## Usage
|
|
|
|
```js
|
|
const gulp = require('gulp');
|
|
const autoprefixer = require('gulp-autoprefixer');
|
|
|
|
gulp.task('default', () =>
|
|
gulp.src('src/app.css')
|
|
.pipe(autoprefixer({
|
|
browsers: ['last 2 versions'],
|
|
cascade: false
|
|
}))
|
|
.pipe(gulp.dest('dist'))
|
|
);
|
|
```
|
|
|
|
|
|
## API
|
|
|
|
### autoprefixer([options])
|
|
|
|
#### options
|
|
|
|
Type: `Object`
|
|
|
|
See the Autoprefixer [options](https://github.com/postcss/autoprefixer#options).
|
|
|
|
|
|
## Source Maps
|
|
|
|
Use [gulp-sourcemaps](https://github.com/gulp-sourcemaps/gulp-sourcemaps) like this:
|
|
|
|
```js
|
|
const gulp = require('gulp');
|
|
const sourcemaps = require('gulp-sourcemaps');
|
|
const autoprefixer = require('gulp-autoprefixer');
|
|
const concat = require('gulp-concat');
|
|
|
|
gulp.task('default', () =>
|
|
gulp.src('src/**/*.css')
|
|
.pipe(sourcemaps.init())
|
|
.pipe(autoprefixer())
|
|
.pipe(concat('all.css'))
|
|
.pipe(sourcemaps.write('.'))
|
|
.pipe(gulp.dest('dist'))
|
|
);
|
|
```
|
|
|
|
|
|
## Tip
|
|
|
|
If you use other PostCSS based tools, like `cssnano`, you may want to run them together using [`gulp-postcss`](https://github.com/postcss/autoprefixer#gulp) instead of `gulp-autoprefixer`. It will be faster, as the CSS is parsed only once for all PostCSS based tools, including Autoprefixer.
