微信小程序分包加载设置

设置分包加载

微信小程序分包限制为：

• 主包或者单个分包最大为2M
• 整体小程序所有包最大为8M

为什么需要设置分包？

1. 小程序项目中，有多种角色（公共页面很少），设置分包加载方便管理
2. 整个小程序压缩后代码大小超过2M，只能将小程序哈芬为不同的包
3. 分包加载，在小程序启动时，默认下载主包并启动主包内的页面，当用户进入某个分包时，将对应的分包下载并启动，优化小程序首次启动的下载时间。

分包设置格式如下实例代码：

  "pages": [
    "loading/loading"      //主包
  ],
  "subpackages": [
    {
      "root": "procurement",  //分包名称
      "pages": [   //分包内的页面（路径）
        "index/index",
        "myPassCard/myPassCard",
        "apply/apply",

      ]
    },
    {
