Leverage Bower as your package manager for the front-end assets of your CakePHP application. Define your packages once (jQuery, Bootstrap, and what not?), and let it download everything for you and check for compatibilities among them. No more committing third-party assets to your repository. And also utilizing Gulp.js, the streaming build system, for automating repetitive front-end related tasks like converting LESS to CSS, CoffeeScript to JavaScript, concatenating files, minifying them, etc with just a single command.
