So CPU Time != Wall Time. Wall time is the actual time it takes (example: fetching a slow API is wall time) whereas CPU time is the actual work done by the CPU (i.e. hashing an asset is CPU intensive).

Isaac McFadyen•3/1/24, 7:19 PM

You get 10ms of CPU Time on the free plan. Even if you use more wall time, that's not CPU time and might still be allowed.

I

Isaac McFadyen•3/1/24, 7:20 PM

For example, if I fetch an external API that takes 45 seconds (on the free plan!) then it will work, because that's only maybe like 2ms of CPU time

Jjacob Yeah that's fine, looks like I might need a loader to support it. But I will loo...

My use case is a little bit different.
I need to make 10-15 API calls, but there's a rate limit of 1 API call per second.
What are all the possible solutions for this use case. Can you please suggest.

I

Isaac McFadyen•3/1/24, 7:23 PM

So this is allowed on the default Workers Free plan. Each API call might take a second, but you can easily make 10 or 15 of them on the Free plan because each call might only take 1ms of CPU time. It's good to test, you might need the paid plan, but likely not.

The API will get resolve in few ms. But then I have to wait for 1s before I make another one. So my question is will this 1s be treated as CPU time or wall time?

Isaac McFadyen•3/1/24, 7:25 PM

Wall time. CPU time is only the work that the actual CPU does (processing power, basically) so waiting for a second or waiting on an outgoing request will not consume CPU time.

when doing local worker development and using R2. I see that

.wrangler/state/v3/r2

.wrangler/state/v3/r2

.wrangler/state/v3/r2

.wrangler/state/v3/r2 is created containing my files, but are they only accessible through the binding? does wrangler cli run some alternative local server to serve files ?

C

Cyb3r-Jak3•3/1/24, 8:12 PM

Wrangler local commands should also use it or you can use miniflare directly

B

bun•3/1/24, 8:12 PM

to launch a r2 server ?

C

Cyb3r-Jak3•3/1/24, 8:17 PM

What do you mean by launch a server? Wrangler doesn’t have a way to serve them over http if that’s what you’re looking for

W

Walshy•3/1/24, 9:53 PM

you should set

compatibility_flags = ["nodejs_compat"]

compatibility_flags = ["nodejs_compat"]

rather than node_compat

(compat flags uses runtime node APIs,

node_compat

node_compat

uses polyfills)

then usage would just be like

import { createHash } from 'node:crypto';

function sha256(text) {
  return createHash('sha256').update(text).digest('hex')
}

import { createHash } from 'node:crypto';

function sha256(text) {
  return createHash('sha256').update(text).digest('hex')
}

import { createHash } from 'node:crypto';

function sha256(text) {
  return createHash('sha256').update(text).digest('hex')
}

import { createHash } from 'node:crypto';

function sha256(text) {
  return createHash('sha256').update(text).digest('hex')
}

Basically one of the things I'm going to need to build soon is outbound webhooks. With the new queue stuff it should be pretty straightforward to do.

Kind of? An external request should never be able to access any internal services directly, unless you naievely pass them through
