Realtime updates in React: SSE, WebSockets, WebTransport, and more

The text discusses various methods for implementing live updates in React applications, including polling and pushing techniques such as short polling with fetch, long polling with fetch, Server-Sent Events (SSE), WebSockets, a realtime platform like Ably, and the experimental WebTransport. Each method has its advantages and disadvantages, with some being more efficient but resource-intensive, while others are simpler to implement but less effective in terms of latency and network efficiency. The text also highlights that none of these methods are specific to React, as they all rely on JavaScript browser APIs like fetch, WebSockets, and EventSource (SSE).
