gulp-htmlbars

Warning

This repo is going to be deprecated and merged its features into gulp-handlebars. At the same time, I would be joining as a maintainer of gulp-handlebars repository along with lzad. Migration should be done by the end of March, 2015.

To compile htmlbars and handlebars templates for gulp

Usage

Install gulp-htmlbars as a development dependency:

npm install --save-dev gulp-htmlbars

Compiling handlebars templates for the browser. (AMD format)

gulp-wrap-amd, is maintained by @phated and myself, can be used to safely convert templates into AMD syntax available for use in the browser.

First, install development dependencies:

npm install --save-dev gulp-htmlbars gulp-wrap-amd gulp-concat gulp

Given the following directory structure:

├── gulpfile.js              # Your gulpfile
└── source/                  # Your application's source files
    └── templates/           # A folder containing templates named with dot notation
        └── header.hbs       # A template that will be available as MyApp.templates.home.header

To compile all templates in source/templates/ to build/js/templates.js under the MyApp.templates namespace:

gulpfile.js

Compiling htmlbars templates for the browser. (AMD format)

gulpfile.js

gulp.task('templates', function(){
  gulp.src('source/templates/*.hbs')
    .pipe(htmlbars({
      templateCompiler: require('../bower_components/ember/ember-template-compiler')
    }))
    .pipe(wrap({
      deps:         ['exports'],          // optional, dependency array
      params:       ['__exports__'],      // optional, params for callback
      moduleRoot:   'source/templates/',  // optional
      modulePrefix: 'rocks/'              // optional
    }))
    .pipe(concat('templates.js'))
    .pipe(gulp.dest('build/js/'));
});

Compiling templates for use in Ember applications

See the ember-rocks for a full example of compiling templates for Ember.

You can use gulp-replace to modfiy the output, and then use within Ember, Ember-Rocks, or Ember-Cli:

gulpfile.js

gulp.task('templates', function(){
  gulp.src('source/templates/*.hbs')
      .pipe(htmlbars({
        templateCompiler: require('../bower_components/ember/ember-template-compiler')
      }))
    .pipe(wrap({
      deps:         ['exports'],          // dependency array
      params:       ['__exports__'],        // params for callback
      moduleRoot:   'source/templates/',
      modulePrefix: 'rocks/'
    }))
    .pipe(replace(
      /return export default/, 'return __exports__["default"] ='
    ))
    .pipe(concat('templates.js'))
    .pipe(gulp.dest('build/js/'));
});

Test

Before running the tests, need to run bower install at the root level, to have an Ember package in the local directory ("./bower_components"). HTMLBars is in a heavy development along with Ember project, each Ember release (Beta or Stable) will ship its bundled compiler for specific Ember version.

Once you have the Ember-template-compiler dependency ready, you could run

npm test  # kick start your local tests

API

htmlbars(options)

options.templateCompiler [required]

Type: Function Default: null

The file path of ember-template-compiler script which bundled with each version of Ember.js. Each Ember core version (beta or stable) will bundle the ember-template-compiler.js script to compile HTMLBars template.

Ex: templateCompiler: require('../bower_components/ember/ember-template-compiler')
