Java WebSockets
A barebones WebSocket client and server implementation
This repository contains a barebones WebSocket server and client implementation written in 100% Java. The underlying classes are implemented java.nio, which allows for a non-blocking event-driven model (similar to the WebSocket API for web browsers). The org.java_websocket.server.WebSocketServer abstract class implements the server-side of the WebSocket Protocol. A WebSocket server by itself doesn't do anything except establish socket connections though HTTP. After that it's up to your subclass to add purpose. The org.java_websocket.client.WebSocketClient abstract class can connect to valid WebSocket servers. The constructor expects a valid ws:// or wss:// URI to connect to. Important events onOpen, onClose, onMessage and onError get fired throughout the life of the WebSocketClient, and must be implemented in your subclass. -

GraphQL WebSocket
Coherent, zero-dependency, lazy, simple, GraphQL
Coherent, zero-dependency, lazy, simple, GraphQL over WebSocket Protocol compliant server and client. Messages are represented through the JSON structure and are stringified before being sent over the network. They are bidirectional, meaning both the server and the client must conform to the specified message structure. Connection is a connection within the established socket describing a "connection" through which the operation requests will be communicated. The server can close the socket (kick the client off) at any time. The close event dispatched by the server is used to describe the fatal error to the client. The client closes the socket and the connection by dispatching a 1000: Normal Closure close event to the server indicating a normal closure. -

Rhubarb
A WebSocket library optimized for multiplayer JS games
Rhubarb is a lightweight WebSocket library for multiplayer HTML5 games. It is originally designed to be used by the ROYGBIV Engine. However, it can be used outside of ROYGBIV as well. Javascript is slow, therefore we want to have as much main-process-power as we can in order to do game related calculations, graphics rendering and achieving 60 FPS. For multiplayer games achieving 60 FPS gets even more complicated given that transferring data over WebSockets is a slow operation. It also triggers GC activity by copying the transferred data (if JSON is the preferred way), which eventually slows down the main thread as well. -

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. -

Guide to Open Source WebSocket Servers
Open source websocket servers are an important part of web development, as they provide a way to connect browsers and web applications with each other in real-time. They can be used for a variety of purposes, from streaming data to creating multiplayer games. A websocket server is essentially a TCP server that runs over the web and uses the websocket protocol to communicate with clients. This allows for two-way communication between connected browsers and servers, allowing them to exchange messages in real time without having to reload the page. Some of the most popular open source websocket servers include Socket.io, Ratchet, WAMP, Faye and WebSocketClientServer.
Socket.io is one of the most widely used open source websocket servers due to its powerful features such as robust event handling and support for multiple transport protocols like XHR polling, HTML streaming and more. It also provides easy access to popular libraries like jQuery and Backbone so developers can quickly build interactive applications using these frameworks. Additionally, it has many built-in features such as connection persistence and binary data support which makes it convenient for developers working on complex projects.
Ratchet is another popular open source websocket server designed specifically for PHP applications. It supports multiple protocols including its own native protocol known as WAMP (Websockets Application Messaging Protocol) along with HTTP Streaming Protocols including HTTTP 1/1 upgrade mechanism that allows browser clients to upgrade their connection requests when needed during long connections. It also provides API hooks which make it easier for developers to integrate their own custom authentication methods into their existing applications or create their own messaging systems from scratch using Ratchet’s library of components.
WAMP (Websockets Application Messaging Protocol) is an open protocol that enables communication between client-server applications over WebSockets connections while supporting both RPC (Remote Procedure Calls) scripting across different programming languages such as JavaScript on the client side and Python or PHP on the server side. Additionally, WAMP includes traditional Unix signal handlers which allow developers greater control over how incoming messages are handled by application logic written on either side without needing special code each time a message arrives at either end point. Thanks this flexibility, WAMP avoids unnecessary message flooding due to misconfigured tools or software bugs making it perfect choice for large scale distributed systems.
Faye is another high performance open source websocket server offering publish/subscribe messaging features, enabling efficient one-to-many communications through backend services. Its architecture design allows users who subscribe topics receive updates whenever messages published onto those topic are received by Faye server. Furthermore, Faye provide application level security measures via token based authentication along with TLS encryption support ensuring secure transmission transmissions between clients. Lastly, Faye supports many commonly used transports including WebSockets, XMLHttpRequest, JSONP & SSE making it easier than ever before integrate component into existing system architectures effectively.
WebSocketClientServer is another great open source WebSocketServer implementation that provides an easy interface allowing developers easily get up running without having learn too much new technology stack from scratch. It utilizes Java NIO techniques utilizing non blocking IO techniques providing efficient memory usage within backend services while still maintaining low latency communication performances even under extreme load scenarios thanks careful multi threading management implemented within underlying codebase itself. Furthermore, unlike some other server alternatives mentioned here, this library provides ability customize header information sent back forth between clients further enhancing potential security aspects when necessary terms of certain projects demands arise from client requirements if needed be done properly.
In conclusion, open source websocket servers provide an efficient way to connect browsers and web applications in real time. There are a variety of popular open source websocket servers available that offer different features and advantages making them suitable for various projects. Some of the most popular include Socket.io, Ratchet, WAMP, Faye and WebSocketClientServer.

How Users Can Get Started With Open Source WebSocket Servers
Getting started with open source websocket servers can be a relatively simple process. First, you'll need to decide which websocket server to use.
Once you know which websocket server you want to use, the next step is downloading the appropriate files from their respective websites and installing them on your web server. Depending on which websocket server you're using, the installation instructions will vary; so make sure you read any accompanying documentation closely for best results.
Now that your websocket server is installed, it's time to configure it to suit your needs. You may need to write some code in order to further customize the settings of your websocket connection but this should be fairly straightforward if you've already downloaded all the necessary files and followed all of the setup instructions correctly.
Finally, when everything is configured properly and running as expected, it's time to put your open source web socket server into action by writing client-side JavaScript code that interacts with it. The exact JavaScript syntax will depend on which websocked server you are using; so once again check out each project's website for details about how their particular API works so you don't get lost along the way.
Following these steps should allow you to quickly and easily get started with open source web socket servers.
