For projects created with cli, you can add the parameter-minimize in pacakge.json, for example: "dev:mp-weixin": "cross-env NODE_ENV=development UNI_PLATFORM=mp-weixin vue-cli-service uni-build --watch --minimize"

Mini programs subcontracting vendor or too large
After using subcontracting, you will find a strange problem. The components and js files of the child package will be packaged into the vendor.js file of the main package, which will cause the vendor.js to be too large and cause the main package to exceed 2M.
Open manifest.json-> source view-> mp-weixin node
Add the following code "optimization": { "subPackages": true}
You will find that the js file of the subcontract will no longer be packaged into the vendor.js of the main package, and the pro-test will work.
