Is there a work around for Worker Routes to run on home page requests with query params but not ru

Is there a work around for Worker Routes to run on home page requests with query params but not run on everything else?
Example: If I add a route for

*/*

*/*

it will run for all traffic (this is too broad), if I add one for

*/

*/

it will only run for the home page if there aren't any query params.

Can I do something with workers to allow custom domains for my app?
Like, something to make CNAMEs so that others can add it to their domain and that way their domain becomes an alias of mine?

Route pattern matching considers the entire request URL, including the query parameter string. Since route patterns may not contain query parameters, the only way to have a route pattern match URLs with query parameters is to terminate it with a wildcard, *.

The problem with this is that if I only want to run the worker on the home page and I terminate the route with a wildcard it matches 100% of all URLS, not just the home page route

. E.G- it will match

/something/i/dont/want

/something/i/dont/want

too

Chaika•7/10/24, 5:36 PM

yea, I get what you want, some people have asked for that before, it's just as the docs say though

Chaika•7/10/24, 5:37 PM

if you a paid zone you could work around it with snippets (although they're alpha/not recommended for production yet), either doing the logic in a snippet directly or fetching a worker on a subdomain, and then they're powered by ruleset engine so you could have it check only if any query params are set (len > 0), or for a specific one, etc

i think to begin with 100 is nice

so basically the users can add my fallback origin to their dns

with this workers function

whois | API man•7/10/24, 5:39 PM

and it will consume my worker requests right?

Chaika•7/10/24, 5:40 PM

yes, although a point worth mentioning is you have to add them as a custom hostname (in dash or via api) first, and then they cname (or do the prevalidation first to avoid downtime) and get activated

whois | API man•7/10/24, 5:41 PM

ye basically give them my the option to use my cname and if they want they can just validate their own

whois | API man•7/10/24, 5:41 PM

but

whois | API man•7/10/24, 5:41 PM

i think for my app it would be better to do prevalidation first

Hi everyone,
I'm currently working on adding a custom domain feature to my project, and I could use some assistance. Here are the details of my setup:
I have an Angular site hosted on Cloudflare Pages with the following DNS settings for my domain (site.com):

CNAME --- site.com --- pages.dev
 A --- fallback --- 192.0.2.1 
CNAME --- cd --- fallback.site.com

CNAME --- site.com --- pages.dev
 A --- fallback --- 192.0.2.1 
CNAME --- cd --- fallback.site.com

I have enabled Cloudflare for SaaS and added "fallback.site.com" as the fallback origin for site.com.
I also have a domain (test.com) and have created a custom hostname (app.test.com). I generated a TXT validation and added the TXT record and a CNAME record (CNAME --- app --- cd.site.com) to the test.com DNS records.
Additionally, I have a worker that routes requests coming to site.com. The worker acts as a reverse proxy, serving content from either the Pages site or a WordPress site, while keeping the URL in the browser as site.com/*. However, when I try to handle the custom domain and serve a page from site.com/custom-domain, the URL in the browser changes from app.test.com to site.com/custom-domain.
Here I have attached index.js and wrangler.toml:

And here is the wrangler.toml configuration:

How can I ensure that the content of the pages is loaded while keeping the URL the same in the browser(app.test.com)? Any help or guidance would be greatly appreciated!
Thanks in advance for your help!

My Cloudflare Worker is blocking fetch requests originating from Vercel or Netlify. How can I stop this?

dsmith1024•7/11/24, 2:46 PM

can a tail worker be the same codebase as the original worker? like is it possible to just call the same workers fetch handler? I don't want to stand up a new worker right now and hoping to kinda hack it.

Also do they get triggered in local dev with wrangler?

dsmith1024•7/11/24, 3:35 PM

doesnt seem to be working, but im not quite sure how to tell honestly. Tailing the logs I dont see the tail worker called, but not sure if that would actually show.

brighter•7/11/24, 7:55 PM

anyone got

pino.transport

Is there an easy way to tell if the worker is being served from wrangler dev? I have a use case where I want to know if the worker is actually deployed to allow/disallow localhost in CORS. Right now I'm using the CF-Ray header to detect this, but it doesn't work if the wrangler dev is using a remote deployment

You should check your WAF logs. Probably where the request is being blocked.

This basically means that smart placement is slower than the normal placement, or am I wrong? D1 database is hosted in East US and my service that's fetching data from this worker every minute is also located in the East of the US.

Chaika•7/12/24, 3:17 PM

If you have a D1 DB attached and you turn on Smart Placement, it overrides its location to be closest to the D1 DB, and D1 Requests aren't going to show up in any of the Request Duration/Subrequest charts I don't think

Cyb3r-Jak3•7/13/24, 12:02 AM

You can check there is an API token with WAF rules and check the validity of the token in your middleware

johtso•7/13/24, 3:44 AM

umm, is it normal for

performance.now()

performance.now()

to return 0 if you call it in your module's initialisation?

johtso•7/13/24, 3:44 AM

I feel like it should never return 0..

johtso•7/13/24, 3:45 AM

seeing as performance.timeOrigin = 0

Chaika•7/13/24, 3:48 AM

it only advances on i/o: https://developers.cloudflare.com/workers/runtime-apis/performance/
(and the timeOrigin in Workers is 0 as described in there as well)

CChaika it only advances on i/o: https://developers.cloudflare.com/workers/runtime-apis/...

johtso•7/13/24, 3:51 AM

But shouldn't it still be initialised with a sensible time?

johtso•7/13/24, 3:52 AM

It breaks Effect's clock implementation because it tries to calculate the origin based on performance.now() at initialisation

Chaika•7/13/24, 3:53 AM

there's some comments in workerd about it: https://github.com/cloudflare/workerd/blob/882c33f4ce989cd140da00695cd75f066558fc41/src/workerd/api/global-scope.h#L86C1-L86C8

johtso•7/13/24, 3:55 AM

The thing is it doesn't behave like Date.now().. date doesn't return zero at initialisation
