A modern frontend development workflow for Symfony apps


This project is deprecated. Use Webpack Encore instead.

Webpack Encore is a simpler way to integrate Webpack into your Symfony application. It wraps Webpack, giving you a clean & powerful API for bundling JavaScript modules, pre-processing CSS & JS and compiling and minifying assets.

There used to be a time where Symfony had no first-class support for a modern frontend development workflow, which was the problem this bundle was trying to solve. With Webpack Encore that is no longer the case so there is no reason for this bundle to continue to exist. Webpack Encore does it better and is the officially recommended way to integrate frontend technologies into Symfony applications.

Symfony comes packaged with Assetic for managing frontend assets like CSS, JavaScript or images. Assetic is great to quickly start a project but, as applications grow, its limitations start to show.

It has thus become more and more common to integrate tools native to frontend development into Symfony projects (bower, gulp, webpack, livereload, etc). However, setting up a seamless frontend development workflow is not easy and developers must repeat themselves every time they start a new project.

There are several tools out there that make it easier to do this but they come with their own limitations and many are wrappers for the native frontend development tools. Developers should be able to use the native tools directly and have them just work within their Symfony projects.

This bundle attempts to be the go-to solution for quickly, easily and cleanly setting up a tailored frontend development workflow in Symfony projects.
