6. Complete Gulp Workflow

To bring this all together, we need to get Gulp to watch our index.jsx file and call our jsx task whenever the file is touched. Then we’ll be able to run Gulp once and freely edit the index.jsx file and have the changes pick up automatically. First you’ll need to install Gulp Watch:

  1. npm install gulp-watch --save-dev
  2. Then make the following changes to gulpfile.js:
var gulp = require('gulp')
  , gulpReact = require('gulp-react')
  , gulpNodemon = require('gulp-nodemon')
  , gulpWatch = require('gulp-watch')

gulp.task('watch-jsx', ['jsx'], function() {
  gulpWatch('**/*.jsx', { ignored: 'lib/' }, function() {

gulp.task('jsx', function() {
  return gulp.src('**/*.jsx')

gulp.task('node', ['watch-jsx'], function() {
    script: 'lib/index.js',
    ignore: ['gulpfile.js'],
    ext: 'js jsx'

gulp.task('default', function() {

Next, run Gulp to see that it starts the server after transforming index.jsx into lib/index.js. Then edit index.jsx to have the following content. After saving the file, you’ll see that everything automatically reruns.

var http = require('http')
var React = require('react')

http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'})
          <title>Hello World</title>
          index.jsx, automatically processed
          through gulp and gulp-react, with
          node automatically restarted
          through gulp-nodemon!
console.log('Server running at http://localhost:1337/')
