现象:配置 approuter prefetch 后,实际未预加载微应用 router 相关资源
原因定位:AppRouter 内部在 construct 时,解析 React.children,进行微应用的 prefetch,这要求在 AppRouter 在构建时就需要提供所有微应用的 child。
修复方式:修改 @ice/plugin-icestark 插件中,对 AppRouter 的渲染方式,传入 apps,在 AppRouter 中,判定 apps 变化,做 prefetch。


构造方法时 prefetch

componentWillReceiveProps(nextProps: Readonly<AppRouterProps>, nextContext: any): void {
if (nextProps.apps !== this.props.apps) {
this.tryPrefetch(nextProps);

在 componentWillReceiveProps 阶段会存在多次执行的情况,需要增加额外机制判断 apps / url 信息是否已完成预加载

不增加额外参数,直接以 children 上的信息进行判断是不是也可以
