WebSocket ++
C++ websocket client/server library
WebSocket++'s goal is to provide a flexible set of tools for building a wide variety of WebSocket based applications wrapped by low or zero overhead abstractions. It is not opinionated. If something can be practically replacable (with low overhead) based on the user's preference then it is. It accomplishes this via a policy based design built using C++ template metaprogramming. WebSocket++ is a cross platform open source (BSD license) header only C++ library that implements RFC6455 (The WebSocket Protocol) and RFC7692 (Compression Extensions for WebSocket). It allows integrating WebSocket client and server functionality into C++ programs. In its most common configuration full featured network I/O is provided by the Asio Networking Library. Bundled config packages provide sane defaults so most users can get started quickly. As they understand their solution better and want to optimize, the default components can be reconfigured or replaced entirely and transparently. -

tokio-tungstenite
Future-based Tungstenite for Tokio
tokio-tungstenite is a Rust library that connects the Tungstenite WebSocket implementation with the Tokio asynchronous runtime. It lets developers build non-blocking WebSocket clients and servers using Tokio’s async networking model. The crate wraps asynchronous TCP streams and upgrades them into WebSocket streams that integrate naturally with Rust futures and async tasks. It is useful for real-time services, streaming applications, chat systems, gateways, backend infrastructure, and any Rust project that needs WebSocket communication without blocking threads. Because it builds on Tungstenite, it inherits a standards-focused WebSocket protocol foundation while adding Tokio compatibility. It is a practical choice for Rust developers who need efficient, event-driven WebSocket networking. -

IXWebSocket
websocket and http client and server library, with TLS support
IXWebSocket is a C++ library for WebSocket client and server development. It has minimal dependencies (no boost), is very simple to use and support everything you'll likely need for websocket dev (SSL, deflate compression, compiles on most platforms, etc...). HTTP client and server code is also available, but it hasn't received as much testing. It is been used on big mobile video game titles sending and receiving tons of messages since 2017 (iOS and Android). It was tested on macOS, iOS, Linux, Android, Windows and FreeBSD. Two important design goals are simplicity and correctness. -

SockJS-client
WebSocket emulation and Javascript client
SockJS is a browser JavaScript library that provides a WebSocket-like object. SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server. Under the hood SockJS tries to use native WebSockets first. If that fails it can use a variety of browser-specific transport protocols and presents them through WebSocket-like abstractions. SockJS is intended to work for all modern browsers and in environments which don't support the WebSocket protocol, for example, behind restrictive corporate proxies. SockJS-client does require a server counterpart, such as SockJS-node, which is a SockJS server for Node.js. The API should follow HTML5 Websockets API as closely as possible. All the transports must support cross domain connections out of the box. It's possible and recommended to host a SockJS server on a different server than your main web site. -

Socket.IO-client Java
A Socket.IO client library for Java
This is the Socket.IO Client Library for Java, which is simply ported from the JavaScript client. The latest artifact is available on Maven Central. There are several ways to handle events that are transmitted between the server and the client. Add the listener function to the end of the listeners array for the event named eventName. Add a one-time listener function for the event named eventName. Remove the specified listener from the listener array for the event named eventName. Remove all listeners for the specific eventName. Remove all listeners (for any event). Besides emitting and listening to events, the Socket instance has a few attributes that may be of use in your application. Each new connection is assigned a random 20-characters identifier. -

GhostText
Use your text editor to write in your browser
Whenever you’re writing more than a little snippet of code anywhere on the web, activate GhostText to open your preferred text editor and enjoy your own development environment. GhostText is a browser extension that connects to your editor via its own extension. Install both extensions and, if necessary, start the GhostText server in the editor’s extension. Most editor extensions are authored by third parties. You can create more extensions for your favorite editor! Refer to the protocol document. Once you have installed both browser and editor extensions, you can activate GhostText in the current browser tab by clicking its icon in the toolbar or by using a keyboard shortcut. The editor needs to be launched first. In some editors you’ll need to run the Enable GhostText command to start the server. Refer to the documentation of each extension. Sublime Text doesn’t need this step. -

Gorilla WebSocket
Fast, well-tested and widely used WebSocket implementation for Go
Gorilla WebSocket is a Go implementation of the WebSocket protocol. The Gorilla WebSocket package provides a complete and tested implementation of the WebSocket protocol. The package API is stable. An application can also send and receive messages using the io.WriteCloser and io.Reader interfaces. To send a message, call the connection NextWriter method to get an io.WriteCloser, write the message to the writer and close the writer when done. To receive a message, call the connection NextReader method to get an io.Reader and read until io.EOF is returned. The WebSocket protocol distinguishes between text and binary data messages. Text messages are interpreted as UTF-8 encoded text. The interpretation of binary messages is left to the application. The Gorilla WebSocket package passes the server tests in the Autobahn Test Suite using the application in the examples/autobahn subdirectory. -
17
