Websocket server


Managed WebSocket Server API, pub-sub and scalable biredetional communication solutions

Previous Page. Next Page . A Web Socket server is a simple program, which has the ability to handle Web Socket events and actions. It usually exposes similar methods to the Web Socket client API and most programming languages provide an implementation. The following diagram illustrates the communication process between a Web Socket server and a Web A WebSocket server can receive events from clients, process them to update the application state, and synchronize the resulting state across clients. Here’s an example where any client can increment or decrement a counter. Updates are propagated to all connected clients.

WebSocket enables bidirectional communication in real time over the web. WebSocket can be run together with a normal HTTP server. The Websocket protocol enables the interaction between a client (the web browser) and a web server (in our case an ESP32 Websocket server). The interesting aspect of this protocol is that it enables real-time data exchange between the web client and the web server. A WebSocket server is nothing more than an application listening on any port of a TCP server that follows a specific protocol. The task of creating a custom server tends to scare people; however, it can be straightforward to implement a simple WebSocket server on your platform of choice.

This means all we need is a way for the client and the server to agree to hold the socket connection open and repurpose it for ongoing WebSocket servers act similarly to the TcpListener, and listen for connections. See the Server struct documentation for more information. The bind() and bind_secure() functions will bind the server to the given SocketAddr.
