Answer 1

Try the following:

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

gulp.task(
    browserify('js/main.js')
    .bundle()
    .pipe(source('bundle.js'))
    .pipe(uglify())
    .pipe(gulp.dest('./'));
});

gulp.task('watch', function () {
    gulp.watch('js/*.js', ['js']);
})
