mpvue 同时开发和打包成H5和微信小程序

一、mpvue只打包小程序

注意（遇到的坑）：

• url 路由参数通过 this.root.root.mp.query获取，并且在page onLoad 时候传递的 options，即mounted生命函数中能获取

• 之前的this.router.push改成小程序支持的wx.navigateTo(url)，this.router.push改成小程序支持的wx.navigateTo(url)，this.router.replace 改成 wx.reLaunch({ url })，其他相关的api 均改成对应的微信小程序的api

• 引用图片路径时，微信小程序中不支持在template中使用require请求图片资源，静态请求src可以使用../../../static/img/或者 /static/img/引用根目录图片，动态引用src 时，使用 /static/img/，在同时能兼容H5的时候，可使用变量+局部路径来实现，如小程序能编译 /static/img/，而H5能编译 static/img/

• vuex 的使用，官方给的demo是pages 文件每个page页面各一个store.js储存数据；可以直接挂到Vue原型上，在入口文件main.js中：
  import store from ‘./store’
  Vue.prototype.$store = store

• package.json文件里面：红线里面的去掉

  然后修改一下配置：

//config文件下面的index.js
build: {
    index: path.resolve(__dirname, `../dist/${fileExt.platform}/index.html`),
    assetsRoot: path.resolve(__dirname, `../dist/${fileExt.platform}`),
.....
}

改成：

build: {
    index: path.resolve(__dirname, '../dist/index.html'),
    assetsRoot: path.resolve(__dirname, '../dist'),
.....
}

//build文件下面的webpack.dev.conf.js
plugins: [
    new ExtractTextPlugin({
      filename: utils.assetsPath(`[name].${config.dev.fileExt.style}`)
    }),
.....
]

改成：

new ExtractTextPlugin({
      filename: utils.assetsPath('css/[name].wxss')
    }),

//project.config.json

改成：
"miniprogramRoot": "dist/",

小程序正常开发打包，使用微信开发者工具调试 源码： github https://github.com/Aimee1608/mpsudoku469

二、添加打包成H5配置

安装

安装对应的module vue 、vuex、vue-loader、vue-style-loader、vue-template-compiler、webpack-dev-server等
具体配置文件如下：

}

配置：

• 在原有的基础上添加webpack 开发打包buildH5 和 configH5配置文件 ,以及对应的路由配置文件router ，AppH5.vue入口vue 文件，mainH5.js 编译入口文件，以及对H5和wx 分别封装的方法及api
  在configH5中配置build 输出的文件目录为distH5 :
  index: path.resolve(__dirname, ‘../distH5/index.html’)
  assetsRoot: path.resolve(__dirname, ‘../distH5’)

• 在package.json 文件中配置编译和打包文件的命令执行语句
  “devH5”: “webpack-dev-server –inline –progress –config buildH5/webpack.devH5.conf.js”,
  “all”: “npm run dev && npm run devH5”,
  “buildH5”: “node buildH5/build.js”

注意配置文件：
.postcssrc.js 此条为编译微信的时候需用配置 “postcss-mpvue-wxss”: {}，转化成wxss有特别棒的效果，可以优化css的样式，编译成wxss可识别的样式代码，但启动H5时要把“postcss-mpvue-wxss”: {}注释掉

打包成H5的配置内容

• AppH5.vue 添加入口设置

<template>
  <div id="app">
    <router-view></router-view>
  </div>
</template>

<script>
export default {
    name: 'App'
}
</script>

• main.js 和 mainH5.js 通过Vue.mixin分别配置微信小程序和H5的相同功能但不同api 的方法及变量
  main.js 如下图：

  mainH5.js 如下图
