Broken page when hosting as an SPA from S3

I'm building my app as an SPA and serving on an S3 bucket. I have ssr: false in my nuxt config and use generate to create the app bundle. However, after uploading the bundle to s3, the page doesn't render correctly. The index page is draw but without any styles loading Here is the page on load: image 1 Interestingly the response in entry.BwV9nihY.css returns the same content as index.html If I try to go to the uri of entry.BwV9nihY.css directly, I get a Nuxt 404 page: image 2. I've checked the s3 bucket and all the resources are present. I can also host the bundle locally using npx serve and that works as expected Any ideas? thanks

Hi @jamesathectare. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, I can offer some insights and suggestions for your issue with hosting a Nuxt SPA on S3. It seems that you're encountering issues with asset loading and routing when hosting your Nuxt SPA on S3. This is likely related to how S3 static hosting handles routing for single-page applications. Here are some points to consider: 1. SPA Mode Configuration: Make sure you have properly configured Nuxt for SPA mode. As you mentioned, you've set ssr: false in your Nuxt config, which is correct. 2. Generate Command: When using nuxt generate for an SPA, you need to ensure that only the necessary files are generated. According to the Nuxt documentation on static hosting, you can modify your nuxt.config.ts to clear routes and generate only the required files: 
   export default defineNuxtConfig({
     ssr: false,
     hooks: {
       'prerender:routes' ({ routes }) {
         routes.clear() // Do not generate any routes (except the defaults)
       }
     },
   })
   
   export default defineNuxtConfig({
     ssr: false,
     hooks: {
       'prerender:routes' ({ routes }) {
         routes.clear() // Do not generate any routes (except the defaults)
       }
     },
   })
This will produce three files: index.html, 200.html, and 404.html. 3. S3 Configuration: Ensure that your S3 bucket is properly configured for static website hosting. Set both the index document and error document to index.html. This allows S3 to serve your SPA correctly for all routes. 4. Cloudfront (if used): If you're using Cloudfront in front of your S3 bucket, make sure it's configured to forward all requests to the origin (S3) and use the origin's error pages. 5. Asset Loading: The issue with styles not loading and CSS files returning HTML content suggests a problem with how S3 is serving your assets. Double-check that the content types for your assets are set correctly in S3. 6. Routing: For an SPA, all routes should serve the index.html file, allowing the client-side router to handle navigation. Ensure your S3 bucket policy or Cloudfront configuration supports this. 7. Hash Mode for Router: Consider using hash mode for routing in your Nuxt app. This can help with S3 static hosting. You can enable it in your nuxt.config.ts: 
   export default defineNuxtConfig({
     ssr: false,
     router: {
       options: {
         hashMode: true
       }
     }
   })
   
   export default defineNuxtConfig({
     ssr: false,
     router: {
       options: {
         hashMode: true
       }
     }
   })
This information is based on insights from Alexander Lichter's video on building SPAs with Nuxt. 8. SPA Loading Template: If you want to show a loading screen while your SPA is initializing, you can use the spa-loading-template.html feature. Place this file in your app directory. More details can be found in the Nuxt experimental features documentation. If these steps don't resolve your issue, you may need to investigate further into your S3 configuration and how it's serving your assets. Consider using browser developer tools to inspect network requests and see exactly what's being returned for each asset. Remember, hosting SPAs on S3 can be tricky due to how S3 handles routing. You might need to combine S3 with a CDN like Cloudfront for more control over routing and caching behaviors. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
