    Rhubarb

    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

    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.

    WebSocket ++

    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.

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

How To Get Started With Open Source WebSocket Libraries

Users can get started with using open source websocket libraries by first selecting the library that works best for their needs. There are many libraries available, such as Java, JavaScript, Python, and Ruby. Once the library has been selected, the user will need to download it from the library's official website. After downloading the library files to their computer, they should unzip them into a folder they can easily locate.

Next, they will need to install any required dependencies and configure it correctly. The installation and configuration process may vary depending on which operating system is running on their computer or server. Depending on the complexity of their application's websocket requirements, users may also want to set up an authentication strategy and data validation protocol before connecting it to a websocket server.

After all of these steps have been completed successfully, users can start writing code that interacts with websockets. This could involve writing client-side scripts that use JavaScript to communicate with a server via websockets, or building out a server-side application in Java or Python that listens for incoming connections over websockets and handles incoming messages accordingly.

Overall, getting started with using open source websocket libraries is relatively straightforward once users select and download the right library for their particular environment and setup any required dependencies correctly. With some familiarity of coding in whatever language they are working with (JavaScript, Java, Python, etc.), users should be able to have an application up and running with features powered by web sockets in no time.
