That's exactly what I was looking at. While I'm at it. In my use case, I'm planning to host pre-game lounges with chat, configurable options etc... so several different lounges. Managing the rooms won't be a problem, do we agree? I'd rather ask before jumping in

How to using caching on code-level? I need to cache the

getAuthUser(userId)

getAuthUser(userId)

function result on code level to avoid querying D1 again and again.

So, I built a get/set caching funcotion using a fake url, user/1, user/2 etc. But it doesn't seems to be working and I see undefined in response.

export const getCached = async (request: HonoRequest, key: string) => {
  const cacheUrl = new URL(request.url);
  cacheUrl.pathname = '/' + key;

  const cacheKey = new Request(cacheUrl.toString(), {

  const cache = caches.default;
  const response = await cache.match(cacheKey);

https://developers.cloudflare.com/images/transform-images/transform-via-workers/#warning-about-cachekey

Is the cacheKey only available for Enterprise customers for Image Transformations? I'm using a worker to proxy and transform Signed S3 images - so the source URL is unqiue for every request - even though the actual source url is different. I'd like to pass the unsigned version of the source url as the cacheKey to prevent transforming the same image over and over again. Is this possible?

Using Cloudflare Workers to transform with a custom URL scheme gives you powerful programmatic control over every image request.

Hi, after discovering JSRPC I have a few questions. I have a few unclear points about it. Is the simple fact of putting functions that extend WorkerEntrypoint enough to create a kind of "sub-function"? In the RPC documentation on Cloudflare, there is mention of Worker A and Worker B with a configuration in wrangler.toml. I don't quite understand how to set this up. Does this mean that I have to recreate a project to create another worker that I associate with my main worker (my API), or have I misunderstood the usage? Another quick question: is it good practice to put all my controllers used for route logic after validating the query format, or do I really need to set aside more demanding functions using RPC?

YYakuzo Hi, after discovering JSRPC I have a few questions. I have a few unclear points ...

D

DaniFoldiOP•4/18/24, 6:20 PM

let me try and answer all your questions in one go haha

yes, check the docs for how to import and link stuff, should be pretty simple
yes, jsrpc is between multiple workers - although you can bind a worker to itself, and use a different entrypoint, but that usually has other usecases (that require recursion or another 1000 subrequests)
I don't actually think there are many best practices around it yet, it's so new; the way I'd structure it is to have a few entrypoints (with route patterns) that do similar stuff (like one worker for main api, and a few more for any special functions such as webhooks if you have them), and pass them through a few other workers that handle CORS, auth, rate limiting, etc, and then business logic; you should be able to use jsrpc for all these, light and heavy tasks alike

DDaniFoldi let me try and answer all your questions in one go haha 1. yes, check the docs f...

Y

Yakuzo•4/18/24, 6:30 PM

Sorry for the complex question ( or rather questions ), it's true that rereading it wasn't easy to understand so gg.
Okay I'm starting to understand in this case. So yeah, if I start with a monorepo with one worker per API function, the repository will start to be titanic with each time the nodes modules to replicate for each worker.
It's actually quite new for Cloudflare but also for me, so I'm trying to figure out what would be the most optimized use case, knowing that reading the documentation, inter-worker requests look really fast, so I'm going to have to find a good use case.

D

DaniFoldiOP•4/18/24, 6:38 PM

I wouldn't really go that far as to deploy a worker for each api endpoint - you can also get multiple entrypoints per worker, which might be faster.

From optimization perspective, today, you're still charged for subrequests, which multiply your bill (there was a tweet but I couldn't find it now saying that those would be gone :soontm:), and loading workers into memory might take time, so at one end of the spectrum, you have DX, at the other end you have low cost (today) and tiny speed improvement

Y

Yakuzo•4/18/24, 6:52 PM

Okay I see, so it would be more for the use of functions that are least used, such as authentication. I'll have to figure out how to do it, but it looks really nice.

Can i use crypto and pg together?

M

node_compat = true
compatibility_flags = [ "nodejs_compat" ]
so confused between these two

As per documentation it says I need node_compat = true

Which is not working with crypto

Sadly you can't use

nodejs_compat

nodejs_compat

and

node_compat

node_compat

together.

node_compat

node_compat

is an old and legacy way for wrangler to inject polyfills and globals that emulate Node.js things.

nodejs_compat

nodejs_compat

is actually real node.js support for various modules, straight from the runtime. It's the recommended way to do things nowadays.

Sadly Hyperdrive requires

node_compat

node_compat

for the recommended

pg

pg

driver today. You can use

postgres.js

postgres.js

postgres.js

postgres.js with

nodejs_compat

nodejs_compat

, but it doesn't have full support with hyperdrive yet, mainly for things like caching.

yup, websockets also definitely work - I recommend taking a look at hibernated Durable Objects, they
