Docker development node runner

An opinionated helper script for running a node app in a container during development.

Features

• Builds app and runs it
• When files change the app is killed, rebuilt and restarted
• If the app crashes the error is displayed and restarted when files change again
• To speed up expensive processes (e.g. preprocessing) app source code is copied from docker volume to local docker fs when files change

Requirements

NodeJS 6+

Usage

Apps expose functionality via package.json's scripts key:

• build: runs before the app is started and restarted
• start: starts the app
