[back-end cli] Gracefully restart on code changes #23

Closed dxps closed 5 months ago

dxps commented 8 months ago

While the server can gracefully shutdown if it receives the expected signal, cargo-watch does not have an option to specify which signal to send to the running (server) process, nor wait for it to shutdown (see this).

The alternative is to use watchexec.

The watchexec way works like this:

❯ watchexec --exts rs --restart -- cargo run --bin server -- --port 9091 --log debug
[Running: cargo run --bin server -- --port 9091 --log debug]
