If I call a service binding worker several times in a worker, each call can make 50 subrequests or they can only make 50 in total?
Sdoes anyone have an idea with disabling cache for certain endpoints for my cf workers hono-based server?
The issue is, i am using a KV storage to track the number of items are in processing stage for any user. and from frontend - there is a process counter api which returns the number of items in processing. (called at an interval of 2 seconds.)
When an process is complete - the number is update in kv storage. if I call the api from somewhere else like let's say postman or terminal using curl - the response is up to date number.
but for browser it takes like 10 more seconds to get that updated number.

MIs there a way to test a tail worker locally by having it bind to itself?
Sbut if I call do a cUrl call from terminal it returns updated value.
only for the same browser it takes longer.

Jif I wanted a worker to refresh OAuth tokens, what is the best strategy? just set it up on an hourly cron schedule?
ZOn free workers, that's probably the best strategy. If you have the paid plan though, a better option is durable object alarms. That'll let you set the exact time you want to refresh that specific token at, and automatically retries if it fails.
ZIf you are on the free plan and storing the tokens in KV, watch out that there aren't two things writing to it at the same time. Since KV is eventually consistent, another worker running might not see the most up-to-date value and might update the value incorrectly.
Jso is your suggestion to save the Oauth token in a durable object? I haven't really used them before.
ACan I increase sub requests limit by calling them in another worker?
RHey, is
Object.groupBy avaliable inside the worker? it works locally but i want to be sure that it works when deployedRnice
RGuys, I'm getting:
You are logged in with an API Token. Unset the CLOUDFLARE_API_TOKEN in the environment to log in via OAuth.when trying to exec a command with the API token in .env file
RIt worked fine previously (wrangler 3.75.0) 
RAny thoughts?
MHi, can worker implement service to make request to another service that only receives request from static ip ?
IHi, I read somewhere that service bindings might become free because they're always loaded on the same machine. Any updates on this?
Ethey became free recently: https://developers.cloudflare.com/workers/platform/pricing/#service-bindings
Requests made from your Worker to another worker via a Service Binding do not incur additional request fees. This allows you to split apart functionality into multiple Workers, without incurring additional costs.
MIs it possible to send key metadata that will be part of the events passed to a tail worker? For instance an application request UUID? Obviously, we can pick up the
console.log()exceptions but is there a way to add a metadata field that's added to the event node of what's passed to the tail() method in a Tail worker?
CThere's a lot of magic. Did you try on your workers.dev or on a custom domain?
CI would try your workers.dev, Custom Domains can have things that effect outbound fetches like cache rules, I believe Transform Rules would also touch. Your SSL/TLS Mode also can transparently change the encryption regardless of what you specify in the fetch (ex: Flexible or Off will transparently downgrade https:// to http)
Pis it possible to improve cold start times
Pcold starts see ~500ms, subsequent requests are ~150ms-250ms
Emake the worker smaller?
PHow much does size impact it? It is a large application and there are some large WASM dependencies (mostly for OG image generation)
PGZ size is 2mb I think
Elarger workers have longer cold starts, its one of the main causes but isnt the only cause (theres also v8 optimisations for cpu-heavy workers as leo says)
Pis there something I can do to fix that? I assume my main option is to seperate the worker into smaller pieces?
Pog is 27% of the bundle
Esplitting would work if each execution only needed some or none of the split workers, wouldnt be very useful if you needed to call all of them anyway
Ejust generally the only advice in this case is to make the worker smaller, how to do that will depend on the exact use-case
PThis would be the case. OG image generation is just needed when another website requests it
Ethen yeah try splitting OG image gen into its own worker
PI'll try that ig
Etest whether that helps and iterate accordingly
Eyou should connect to the split worker over a service binding to remove any network latency from the worker-to-worker fetch
PCould I also do workers routes? If I had one worker pointing to
/api/*/api/og/*
POne bundle size fantasy (unrelated to OG generation) I've had for years is macros in bundlers
Eoh rite you said the website is requesting the worker, in that case yeah you can do routes like that
Eits if you wanted your main worker to act on the response that youd have to use service binding since same-zone fetch doesnt work
Pye
Ebut if its just a different api endpoint by all means use routes like that
Pdoes a worker created with the dashaboard support ES modules? Or can that be done only via wrangler? I see the wrangler.toml file at creation but I can't edit it. Can it be done after creation?

Mi will rename it if it helps
Mthat did not help, also o1js needs threads so i might have to go to another solutions
GHey guys, is anyone else's audit throwing a high severity error with cloudflare/vitest-pool-workers & wrangler.
GGWrangler is on version 3.75.0.
Sanyone know if it is possible to use fetch with a proxy now? I tried
https-proxy-agent but getting TypeError: Cannot convert object to primitive value when calling new HttpsProxyAgent(proxyUrl)
