cr-deploy-app

You need to install it globally and execute it in the directory, where the package.json of your app is located at. The tool will do a git pull, rewrite/rebranch the dependencies upon your selected environment, npm i the dependencies, find the app in the pm2 eco system and restart it.

$ npm i -g cr-deploy-app
$ cd ~/git/myApp && cr-deploy-app

ToDo:

Integrate option to do a hard-reset in local repository, to throw uncommited changes away and get able to do a git pull.
