Redirect WWW to not-WWW version

I had deployed on fly and with my custom domain (myweirdapp.com). I wanted to make sure that I don't have any www.myweridapp.com versions. At this moment every www url works in my app. I don't want that, I just want to have the non-www version. This www version should redirect to the non-www version. How can I archive this? Reason: Both versions of the URL are being indexed and making web scrappers dizzy.

Hi @NEROX. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To redirect the www version of your domain to the non-www version, you would typically need to configure this at the DNS level with your domain provider. However, Wasp currently does not provide built-in support for this type of redirection. You can set up your custom domain with Wasp and Fly.io by following the steps outlined in the Wasp documentation (https://wasp-lang.dev/docs/advanced/deployment/cli#using-a-custom-domain-for-your-app). This includes adding your domain to your Fly client app, adding the DNS records for your domain, and setting your domain as the WASP_WEB_CLIENT_URL environment variable for your server app. However, the redirection from www to non-www is not covered in these steps. This is typically handled by the server or the DNS provider, and it's not something that can be configured within the Wasp framework itself. I recommend checking with your domain provider or the Fly.io support on how to set up this redirection. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @NEROX, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

@kapa.ai Could you provide me more info about this and Dns, and Fly? Please! Don't be shy ;)

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Sure, I'd be happy to provide more information! DNS (Domain Name System) is the system that translates human-friendly domain names (like mycoolapp.com) into IP addresses that computers use to identify each other on the network. When you set up a custom domain for your app, you need to add DNS records that tell the DNS system where to direct traffic for your domain. In the context of deploying a Wasp app on Fly.io with a custom domain, you would typically need to add two types of DNS records: 1. An A record, which maps your domain to an IPv4 address. 2. An AAAA record, which maps your domain to an IPv6 address. The exact values for these records are provided by Fly.io when you add your domain to your Fly client app. You can do this by running the following command, replacing mycoolapp.com with your domain:

wasp deploy fly cmd --context client certs create mycoolapp.com

wasp deploy fly cmd --context client certs create mycoolapp.com

This command will output the instructions to add the DNS records to your domain. It will look something like this:

You can direct traffic to mycoolapp.com by:  
  
1: Adding an A record to your DNS service which reads  
  
 A @ 66.241.1XX.154  
  
You can validate your ownership of mycoolapp.com by:  
  
2: Adding an AAAA record to your DNS service which reads:  
  
 AAAA @ 2a09:82XX:1::1:ff40

You can direct traffic to mycoolapp.com by:  
  
1: Adding an A record to your DNS service which reads  
  
 A @ 66.241.1XX.154  
  
You can validate your ownership of mycoolapp.com by:  
  
2: Adding an AAAA record to your DNS service which reads:  
  
 AAAA @ 2a09:82XX:1::1:ff40

You would then need to add these records through your domain provider's DNS management interface. Finally, you need to set your domain as the WASP_WEB_CLIENT_URL environment variable for your server app. This is done to keep your CORS (Cross-Origin Resource Sharing) configuration up to date. You can do this with the following command, again replacing mycoolapp.com with your domain:

wasp deploy fly cmd --context server secrets set WASP_WEB_CLIENT_URL=<https://mycoolapp.com>

wasp deploy fly cmd --context server secrets set WASP_WEB_CLIENT_URL=<https://mycoolapp.com>

After these steps, your app should be available at <https://mycoolapp.com.> As for redirecting www.mycoolapp.com to mycoolapp.com, this is typically done with a CNAME record or a URL redirect record, but the exact method can vary depending on your domain provider. I recommend checking with your domain provider or the Fly.io support for specific instructions. You can find more information in the Wasp documentation (https://wasp-lang.dev/docs/advanced/deployment/cli#using-a-custom-domain-for-your-app) and the Fly.io documentation (https://fly.io/docs/networking/custom-domain/). I hope this helps!

Ok will check @kapa.ai I contacted my hosting provider (which I have my domain), they told me this: I recommend that you contact the support of that platform, the cname in www is an alias so that the domain can be opened using the prefix www, I see that you no longer have any CNAME records. Of course from the server/platform side where the domain is pointed, you must have the function to redirect from www to non www, in the Hostinger hosting is the htaccess to perform this type of redirection, on that platform you should consult with their support. Can you help me doing this with any redirect file with WASP or somethig with Fly.io? Do your best!

