I'm building a thing where that will be hosting customer websites using cloudflare pages. For exampl

I'm building a thing where that will be hosting customer websites using cloudflare pages. For example, my website is kelly.com and using cloudflare pages the URL for a customer's pages website might be customer.pages.dev.

To set up a custom domain, a customer might set up a CNAME from example.customer.com to customer.pages.dev. This is ok although I don't want customers to need to use customer.pages.dev, I'd rather they have customer.kelly.com.

My current plan to resolve this is to add a custom domain to the pages project, customer.kelly.com, and tell the customer to use customer.kelly.com, so it would be example.customer.com -> customer.kelly.com -> customer.pages.dev.

Is there any issue with this approach? I want to try it out and am getting

CF Pages uses CF for SaaS under the hood, which basically has an allowlist of all the accepted host headers/subdomains allowed to use it. It's seeing example.customer.comexample.customer.com and saying "hey that's not on our list", and it would only allow it as a Verified Custom Domain if it was pointing direct

Your options basically are:

Use CF Pages Custom Domains up to the limit: https://developers.cloudflare.com/pages/platform/limits/ (depending on plan), have customers cname to pages.dev
Use Cf for SaaS, but in order to do that you'd need to have a Worker in the middle and pay for each request as an invocation. Snippets (Workers with more limits, limited to Pro, but no per request costs) may help with this but they're in Alpha/not recommended for production and still rolling out

@Chaika Thanks. I just tested adding example.customer.com as another custom domain, so now I have two: example.customer.com and customer.kelly.com. Based on your reply I think this would not work, but there is no longer the error and it's working. Does that make sense?

Chaika•5/24/24, 12:38 AM

Makes sense in the way that Cf for SaaS validation is quirky lol, must be from the http validation? Eitherway if you go that way you'd hit the 100 Custom Domain Limit (on free) at some point and have to go someway else, and you won't be able to support root domains (customer.com)

busterroniOP•5/24/24, 12:39 AM

why would I hit the 100 custom domain limit? The 100 custom domain is per website, and this is 2 domains per website.

Chaika•5/24/24, 12:39 AM

no, it's per Pages Project

Chaika•5/24/24, 12:39 AM

busterroniOP•5/24/24, 12:39 AM

yes, each customer gets their own project

Chaika•5/24/24, 12:40 AM

then you'll have to get the soft 100 project limit raised if you haven't already

busterroniOP•5/24/24, 12:40 AM

sure, I can do that once I get to 100 projects, good problem to have!

Chaika•5/24/24, 12:41 AM

yea, I would have them CNAME to the pages.dev directly as well instead of through your domain

busterroniOP•5/24/24, 12:42 AM

I don't want to do that, because it means switching from cloudflare pages later would mean every customer needs to switch

busterroniOP•5/24/24, 12:42 AM

also I might want to switch a customer's pages website without having them update their dns

Chaika•5/24/24, 12:44 AM

not sure if cnaming to your domain which cnames to the pages.dev would work long term, I know there was some restrictions being put in place about using IPs that aren't assigned to your site and at least documented the only real-time validation is off the DNS record target. It might be defaulting to/using http validation maybe but feels sketchy, eitherway using it not in the documented/supported way

busterroniOP•5/24/24, 12:44 AM

that's why I'm asking here, maybe someone from the cloudflare team can say if it's ok

when I run wrangler pages deploy .wrangler pages deploy ., and I have a

functions

directory with typescript files in there, does wrangler build & bundle my typescript code on its own?

Avi•5/24/24, 12:46 AM

i assume so, the docs just don't explicitly state this... like what version of typescript does it use?

Sometime the static assets on pages starts returning internal errorinternal error until I redeploy the project. For example, this one -

A error occurred on robots.txtrobots.txt, then all the static assets stopped working from last 12 hours.

