# jit-grunt 0.10.0 [![NPM version](https://badge.fury.io/js/jit-grunt.png)](http://badge.fury.io/js/jit-grunt) [![Build Status](https://secure.travis-ci.org/shootaroo/jit-grunt.png?branch=master)](http://travis-ci.org/shootaroo/jit-grunt) [![Built with Grunt](https://cdn.gruntjs.com/builtwith.png)](http://gruntjs.com/)

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


### Before
```js
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
...
Execution Time (2014-01-14 02:52:59 UTC)
loading tasks     5.7s  ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 84%
assemble:compile  1.1s  ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 16%
Total 6.8s
```

umm...


### After
```js
require('jit-grunt')(grunt);
```

```
$ grunt assemble
...
Execution Time (2014-01-14 02:53:34 UTC)
loading tasks     111ms  ▇▇▇▇▇▇▇▇▇ 8%
loading assemble  221ms  ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 16%
assemble:compile   1.1s  ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 77%
Total 1.4s
```

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.

```js
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`

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


### Options

#### cwd

Type: `Strong`
Default: `process.cwd()`

All plugins and tasks are resolved relative to this path.

#### pluginsRoot

Type: `String`  
Default: `'node_modules'`

Root directory of grunt plugins, relative to the working directory.

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

#### customTasksDir

Type: `String`  
Default: `null`

JIT Loading for custom tasks dir (replacement of [grunt.loadTasks]), relative to the working directory..

```js
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`.
