Minify (not transpile) ES2015 code with Gulp

How to minify ES2015 code without transpiling it to ES5? The popular gulp-minify and gulp-uglify modules do not work with simply minifying ES2015 code.

Solution

  • It is now possible to minify ES2015 without transpiling the code. babel minify (previously babili) is a babel preset that does that.

    To install do:

    npm install --save-dev babel-preset-minify

    To use it with gulp you do:

    var gulp = require('gulp')
var babel = require('gulp-babel')
gulp.task('default', () => {
  return gulp.src('src/app.js')
  .pipe(babel({presets: ['minify']}))
  .pipe(gulp.dest('dist'))
})
