支付宝小程序

小程序基础库: 1.x 2.x
使用框架: Vue 3

复现步骤

pnpm install -g @tarojs/cli
taro init myApp
cd myApp
pnpm install
pnpm run dev:alipay

[email protected] dev:alipay C:\project\myApp
npm run build:alipay -- --watch

[email protected] build:alipay
taro build --type alipay --watch

👽 Taro v4.0.9

Tips:

1. 预览模式生成的文件较大，设置 NODE_ENV 为 production 可以开启压缩。
   Example:
   $ NODE_ENV=production taro build --type alipay --watch
2. 建议开启持久化缓存功能，能有效提升二次编译速度，详情请参考: https://docs.taro.zone/docs/config-detail#cache。

启动 开发者工具-项目目录 C:\project\myApp\dist
Prebundle dependencies:
@tarojs/plugin-framework-vue3/dist/runtime
