> Minify JavaScript with UglifyJS3.
## Installation
Install package with NPM and add it to your development dependencies:
`npm install --save-dev gulp-uglify`
## Usage
```javascript
var gulp = require('gulp');
var uglify = require('gulp-uglify');
var pipeline = require('readable-stream').pipeline;
gulp.task('compress', function () {
return pipeline(
gulp.src('lib/*.js'),
uglify(),
gulp.dest('dist')
);
});
```
To help properly handle error conditions with Node streams, this project
recommends the use of
[`pipeline`](https://nodejs.org/docs/latest/api/stream.html#stream_stream_pipeline_streams_callback),
from [`readable-stream`](https://github.com/nodejs/readable-stream).
## Options
Most of the [minify options](https://github.com/mishoo/UglifyJS2#minify-options) from
the UglifyJS API are supported. There are a few exceptions:
1. The `sourceMap` option must not be set, as it will be automatically configured
based on your Gulp configuration. See the documentation for [Gulp sourcemaps][gulp-sm].
[gulp-sm]: https://github.com/gulp-sourcemaps/gulp-sourcemaps#usage
## Errors
`gulp-uglify` emits an 'error' event if it is unable to minify a specific file.
The GulpUglifyError constructor is exported by this plugin for `instanceof` checks.
It contains the following properties:
- `fileName`: The full file path for the file being minified.
- `cause`: The original UglifyJS error, if available.
Most UglifyJS error messages have the following properties:
- `message` (or `msg`)
- `filename`
- `line`
To see useful error messages, see [Why Use Pipeline?](docs/why-use-pipeline/README.md#why-use-pipeline).
## Using a Different UglifyJS
By default, `gulp-uglify` uses the version of UglifyJS installed as a dependency.
It's possible to configure the use of a different version using the "composer" entry point.
```javascript
var uglifyjs = require('uglify-js'); // can be a git checkout
// or another module (such as `uglify-es` for ES6 support)
var composer = require('gulp-uglify/composer');
var pump = require('pump');
var minify = composer(uglifyjs, console);
gulp.task('compress', function (cb) {
// the same options as described above
var options = {};
pump([
gulp.src('lib/*.js'),
minify(options),
gulp.dest('dist')
],
cb
);
});
```
