AngularJS reducing HTTP request by combining javascript files

Question

Using angularJS is great. Although i see a problem in that i have the following files:

• app.js
• controllers.js
• filters.js
• directives.js
• services.js

That along with the actually AngularJS library files and perhaps jQuery is allot of http requests to the server.

Is there a way to combine all these together for a production environment? More to the point is there a specific AngularJS recommended way to do this?

Answer 1

The Grunt.js project is able to execute tasked commands such as minification and concatenation as I described above. The two grunt.js plugins with the widest support for these tasks are:

• Uglify (minification)
• Concat (file concatenation)

below is a sample task script for these:

module.exports = function(grunt) {

  grunt.initConfig({
    concat: {
      options: {
        separator: ';'
      },
      dist: {
        src: ['assets/**/*.js'],
        dest: 'assets/js/<%= pkg.name %>.js'
      }
    },
    uglify: {
      options: {
        banner: '/*! <%= pkg.name %> <%= grunt.template.today("dd-mm-yyyy") %> */\n'
      },
      dist: {
        files: {
          'assets/js/<%= pkg.name %>.min.js': ['<%= concat.dist.dest %>']
        }
      }
    },
  });

  grunt.loadNpmTasks('grunt-contrib-uglify');
  grunt.loadNpmTasks('grunt-contrib-concat');

  grunt.registerTask('default', ['concat', 'uglify']);

};

I dont usually answer my onw questions although i believe that relying on a server to compile, cache and check cached versions is not the way to go. Unnecessary processors and systems to maintain on a production environment.
