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. -

ws
Tiny WebSocket library for Go
Zero-copy upgrade. No intermediate allocations during I/O. Low-level API which allows building your own logic of packet handling and buffers reuse. High-level wrappers and helpers around API in wsutil package, which allow to start fast without digging the protocol internals. Existing WebSocket implementations do not allow users to reuse I/O buffers between connections in clear way. This library aims to export efficient low-level interface for working with the protocol without forcing only one way it could be used. Library is tagged as v1* so its API must not be broken during some improvements or refactoring. Example applications using ws are developed in separate repository ws-examples. We can apply the same pattern to read and write structured responses through a JSON encoder and decoder.Zero-copy upgrade helps to avoid unnecessary allocations and copying while handling HTTP Upgrade request. -

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.
