Restarting Nuxt due to error: Error: Nuxt instance is unavailable!

I already check, I don't have any import of nuxt in my app. It's all auto import.

----------------------
This error is related to the Nuxt instance being unavailable during hot module replacement (HMR) or hot reloading. It's a known issue that can occur in Nuxt 3 projects. Let's explore some possible causes and solutions:

Async code in composables:One common cause of this error is using async code in composables or components outside of the proper lifecycle hooks. As explained in the [Nuxt documentation](<https://nuxt.com/docs/guide/concepts/auto-imports#vue-and-nuxt-composables>), many Nuxt composables rely on being called in the right context, and using them asynchronously can lead to this error.To fix this, ensure that you're using Nuxt composables synchronously within the proper Vue and Nuxt lifecycle hooks.
Experimental asyncContext feature:If you need to use Nuxt composables in async functions, you can try enabling the experimental `asyncContext` feature. Add the following to your `nuxt.config.ts`:

   export default defineNuxtConfig({
     experimental: {
       asyncContext: true
     }
   })

   export default defineNuxtConfig({
     experimental: {
       asyncContext: true
     }
   })

This feature allows you to use Nuxt composables in async functions more safely.

Using runWithContextrunWithContext:
Another solution is to use the runWithContextrunWithContext function provided by Nuxt. This function allows you to run code with the Nuxt context, even in async functions. Here's an example:

   const { runWithContext } = useNuxtApp()
   
   await runWithContext(async () => {
     // Your async code using Nuxt composables here
   })

   const { runWithContext } = useNuxtApp()
   
   await runWithContext(async () => {
     // Your async code using Nuxt composables here
   })

Check for global installations:
As mentioned in a GitHub issue comment, sometimes this error can be caused by an old global installation of Nuxt Devtools. You might want to check if you have any global Nuxt-related packages installed and remove them.

kapa.ai•1/14/25, 4:03 PM

Update Nuxt and dependencies:
Ensure that you're using the latest version of Nuxt and its dependencies. Sometimes, updating to the latest version can resolve such issues.

If none of these solutions work, you might need to create a minimal reproduction of the issue to get more specific help. You can follow the guidelines in the Nuxt bug reporting documentation to create a reproduction and seek further assistance from the Nuxt community.

Remember, hot module replacement can be tricky, and sometimes the error might be caused by specific code in your application. If the issue persists, you may need to review your code, especially areas where you're using Nuxt composables or accessing the Nuxt instance.

I understand that enabling the experimental asyncContextasyncContext feature didn't resolve your issue. Let's explore some other potential solutions:

Use runWithContextrunWithContext:
As mentioned in the Nuxt documentation, you can try using the runWithContextrunWithContext method to ensure the Nuxt context is available. Here's an example:

   const nuxtApp = useNuxtApp()
   
   nuxtApp.runWithContext(() => {
     // Your code that requires Nuxt context here
   })

   const nuxtApp = useNuxtApp()
   
   nuxtApp.runWithContext(() => {
     // Your code that requires Nuxt context here
   })

This method is specifically designed to handle cases where the Nuxt instance might be unavailable.

Check for async operations:Review your code for any async operations that might be causing the context to be lost. Ensure that you're not using `await` before calling Nuxt composables, except in specific allowed cases like `<script setup>`, `defineNuxtPlugin`, or `defineNuxtRouteMiddleware`.
Investigate template normalization:Based on the error stack trace you provided, the issue seems to be occurring during template normalization. This could be related to how your templates or components are structured. Double-check your component files, especially any that might be using advanced features or plugins.
Update Nuxt and dependencies:If you haven't already, try updating Nuxt and its dependencies to the latest versions. Sometimes, these issues are resolved in newer releases.
Clear cache and node_modules:As a troubleshooting step, try clearing your project's cache and reinstalling dependencies:

   rm -rf node_modules .nuxt
   npm cache clean --force  # or yarn cache clean
   npm install  # or yarn install

   rm -rf node_modules .nuxt
   npm cache clean --force  # or yarn cache clean
   npm install  # or yarn install

Check for global installations:
As mentioned in a GitHub issue, sometimes global installations can cause conflicts. Ensure you don't have any global Nuxt-related packages installed.

If these steps don't resolve the issue, it would be helpful to create a minimal reproduction of the problem. This will allow the Nuxt community to provide more specific assistance. You can follow the guidelines in the Nuxt documentation for reporting bugs to create a reproduction.

Remember, the "Nuxt instance unavailable" error often relates to the timing and context of how Nuxt composables are being used in your application. A careful review of where and how you're using Nuxt-specific features, especially in relation to async operations, might reveal the root cause.

I understand you've updated to the latest Nuxt version and are now experiencing multiple errors during hot reloading. This is a common issue that can occur after updating Nuxt. Let's explore some potential solutions based on the information provided in the knowledge sources:

Vite compatibility issue:
There's a known issue with Vite 6 and Nuxt 3.15.0. As mentioned in a GitHub issue comment, you can temporarily resolve this by pinning Vite to version 5. Add the following to your
```
package.json
```
```
package.json
```
:

   "pnpm": {
     "overrides": {
       "vite@6.0.6": "vite@5.4.11"
     }
   }

   "pnpm": {
     "overrides": {
       "vite@6.0.6": "vite@5.4.11"
     }
   }

Then run npx nuxi upgrade --forcenpx nuxi upgrade --force to apply the changes.

Downgrade Nuxt:If the Vite pinning doesn't work, you might need to temporarily downgrade Nuxt to version 3.14. This has resolved issues for some users, as mentioned in the same GitHub issue.
Clear cache and reinstall dependencies:Sometimes, updating can leave remnants of old versions. Try clearing your project's cache and reinstalling dependencies:

   rm -rf node_modules .nuxt
   npm cache clean --force  # or yarn cache clean
   npm install  # or yarn install

   rm -rf node_modules .nuxt
   npm cache clean --force  # or yarn cache clean
   npm install  # or yarn install

Check for conflicting dependencies:Review your `package.json` for any dependencies that might be incompatible with the latest Nuxt version. Pay special attention to modules and plugins.
Verify component naming:As mentioned in a [Stack Overflow answer](<https://stackoverflow.com/questions/78760898>), there can be issues with component naming in newer Nuxt versions. Ensure your component names follow the correct format (e.g., `Mycomponentone` instead of `MyComponentOne`).

kapa.ai•1/14/25, 4:19 PM

Review your code for ES Module compatibility:
The latest Nuxt versions are more strict about ES Module compatibility. Check your code for any CommonJS syntax that might need updating, as suggested in the Nuxt ESM documentation.

If these steps don't resolve your issues, it would be helpful to provide more specific error messages. The Nuxt community is actively working on resolving issues with the latest versions, so you might also want to check the Nuxt GitHub issues for any recent reports similar to your situation.

Remember, when upgrading to a major new version, it's often a good idea to test in a separate environment before applying changes to your main project. This allows you to identify and resolve compatibility issues more easily.
