What are websockets?
WebSockets are a special kind of communication method that allows for a two-way real-time connection between a web browser (client) and a server. This is different from regular web traffic, which typically uses a request-response model.
Imagine a regular conversation: you ask a question, and the other person answers. That’s similar to how traditional web traffic works. With WebSockets, it’s more like a live chat – both people can talk and listen at the same time.
Here are some key benefits of WebSockets:
- Real-time communication: Data can be exchanged instantly between the client and server, enabling features like live chat and multiplayer games.
- Reduced overhead: Compared to constant polling (checking for updates frequently), WebSockets use less resources to maintain the connection.
- Full-duplex communication: Both the client and server can send and receive data at the same time.
WebSockets are used in many applications that require real-time updates, such as:
- Chat applications
- Stock tickers
- Collaborative editing tools
- Multiplayer games
If you’ve ever used a chat app that shows messages as soon as they are typed, or a collaborative document where changes appear instantly for all editors, then you’ve likely encountered WebSockets in action.
