You seem to especially target Vibe.d and your approach is based on *restarting* the server. It should be possible to do even better. Reload the server without stopping. Basic idea: Compile your server application as a shared library. Run a small wrapper, which uses the shared library. If a file changes, recompile the library and load it into the wrapper.

I see two problems:
1. It doesn't sleep for a few seconds after detecting that a file has changed,
so when you upload several changed source files, recompilation may start before
all of them are updated and either fail or produce something strange.
2. It works like this:
if (changed) { kill(projectName); build() run(projectName); sleep(); }
As a result, if the compilation fails, no application will be running. Probably
a better approach would be to have the application copied to a different place
and run from there. Then the loop would look like this (I also added an extra
unittest run before the running application is replaced):
if (changed) { sleep(); build() test() kill(dest) copy(projectName, dest)
run(dest); sleep(); }
In this approach your program is almost always running. You only have to figure
out how to provide `dest`. Perhaps via command line arguments where you provide
a path (or just a directory).
