jit-grunt 0.9.1

A JIT(Just In Time) plugin loader for Grunt.
Load time of Grunt does not slow down even if there are many plugins.

Before

grunt.loadNpmTasks('assemble');
grunt.loadNpmTasks('grunt-contrib-clean');
grunt.loadNpmTasks('grunt-contrib-connect');
grunt.loadNpmTasks('grunt-contrib-copy');
grunt.loadNpmTasks('grunt-contrib-csslint');
grunt.loadNpmTasks('grunt-contrib-less');
grunt.loadNpmTasks('grunt-contrib-jshint');
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-newer');
grunt.loadNpmTasks('grunt-wget');
...

$ grunt assemble
...

require('jit-grunt')(grunt);

$ grunt assemble

Have a pleasant Grunt life!

Install

npm install jit-grunt --save-dev

Usage

Removes grunt.loadNpmTasks, then add the require('jit-grunt')(grunt) instead. Only it.

module.exports = function (grunt) {
  require('jit-grunt')(grunt);

  grunt.initConfig({
    ...
  });

  grunt.registerTask('default', [...]);
}

Will automatically search for the plugin from the task name. Search in the following order:

1. node_modules/grunt-contrib-task-name
2. node_modules/grunt-task-name
3. node_modules/task-name

clean           -> node_modules/grunt-contrib-clean
wget            -> node_modules/grunt-wget
mochaTest       -> node_modules/grunt-mocha-test
mocha_phantomjs -> node_modules/grunt-mocha-phantomjs
assemble        -> node_modules/assemble

Static mappings

Second parameter is static mappings.
It is used when there is a plugin that can not be resolved in the automatic mapping.

taskname: grunt-plugin-name

require('jit-grunt')(grunt, {
  sprite: 'grunt-spritesmith',
  foo: '@abc/grunt-foo',        // for private modules.
  bar: 'custom/bar.js'          // for custom tasks.
});

Options

pluginsRoot

Type: String
Default: 'node_modules'

Root directory of grunt plugins.

require('jit-grunt')(grunt)({
  pluginsRoot: 'other/dir'
});

customTasksDir

Type: String
Default: null

JIT Loading for custom tasks dir (replacement of grunt.loadTasks).

require('jit-grunt')(grunt)({
  customTasksDir: 'custom/dir'
});

Search in the following order:

1. custom/dir/taskname.js
2. custom/dir/taskname.coffee

loadTasks

Alias to customTasksDir.
