Single SPA

提示
  • 建议使用单个版本框架
  • 适用于跨框架 - 如果不 跨框架，建议自行封装一个简单的挂载逻辑
Topic应用/applicationparcel工具/utility
路由✅无路由无路由

渲染 UI✅✅❌
生命周期single-spa 管理自行管理❌
使用场景核心构建组件多个框架的时候需要公共逻辑

create-single-spa​

# http://localhost:9000
# 默认 importmap 是在 html 中
# 开启 importmap 开发工具
# localStorage.setItem("devtools", true);
yarn create single-spa --framework react --moduleType root-config --dir root

yarn create single-spa --framework react --dir dash
# localhost:8500
# http://single-spa-playground.org/playground/instant-test?name=@wener-dash/spa&url=8500
# 默认位置 http://localhost:8500/<OrgName>-<ProjectName>.js
# 例如 http://localhost:8500/wener-spa-dash.js
yarn start --port 8500


yarn create single-spa --framework react --moduleType util-module --dir utils \
  --packageManager yarn --typescript

# react + ts 使用的配置
# yarn add --dev webpack-config-single-spa-react-ts webpack-merge