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand that you want to redirect from www to non-www for your domain. However, Wasp itself does not provide a built-in way to handle this redirection. This is typically handled at the server or DNS level. For Fly.io, they have a guide on how to setup a custom domain (https://fly.io/docs/getting-started/domains/), but it does not cover www to non-www redirection. However, Fly.io does support edge functions (https://fly.io/docs/app-guides/edge-functions/), which allow you to run code at the edge nodes of their CDN. You could potentially use an edge function to check the incoming request and if it's for the www version of your domain, redirect it to the non-www version. This would require writing some JavaScript code and deploying it as an edge function on Fly.io. Here's a very basic example of what the edge function might look like:

addEventListener("fetch", event => {
  event.respondWith(handleRequest(event.request))
})

async function handleRequest(request) {
  const url = new URL(request.url)
  if (url.hostname === 'www.mycoolapp.com') {
    url.hostname = 'mycoolapp.com'
    return Response.redirect(url, 301)
  }
  return fetch(request)
}

addEventListener("fetch", event => {
  event.respondWith(handleRequest(event.request))
})

async function handleRequest(request) {
  const url = new URL(request.url)
  if (url.hostname === 'www.mycoolapp.com') {
    url.hostname = 'mycoolapp.com'
    return Response.redirect(url, 301)
  }
  return fetch(request)
}

This code listens for incoming requests, and if the hostname is www.mycoolapp.com, it changes the hostname to mycoolapp.com and returns a 301 redirect response. Otherwise, it just forwards the request as is. Please note that this is a very basic example and might not cover all cases. You should test it thoroughly and adjust it to your needs. I recommend reaching out to Fly.io support for more detailed guidance on how to implement and deploy this edge function. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @NEROX, I seem to be having a bit of trouble.

@kapa.ai I'm using the OpenSaaS template, could you explaint to me where that code must be? Imagine I'm not very programmer, do your best!

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand that you're not very familiar with programming. Unfortunately, the solution I provided involves writing and deploying JavaScript code, which might be challenging if you're not comfortable with programming. The OpenSaaS template you're using is a Wasp project template. Wasp generates all the code it deploys to the .wasp/build folder. This includes both the web-app folder and the server folders. However, the redirection code I provided is not meant to be placed in the Wasp project itself. It's meant to be deployed as an edge function on Fly.io, which is a separate process. Edge functions in Fly.io are pieces of JavaScript code that run at the edge nodes of their CDN (Content Delivery Network). They're used to modify the behavior of HTTP requests and responses. In this case, the edge function would check if a request is for the www version of your domain, and if so, redirect it to the non-www version. To deploy an edge function on Fly.io, you would typically need to: 1. Write the JavaScript code for the edge function (like the example I provided). 2. Create a new Fly.io app for the edge function. 3. Deploy the edge function to Fly.io. This process involves using the Fly.io CLI (Command Line Interface) and potentially writing a fly.toml configuration file and a Dockerfile for the edge function. It's a bit advanced and might be difficult if you're not familiar with programming. I recommend reaching out to Fly.io support for more detailed guidance on how to implement and deploy this edge function. They might be able to provide a more beginner-friendly explanation or alternative solutions. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @NEROX, I seem to be having a bit of trouble.

Another Fly App??????? I think there should be a less cumbersome solution.

NEROXOP•4w ago

Seems like Wasp/opensaas also, issuing problems with www versions, https://www.wasp-lang.dev/ https://www.opensaas.sh/

NEROXOP•4w ago

🔄 Update: I no longer have a www version, but it does not redirect to the non-www version. The issue is half solved. (I had an A register pointing from www to the fly ipv4 address, just deleted and no more www. Will see how can I archieve the redirection) @kapa.ai I already don't have the www version, just deleted an A register and done. Now, how can I archive the redirection from www to no-www? It's mandatory to NOT deploy anything new to fly

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- If you don't want to deploy anything new to Fly.io, then the redirection from www to non-www should be handled at the DNS level. This is typically done with a URL redirect record, but the exact method can vary depending on your domain provider. Here's a general idea of how it might work: 1. Log in to your domain provider's DNS management interface. 2. Look for an option to add a new DNS record. 3. Choose a URL redirect record (the exact name might vary). 4. Set the name to www. 5. Set the destination URL to your non-www domain (e.g., <https://mycoolapp.com>). 6. Save the changes. After the DNS changes propagate (which can take up to 48 hours), any attempts to access www.mycoolapp.com should be redirected to mycoolapp.com. Please note that these are general instructions and might not apply exactly to your domain provider. I recommend checking with your domain provider for specific instructions. If your domain provider does not support URL redirect records, then you might need to consider other options. For example, some providers offer a web forwarding or domain forwarding service that can be used to redirect from www to non-www. I hope this helps!

