🔁Real-time updates enable updating the user interface in real time.
🔄There are multiple strategies to achieve real-time updates, including pull and push.
⏳Short polling is a simple but inefficient technique for real-time updates.
🕒Long polling is a more efficient approach that offers nearly real-time updates.
🌐Websockets and server-sent events are dedicated technologies for real-time updates.
What are real-time updates?
—Real-time updates refer to updating the user interface in real time, providing the latest information to the user.
What strategies are used for real-time updates?
—Pull and push are two common strategies used for real-time updates. Pull involves the client requesting updates from the server, while push involves the server sending updates to the client.
What is short polling?
—Short polling is a technique where the client periodically requests updates from the server. It can be inefficient as it makes frequent requests, even when there are no updates.
What is long polling?
—Long polling is a technique where the client sends a request to the server, but the server holds the response until new data becomes available. It is a more efficient approach for real-time updates.
What are websockets and server-sent events?
—Websockets and server-sent events are dedicated technologies for real-time updates. They provide efficient bidirectional communication between the client and server.
