設置分包加載

微信小程序分包限制為：

主包或者單個分包最大為2M

整體小程序所有包最大為8M

為什么需要設置分包？

小程序項目中，有多種角色(公共頁面很少)，設置分包加載方便管理

整個小程序壓縮后代碼大小超過2M，只能將小程序哈芬為不同的包

分包加載，在小程序啟動時，默認下載主包并啟動主包內的頁面，當用戶進入某個分包時，將對應的分包下載并啟動，優化小程序首次啟動的下載時間。

分包設置格式如下實例代碼：

"pages": [

"loading/loading" //主包

],

"subpackages": [

{

"root": "procurement", //分包名稱

"pages": [ //分包內的頁面(路徑)

"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",

"applicationdetails/applicationdetails",

"rejectdetail/rejectdetail",

"apply/apply",

"changeWay/changeWay"

]

},

{

"root": "rural",

"pages": [

"index/index",

"ruralPassCard/ruralPassCard",

"stayconfirm/stayconfirm",

"useable/useable",

"changeGoods/changeGoods",

"loadconfirm/loadconfirm",

"writeLoadInfo/writeLoadInfo"

]

},

{

"root": "station",

"pages": [

},

{
