While working on my application, I encountered a dilemma. I currently pass data from the main component to the subcomponents after pulling it from the API with a single request. Should I continue with this approach or have each component make its own separate API call for data retrieval? The former would result in three network requests on the page.
Another question that arises is whether it's necessary to request data from the API again when the user updates information on any component.
When considering the initial inquiry, it is important to ask whether the subcomponent has the ability to function independently. Is there a scenario where it operates on its own without needing other subcomponents? If so, it should likely manage its own data.
In general, utilizing a service that handles data retrieval and storage is recommended for all components to access their necessary data effortlessly.
As for the second query, providing more context is essential in order to give a proper response. What specific information is being obtained from the API and what type of updates are being made?
