stream-chat-react VS react-virtuoso

In part one of the series, we did not cover any UI work and instead focused on setting up the project and integrating the Stream Chat SDK. Having laid this groundwork, we can now start implementing the UI.

Here, Dillion Megida, frontend developer advocate for Stream, shares how to build a Slack clone using the Stream React Chat SDK. This hour-long tutorial demonstrates how to customize components, create developer tokens, query and join channels, and leverage the Stream UI kit for a polished user experience.

Check out Stream on Github. They have a few chat SDKs for iOS, Android, React and a few others. Website: https://getstream.io/

react-virtualized is very old and unmaintained. I will plug my fairly popular solution, https://github.com/petyosi/react-virtuoso.

Try virtualization inside your dropdown. For sure it will improve the performance. Check https://virtuoso.dev it's very easy to implement

Shameless plug, I am the author: https://github.com/petyosi/react-virtuoso

I would take a look at React Virtuoso

if it is group chat that many users can write messages into one group means it will be a lot from some point. and suppose there is another list for example user contact list in aside along with chat section, size of dom will grow in app. when user select some contact item react gets sluggish from its rerender aspect. but I don't recommend to start with it unless you are not observe performance issues and app layout is simple to implement this feature there is also https://virtuoso.dev/ for virtualization FYI.

react-virtuoso is a relatively new package for virtualization, published first two years ago. It comes with all the necessary features and support that one might eventually require in a developing project.

So far, react-virtuosso https://virtuoso.dev/ is the only library that supports this.

In many large companies, development becomes slow and incredibly expensive. If an engineer costs 10k a month, the fully burdened cost to the company is often 5-10x that. While the costs increase the output usually goes down. This is something I’ve been thinking about a lot over the last months. As our startup keeps on growing I want to hold on to that startup level of productivity. Petyo just joined as our 100nd team member, so as we reach this initial level of scale this is becoming a more urgent concern.
