grunt-labjs-template

Create a LABjs template from list of javascript files

Getting Started

This plugin requires Grunt ~0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-labjs-template --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-labjs-template');

grunt-js-template task

Run this task with the grunt labjs_template command.

Example config

grunt.initConfig({

  labjs_template: {
              dev: {
                  src: 'src/templates/script_tags/scripts_template.html',
                  dest: 'src/templates/_scripts.html',
                  conf: '<%= concat.main.files[1].src %>',
                  dir: '{{ STATIC_URL }}'
              }
          }

});

grunt.registerTask('default', ['loadJavascript']);

<script>
(function (global, oDOC, handler) {
    var head = oDOC.head || oDOC.getElementsByTagName('head');

    function LABjsLoaded() {

        var $L = $LAB.setOptions({AlwaysPreserveOrder:true});

        if(!oDOC.addEventListener){

            if(!global.XMLHttpRequest){
                $L.script('//ajax.googleapis.com/ajax/libs/chrome-frame/1/CFInstall.min.js');
            }

            $L.script('//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js').wait(function(){

                    $L.script('<% print(grunt.script_dir); %>js/jquery-1.10.2.js');
                }
