grunt-contrib-jst v0.7.1

Precompile Underscore templates to JST file.

Getting Started

A respin to add support for things I couldn't wait for (CJS, remove dependency to bring underscore with).

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-jst-redux --save-dev

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

grunt.loadNpmTasks('grunt-jst-redux');

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade, but in case you can't please use v0.3.1.

Jst task

Run this task with the grunt jst command.

Task targets, files and options may be specified according to the grunt Configuring tasks guide.

Options

separator

Type: String Default: linefeed + linefeed

Concatenated files will be joined on this string.

namespace

Type: String Default: 'JST'

The namespace in which the precompiled templates will be assigned. Use dot notation (e.g. App.Templates) for nested namespaces or false for no namespace wrapping. When false with amd option set true, templates will be returned directly from the AMD wrapper.

processName

Type: function Default: null

This option accepts a function which takes one argument (the template filepath) and returns a string which will be used as the key for the precompiled template object. The example below stores all templates on the default JST namespace in capital letters.

options: {
  processName: function(filepath) {
    return filepath.toUpperCase();
  }
}

templateSettings

Type: Object Default: null

The settings passed to underscore when compiling templates.

jst: {
  compile: {
    options: {
      templateSettings: {
        interpolate : /\{\{(.+?)\}\}/g
      }
    },
    files: {
      "path/to/compiled/templates.js": ["path/to/source/**/*.html"]
    }
  }
}

prettify

Type: boolean Default: false

When doing a quick once-over of your compiled template file, it's nice to see an easy-to-read format that has one line per template. This will accomplish that.

options: {
  prettify: true
}

amd

Type: boolean Default: false

Wraps the output file with an AMD define function and returns the compiled template namespace unless namespace has been explicitly set to false in which case the template function will be returned directly.

define(function() {
    //...//
    return this['[template namespace]'];
});

Example:

options: {
  amd: true
}

processContent

Type: function

This option accepts a function which takes one argument (the file content) and returns a string which will be used as template string. The example below strips whitespace characters from the beginning and the end of each line.

options: {
  processContent: function(src) {
    return src.replace(/(^\s+|\s+$)/gm, '');
  }
}

Usage Examples

jst: {
  compile: {
    options: {
      templateSettings: {
        interpolate : /\{\{(.+?)\}\}/g
      }
    },
    files: {
      "path/to/compiled/templates.js": ["path/to/source/**/*.html"]
    }
  }
}

Note that the interpolate: /\{\{(.+?)\}\}/g setting above is simply an example of overwriting lodash's default interpolation. If you want to parse templates with the default _.template behavior (i.e. using <div><%= this.id %></div>), there's no need to overwrite templateSettings.interpolate.
