Display either all potential elements or display only upon request

My app includes a right sidebar that can display chat, help, or search options, based on user input. I noticed that similar apps use hidden nodes rendered in plain HTML when toggling visibility.

I am considering implementing this feature with React, but I understand that React elements have states which trigger the render method. This allows me to store the sidebar's visibility and content within the state.

Is using states in React the best approach for handling this? Should I keep all nodes rendered even if they are not visible, or should I render nodes as needed based on changes in the state?

Answer №1

In my opinion, adhering to the practice of rendering only what is visible would align more closely with the typical React approach. However, in this particular scenario, the decision primarily revolves around performance considerations. Rendering everything and toggling visibility through CSS may result in a longer initial render time (although the difference may not be significant or noticeable). On the other hand, rendering only the visible section requires React to perform a small rerender whenever the sidebar content is updated (which may also go unnoticed in terms of time).

If you are looking to assess performance, I suggest experimenting with both approaches. Ultimately, I believe that either method should serve you adequately.
