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",
        "usable/usable",
        "unauthorized/unauthorized",
        "authdriver/authdriver",
        "applicationdetails/applicationdetails",
        "rejectdetail/rejectdetail",
        "createInvitecode/createInvitecode"
      ]
    },
    {
      "root": "driver",
      "pages": [
        "index/index",
        "driverPassCard/driverPassCard",
        "useable/useable",
        "unauthorized/unauthorized",

      ]
    },

        "index/index",
        "carList/carList",
        "scan/scan",
