Issues deploying to Azure SWA with Universal Rendering.
Hello, I'm just looking for some direction as I've hit a wall. I'm moving a Statically Generated Nuxt3 site hosted on Azure SWA to use Universal Rendering hosted on SWA. So far I'm only getting a blank screen after deployment. Can someone point me in the right direction to debug this, as I'm not familiar with Azure and what I've found here and via Google has not been helpful, since I seem to have everything configured correctly, env variables loaded in Azure, etc. Thanks for any help and direction. Update: I can successfully deploy my Nuxt app to Netlify without any issues, so seems to me I'm just missing how to get Azure functions to work for me.

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

When deploying a Nuxt 3 app with Universal Rendering (SSR) to Azure Static Web Apps (SWA), a blank screen after deployment can be caused by several issues. Based on the knowledge sources, here are some key points and directions to help you debug:
1. SSR vs. Static Hosting
Universal Rendering (SSR) requires a server to render pages on the fly. Azure SWA is primarily designed for static sites, and while it supports serverless functions, deploying a full SSR Nuxt app may require additional configuration. If you use
Make sure your environment variables are correctly loaded in Azure. In Nuxt 3, environment variables should be set in Azure's configuration and accessed via
- Check the browser console for JavaScript errors. - Inspect the network tab to see if your assets and API endpoints are loading correctly. - Review the Azure SWA logs for build or runtime errors. - Try running your app locally in production mode (
Ensure you are using the correct Nitro preset for your deployment. For SSR, you may need to use a Node.js server or another environment that supports server-side rendering, not just static hosting Hosting Providers. 5. SSR/SPA Mismatch
If you previously deployed a statically generated site and are now switching to SSR, make sure your deployment process is not serving old static files or misconfigured routes. Clear any cached files and ensure your build output matches your intended rendering mode. If after these checks you are still seeing a blank screen, try deploying your app to a different SSR-compatible environment (like Vercel, Netlify Functions, or Azure App Service with Node.js) to isolate whether the issue is with your app or the Azure SWA platform. I'm sorry, but the knowledge sources do not provide Azure SWA-specific SSR deployment steps for Nuxt 3. If you need more detailed Azure SWA configuration for SSR, you may need to consult Azure's own documentation or Nuxt community discussions for the latest guidance. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
Universal Rendering (SSR) requires a server to render pages on the fly. Azure SWA is primarily designed for static sites, and while it supports serverless functions, deploying a full SSR Nuxt app may require additional configuration. If you use
nuxi generate or nuxi build --prerender, Nuxt will output static HTML files and you won't be able to use server endpoints. For SSR, you should use nuxi build and ensure your deployment target supports running a server process, not just serving static files. If you deploy SSR output to a static host, you'll get a blank screen or errors because the server-side part is missing Universal Rendering.
2. Environment VariablesMake sure your environment variables are correctly loaded in Azure. In Nuxt 3, environment variables should be set in Azure's configuration and accessed via
process.env or useRuntimeConfig(). If they are not loaded, your app may fail silently. There are known issues where environment variables are ignored if not set up properly in the deployment environment Stack Overflow: Azure env vars.
3. Debugging Steps- Check the browser console for JavaScript errors. - Inspect the network tab to see if your assets and API endpoints are loading correctly. - Review the Azure SWA logs for build or runtime errors. - Try running your app locally in production mode (
nuxi build then nuxi preview) to see if the issue is specific to Azure.
