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. -

RESTinio
HTTP/WebSocket server C++14 library
RESTinio is a header-only C++14 library that gives you an embedded HTTP/WebSocket server. It is based on the standalone version of ASIO and is targeted primarily for the asynchronous processing of HTTP requests. Since v.0.4.1 Boost::ASIO (1.66 or higher) is also supported. Consider the task of writing a C++ application that must support some REST API, RESTinio represents our solution for that task. Server runs on the main thread, and responds to all requests with a hello-world message. Of course, you've got access to the structure of a given HTTP request, so you can apply complex logic for handling requests. Async request handling. Cannot get the response data immediately? That's ok, store the request handle somewhere and/or pass it to another execution context and get back to it when the data is ready. -

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. -

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. -

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. -
22
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. -
