Voir la source de Symfony 3 - grunt export bundles

<pre>
la commande principale étant : php bin/console assets:install 

1 - générer les assets à chaque modification de fichiers dans :
src/AppBundle/Resources/public

Se servir de grunt (nodes_modules) dans le répertoire de l'application.

1 - Installer les modules
npm install grunt-shell --save-dev  (pour exécuter la commande  php bin/console assets:install 
npm install grunt-contrib-watch --save-dev (pour surviller le repertoire des assets)

2 - mettre en place le script suivant
module.exports = function(grunt) {

    grunt.initConfig({
        baseURL: "src/AppBundle/Resources/public",

        shell: {
            clearCache: {
                options: {
                    stdout: true
                },
                command: 'php bin/console cache:clear'
            },
            assetsInstall: {
                options: {
                    stdout: true
                },
                command: 'php bin/console assets:install'
            }
        },
        watch: {
            options: {
                dateFormat: function(time) {
                    grunt.log.writeln("The watch finished in " + time + "ms at" + (new Date()).toString());
                    grunt.log.writeln("Waiting for more changes...");
                }
            },
            branchChanged: { // clear cache if the branch is changed
                files: '.git/HEAD',
                tasks: ['shell:clearCache'],
                options: {
                    spawn: true
                }
            },
            scripts: {
                files: ['<%= baseURL %>/**/*.js',
                    '<%= baseURL %>/**/*.css',
                    '<%= baseURL %>/**/*.sass',
                    '<%= baseURL %>/**/*.scss',
                    '<%= baseURL %>/**/*.less',
                    '<%= baseURL %>/**/*.png',
                    '<%= baseURL %>/**/*.svg',
                    '<%= baseURL %>/**/*.gif',
                    '<%= baseURL %>/**/*.jpg',
                    '<%= baseURL %>/**/*.jpeg',
                    '<%= baseURL %>/**/*.map',
                    '<%= baseURL %>/**/*.twig'],
                tasks: ['shell:assetsInstall'],
                options: {
                    interrupt: true
                }
            }
        }
    });

    grunt.loadNpmTasks("grunt-contrib-watch");
    grunt.loadNpmTasks("grunt-shell");
    grunt.registerTask("default", ['shell:assetsInstall']);

    grunt.registerTask("assets install", "A task to install assets.", function() {
        grunt.task.run("shell:assetsInstall");
    });

    grunt.registerTask("all", "A task to dump all assets and clear cache.", function() {
        grunt.task.run("shell:clearCache");
        grunt.task.run("shell:assetsInstall");
    });

    grunt.registerTask("setDir", "A task to set the web dir of the project.", function() {
        grunt.config.set("dir", "web/bundles/app");
        grunt.log.writeln("DIR: " + grunt.config.get("dir"));
        grunt.log.writeln("BASE_URL: " + grunt.config.get("baseURL"));
    });

    console.info("BASE_URL: " + grunt.config.get("watch").scripts.files[0]);
    grunt.task.run(['setDir']);
};

3 - ouvrir une console et se placer dans l'application
