Grunt: Watch multiple files, Compile only Changed

Question

I\'m new to Grunt, and so far I\'m enjoying it very much. I want Grunt to compile only the changed files when running grunt watch

In my Grunfile.coffee

Answer 1

I've finally found a real solution! And it's super simple too!

npm install grunt-newer --save-dev

Then in your Gruntfile (after loading the task in grunt):

watch:
    coffeescript:
        files: 'assets/javascript/**/*.coffee'
        tasks: ["newer:coffee"]

And that's it! The Awesome grunt-newer is awesome!
