如何解决角度内存泄漏

Question

In order to optimize Garbage Collector manually, how can we forcefully push variables to the garbage collector? Like if we have a root/global level variable in one angular component, and then when we are switching from that page to another - we won't need the global variables in that page? How can we move to garbage collector?

If we do variable = null or variable = undefined on ngOnDestroy() like we unsubscribe from observables, would that help?

Strategies to prevent leaks

• Nullify all references to models in a component on the component $destroy phase

• Try to remove all circular dependencies by using yet another layer of indirection

• Create a this.state object to manage the instance state in a place for easier nullification

• Dispose subscriptions

• Examine third party software and decide to use it or not also based on memory problems or contribute with PRs
