MI guess i could use esbuild --define to replace
process.env.X
HALS is a good choice there
HThough as you noted, you need to make sure it isn’t called directly in the global scope
Mthanks @HardlyWorkin' or workin hard. do you know if there are any examples floating about of using ALS instead of "env drilling" for want of a better term
Ehas anyone been able to find an answer to this? find the
Would you like to report this error to Cloudflare?
Ahi am new to clould flare and learning, i have deployed my first default worker and as soon as i deployed it it already had like 20 requests, without me doing anything, is that normal ? what are those requests ?
CBots scrape the SSL certificate logs and send requests to new hosts.
AThanks, they are sure fast starting scraping, like instant, hope they do not eat up too much of the free tier
CIt can help to disable the workers.dev subdomain for a bit when first creating the worker. Means the bots will get rejected when they first try it
Nfor storing profile pictures and other kinds of pictures (like product images uploaded), should I use R2 or Cloudflare Images (stored)?
Nwhich is more worth it?
AThanksss for the tip !
SHey everyone, MailChannels will be discontinuing our free API service as of June 30th. Details are in this knowledgebase article: https://support.mailchannels.com/hc/en-us/articles/26814255454093-End-of-Life-Notice-Cloudflare-Workers

Since launching our free email sending API for Cloudflare Workers customers, we have been proud to provide a simple yet effective solution to deliver messages from Workers code with a minimum of se...
SStarting next week, you may notice a small fraction (1%) of your connections are rejected with an error message containing a link to the same announcement. Any messages that are accepted by the service will be delivered as usual and we will continue to provide support as usual until the final day of service.
JAh, good to hear. We've been advising people to avoid this partnership for quite some time, so it's good to get an official End of Life notice.
JNot sure why you can't access the community, but I've made the announcement there so folks are aware: https://community.cloudflare.com/t/mailchannels-end-of-life-notice-migrate-now/658638
SThanks, @James. I figured you would take up the challenge.
JHappy to help 
JWhat's the best way to cache data from D1 used by a api request via workers?
I need simple data from the D1 database like userCount via a api request, but quering the database on each request doesn't seem optimal.
Is there a way to save the data in some global variable or some caching mechanism so the d1 database isn't queried often?

PHello, is it ok to use the same worker for
scheduledfetch
ZThat is perfectly fine to do. There aren't any real downsides, other than that the two calling methods will both be listed in analytics for the same worker. If your scheduled takes a lot more CPU time, that would throw off your averages for request CPU time usage.
AI noticed new error recently when deploying with
My worker is relatively small with a short list of dependencies (prisma, @planetscale/database, zod), and source map comes out to be around ~7MB. The 5MB limit seems very low. I had to disable source_maps for this worker, but I'd imaging a simple worker that is just proxying calls to a database is going to be a frequent use case of workers.

Kive made a normal worker with eventemitter and it works fine as long as its in the same file, when i put the
bot.on() function in an separate file it stops to work why is that?
Kthe
bot.on() function in a separate file, index.js and castam.js are in the same directory
Kas far as i can see eventemitter doesn't work between 2 files...
IIt looks to be because
castam.js imports from index.js but Workers always run the index.js, so castam never gets imported itself.IFor it to work the import would need to go the other way around somehow (index.js importing castam.js)
KOhhh i seee
Kokay so now i made a
emitter.js which has Eventemitter and ive imported the emitter.js into index.js and castam.js, still its like this...
Kdoesnt work i mean
Kignore the typo in bot.emit() its "hello" there ive fixed it
Ris it best to do a service bindings or the new native rpc calls for worker to worker
WYou'd need to use RPC over service bindings, RPC just provide an interface rather than the worker to worker part
Ryah i re-read the blog from april, makes sense now
ZNeed more RPC and stream r/w examples.FEels like I'm deciphering ancient spells from the few surviving pages of necronomicon
LI'm getting a lot of
Worker exceeded CPU time limit errors - is it safe to change from bundled to Standard? Is there anything that changes other than longer CPU limits?LAlso, are there any tips to help figure out what code the CPU limits are caused by?
KLimits only go up
KSubrequests go from 50 to 1,000, CPU time goes from 50ms to 30s, I don't think there's really anything else
KThere isn't really any good solution for it - you can try timing with
Date.now()
LOkay I see, thank you. I recall that there was an issue with
Date.now()asyncI meant for local development, Date.now() isn't limited there
KIn deployed Workers it will still only progress on IO
LAh ok that makes sense. Thanks for the help
KMost Workers only really run into CPU issues when parsing a lot of data or stuff like WASM
LI'm thinking I might be hitting CPU limits with the
HTMLRewrtier but having a hard time proving it. Its tough to know when this issue started happening too since the exception causes the worker to crash and not send any logs.LI was thinking we could put another worker infront of this worker to detect if there are any issues. Do worker subrequests share the same memory/cpu limits?
KHow can I prevent Cloudflare Workers from counting Unauthorized accesses as requests?
KI am limited to 100,000 requests per day.
