My Gulp config for typical symfony 2/3 project. Includes BrowserSync with CSS Injection. Based on: https://knpuniversity.com/screencast/gulp

Shows following additional features:

1. Adds ability to execute console commands in order with Pipeline class; (If some command fails, command execution stops)

2. Adds browserSync Gulp integration with Css injection support;

3. Modifies AssetExtension class - now css/js assets are versioned only in prod environment, because dynamic name change will force browserSync to perform full page reload instead of Css injection on sass/css file changes;

4. Extends FosJsRoutingBundle to override initialize method in dump command and inject target arg to InputInterface object. (We want apply versioning to 'fos_js_routes.js' file as well on production environment)
