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. -

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. -

Open Source WebSocket Libraries Guide
Getting started with using open source websocket libraries is a great way to create real-time applications quickly. Here are the steps to get up and running:
- Choose Your Library: Before you can get started, you need to decide which websocket library to use. There are many open source libraries available for different programming languages such as HTML5 WebSocket, Node.js, Java Script, Photon, etc. Consider the features offered by each library and choose the one that best suits your project needs.
- Install the Library: Once you’ve chosen your library, it’s time to install it onto your system or computer. Most of these libraries come in packages that include documentation or guides on installation procedures so make sure to read through them before proceeding with installation.
- Connecting Clients and Servers: Websockets require a client–server connection between two endpoints (tools) in order for data transfer to be successful. Before you can start sending data back & forth between two computers or devices, make sure both ends of the connection are properly initialized by writing code according to guidelines provided by your chosen library/framework package.
- Sending & Receiving Data: Once connected, you can start exchanging messages between clients and servers using various protocols (e.g., TCP/IP). Make sure to research which protocol works best for your application and how it should be used correctly before continuing any further steps towards development.
- Developing Applications: Now that everything is set up properly, it’s time for the fun part - developing web applications. With websockets being an enabler of real-time communication between browsers & servers online, developers have endless opportunities when crafting their projects using this technology. Just remember to keep in mind all security concerns related with data transmissions across networks while creating apps with this technology.
If you’ve followed these 5 steps, then you should be all set up and ready to start building your own web applications using open source websocket libraries. Good luck.
