404 errors during playwright navigation due to missing server redirect?

When I run my playwright tests on my SPA Nuxt application, I keep getting the message: Failed to load resource: the server responded with a status of 404 (Not Found) This happens when navigating to a page in the app using Playwright, like localhost:3000/mypage. Note however that the test and the navigation do succeed, but the error is always printed nonetheless. I assume this has something to do with the server serving the assets? Obviously there is no real mypage.html, so the 404 would be warranted, but usually servers are setup to reroute to the root for an SPA. Is there a setting I can change to remove this error from the tests (that doesn't include just hiding it by hacking the console.log 😛)

Hi @Ragura. 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 potential solutions to your issue with 404 errors during Playwright navigation in your SPA Nuxt application. The problem you're experiencing is likely related to how Nuxt handles routing for Single Page Applications (SPAs). In an SPA, all routes should indeed be redirected to the root index.html file, which then handles the routing client-side. Here are a few potential solutions and considerations: 1. SPA Loading Template: If you're using ssr: false for a client-side rendered app, Nuxt recommends placing an HTML file at ~/app/spa-loading-template.html. This file will be used to render a loading screen until your app is hydrated. While this might not directly solve your 404 issue, it's a good practice for SPAs with Nuxt SPA Loading Template (https://nuxt.com/docs/guide/concepts/rendering#universal-rendering). 2. Route Prerendering: You can configure Nuxt to prerender specific routes, which might help with the 404 errors. In your nuxt.config.ts, you can add:

   export default defineNuxtConfig({
     routeRules: {
       '/': { prerender: true },
       '/mypage': { prerender: true }
     }
   })

   export default defineNuxtConfig({
     routeRules: {
       '/': { prerender: true },
       '/mypage': { prerender: true }
     }
   })

This will generate static HTML files for these routes Prerendering (https://nuxt.com/docs/getting-started/prerendering). 3. Custom Server Middleware: You can create a custom server middleware to handle redirects. Create a file server/middleware/redirect.js:

   const redirect = (req, res, next) => {
     const uri = req.url;
     if (!uri.endsWith('/')) {
       res.writeHead(301, { Location: uri + '/' });
       res.end();
     } else {
       next();
     }
   };

   export default redirect;

   const redirect = (req, res, next) => {
     const uri = req.url;
     if (!uri.endsWith('/')) {
       res.writeHead(301, { Location: uri + '/' });
       res.end();
     } else {
       next();
     }
   };

   export default redirect;

This middleware will ensure that all routes end with a trailing slash, which can help with routing Stack Overflow - Nuxt Redirects (https://stackoverflow.com/questions/77064938). 4. Playwright Configuration: Ensure that your Playwright tests are configured correctly for Nuxt. You can use the @nuxt/test-utils/playwright package for better integration:

   import { expect, test } from '@nuxt/test-utils/playwright'

   test('test', async ({ page, goto }) => {
     await goto('/', { waitUntil: 'hydration' })
     // Your test code here
   })

   import { expect, test } from '@nuxt/test-utils/playwright'

   test('test', async ({ page, goto }) => {
     await goto('/', { waitUntil: 'hydration' })
     // Your test code here
   })

This configuration ensures that Playwright waits for the Nuxt app to be fully hydrated before proceeding Testing with Playwright Test Runner (https://nuxt.com/docs/getting-started/testing#testing-with-playwright-test-runner). 5. Nitro Route Rules: You can use Nitro's routeRules to configure how specific routes should be handled. For example:

   export default defineNuxtConfig({
     routeRules: {
       '/**': { ssr: false }
     }
   })

   export default defineNuxtConfig({
     routeRules: {
       '/**': { ssr: false }
     }
   })

This will ensure that all routes are handled client-side Nitro Route Rules (https://nuxt.com/docs/getting-started/server). If none of these solutions resolve your issue, it might be worth checking if there's a mismatch between your Nuxt configuration and your Playwright setup. Ensure that your Nuxt app is properly configured for SPA mode and that Playwright is interacting with it correctly. Remember, the 404 errors you're seeing might be expected behavior for an SPA, as the server doesn't actually have separate HTML files for each route. The key is to ensure that your server is configured to serve the main index.html for all routes, which then allows your SPA to handle routing client-side. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
