Can we stop Angular components from being destroyed during navigation?

Consider the scenario where I have two distinct Angular 2 components known as ComponentA and ComponentB. My goal is to navigate from ComponentA to ComponentB and then return to ComponentA without needing to reinitialize it.

In the current setup of Angular 2 Router, whenever I move away from a component, that particular component undergoes destruction and needs to be created again once I revisit it.

I am aware that one way to maintain the state of components is by leveraging a Service, but this approach appears to be more like a temporary fix instead of a permanent solution. Are there any alternatives to this dilemma?

Answer №1

A solution to this is implementing the RouteReuseStrategy in your Angular application.

This allows you to define how routes reuse components, providing more control over navigation behavior.
