**NOTE: `grunt-defs` is no longer developed similarly to the underlying [defs](https://www.npmjs.com/package/defs) package. Use Babel or Typescript with their Grunt plugins; they do so much more.**
## Getting Started
This plugin requires Grunt.
If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to create a [Gruntfile](http://gruntjs.com/sample-gruntfile) as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
```shell
npm install grunt-defs --save-dev
```
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
```js
grunt.loadNpmTasks('grunt-defs');
```
## The "defs" task
### Overview
In your project's Gruntfile, add a section named `defs` to the data object passed into `grunt.initConfig()`.
```js
grunt.initConfig({
defs: {
options: {
// Task-specific options go here.
},
your_target: {
// Target-specific file lists and/or options go here.
},
},
})
```
#### Options
The `defs` task accepts a couple of options:
```js
{
// Here one can set `defs` options; see: https://npmjs.org/package/defs
defsOptions: {
disallowDuplicated: true,
disallowUnknownReferences: false,
disallowVars: true,
},
// Instead of providing `defsOptions` manually, one can provide a URL to the `defs-config.json`
// configuration file; see: https://npmjs.org/package/defs
defsConfigUrl: string,
}
```
### Usage Examples
```js
grunt.initConfig({
defs: {
options: {
defsConfigURL: 'defs-config.json',
},
app1: {
files: {
'a.js': ['a.js'],
'c.js': ['b.js'],
'f.js': ['d.js', 'e.js'],
},
},
app2: {
files: [
{
expand: true,
src: ['f.js'],
ext: '.defs.js', // Dest filepaths will have this extension.
extDot: 'last', // Extensions in filenames begin after the last dot
},
],
},
app3: {
files: [
{
expand: true,
src: ['g.js'],
rename: function (dest, src) { return src + '-defs'; },
},
],
},
},
});
grunt.loadNpmTasks('grunt-defs');
```
After executing `grunt defs`, you'll get file `a.js` transformed and saved under the same name, file `b.js`
transformed and saved as `c.js` and files `d.js` and `e.js` concatenated, transformed and saved as `f.js`.
A transformed version of the `f.js` file will be saved as `f.defs.js` and a transformed version of the `g.js` file will be saved as `g.js-defs`.
## Supported Node.js versions
This project aims to support all Node.js LTS versions in the "active" phase (see [LTS README](https://github.com/nodejs/LTS/blob/master/README.md) for more details) as well as the latest stable Node.js.
Because of the popularity of this package and Node.js 0.10, this version is temporarily supported as well.
## Contributing
In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using [Grunt](http://gruntjs.com/).
