How to handle query parameters in prod environment ?

Hello everyone ! Here is the context: I use Nuxt3 with Vue3. When doing using the command nuxi dev, my query params are well handled. Here an example of a valid request in local env: http://localhost:8000/foo/bar/test?param=value. So when everything is fine, I build my app and send it to a S3 Bucket with the option "Static Website Hosting". And now comes the problem: when I call the same request, it redirects me to /foo/bar/test/ for reasons I don't understand. The only way for me to make it possible is to call https://domain.foz/foo/bar/test/index.html?param=value and now everything works fine almost fine (query parameters are just ignored). In a way, I think that having this URL is not a problem in itself. There's no security problem or anything, and the end user certainly does not care about the format of the URL (am I wrong?). But it is a problem to me because I have a different behavior in different environments, making the transition more complex. Has anyone already had this problem? And knows how to solve it? Thanks for your time. Note: I use Route53 for the DNS, CloudFront as a CDN and S3 to storage the built application.

Hi @Jean-Baptiste R.. 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 don't have enough specific details to fully address your issue with query parameters in the production environment. However, I can provide some insights and suggestions that might help you troubleshoot the problem: 1. URL Trailing Slash: The behavior you're experiencing might be related to trailing slash handling. In one of the Stack Overflow posts, a user mentions adding trailingSlash: true to the router key in nuxt.config.js to ensure all URLs end with a trailing slash Stack Overflow Post (https://stackoverflow.com/questions/77064938). This might help with consistency between your local and production environments. 2. Redirects: Your issue could be related to redirects. In a YouTube video about Nuxt 3 redirects, it's mentioned that redirects are essential for web applications, especially when migrations happen or for SEO improvements YouTube [Nuxt 3]: Redirects in Nuxt 3 (https://www.youtube.com/watch?v=ALQcCDEusjI). You might want to check if there are any redirect rules in your Nuxt configuration or AWS setup that could be affecting your URLs. 3. AWS Configuration: Since you're using AWS services (S3, CloudFront, Route53), the issue might be related to your AWS configuration. One Stack Overflow post mentions creating a Lambda@Edge function for redirection when using S3 and CloudFront Stack Overflow Post (https://stackoverflow.com/questions/77064938). You might need to review your AWS setup to ensure it's correctly handling the URLs and query parameters. 4. Environment-aware Configuration: Nuxt provides ways to have environment-aware configurations. You could use this to set up different behaviors for development and production environments YouTube [Nuxt 3]: An environment-aware Nuxt Configuration (https://www.youtube.com/watch?v=DFZI2iVCrNc). This might help you address the differences you're seeing between local and production environments. 5. Static Hosting Considerations: When deploying a Nuxt application to static hosting services (like S3), there are specific considerations. The Nuxt documentation mentions that for static site generation (SSG), it will generate /200.html and /404.html single-page app fallback pages Nuxt Docs: Deployment (https://nuxt.com/docs/getting-started/deployment#learn-more). You might need to configure your S3 static website hosting to properly handle these fallback pages. Given the complexity of your setup and the lack of specific information about your Nuxt and AWS configurations, it's difficult to pinpoint the exact cause of the issue. You might need to review your Nuxt configuration, AWS setup, and possibly implement some custom handling for query parameters in your production environment. If the problem persists, you might want to create a minimal reproducible example and seek further assistance from the Nuxt community or AWS support, providing more details about your specific configuration and deployment process. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Calling https://domain.foz/foo/bar/test?param=value means calling an unknown file, but S3 knows that /foo/bar/test is a folder. So he redirects to /foo/bar/test/ (pointing to /foo/bar/test/index.html). That's why using the call /foo/bar/test/index.html?param=value fixes in some way the problem. I don't get why Lambda@Edge would help me with my problem. Not sure how the https://nuxt.com/docs/getting-started/deployment#learn-more can help me.

Let me check the knowledge base for you again. One moment! :books: ---------------------- Thank you for providing more context about your situation. I apologize for the confusion in my previous response. Let's focus on your specific issue with S3 static website hosting and Nuxt. You're correct that Lambda@Edge might not be directly relevant to your problem. I'll address your concerns more specifically based on the information you've provided. The behavior you're experiencing is indeed related to how S3 static website hosting works. When you request a URL without a file extension, S3 tries to serve an index document from that "directory". This is why you're seeing the redirect to the trailing slash version. To address this issue in the context of a Nuxt application deployed to S3, you have a few options: 1. Route Rules: Nuxt 3 provides a feature called routeRules which allows you to define custom behaviors for specific routes. You can use this to handle redirects or modify how certain routes are processed. Here's an example of how you might use it in your nuxt.config.ts:

   export default defineNuxtConfig({
     routeRules: {
       '/foo/bar/**': { redirect: { to: '/foo/bar/index.html', statusCode: 302 } }
     }
   })

   export default defineNuxtConfig({
     routeRules: {
       '/foo/bar/**': { redirect: { to: '/foo/bar/index.html', statusCode: 302 } }
     }
   })

This approach is mentioned in the Nuxt documentation on hybrid rendering (https://nuxt.com/docs/guide/concepts/rendering#edge-side-rendering). 2. Trailing Slash Configuration: As mentioned earlier, you can configure Nuxt to always use trailing slashes, which might help with consistency:

   export default defineNuxtConfig({
     router: {
       trailingSlash: true
     }
   })

   export default defineNuxtConfig({
     router: {
       trailingSlash: true
     }
   })

This is discussed in a Stack Overflow post about Nuxt canonical URLs (https://stackoverflow.com/questions/77064938). 3. Custom Error Page: You could create a custom 404 error page that handles the redirection client-side. This page would check the URL and append the trailing slash if needed. 4. CloudFront Configuration: If you're using CloudFront in front of your S3 bucket, you might be able to configure it to rewrite URLs or handle redirects more gracefully. This would require adjusting your CloudFront distribution settings. Regarding the deployment documentation you mentioned, while it might not directly solve your problem, it's relevant because it discusses how Nuxt handles static site generation, which is what you're essentially doing when deploying to S3. To maintain consistency between your development and production environments, you might want to consider using Nuxt's server-side rendering capabilities and deploying to a platform that supports it, rather than using S3 static website hosting. This would give you more control over how URLs are handled. If you must use S3 static hosting, you'll need to find a balance between Nuxt's routing behavior and S3's limitations. The routeRules approach mentioned above might be your best bet for handling this discrepancy. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

I'm not sure if my english is bad or if my problem is too picky... Can anyone take a look please? 🙂

query params won't work server-side if you prerender your page as there is no "corresponding page" to the query param if you need changes, apply them client-side or use SSR

Jean-Baptiste R.OP•5d ago

Oh well, thank you Hello, sorry to bother, can you explain what do you mean with "apply them client-side" please ?

manniL•4d ago

onMounted, check for query params and execute your logic problem: it won't be relevant for ssr

Jean-Baptiste R.OP•4d ago

Oh well, thank you ! I'm gonna switch to an EC2 instance and use SSR then
