微信小程序分包

问题描述

小程序开发时，通过npm下载了一些第三方库，然后随着开发的深入，小程序本身页面也比较多，最后导致小程序的体积过大（超过2M），无法正常使用真机预览和调试

这时候就要用到微信小程序的分包功能了

分包过程

分析页面，将一些页面分出去

1.在与pages文件夹同级目录下建立分包文件夹

在这里插入图片描述
本项目可以拆分为4个模块，对应4个包，一个主包，三个分包，主包放首页和登录模块以及一些依赖包，注意删除不必要的依赖包，分析依赖可知，主包中占体积最大的主要是npm下载的依赖包，所以要删除不必要的依赖包，并把主包中的页面拆分到其他包去。

拆包方法

1.在与主包pages同目录下建立分包文件夹，在分包中建立自己的pages文件夹；
2.将主包中同一模块的页面剪切到对应分包的pages目录下；
3.拆分过去之后记得更新之前页面上写的关于页面跳转的路径，否则可能会编译失败；
4.分包中可以自己新建npm，可以有自己的图片文件夹；

具体配置如下：
