/** | |
* Generates JavaScript version of HTML templates for AngularJS as part of a Grunt build | |
* | |
* Allows for bundling into multiple collections, for applications that are distributed across more than one page. | |
* | |
* Usage (in grunt.initConfig): | |
* | |
* html2js: { | |
* firstTemplateCollection: { | |
* src: ['<%= src.first %>'], | |
* dest: '<%= tmpdir %>/first' | |
* }, | |
* secondTemplateCollection: { | |
* src: ['<%= src.second %>'], | |
* dest: '<%= tmpdir %>/second' | |
* } | |
* } | |
* | |
* Be sure to add the 'templates' module as a dependency to your main Angular module | |
