options
Type: object
See the Autoprefixer options.
Source Maps
Use gulp-sourcemaps like this:
const gulp = require('gulp');
const sourcemaps = require('gulp-sourcemaps');
const autoprefixer = require('gulp-autoprefixer');
const concat = require('gulp-concat');
exports.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 instead of gulp-autoprefixer. It will be faster, as the CSS is parsed only once for all PostCSS based tools, including Autoprefixer.
