Grunt usemin: verkettete JavaScript-Datei nicht erstellt

Question

Ich verwende die usemin Aufgabe in meinem Yeoman-Generator. Im HTML scheint es gut zu funktionieren, da die separaten JavaScript-Dateien durch einen Link zu einer einzelnen Datei ersetzt werden. Die Datei, auf die verwiesen wird, wurde jedoch nicht erstellt. Vermisse ich eine Einstellung?

Gruntfile.js

'use strict'; 

module.exports = function (grunt) { 
    // load all grunt tasks 
    require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks); 

    // configurable paths 
    var yeomanConfig = { 
     app: 'app', 
     dev: 'dev',

    grunt.initConfig({

Answer 1

Sie werden concat und min Aufgaben nach usemin benötigen. UseMin ändert nur die Konfiguration für concat.

In einem meiner Projekte habe ich folgendes:

<!-- build:js /js/scripts.min.js --> 
    <script src="/assets/javascript/source/index.js"></script> 
    <script src="/assets/javascript/source/flipper.js"></script> 
    <script src="/assets/javascript/source/utils.js"></script> 
    <script src="/assets/javascript/source/overlay.js"></script> 
    <script src="/assets/javascript/source/views.js"></script> 
    <script src="/assets/javascript/source/rotator.js"></script> 
    <script src="/assets/javascript/source/promos.js"></script> 
    <!-- endbuild --> 

und meine Grunt Aufgabe ist dies:

grunt.registerTask('produce', [ 
    'useminPrepare', 
    'concat', 
    'uglify', 
    'cssmin', 
    'usemin' 
]); 

Sie einfach concat & haben müssen, um Ihr Projekt installiert verunstalten, gibt es keine Konfiguration erforderlich, da UseMin das handhabt.
