Atmosphere - Realtime Client Server Framework for the JVM

•    Java

---

The Atmosphere Framework contains client and server side components for building Asynchronous Web Applications. It transparently supports WebSockets, Server Sent Events (SSE), Long-Polling, HTTP Streaming (Forever frame) and JSONP. Its mission is to make real time apps possible in every browser, library and mobile device, blurring the differences between the different transport mechanisms.

angelo - Sinatra-like DSL for Reel that supports WebSockets and SSE

•    Ruby

---

A Sinatra-like DSL for Reel. Angelo also features before and after filter blocks, just like Sinatra. Filters are ordered as defined, and called in that order. When defined without a path, they run for all matched requests. With a path, the path is interpreted as a Mustermann pattern and params are merged. before filters can set instance variables which can be used in the route block and the after filter. For more info on the difference in how after blocks are handled, see the Errors section below for more info.

EventSource - a polyfill for http://www.w3.org/TR/eventsource/

•    Javascript

---

Just include src/eventsource.js or src/eventsource.min.js in your page to use the polyfill. Unless a typescript definition file is created for this polyfill, this is how you would use it in an Ionic2 project. It should (in theory) be very similar in an Angular2 project.

sse-chat - Chat example app using Server Sent Events plus REST calls

•    Scala

---

This is a simple chat application using Play Framework together with AngularJS. It makes use of a Concurrent.Broadcast object as an Enumerator, a filtering Enumeratee and EventSource as the Iteratee. Together these building blocks facilitate the chat message data flow within the application. Check out the live demo.

Sequence-Semantic-Embedding - Tools and recipes to train deep learning models and build services for NLP tasks such as text classification, semantic search ranking and recall fetching, cross-lingual information retrieval, and question answering etc

•    Python

---

SSE(Sequence Semantic Embedding) is an encoder framework toolkit for natural language processing related tasks. It's implemented in TensorFlow by leveraging TF's convenient deep learning blocks like DNN/CNN/LSTM etc. Depending on each specific task, similar semantic meanings can have different definitions. For example, in the category classification task, similar semantic meanings means that for each correct pair of (listing-title, category), the SSE of listing-title is close to the SSE of corresponding category. While in the information retrieval task, similar semantic meaning means for each relevant pair of (query, document), the SSE of query is close to the SSE of relevant document. While in the question answering task, the SSE of question is close to the SSE of correct answers.

nchan - Fast, horizontally scalable, multiprocess pub/sub queuing server and proxy for HTTP, long-polling, Websockets and EventSource (SSE), powered by Nginx

•    C

---

Nchan is a scalable, flexible pub/sub server for the modern web, built as a module for the Nginx web server. It can be configured as a standalone server, or as a shim between your application and hundreds, thousands, or millions of live subscribers. It can buffer messages in memory, on-disk, or via Redis. All connections are handled asynchronously and distributed among any number of worker processes. It can also scale to many Nginx servers with Redis. Messages are published to channels with HTTP POST requests or Websocket, and subscribed also through Websocket, long-polling, EventSource (SSE), old-fashioned interval polling, and more.

Simd - C++ image processing library with using of SIMD: SSE, SSE2, SSE3, SSSE3, SSE4

•    C++

---

The Simd Library is a free open source image processing library, designed for C and C++ programmers. It provides many useful high performance algorithms for image processing such as: pixel format conversion, image scaling and filtration, extraction of statistic information from images, motion detection, object detection (HAAR and LBP classifier cascades) and classification, neural network. The algorithms are optimized with using of different SIMD CPU extensions. In particular the library supports following CPU extensions: SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2 and AVX-512 for x86/x64, VMX(Altivec) and VSX(Power7) for PowerPC (big-endian), NEON for ARM.

eventsource - Server-sent events for Go

•    Go

---

eventsource provides server-sent events for net/http server.

atmosphere-samples - Atmosphere's samples.

•    Javascript

---

Recommended samples for getting started are the chat, which demonstrate usage of all transports using an AtmosphereHandler, or the jquery-pubsub, which demonstrate how to switch from one transport to another using a Jersey Resources. If you are interested to write WebSocket only application, take a look at the atmosphere-websockethandler-pubsub sample. The pubsub sample contains a lot of small demonstration on how the Jersey extension can be used. If you are interested to write HTML5 Server Side Events application, take a look at the atmosphere-sse-xxx samples. If you plan to use Spring or GWT, take a look at their specific samples.

Simple Sharing Extensions (SSE) for .NET

SSE is an XML micro-format and corresponding sync algorithm that can be embedded in RSS or Atom feeds to allow for two-way synchronization among peers. More important: the algorithm allows for mesh-style synchronization between nodes, with no concept of a "master" copy. This c...

goirc - Event-based stateful IRC client framework for Go.

•    Go

---

See fix/goirc.go and the README there for a quick way to migrate from the old go1 API. The test client provides a good (if basic) example of how to use the framework. Reading client/handlers.go gives a more in-depth look at how handlers can be written. Commands to be sent to the server (e.g. PRIVMSG) are methods of the main *Conn struct, and can be found in client/commands.go (not all of the possible IRC commands are implemented yet). Events are produced directly from the messages from the IRC server, so you have to handle e.g. "332" for RPL_TOPIC to get the topic for a channel.

jobs - A persistent and flexible background jobs library for go.

•    Go

---

A persistent and flexible background jobs library for go.Jobs is intended to be used in web applications. It is useful for cases where you need to execute some long-running code, but you don't want your users to wait for the code to execute before rendering a response. A good example is sending a welcome email to your users after they sign up. You can use Jobs to schedule the email to be sent asynchronously, and render a response to your user without waiting for the email to be sent. You could use a goroutine to accomplish the same thing, but in the event of a server restart or power loss, the email might never be sent. Jobs guarantees that the email will be sent at some time and allows you to spread the work between different machines.

Blazor - Build client web apps with C#

•    CSharp

---

Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code is written in C#, allowing you to share code and libraries.

In many modern web applications, WebSockets are used to implement realtime, live-updating user interfaces. When some data is updated on the server, a message is typically sent over a WebSocket connection to be handled by the client. This provides a more robust, efficient alternative to continually polling your application for changes. To assist you in building these types of applications, Laravel makes it easy to "broadcast" your events over a WebSocket connection. Broadcasting your Laravel events allows you to share the same event names between your server-side code and your client-side JavaScript application.
