Running a Grunt build task on Heroku

Question

I am deploying a Node.js application on Heroku. My production deployment is based on a Grunt task that minifies js and css files, placing them in a /dist folder from which they are called.

How can I add this step on the Heroku deployment?

Answer 1

Use a postinstall script, as outlined in Heroku's DevCenter docs for node:

• https://devcenter.heroku.com/articles/node-with-grunt

eg:

"scripts": {
    "postinstall": "grunt uglify",
    "start": "node server.js"
  }
