This NPM config is for copying and compiling assets for a typical Symfony 3 project.

It includes jQuery and FontAwesome. It will compile and minify SCSS, JavaScript and any static assets in the assets directory of your project. To use it, run npm install then npm run dev to compile and start the watchers. Run npm run dev:build to just build without watching.
