[DUX-2458] Documentation for running a server #315

Open 9999years opened 2 months ago

  1. Are there any new configuration options or commands to enable server mode?
  2. Is there documentation available on how to set up ghciwatch for running and auto-reloading a web server or similar application?
  3. Are there any best practices or examples you can share for using this new functionality?

  1. Not really
  2. You probably want something like --test-ghci DevelMain.update
  3. Running a command that writes to stdout asynchronously (like Yesod does, see https://github.com/ndmitchell/ghcid/issues/298) might cause problems (ghciwatch works by parsing the GHCi stdout), so we really want to redirect logs to a file and have ghciwatch read them from there (see #226).
