WEEX（2）初始化幹了什麼

執行

weex init testweex1

結構如下：

執行

npm install

結構如下：多了個node_modules文件夾

直接執行

npm run serve

結構如下：多了個config.js

這時候訪問http://localhost:8080/index.html界面是空的，爲什麼能因爲沒有執行：

npm run dev

執行以後，結構如下：多了個dist文件夾

接下來就深入探討下這幾個命令幹了什麼：
先看看npm run dev 在搞什麼事情，打開package.json

{

  "description": "testweex",

  "private": true,
  "main": "index.js",

    "debug": "weex-devtool"
  },
  "dependencies": {
    "vue": "^2.1.8",
    "vue-router": "^2.1.1",

    "vuex-router-sync": "^4.0.1",
    "weex-vue-render": "^0.1.4"
  },
  "devDependencies": {
    "babel-core": "^6.20.0",
    "babel-loader": "^6.2.9",
    "babel-preset-es2015": "^6.18.0",
    "css-loader": "^0.26.1",
    "ip": "^1.1.4",
    "serve": "^1.4.0",
    "vue-loader": "^10.0.2",
    "vue-template-compiler": "^2.1.8",
    "webpack": "^1.14.0",
    "weex-devtool": "^0.2.64",
    "weex-loader": "^0.4.1",
    "weex-vue-loader": "^0.2.5"
  }
}

npm run dev 幹了webpack --watch ，webpack實際上是執行了默認的webpack.config.js配置文件。
webpack.config.js 引入webpack和weex-loader，entry屬性是表示入口文件，output表示輸出文件，默認輸出到dist文件夾。
