描述

rootApp.getAppOnceAvailable$('SomeAppName')
  .subscribe(someApp => console.log(someApp));

rootApp.getAppOnceAvailable$(['SomeApp', 'AnotherApp'])
  .subscribe(function (someApp, anotherApp) {

研究方向

Examine the current implementation of `getAppOnceAvailable$` in the frint.js codebase (likely in the core package). Understand how it subscribes to app availability. Then design a solution that accepts an array and uses `forkJoin` or `combineLatest` to emit when all apps are available. Check if any similar pattern exists in the repository. The existing comment may contain hints; review issue #425 for any follow up discussion.
