well as any components that are present on every page of your app.
Nuxt 3 Migration: Pages and Layouts So, if you need to run global initialization logic, you can simply create an app.vue file at the root of your project and use it for this purpose. If you don't need any custom global logic or structure, you can omit it and let Nuxt handle it for you with the default. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
