Can I run two workers from one monorepo?

I'm sure the answer is yes; I'm just wondering what the set up here would look like. If my repo was:

| worker1/
| - <all worker 1 files here - src/, wrangler.toml, etc.>
| worker2/
| - <ditto for worker 2>

| worker1/
| - <all worker 1 files here - src/, wrangler.toml, etc.>
| worker2/
| - <ditto for worker 2>

| worker1/
| - <all worker 1 files here - src/, wrangler.toml, etc.>
| worker2/
| - <ditto for worker 2>

| worker1/
| - <all worker 1 files here - src/, wrangler.toml, etc.>
| worker2/
| - <ditto for worker 2>

...how would I configure the action to read from those two top-level directories and build two distinct workers? Or would I need some sort of top-level Wrangler file? Just unable to visualise this.

You might be looking for Service Bindings (assuming you want to talk to the other worker) https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/rpc/

Sorry, not quite. I don't want one worker to talk to another. I just want two distinct workers to be managed from a monorepo. Right now I have a GH action which handles my worker deploy, but the worker assumes my repo is a single worker. I want that repo to contain two workers.

Sounds like you want Workers builds

I created an OpenAuth wrangler example that has 2 workers in a monorepo that may be helpful: https://github.com/mw10013/openauth-wrangler

There seem to be many ways to skin this cat so would be curious to know what you come up with.

Thanks guys, I'll take a look at these resources

Not sure if this is what you're asking about but I have all my workers (apps and apis) and packages (shared code like design library, typescript configs, helpers, db setup, etc.) in a monorepo using turborepo and pnpm workspaces. Each has a package.json and each worker has a wrangler config. they are separate entities and can share code through packages but each can be built and developed simultaneously by using turborepo.

if you want to setup preview deployments linked to git workflow you just need to go into worker settings on cloudflare dashboard and tell it where to run the deploy command.

Thanks, that's precisely what I'm after. Shortly before your message I found this page in the docs which also mentions Turborepo.
