My Basic Grunt Setup

gistfile1.js

module.exports = function(grunt) {

  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    uglify: {
      options: {
        banner: '/*! <%= pkg.name %> - v<%= pkg.version %> - ' +
          '<%= grunt.template.today("yyyy-mm-dd") %> */'
      },
      my_target: {
        files: {
          'dest/complete.min.js': ['scripts/*.js']
        }
      }
    },
    jshint: {
      files: ['gruntfile.js', 'srcipts/*.js'],
      options: {
        // options here to override JSHint defaults
        globals: {
          jQuery: true,
          console: true,
          module: true,
          document: true
        }
      }
    },
    watch: {
      options: {
        livereload: true,
      },
      all: {
        files: ['index.html','styles/*.css', 'scripts/*.js'],
        
      },
    },
  });

  grunt.loadNpmTasks('grunt-contrib-uglify');
  grunt.loadNpmTasks('grunt-contrib-jshint');
  grunt.loadNpmTasks('grunt-contrib-watch');

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

};

And package.json:
{
"name": "name",
"version": "0.0.0",
"devDependencies": {
"grunt": "~0.4.1",
"grunt-contrib-watch": "~0.4.0",
"grunt-contrib-uglify": "~0.2.0",
"grunt-contrib-jshint": "~0.6.0",
"matchdep": "~0.1.2"
}
}
