How to reload app on file save. aka. local development workflow

I've got single service that needs other services to function (database etc). I wonder what is good local development workflow for working with it.

My goal is to be able to quickly restart service on every file save to be able to quickly iterate during development.

• for node.js it'd be 1. stop server, 2. run node server.js again.

Right now, the only idea I have is git push deis master after every file change to see how it works together with all other local services - but it takes quite long time per iteration.
