tx, found the workaround I needed:

<pre><code> constructor(private zone:NgZone) {
 // enable to for time travel
 this.appStore.subscribe((state) =&gt; {
 this.zone.run(() =&gt; {
 console.log('enabled time travel');
 });
 });
</code></pre>

running zone.run will force the component to re-render

blocks|key|4437958|text|这里的其他答案提供了触发更改检测周期的解决方案，这些周期将更新组件的视图(这与完全重新呈现不同)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4437959|完全重新渲染，这将销毁并重新初始化组件(调用所有生命周期挂钩并重建视图)，可以通过以下方式使用ng-template、ng-container和ViewContainerRef来完成：|offset|length|style|CODE|4437960|<div>
++<ng-container+#outlet+>
++</ng-container>
</div>

<ng-template+#content>
++<child></child>
</ng-template>|code-block|syntax|javascript|4437961|然后，在引用了#outlet和#content的component中，我们可以清除outlets的内容并插入子组件的另一个实例：|4437962|@ViewChild("outlet",+{read:+ViewContainerRef})+outletRef:+ViewContainerRef;
@ViewChild("content",+{read:+TemplateRef})+contentRef:+TemplateRef<any>;

private+rerender()+{
++++this.outletRef.clear();
++++this.outletRef.createEmbeddedView(this.contentRef);
}|4437963|此外，应该在AfterContentInit钩子上插入初始内容：|4437964|ngAfterContentInit()+{
++++this.outletRef.createEmbeddedView(this.contentRef);

Other answers here provide solutions for triggering change detection cycles that will update component's view (which is not same as full re-render).

Full re-render, which would destroy and reinitialize component (calling all lifecycle hooks and rebuilding view) can be done by using <code>ng-template</code>, <code>ng-container</code> and <code>ViewContainerRef</code> in following way:

<pre><code>&lt;div&gt;
 &lt;ng-container #outlet &gt;
 &lt;/ng-container&gt;
&lt;/div&gt;

&lt;ng-template #content&gt;
 &lt;child&gt;&lt;/child&gt;
&lt;/ng-template&gt;
</code></pre>

Then in component having reference to both <code>#outlet</code> and <code>#content</code> we can clear outlets' content and insert another instance of child component:

<pre><code>@ViewChild("outlet", {read: ViewContainerRef}) outletRef: ViewContainerRef;
@ViewChild("content", {read: TemplateRef}) contentRef: TemplateRef&lt;any&gt;;

private rerender() {
 this.outletRef.clear();
 this.outletRef.createEmbeddedView(this.contentRef);
}
</code></pre>

Additionally initial content should be inserted on <code>AfterContentInit</code> hook:

<pre><code>ngAfterContentInit() {
 this.outletRef.createEmbeddedView(this.contentRef);
}
</code></pre>

blocks|key|4438022|text|我使用*ngIf强制重新加载我的组件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4438023|容器中的所有组件都返回到完整的生命周期钩子。|4438024|在模板中：|4438025|<ng-container+*ngIf="_reload">

I force reload my component using *ngIf.

All the components inside my container goes back to the full lifecycle hooks .

In the template : 

<pre><code>&lt;ng-container *ngIf="_reload"&gt;
 components here 
&lt;/ng-container&gt;
</code></pre>

Then in the ts file :

<pre><code>public _reload = true;

private reload() {
 setTimeout(() =&gt; this._reload = false);
 setTimeout(() =&gt; this._reload = true);
}
</code></pre>
