Bundling javascript files to watch with Gulp and Nodeman - gulp

Question

I have the start and deploy tasks working the way I want them to but I am trying to figure out how to update public/js/bundle.js when I make a change in app.js so that it can be watched.
Here's what I got so far:
var gulp = require('gulp');
var streamify = require('gulp-streamify');
var uglify = require('gulp-uglify');
var transform = require('vinyl-source-stream');
var browserify = require('browserify');
var rename = require('gulp-rename');
var nodemon = require('gulp-nodemon');
var ios = browserify({
entries:['app.js']
});
const bundle = () => {
process.env.NODE_ENV = 'production';
ios.require('./app-ios.js', {expose:'appalias'})
.bundle()
.pipe(transform('bundle-ios.js'))
.pipe(gulp.dest('./public/js'))
.pipe(streamify(uglify()))
.pipe(rename('bundle-ios.min.js'))
.pipe(gulp.dest('./public/js'));
return ios;
}
const start = () => {
return nodemon({
script: 'server.js',
watch: ['server.js', 'public/js/*', 'public/index.html', 'public/css/*'],
ext: 'js html css',
env: { 'NODE_ENV': 'development' },
});
}
// Start local server and watch bundles.
gulp.task('start', start);
// Build minified versions for prod.
gulp.task('deploy', bundle);

The fix was to watch all the individual javascript component and model files and add a compile task to the start task.
// Bundle and minify for development, use development version of libraries.
const compile = () => {
process.env.NODE_ENV = 'development';
const bundleAndroidDev = ios.require('./app-ios.js', {expose:'appalias'})
.bundle()
.pipe(transform('bundle-ios.js'))
.pipe(gulp.dest('./public/js'));
return bundleIosDev;
}
// Start local server and watch for changes in compiled bundles.
const start = () => {
return nodemon({
script: 'server.js',
watch: ['server.js', 'apps/appName/components/*', 'apps/appName/models/*', 'public/index.html', 'public/css/*'],
ext: 'js html css',
tasks: ['compile'],
env: { 'NODE_ENV': 'development' }
});
}
// Compile bundle's on save.
gulp.task('compile', compile);
