I have a very large angular js application and I want to optimize its performance.
I want to create separate minified js files instead of creating a single file(scripts.js).

I found a solution to do this here.
It minifies the files but when I deploy it, I get invalid provider error.
Here is my grunt file (I have removed the code used for separate minifcation and posting my original grunt file.)

// Generated on 2016-06-18 using generator-angular 0.15.1

// # Globbing

// for performance reasons we're only matching one level down:

// 'test/spec/{,*/}*.js'

// use this if you want to recursively match all subfolders:

// 'test/spec/**/*.js'



module.exports = function (grunt) {



  // Time how long tasks take. Can help when optimizing build times

  require('time-grunt')(grunt);