@kapa.ai it should be A, AAA, CNAME or what? I'm not expert in dns

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The type of DNS record you need to set up for redirection from www to non-www typically depends on the capabilities of your domain provider. Here's a brief explanation of the different types of DNS records: - A record: Maps a domain or subdomain to an IPv4 address. - AAAA record: Maps a domain or subdomain to an IPv6 address. - CNAME record: Maps a domain or subdomain to another domain name. This is often used for subdomains like www. For redirection from www to non-www, you would typically use a URL redirect record, which is sometimes also called a URL record or a FORWARD record. This type of record is not standardized and might not be available from all domain providers. Here's a general idea of how to set up a URL redirect record: 1. Log in to your domain provider's DNS management interface. 2. Look for an option to add a new DNS record. 3. Choose a URL redirect record (the exact name might vary). 4. Set the name to www. 5. Set the destination URL to your non-www domain (e.g., <https://mycoolapp.com>). 6. Save the changes.

:shork: @kapa.ai my Hosting provider told me that this is not possible since the ip is not pointing an ip inside my Hosting provider (since is pointing to the ipv4 of my fly-client). I searched about "fly redirect www to non-www" and I found this: https://community.fly.io/t/how-to-redirect-from-non-www-to-www/5795/1 I resume you the topic: - Q: How to redirect from non www to www? - A: Currently, the only way to do this is by implementing the redirection logic in your app directly. Please, provide me the correct way to implement this in my Wasp app.

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand that you want to implement redirection from www to non-www directly in your Wasp app. However, Wasp currently does not provide built-in support for this type of redirection. This is typically handled at the server or DNS level. As mentioned in the Fly.io community post you found, the redirection logic would need to be implemented in your app directly. This would involve checking the incoming request and if it's for the www version of your domain, redirecting it to the non-www version. However, implementing this in a Wasp app could be challenging because Wasp is a framework for building web apps with React and Node.js, and it abstracts away many of the details of the underlying server. It doesn't currently provide a way to directly manipulate incoming HTTP requests. I recommend reaching out to the Wasp community or the Wasp developers for more guidance on this. They might be able to provide a workaround or suggest a future feature that could help with this. In the meantime, you might want to consider other options for handling the www to non-www redirection. For example, you could potentially use a service like Cloudflare, which provides URL forwarding rules that can handle this type of redirection. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @NEROX, I seem to be having a bit of trouble.

@kapa.ai As you told right now: " implementing this in a Wasp app could be challenging" so, it's not impossible. Start thinking of possible ideas!

:sadboi: Edit: Switching my nameservers to CloudFlare, let's see what I can accomplish from there (the domain is still with the same hosting provider).

NEROXOP•4w ago

Switched nameservers to cloudflare, will test if this Template of "Redirect from WWW to Root" work:

NEROXOP•4w ago

✅ Solved! Proof: https://www.toograded.com 1️⃣ Migrate your nameservers to Cloudflare, it's free. 2️⃣ Make sure that the "SSL/TLS encryption" in Cloudflare is set on: Full (strict) Mode (1st screenshot). By default is set in Flexible that causes redirect errors. 3️⃣ Create a redirect rule from the Templates (2nd screenshot). 4️⃣ If you want to preserve query strings, you must check that option (3rd screenshot). Click save. 5️⃣ Change the A Record pointing to Fly's ipv4 address (if before it was @ pointing to the ip, update the @ to www). Then you are left with the record as in the 4th screenshot. And it's done!:salute_right:

NEROXOP•4w ago

@Wasp Team Hey, due to the lack of information I have found on this topic, maybe this will be helpful.

miho•4w ago

@NEROX I wanted to suggest doing this but I thought it might be a big ask. I had success with this Cloudflare setup since they give the ability to redirect from www to non-www quite easily. Good job on figuring it out! Other than that - it's either having a redirect on the client i.e. detecting the hostname and then doing window.location or an another server app i.e. Fly app. that redirects.

martinsos•4w ago

Nice! @miho should we document this in some way? Maybe too niche for docs themselves, but ok for learning-materials? Or we can just leave it here in Discord? I see that @NEROX already made quite nice steps above + images.
