🐛 Bug Report

Environment

• operating system: MacOS (Catalina, 10.15.1)
• output of rustc -V: n/a
• output of node -v: v10.17.0
• output of wrangler -V: 1.8.0-rc.1

Steps to reproduce

With dev running, add a console log statement inside the worker. Save. The console log does not show up. Restart dev, the console log is there.

What did you expect to see?

The new console log should show up in the terminal without dev needing to be restarted.

What did you see instead?

The new console log does not show up in the terminal.

@yet-another-dev - the reload itself can take a bit since it needs to re-build and upload the worker to the cloudflare api (wrangler dev is not offline). Does it work if you wait a bit until you see a Built successfully message?

Does it work if you wait a bit until you see a Built successfully message?

No, I'm afraid not.

I'm having the same issue here, also with the console.logs.

Ok - I'm able to reproduce with a Workers Site project, but not with a regular worker. Going to investigate this.

It seems like this has to do with how make_service_fn works - I need to force it to update quicker than it is. Waiting on a response from some Rust experts 😄
