grunt-contrib-jst

Precompile Underscore templates to JST file.

Getting Started

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, install this plugin with this command:

npm install grunt-contrib-jst --save-dev

Jst task

Run this task with the grunt jst command.

This task is a [multi task][] so any targets, files and options should be specified according to the [multi task][] documentation. [multi task]: https://github.com/gruntjs/grunt/wiki/Configuring-tasks

Version 0.4.x of this plugin is compatible with Grunt 0.4.x. Version 0.3.x of this plugin is compatible with Grunt 0.3.x.

This plugin uses the Lo-Dash library to generate JavaScript template functions. Some developers generate template functions dynamically during development. If you are doing so, please be aware that the functions generated by this plugin may differ from those created at run-time. For instance, the Underscore.js library will throw an exception if templates reference undefined top-level values, while Lo-Dash will silently insert the empty string in their place.

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 asssigned. Use dot notation (e.g. App.Templates) for nested namespaces.

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(filename) {
    return filename.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
}

amdWrapper

Type: boolean Default: false

With Require.js and a pre-compiled template.js you want the templates to be wrapped in a define. This will wrap the output in:

define(function() {
  //Templates
  return this["NAMESPACE"];
});

Example:

options: {
  amdWrapper: 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"]
    }
  }
}
