配套学习博客：Vue.js 技术揭秘。
为了便于调试，我们需要如下操作：
首先，进入Vue的项目根目录，通过以下命令安装相关依赖（如果安装失败了则使用cnpm安装模块）：
$ npm install
其次，给 package.json 文件中的 dev 脚本中添加参数 --sourcemap（便于后续调试，内容如下），然后删除dist文件夹，重新输入npm run dev进行打包（打包的路径不能包含中文，否则可能打包失败）：
{
scripts: {
"dev": "rollup -w -c scripts/config.js --sourcemap --environment TARGET:web-full-dev",
}
}对使用rollup进行打包的 dev 脚本中参数解释如下：
-w：监听文件的变化，文件变化自动重新打包-c：执行rollup打包时遵循的配置内容--environment：打包后的Vue的使用版本
使用以上命令打包生成的目录结构如下：
然后，我们打开 examples/grid 文件夹（以此为例），更改 index.html 导入的Vue文件，将 vue.min.js 更改为上边打包生成的 vue.js，使用 http-server 或者 Live Server 打开该示例文件，结果如下：
最后，打开 Chrome 的调试工具中的 source面板（配置了 --sourcemap 才能看到如下的src文件夹），我们可以看到：
按F11，就可以进入Vue内部源码了，而不是 dist 文件夹中打包后的代码：
至此，调试准备工作完成！
另外，为了分析 Vue 的编译过程，这里选择 runtime + compiler版本（即TARGET为web-full-dev）的Vue的入口文件为：src/platforms/web/entry-runtime-with-compiler.js 作为分析入口文件。
还有就是，当我们在项目开发中执行 import Vue from 'vue' 的时候，就是从这个入口开始去执行代码来初始化 Vue 的。
针对简单的示例，那么直接在 examples/00-vue-analysis 目录中，通过一个个 .html 文件打断点进行调试。
对于涉及 sfc 的调试，则参看 examples/vue-cli-vue2.6-project 工程进行调试，对应于不同的调试需求，选择用打 tag 的方式记录不同的示例。

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. It is designed from the ground up to be incrementally adoptable, and can easily scale between a library and a framework depending on different use cases. It consists of an approachable core library that focuses on the view layer only, and an ecosystem of supporting libraries that helps you tackle complexity in large Single-Page Applications.
Vue.js supports all browsers that are ES5-compliant (IE8 and below are not supported).
| Project | Status | Description |

| vuex |  |
