A Grunt plugin for pre-compiling Handlebars templates to a single concatenated file (or individually, whichever floats your boat).

Getting Started

*IMPORTANT: This plugin requires Grunt 0.4 or higher - it is recommended that you always run the latest version

Install the task:

npm install grunt-handlebars-compiler

Then add this line to your project's Gruntfile.js:


This allows you to use the 'handlebars' task to specify targets!

    handlebars: {
        all: {
                The output will be formatted as a Common JS module, using a require()
                statement where the argument is the Handlebars path provided in the option.
            files: {
                'pkg/template-compile-test.js': 'template/*.handlebars'
            options: {
                exportCommonJS: 'handlebars'
        some: {
                The output will be set to register two templates under 'myApp.templates' namespace after 
                stripping the templateRoot:
                    * myApp.templates.template1
                    * myApp.templates.template2
            files: {
                'pkg/template-compile-test2.js': [
            options: {
                namespace: 'myApp.templates',
                templateRoot: 'webApp-',
                knownHelpers: ['if', 'each']

The handlebars task has the following options, none of which are required. The defaults are shown here:

        separator: '\n',                    // specify a character to delimit individual compiled files in the output
        namespace: 'Handlebars.templates',    // specify a namespace for templates to be set to register to
        exportAMD: false,                    // export compiled templates as AMD (RequireJS) module
        exportCommonJS: false,                // export as Common JS, provide string path to Handlebars instead of false
        pathToHandlebars: '',                // only relevant if 'exportAMD === true' - provide path to Handlebars
        knownHelpers: [],                    // provide an array of known helpers
        knownOnly: false,                    // compile with known helpers only (requires 'knownHelpers')
        templateRoot: false,                // a value to strip from the beginning of template names
        partial: false                        // EXPERIMENTAL: specify that target templates are partials

Note: You may choose only one 'exportX' option. (Eg. you can't use exportAMD and exportCommonJS on the same task. That would just be straight silly.)


The handlebars task is a multi task, meaning that it will implicitly iterate over all of its targets if no target is specified.
