Notification when build completes

[jamesarosen]

When developing a website with Viceroy, my current process is

1. run fastly compute serve --watch --watch-dir=src
2. edit a file in src
3. Viceroy automatically rebuilds the service
4. watch the logs for approximately 3 seconds until the HTTP server comes back up
5. switch to my browser and refresh

I'd love to receive a notification (e.g. a UNIX signal, touching a file, executing a command, or running a JS/TS/RS/WASM function) when the compilation is done and the server is back up. That would allow me to implement live-reload or even hot module replacement.

Until this, a workaround is to watch the files outside fastly compute serve, then restart fastly compute serve (without --watch), poll the HTTP server until it responds, then send the live-reload and/or HMR notifications to the browser.
