如何防止新选项卡中的Angular渲染组件

Question

I have an Angular component that should be rendered only once, on the first screen of the app, and not every time I open a tab.

Using localStorage to mark the component as active is a bit problematic since one can close the browser and it will be hard to track that.

如果使用* ngIf隐藏组件，则每次打开选项卡时都会使用角度渲染组件，这是很合逻辑的，请尝试使用： [hidden]="!expression"而不是*ngIf="expression"
