通常vue都是搭配webpack+vue-cli使用的

如果不在nodejs环境下开发web应用呢?

这里提出一个解决方案:

1、加载requirejs,并且指定main函数

<script data-main="js/main" src="https://cdn.bootcss.com/require.js/2.3.5/require.min.js"></script>

2、定义main函数

require.config({
    paths: {
        "text": 'https://cdn.bootcss.com/require-text/2.0.12/text.min',
        'vueLoader': 'componentLoader',
        'article': '../components/article',
        'color': '../components/dialog/color',
        'util': './common/util',
        'app': './workspace/vueSet',
    },
    waitSeconds: 3
});


require(['vueLoader', 'componentConfig', 'app'], (CptLoader, commCpt, app) => {
    CptLoader.config(commCpt,()=>{
        setTimeout(()=>{
            app.$mount(app.$el);
        })
    })
});

可以注意到,这提供了一个CptLoader

3、组件loader源码如下所示:

/**
 * 组件加载器
 */

//缓存Vue对象
var pool = {};


define([], () => {
    //根据path获取名称
    function cal(path) {
        let r = path.split('/');
        return r[r.length - 1];
    }

    return {
        /**
         * 加载全局配置单
         * @param configs
         */
        config(configs, res){
            return new Promise(() => {
                configs.forEach((path, index) => {
                    require(['text!../components/' + path + '.html', '../components/' + path], (html, js) => {
                        let v = {
                            template: html,
                            mixins: [
                                js
                            ]
                        };
                        pool[path] = v;
                        let name = cal(path);
                        Vue.component('v-' + name, pool[path]);
                        if (res && index == configs.length - 1)
                            res();
                    });
                });
            });
        },
        /**
         * 加载指定path的组件,返回Promise
         * @param path
         * @returns {function(*)}
         */
        load(path){
            return res => {
                let t;
                if (t = pool[path])
                    res(t);
                else
                    require(['text!../components/' + path + '.html', '../components/' + path], (html, js) => {
                        let v = {
                            template: html,
                            mixins: [
                                js
                            ]
                        };
                        pool[path] = v;
                        res(v);
                    });
            }
        }
    };
});
