Force redeploy of Node.js project on Heroku

Say you run git push heroku master and heroku responds with Everything up-to-date, but you want to force the re-deploy.

You might be adjusting config variables or testing with a new Heroku build pack.

Try this:

npm version build && git push heroku master

This command will increment the build version number in package.json and automatically commit and tag this change.

Saves a few keystrokes.
