What is the best way to display a single instance of a React component that is declared in multiple locations within the app?

Imagine I have 2 main components, A and B. Now, component C needs to be created inside both A and B. How can I guarantee that the same exact instance of C is generated in both places? Essentially, I want them to stay synchronized - any changes made to one should automatically reflect in the other.

I attempted using the same key value for both components, but unfortunately, it didn't solve my issue.

Answer №1

It is important to note that having React elements in separate parts of the tree will always create distinct instances.

To ensure synchronized behavior between two sections of the component tree, a common technique is to lift state up to a shared ancestor component. This higher-level component manages the logic and state for both descendant components, passing down necessary values via props or context when needed.
