Loading javascript files from the vendors in CakePHP 3

Question

My problem is how to load .js files from the vendors folder in CakePHP 3.0. I have included twitter bootstrap via composer. The .js file is located in /vendor/twbs/bootstrap

I've found a solution! If I'm using composer why not to use it for this too, right? :)

In composer.json:

"scripts": {
    "post-install-cmd": "App\\Console\\Installer::postInstall",
    "post-update-cmd": "App\\Console\\Installer::postUpdate"
}

In src/Console/Installer.php:

public static function postUpdate(Event $event) {
    $io = $event->getIO();

    $rootDir = dirname(dirname(__DIR__));

    static::copyTwitterBootstrapFiles($rootDir, $io);
}

public static function copyTwitterBootstrapFiles($dir, $io) {

    $bootstrapJsSource = $dir . '/vendor/twbs/bootstrap-sass/assets/javascripts/bootstrap.js';
    $bootstrapJsDestination = $dir . '/webroot/js/bootstrap.js';

    if (file_exists($bootstrapJsSource)) {
        copy($bootstrapJsSource, $bootstrapJsDestination);
        $io->write('Copied `bootstrap.js` file');
    }

}

And finally if you are using git add webroot/bootstrap.js to .gitignore. The postUpdate runs after every composer update command, so if you want to run the script after every actual package update just use post-package-update instead of post-update-cmd.
