### Additional Info:
This one is a beast. Write your React JSX code, in ES6, compiled by Browserify and auto-reload all devices
when the compilation is complete.
### Preview of `gulpfile.js`:
```js
var gulp = require('gulp');
var gutil = require('gulp-util');
var source = require('vinyl-source-stream');
var babelify = require('babelify');
var watchify = require('watchify');
var exorcist = require('exorcist');
var browserify = require('browserify');
var browserSync = require('browser-sync').create();
// Watchify args contains necessary cache options to achieve fast incremental bundles.
// See watchify readme for details. Adding debug true for source-map generation.
watchify.args.debug = true;
// Input file.
var bundler = watchify(browserify('./app/js/app.js', watchify.args));
// Babel transform
bundler.transform(babelify.configure({
sourceMapRelative: 'app/js'
}));
// On updates recompile
bundler.on('update', bundle);
function bundle() {
gutil.log('Compiling JS...');
return bundler.bundle()
.on('error', function (err) {
gutil.log(err.message);
browserSync.notify("Browserify Error!");
this.emit("end");
})
.pipe(exorcist('app/js/dist/bundle.js.map'))
.pipe(source('bundle.js'))
.pipe(gulp.dest('./app/js/dist'))
.pipe(browserSync.stream({once: true}));
}
/**
* Gulp task alias
*/
gulp.task('bundle', function () {
return bundle();
});
/**
* First bundle, then serve from the ./app directory
*/
gulp.task('default', ['bundle'], function () {
browserSync.init({
server: "./app"
});
});
```
