It outputs, google node etc

so that's using the port?

well it outputs like 20 processes

Error: listen EADDRINUSE :::4000

this means that another process is using port 4000 already

I just restarted my mac, and it killed it automatically. But I think this is potentially an issue with prisma. Cause I am sure I did not start another process. And I believe this is the second time this happened. I can’t really file an issue though, cause I am not sure how to reproduce it. Although I might have an idea. This error occurred after, I had created a file lets say foo.ts and deleted it, and then created another file with the same name

Prisma does not start processes on port 4000 🙂

Maybe its graphql-yoga?

It's most likely you running

yarn start

twice. Happens to me almost daily 😛

Hmmm, maybe!
