I have an usecase to cover. After every 1000 worker invocation I need to hit an api to external system. how can i do that? Any idea on this? Workers will as usual get data from user, the data will be stored on lets say d1. And after 1000 data I get from user, I need to push that data to external system. Any idea here?

Wow, debugging a CF Worker (typescript) in WebStorm for the first time is pretty powerful!

Better debugging for Cloudflare Workers, now with breakpoints

We provide many tools to help you debug Cloudflare Workers; from your local environment all the way into production. In this post, we highlight some of the tools we currently offer, and do a deep dive into one specific area - breakpoint debugging - a tool we recently added into our workerd runtime.

I believe the cache API respects the range header so should match the headers on

What happens if I use the cache-control request header and

cacheEverything: true

cacheEverything: true

cacheEverything: true

cacheEverything: true?

U

Unsmart•1/14/24, 8:30 PM

Yeah all cache everything does is allow caching all requests regardless of the extension. It will use the cache headers unless you specifically tell it to use a certain ttl

Hello, when I selected ssl encryption mode as Flexible, it gives unknown web server error (520 error).
with Full mode, it works well, please let me know what is wrong

MarkB•1/15/24, 12:05 AM

you recommend to use Full at least? with even free ssl

MarkB•1/15/24, 12:07 AM

I have only free ssl, so I am going to use flexible mode, Full with letsencrypt ssl is better than Flexible?

Hey i am new to cloudflare and workers. I want to implement schema markup for FaqElement via cloudflare worker.
I made a worker that has hardcoded script like this.

const schemaMarkup = {

        "@type": "FAQPage",
        "mainEntity": [

i just deploy the worker from wrangler, start the dev server, and then open a browser window using the dev tools

Arma•1/15/24, 6:32 PM

Look at the network tab of your browser, you should see 2 requests. From your description it definitely sounds like the browser is invoking the worker twice

A

Arma•1/15/24, 6:32 PM

which is fine

A

Arma•1/15/24, 6:33 PM

your worker need to check the path that is requested, and not send the email for any random path

yeah looks like maybe it's the favicon

By the way, you can send a response immediatedly and do the slow email sending in the background

by using
