I would personally recommend this awesome ES6 course by Wes Bos.


$ npm install --save-dev gulp-autoprefixer
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'))
);

See the Autoprefixer options.

Use gulp-sourcemaps like this:

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'))
);

You might want to use Autoprefixer as a PostCSS plugin if you use other PostCSS plugins in your build process.
