SymfonyTwigExtensions

This is a collection of Twig extensions that I use in symfony., _(*1)

Grunt Asset Cache Bust

Extension when using Grunt plugin Cache Bust. See https://github.com/hollandben/grunt-cache-bust, _(*2)

How to install

composer require treeleaf/symfony-twig-extensions

How to use in Symfony

In app/config/services.yml:, _(*3)

services:
  my_app.twig.grunt_cache_bust:
    class: Treeleaf\Twig\Extension\GruntAssetCacheBust
    public: false
    tags:
        - { name: twig.extension }

In a twig template:, _(*4)

<script src="/{{ gruntCacheBust('grunt-cache-bust.json', 'js/app.js') }}"></script>

Grunt

Example Gruntfile.js:, _(*5)

cacheBust: {
    options: {
        assets: ['css/*', 'js/*']
    },
    all: {
        options: {
            expand: true,
            queryString: true,
            jsonOutput: true
        },
        src: ['/js/**/*.js', '/css/**/*.css']
    }
}

This will by default generate a json artefact grunt-cache-bust.json with a mapping of the source file and the hashed file., _(*6)

Example grunt-cache-bust.json:, _(*7)

{
    "js/vendor.js":"js/vendor.js?82f8fc4bb7e495e6",
    "js/app.js":"js/app.js?4df6c65674ecfa3d",
    "css/main.css":"css/main.css?362da3994e41aa48"
}
