Fetching and storing JWKS within a worker

Working on a project building a small application that requires user authentication to interact with various endpoints hosted on CF Worker. Using Auth0 for all user management, and last night was able to get a simple "Hello World" setup that can authenticate a user's token when interacting with the worker Part of the auth process is using a JWKS provided by Auth0 to verify the provided access token. The JWKS is easily available through an Auth0 endpoint, and currently things are wired up to just fetch the JWKS on every request. Obviously, this won't scale beyond even a couple users before Auth0 starts to rate limit the JWKS endpoint - so some sort of caching of the JWKS seems to be necessary. Still very new to CF Workers, but my initial thought was to use either KV or Durable Objects to store the JWKS object, with a wrapper that can handle updating it when necessary. Durable Objects seem to be the right approach here, but I'm curious for others thoughts for this use case (or if I'm just fundamentally misunderstanding the problem and there is an easier solution!)...

Rename a worker

I have a worker created using Wrangler and it is up and running on CloudFlare serving requests. I'm wondering what would it happens if I rename the worker name in the TOML configuration file. will the worker be recreated from scratch traffic shifted transparently to it? Will this renaming have impact on the traffic?

Worker using multiple modules in a single bundle

Hi, I've recently upgraded my wrangler from 3.52.0 to 3.56.0 (no code is changed), and I'm getting an error when I run wrangler dev:

✘ [ERROR] workerd/jsg/_virtual_includes/jsg/workerd/jsg/modules.h:443: warning: NOSENTRY Worker using multiple modules in a single bundle.

I wonder what may be the possible cause? ...

Custom domain worker DNS record

Hi, I created a worker and connected it to a custom domain that I added in cloudflare through dashboard. This created a worker DNS record automatically with the proxy enabled and can't be modified. Is there a way to disable the proxy and will it still work?

Smart Placement "too smart"?

The docs https://developers.cloudflare.com/workers/configuration/smart-placement/#unsupported-back-end-services mention that smart placement is not supported for globally distributed services, and specifically mentions Google APIs. If I'm connecting to a Cloud Firestore database in a specific region via the Cloud Firestore REST API, will smart placement ignore this? The Firestore database is always located in a specific region. Also based on the following:...

Can I specify language output for image-to-text?

Default return is in English, can I specify which language to output in? Didn't see anything in docs. If not, I'll just use the translation AI models but figured I would ask!...

Parsing email

I've tried to use a couple of popular email parsing libraries (textract, mailparser) to parse the raw text received by an email worker, but so far I haven't found anything compatible with the CF runtime environment. For example, I get errors like below during deploy. Missing pacakges incude node:buffer, node:stream, crypto, path, etc. ```...

How to add jsx support for React-email in workers?

I can't run my worker in dev (or remote) since I'm using JSX to render my emails. How would I go about fixing this? I'm using the renderAsync method so it's not a node issue.

Programmatic PDF generation on worker

Hi everyone, I've been looking for some way to generate PDFs within a worker script. Currently I use the browser rendering api to create PDFs of a page but according to the dashboard a single invocation takes 6 seconds... There must be a better and faster way right?...
