If you’ve written your Node.js app in coffeescript entirely and at the time of deploying on Heroku wondering how heroku would execute your coffee code, then here’s the simple process that you need to follow.
coffee-script npm package into your
package.json or just install it with the
--save flag that’ll auto-add anyway.
$ npm install --save coffee-script
Then, instead of using the
node command in your
Procfile use this –
web: coffee server.coffee
I’m assuming that the
server.coffee is your node app script that needs to be executed to start your web app. Hope this quick tip helps some!
