grunt-contrib-jade

Compile Jade templates

grunt-contrib-jade v1.0.0

Compile Jade templates

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, you may install this plugin with this command:

npm install grunt-contrib-jade --save-dev

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

grunt.loadNpmTasks('grunt-contrib-jade');

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.

Jade task

Run this task with the grunt jade command.

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

Options

pretty

Type: Boolean Default: false

Output indented HTML.

data

Type: Object

Sets the data passed to Jade during template compilation. Any data can be passed to the template (including grunt templates).

This value also might be a function taking source and destination path as arguments and returning a data object. Within the function, this is bound to the file configuration object.

options: {
  data: function(dest, src) {
    return {
      from: src,
      to: dest
    };
  }
}

or you can have options from a required JSON file:

options: {
  data: function(dest, src) {
    // Return an object of data to pass to templates 
    return require('./locals.json');
  }
}

filters

Type: Object

If you want to use filters you have two ways to do it. First you can write your filters inline within your Gruntfile.js or define filters in separate file and export it.

Filters are given a context with the jade instance and local variables: {jade: jade, data: data}, where jade is global jade instance and data is options passed to options.data. You can use this.jade.render() inside your filters to render the content of a block and locals as #{variable} from your data.

Inline filters

Gruntfile.js:

options: {
  filters: {
    some: function(block) {},
    another: function(block) {}
  }
}

Exported filters

Gruntfile.js:

options: {
  filters: require('./filters.js')
}

filters.js:

var jadefilters = module.exports = {};
jadefilters.some = function(block) {};
jadefilters.another = function(block) {};

compileDebug

Type: Boolean Default: true

Add Jade debug instructions to generated JS templates.

client

Type: Boolean Default: false

Compile to JS template functions for client-side use rather than directly to HTML.

Make sure to also include the Jade runtime (only runtime.js) as described in the Jade documentation.

namespace

Type: String, Boolean 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 set to false with amd option set to true, the templates will be returned directly from the AMD wrapper.

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() {
    //...// 
    returns this['[template namespace]'];
});

processName

Type: Function

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.

Example Store all template on the default JST namespace in capital letters.

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

processContent

Type: Function Default: function(content, filename) { return content; };

This option accepts a function that lets you perform additional content processing.

Usage Examples

jade: {
  compile: {
    options: {
      data: {
        debug: false
      }
    },
    files: {
      "path/to/dest.html": ["path/to/templates/*.jade", "another/path/tmpl.jade"]
    }
  }
}

If you want to generate a debug file and a release file from the same template:

jade: {
  debug: {
    options: {
      data: {
        debug: true
      }
    },
    files: {
      "debug.html": "test.jade"
    }
  },
  release: {
    options: {
      data: {
        debug: false
      }
    },
    files: {
      "release.html": "test.jade"
    }
  }
}

If you want to use grunt template in options.data:

jade: {
  debug: {
    options: {
      data: {
        debug: true,
        timestamp: "<%= new Date().getTime() %>"
      }
    },
    files: {
      "debug.html": "test.jade"
    }
  }
}

or you can use grunt helpers (grunt object was exposed at template context):

jade: {
  debug: {
    options: {
      data: {
        debug: true,
        timestamp: "<%= grunt.template.today() %>"
      }
    },
    files: {
      "debug.html": "test.jade"
    }
  }
}
