前言

之前写过一篇关于微前端乾坤+Angular8的笔记，现在NG9已经到来，因此做了一次升级，仅以此文记录。

安装依赖包

ng add single-spa-angular@4 single-spa@5

打包配置文件

extra-webpack.config.js 同NG8

修改main.single-spa.ts

import { enableProdMode, NgZone, PlatformRef } from '@angular/core';

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { Router } from '@angular/router';
import { AppModule } from './app/app.module';
import { environment } from './environments/environment';
import { singleSpaAngular, getSingleSpaExtraProviders } from 'single-spa-angular';
import { singleSpaPropsSubject, SingleSpaProps } from './single-spa/single-spa-props';

if (environment.production) {
  enableProdMode();
}

// AppModule 只能引用一次，不然会报错
const bootstrapFunction = (ref: PlatformRef) => ref.bootstrapModule(AppModule);

// 单独运行的保障
if (!(window as any).__POWERED_BY_QIANKUN__) {
  bootstrapFunction(platformBrowserDynamic()).catch((err) => console.error(err));
}

const { bootstrap, mount, unmount } = singleSpaAngular({
  bootstrapFunction: (singleSpaProps: SingleSpaProps) => {
    // 入参
    singleSpaPropsSubject.next(singleSpaProps);
    return bootstrapFunction(platformBrowserDynamic(getSingleSpaExtraProviders()));
  },
  template: '<app-root />',
  Router,
  NgZone,
});

export { bootstrap, mount, unmount };

父项目入参处理

修改定义

修改 single-spa文件夹下的single-spa-props.ts文件

import { ReplaySubject } from 'rxjs';
import { AppProps } from 'single-spa';

// Props 发生改变时的订阅
export const singleSpaPropsSubject = new ReplaySubject<SingleSpaProps>(1);

// Add any custom single-spa props you have to this type def
// https://single-spa.js.org/docs/building-applications.html#custom-props
export type SingleSpaProps = AppProps & {
  AccessToken: string; // 传入的参数定义
};

参数使用

在app.component.ts中使用入参

  constructor(public sessionService: SessionService) {
    singleSpaPropsSubject.subscribe(
      (subProps: SingleSpaProps) => {
        if (!!subProps && !!subProps.AccessToken) {
          this.sessionService.AccessToken = subProps.AccessToken;
        }
      },
      (error) => {
        console.error(error);
      }
    );
  }

其他

在需要使用入参的地方视具体情况修改。
