--node-compat

worked out of the box. Is this really the way to go when using any third party library that uses node modules?

Hello, I’m Allie!•1/17/24, 4:42 PM

Maybe? I generally just avoid deps that require Node, but I know that isn't feasible for everyone

Hello, I’m Allie!•1/17/24, 4:42 PM

Don't remember the exact reasoning for it, but iirc it was something about Node's APIs not being JS-standard, so they wanted to scope them

Hello, I’m Allie!•1/17/24, 4:43 PM

Just like how non-standard Cloudflare APIs that require an import are scoped

Given there’s 4,521 dependents on the “crypto” lib on npm (which is built into Node now, yes) still meowlul

kian•1/17/24, 4:46 PM

TIL they literally nuked it other than a deprecation README

kian•1/17/24, 4:47 PM

Anyways, there was work in Wrangler to make it automatically turn crypto -> node:crypto (and others) for you but that isn't done yet

HHello, I’m Allie!Maybe an `esbuild` alias? https://esbuild.github.io/api/#alias

DenniOP•1/17/24, 4:50 PM

How do I supply arguments like this to esbuild through wrangler?

DenniOP•1/17/24, 4:50 PM

I'm not very familiar with TS build tools at all

DDenni How do I supply arguments like this to esbuild through wrangler?

Hello, I’m Allie!•1/17/24, 4:55 PM

You have to install

esbuild

esbuild

, then run the build yourself

Hello, I’m Allie!•1/17/24, 4:55 PM

There are like 3 things you can configure on esbuild when using the

wrangler

wrangler

provided one

HHello, I’m Allie!You have to install `esbuild`, then run the build yourself

DenniOP•1/17/24, 4:59 PM

That sounds like it would need a lot of config to get it to work with cloudflare

DenniOP•1/17/24, 5:01 PM

It seems the library I'm using does have a browser version you can build yourself. I'll look into how to integrate that

Advany•1/17/24, 5:10 PM

anyone else not able to deploy? sees like wangler login isn't working. Gate way error 504

DDenni It seems the library I'm using _does_ have a browser version you can build yours...

DenniOP•1/17/24, 5:13 PM

Okay, this doesn't quite seem to work either. Is it possible it's trying to access browser APIs that CF Workers don't have access to?

DenniOP•1/17/24, 5:14 PM

I'm not getting any build errors this time, it just doesn't work and throws warnings and tries to reconnect

kian•1/17/24, 5:15 PM

What package are you trying to use?

DenniOP•1/17/24, 5:17 PM

I'm using gramjs, a Telegram client. It has both a node and browser version

DenniOP•1/17/24, 5:17 PM

CF Workers might not be the best way to do this but I need something to automatically send a couple of telegram messages once per day

Advany•1/17/24, 5:26 PM

working again

Deo Kumar•1/17/24, 8:15 PM

Does wasm binaries bundled using

wrangler deploy

wrangler deploy

count in 1MB limit?
Because my worker.js size is 940KiB and overall size including wasm is 2.3MiB after bundling but it throws the error

workers.api.error.script_too_large

workers.api.error.script_too_large

kian•1/17/24, 8:27 PM

Yes

Advany•1/17/24, 9:48 PM

mhhh... if I am doing wrangler dev (and I dont do await on a htmlrewrite transform), it doesnt work. But it works deployed when doing return rewriter.transform(response);

Advany•1/17/24, 9:50 PM

I should just do await then right?

Advany•1/17/24, 9:51 PM

In the docs there is no await so thats why I was confused!

kian•1/17/24, 9:54 PM

You can return a Promise from an async function (i.e the

fetch

fetch

handler) without awaiting it

Advany•1/17/24, 10:11 PM

yeah, I do that... but seems like when using locally (so without --remote) the htmlrewriter isn't running. Le tme create a sample project to show it

AA•1/18/24, 1:52 AM

need to find a nice way to create apis that can be consumed by workers. openapi seems so heavy these days.. tho maybe hono makes it nice

AA•1/18/24, 1:57 AM

using stuff like zodios/trpc and messing around with mono repos also an option i guess

Bob•1/18/24, 11:49 AM

I'm having a hard time grasping the worker concept of environment variables. I'm using hono and I want to create a variable outside hono 'c.env' context. I don't understand Where this 'env' comes from.

Bob•1/18/24, 11:53 AM

for example:

app.use('/input/*', bearerAuth({ TOKEN }));

app.use('/input/*', bearerAuth({ TOKEN }));

I would normally use 'process.env.TOKEN'

BBob for example: `app.use('/input/*', bearerAuth({ TOKEN }));` I would normally use ...

Hello, I’m Allie!•1/18/24, 12:02 PM

You would do something like

app.use('/input/*', (c, next) => bearerAuth({ c.env.TOKEN })(c, next));

app.use('/input/*', (c, next) => bearerAuth({ c.env.TOKEN })(c, next));

HHello, I’m Allie!You would do something like ```ts app.use('/input/*', (c, next) => bearerAuth({ ...

Bob•1/18/24, 12:04 PM

My hero! What it I just want to access them outside of the "app." context?

BBob My hero! What it I just want to access them outside of the "app." context?

Hello, I’m Allie!•1/18/24, 12:04 PM

Like, in the global scope? Is this for initializing a client or something?

Bob•1/18/24, 12:04 PM

yes

BBob yes

Hello, I’m Allie!•1/18/24, 12:04 PM

Then you would initialize it within the

app

app

scope, then store it in a global

Hello, I’m Allie!•1/18/24, 12:05 PM

You could also use an AsyncLocalStorage to have it accessible globally(but that requires a compat flag)

Hello, I’m Allie!•1/18/24, 12:05 PM

But note, env vars are only ever available in the context of handling an incoming event

Hello, I’m Allie!•1/18/24, 12:05 PM

For example, you can't just pull a secret on startup

Bob•1/18/24, 12:11 PM

ok, I guess I just have to repeat initialization code for each endpoint. I'm using Langhian and have to initialize the embeddings and vector store for every GET and POST. Is there a best practice?

BBob ok, I guess I just have to repeat initialization code for each endpoint. I'm usi...

Hello, I’m Allie!•1/18/24, 12:24 PM

You can have a single global variable to store them in, so they only get initialized once

Hello, I’m Allie!•1/18/24, 12:24 PM

Though note too that isolates aren’t reused very often, so it might be over optimization

Hello, I’m Allie!•1/18/24, 12:24 PM

Generally, they are only reused by the same client, in a limited period of time afterward

Bob•1/18/24, 12:35 PM

yeah, It's more so about not having to repeat myself. I guess I can write a little wrapper function with all the static pieces and just call them with the envs with each event.

Bob•1/18/24, 12:37 PM

Thanks for your help!

igorpancheski•1/18/24, 1:35 PM

Guys, i want to create a serverless function for converter .pst to .mbox, but the filesize can be heavy like 30gb or more. I need to understand if i can get a super power high processor and RAM for function on Workers of cloudfare. i finded to do it on aws or google but. i need a machine more stronger for my MVP. I don't care at first moment with the price i just want to validate my idea. someone has some option for helpme ?

zegevlier•1/18/24, 1:37 PM

Workers are extremely unsuited for high memory requirement applications. They're not the right fit for your project

conqr ᯅ•1/18/24, 4:31 PM

worker failed to prewarm: Service Temporarily Unavailable

conqr ᯅ•1/18/24, 4:31 PM

That might work, but it seems a little weird to me that this is the best way to do it when `--node-c
