Compile JavaScript files into a single file

ionic-v1
1

The project grows up. There are a lot of code lines. I am going to divide it into small files and to compile to a single file injecting it in to the application. I did before. Yes I’ve found gulp file. Help me to turn it right. Thank you.

gulp.task('compile_app', function () {
  gulp.src(['src/**/*.js'])
    .pipe(plumber())
    .pipe(sourcemaps.init())
    .pipe(concat('app.js'))
    .pipe(ngAnnotate())
    //.pipe(uglify())
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('.'));
});

gulp.task('watch', function () {
  watch('src/**/*.js', function (files, cb) {
    gulp.start('compile_app', cb);
  })
  .pipe(plumber());
});