Example request -

https://app.dayschedule.in/static/img/logo.png

https://app.dayschedule.in/static/img/logo.png

Code (using Hono) -

app.get(`${WEBSITE_URL}/static/*`, async (ctx) => {
  const { url, cf } = ctx.req.raw;
  cf.cacheEverything = true;
  cf.cacheTtl = 60 * 60;
  const asset = await ctx.env.ASSETS.fetch(new Request(url, { cf: cf }));
  if (asset.status == 200 || asset.status == 304) {
    return asset;
  } else {
    throw new HTTPException(400);
  }
});

app.get(`${WEBSITE_URL}/static/*`, async (ctx) => {
  const { url, cf } = ctx.req.raw;
  cf.cacheEverything = true;
  cf.cacheTtl = 60 * 60;
  const asset = await ctx.env.ASSETS.fetch(new Request(url, { cf: cf }));
  if (asset.status == 200 || asset.status == 304) {
    return asset;
  } else {
    throw new HTTPException(400);
  }
});

The same starts working, if I re-deploy

is the dashboard failing for anyone else? First I couldn't login, after entering user and pass the loading icon went on forever, reloaded 3 times and then I was presented with a form to send a message, then I could login. Now I changed HSTS setting and some other stuff and I've been getting some errors, I've setup email routing and activated the email but it lists nothing, that is without talking about how laggy the whole dashboard is

If it's IN- and you open the pdf, should be a Pay onlinePay online button in there, and assuming your restriction was purely that billing issue, it should resolve it. I know in the past with the old system people reported paying unpaid invoices and their acct was unlocked instantly, but I'm not 100% sure with the new system

is it possible to chain multiple commands in the build command? I tried to use source $(poetry env info --path)/bin/activate && pelican contentsource $(poetry env info --path)/bin/activate && pelican content to activate the environment first before running pelican, but it cannot find source

Pol•5/26/24, 6:37 PM

Hey! Is there any way to trigger the pages build on a PR after manual approval, or after some actions finished successfully?

Pol•5/26/24, 6:38 PM

AFAIK it's possible with gh actions, but I cannot get CF to not start the build automatically

Walshy•5/26/24, 7:14 PM

you can use a deploy hook

Walshy•5/26/24, 7:14 PM

but it doesn't accept arbitrary branches so you'd need to make one per branch

Pol•5/26/24, 9:13 PM

I've realized that what I really want is CI to know if building fails. I'm just going to make it a gh action, and then maybe do something to deploy a preview

Thank you anyways for the help

Hello, ive been facing a CORS issue when trying to add a custom domain with cloudflare for my backend which is hosted on Render.

I tried adding the backend custom domain (api.mydomain.tld) on cloudflare which is sent requests from the frontend (mydomain.tld) which is also on cloudflare. The backend domain's content is hosted by Render. However, even after adding a wildcard to the allowed origins and them also being on the same domain name, for some reason I'm still facing CORS issues and i have no idea why. Both the api subdomain and the frontend domain have traffic proxied, which I've tried disabling for the api subdomain. Still not working. It leads to me believe its not an issue with my backend configuration. Has anyone faced this or know how to solve this issue?

Hi, has anyone been able to implement Baselime on a NextJS app in Cloudflare Pages?

This option doesn't work because it uses the `functions folder` and I use `next-on-pages` to build the app, and `these are incompatible` with each other (the same applies to HoneyComb): https://baselime.io/docs/sending-data/platforms/cloudflare/pages/
If I want to use OpenTelemetry for NextJS, I get errors like Module not found: `Can't resolve 'perf_hooks'`, and as I understand it, this is because Pages is not a full Node environment: https://baselime.io/docs/sending-data/languages/next.js/. Is there any way to resolve `perf_hooks`, `child_process`, `fs`, os, `http`?

Is there any solution to have observability in Pages? Any better documentation or example repo?

P.S. The NextJS app was generated with C3 and doesn't have any additional configuration other than what I'm trying to set up with Baselime.
