WebSocket Test examples

Are there any examples of test automation using websockets against a worker ? Don’t see any among https://developers.cloudflare.com/workers/testing/vitest-integration/recipes/ wondering how this is done

Env Variables in Workers Static Site [Vite + React]

Hey All, I am building a React + Vite app using cloudflare workers. It is a SPA with no workers backend. Is there any documentation around how to get environment variables into the frontend React app? I see everything is focused on how to get them into the workers runtime, but I am looking to access them from the bundled React code, where I normally use import.meta.env with vite

Node.JS Compatibility Error...

so following the video, I was expecting this error, but when I go to add that flag, then things have changed a bit. the flag that is suggested by the error, 'nodejs_compat' is no longer in the list, and instead, there are 2 similar available: with or without populate_process_env. see screenshot. I tried both of them, they don't work. I'm still getting that error. any idea?...

responseStreamDisconnected errors when making 6+ sub requests in worker

We are using ctx.waitUntil() API to make sub requests to send metrics/logs to DataDog, and when there are 6 or more requests, the request/response that is being returned is truncated. When looking at real-time worker logs, the outcome field is set to "outcome": "responseStreamDisconnected", . There are no other errors that are present. The format we are using to send metrics is ctx.waitUntil(async function() { return await fetch(...)});. The individual requests all function correctly, and I can reproduce this error by enabling any one of them, but if they are all enabled together, an error occured. We have the following wrangler.toml config:...
