React.js Getting Started Gulp Example

gulpfile.babel.js

var gulp = require('gulp')
var browserify = require('browserify')
var babelify = require('babelify')
var source = require('vinyl-source-stream')

gulp.task('build', () => {
  // our js lives in main.js, so its our source
  var b = browserify('main.js')
  b.transform(babelify, {presets: ['es2015', 'react']})
  
  // the output will be called bundle.js and it will be put in the public folder
  return b.bundle().pipe(source('bundle.js')).pipe(gulp.dest('public'))
})
