Nuxt 3 microfrontend integration

I have a Nuxt 3 base app and a Nuxt 3 micro app and I am using "@originjs/vite-plugin-federation". I have imported and loaded the micro app in the base app successfully. The only problem I have is that any component that is using slots, templates or any dynamic content, is not visible. No error is thrown though.
If I use static data and not slots or templates, everything loads perfectly.

Hi @eleni. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base.

----------------------
I apologize, but the knowledge sources provided do not contain specific information about integrating Nuxt 3 microfrontends using "@originjs/vite-plugin-federation" or issues related to slots and templates in this context.

However, I can provide some general insights based on the available information about Nuxt 3 components and slots:

Nuxt 3 does support slots and dynamic content in components. As mentioned in the Nuxt documentation on components, slots for client components work with certain experimental settings.
There might be issues related to the isolation of components when using microfrontends. The Nuxt documentation on server component context mentions that island components (which might be similar to your microfrontend setup) are isolated from the rest of the app.
The problem you're experiencing might be related to how the microfrontend integration handles dynamic content and slots across different Nuxt applications.

To troubleshoot this issue, you might want to:

Check if the problem persists when using only client-side components.
Verify if the microfrontend integration plugin supports passing slot content between different applications.
Ensure that all necessary dependencies and plugins are correctly configured in both the base app and the micro app.

If the problem persists, you may need to consult the documentation for "@originjs/vite-plugin-federation" or reach out to their support channels for specific guidance on handling slots and dynamic content in a Nuxt 3 microfrontend setup.

@kapa.ai When I am developing the micro app and I run it (npm run dev), everything shows perfectly. It is after I do npm run build and serve it, that this happens.

Let me check the knowledge base for you again. One moment!

----------------------
Based on the information you've provided and the knowledge sources available, I can offer some insights into why you might be experiencing issues after building and serving your Nuxt 3 micro app, even though it works perfectly in development mode.

Build vs. Development Differences:It's common for applications to behave differently in development and production environments. The [Stack Overflow post about Nuxt 3 iframe PDF issues](<https://stackoverflow.com/questions/78297247>) highlights a similar scenario where content works in dev mode but not after building.
Server-Side Rendering (SSR) Considerations:Nuxt 3 uses server-side rendering by default. The [Github issue about Server Component and NuxtIsland with Slot](<https://github.com/nuxt/nuxt/issues/29354>) mentions build errors related to server components and slots. This could be relevant to your situation, especially if you're using server components or slots in your micro app.
Hydration Errors:The [Stack Overflow post about adding '@vite-pwa/nuxt' to a Nuxt 3 project](<https://stackoverflow.com/questions/78477429>) mentions hydration errors in production. These types of errors can cause components to not render correctly, which might explain why your dynamic content isn't visible after building.
Asset and Resource Handling:The [Stack Overflow post about Nuxt3 not resolving URLs passed as props](<https://stackoverflow.com/questions/77728394>) discusses issues with asset URLs in components. If your micro app relies on assets or resources, ensure they're being correctly resolved and bundled during the build process.

To troubleshoot this issue:

kapa.ai•1/28/25, 11:39 AM

Check your build logs for any warnings or errors that might indicate what's going wrong.
Ensure that all your dependencies are correctly specified and up-to-date.
Verify that your build configuration (in
```
nuxt.config.js
```
```
nuxt.config.js
```
or
```
nuxt.config.ts
```
```
nuxt.config.ts
```
) is correct for a production environment.
If you're using any experimental features, make sure they're properly configured for both development and production.

If the problem persists, you might want to create a minimal reproduction of the issue and seek help from the Nuxt community or the maintainers of the "@originjs/vite-plugin-federation" plugin.
