Web Sockets are typically a preferable option for a real-time chat application that needs to function on any kind of network.
Here's why.
Why WebSockets?
- Client-Server Model: WebSockets are designed with a client-server architecture, which is excellent for a chat application in which a central server maintains communication among several clients. This configuration makes it easier to manage users from diverse networks, especially those behind NATs (Network Address Translation) or firewalls.
- Network Compatibility: WebSockets use TCP, which is supported by almost all networks. This increases its reliability under a wider range of network situations, such as limited corporate environments or mobile networks.
- WebSockets ensure that messages are delivered in a timely and orderly manner. This is vital for chat applications that require message ordering and delivery guarantees.
- Ease of Implementation: Implementing WebSockets is simple, with widespread support on both server-side (e.g., Node.js, Python, Java) and client-side (e.g., browsers, mobile
- Scalability: WebSocket servers can be scaled horizontally by sharing connections among several servers. This is crucial to supporting a high number of users simultaneously.
Conclusion
WebSockets is the preferred method for creating a simple, dependable, and scalable real-time chat application that operates over multiple networks.
