Queue consumer from nextjs worker

Ah, so after some reading and asking perplexity, it seems like the following is the correct answer.

In this structure: 1. The next-app directory contains your Next.js application. 2. The workers directory contains separate directories for each Cloudflare Worker. 3. Each Worker has its own wrangler.toml file for configuration. 4. The Next.js app's wrangler.toml would include service bindings to the Workers. For example, in the Next.js app's wrangler.toml:

[[services]]
binding = "AUTH"
service = "auth-worker"

[[services]]
binding = "USER"
service = "user-worker"

[[services]]
binding = "DATA"
service = "data-worker"

[[services]]
binding = "AUTH"
service = "auth-worker"

[[services]]
binding = "USER"
service = "user-worker"

[[services]]
binding = "DATA"
service = "data-worker"

Then, in your Next.js API routes, you can use these service bindings. For example, in pages/api/user.js:

import { getRequestContext } from '@cloudflare/next-on-pages';

export default async function handler(req, res) {
  const { env } = getRequestContext();

  // Use the USER service binding
  const userResponse = await env.USER.fetch(req);
  const userData = await userResponse.json();

  res.status(200).json(userData);
}

import { getRequestContext } from '@cloudflare/next-on-pages';

export default async function handler(req, res) {
  const { env } = getRequestContext();

  // Use the USER service binding
  const userResponse = await env.USER.fetch(req);
  const userData = await userResponse.json();

  res.status(200).json(userData);
}

This structure allows you to separate concerns between your Next.js app and various Cloudflare Workers, while still enabling efficient communication between them through service bindings

Nest.js as Worker

Decorators and stuff probably won't work. Feels very hacky

Oh also, is there a way to limit

There isn't subrequest limits for service bindings (as a whole), since a service binding doesn't count as a subrequest

Oh, so if you use a service binding, it doesn't go over the internet and therefor doesn't get counted as a "subrequest". Therefor, you can stop & restart workflows forever

Wait really? Workflows don't have subrequest limits?

How would you ensure that there is always one and only one "Manager" workflow running at all times?
