Build Status

AngularJS template preloader. Load your html partials with your scripts. Reduce http requests, improve load time for views and directives with templates.

Getting Started

This plugin requires Grunt ~0.4.1

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 prangler --save-dev

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


The "prangler" task


In your project's Gruntfile, add a section named prangler to the data object passed into grunt.initConfig().

  prangler: {
    default: {
      options: {
        ngApp: 'myApp', // name of your angular module
        stripPathForTemplateId: 'src', // will remove src from the $templcateCache key
        stripFilenameExtension: false, // if true removes .html from $templateCache key
        filenameForTemplateId: false, // if true template loaded by filename

      files: {
        'dest/template.js': ['src/templates/*.html'],



Type: String Default value: 'app'

Name of your AngularJS module.


Type: String Default value: ''

Remove this String from beginning of template uris when store in AngularJS $templateCache.

If html partial is in src/templates/ and stripPathForTemplateId is set to 'src', the template will be stored to AngularJS $templateCache with key/uri templates/my-template.html


Type: boolean Default value: false

Remove filename extension from template uris when stored in AngularJS $templateCache. If html partial is at src/templates/mytemplate.html, it will be stored to $templateCache with key/uri src/templates/mytemplate


Type: boolean Default value: false

If true templates are stored in cache by filename and thus can be called in code via filename only. src/templates/mytemplate.html will be stored with mytemplate.html

Usage Examples

Default Options

Add templates to dest/templates.js from src/template/*.html.

  prangler: {
    default: {
      options: {
        ngApp: 'myApp',
        stripPathForTemplateId: ''
      files: {
        'dest/template.js': ['src/templates/*.html'],


In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
