How to test multiple workers locally
Hi,
I would like to migrate from Supabase to Cloudflare and replace all my Edge functions (20+) with Workers. However, I couldn't figure how to run multiple workers locally that's accessible through the same port with different path names to call the different services.
Based on the documents, it seems that I need to launch each Worker one by one in different terminals, which seems to be extremely tedious when testing an application that requires access to all the services.

I see, that's quite difficult to develop then. Does that mean that people just test the functions remotely?
I have been messing around with running workers using Lerna and it sort of works. There are issues when starting multiple workers in parallel so I have been using sleep statements as a workaround,
"dev": "sleep 1 && wrangler dev.
Edit: This was a port related issue, could just specify the local port for each worker and inspector-port

It seem like Cloudflare does recognize Lerna could be used with workers though...
