react-broadcast - Reliably communicate state changes to deeply nested React elements

Javascript

react-broadcast provides a reliable way for React components to propagate state changes to their descendants deep in the component hierarchy, bypassing intermediaries who return false from shouldComponentUpdate.It was originally built to solve issues that arose from using react-router together with react-redux. The router needed a safe way to communicate state changes to <Link>s deep in the component hierarchy, but react-redux relies on shouldComponentUpdate for performance. react-broadcast allows the router to work seamlessly with Redux and any other component that uses shouldComponentUpdate.

eventemitter3 - EventEmitter3 - Because there's also a number 2. And we're faster.

Javascript

It's a drop in replacement for existing EventEmitters, but just faster. Free performance, who wouldn't want that? The EventEmitter is written in EcmaScript 3 so it will work in the oldest browsers and node versions that you need to support.We've upgraded the API of the EventEmitter.on, EventEmitter.once and EventEmitter.removeListener to accept an extra argument which is the context or this value that should be set for the emitted events. This means you no longer have the overhead of an event that required fn.bind in order to get a custom this value.

PubSubJS - Dependency free publish/subscribe for JavaScript

Javascript

PubSubJS is a topic-based publish/subscribe library written in JavaScript. PubSubJS has synchronisation decoupling, so topics are published asynchronously. This helps keep your program predictable as the originator of topics will not be blocked while consumers process them.

hemera - 🔬 Writing reliable & fault-tolerant microservices with https://nats.io

Javascript

Hemera (/ˈhɛmərə/; Ancient Greek: Ἡμέρα [hɛːméra] "day") is a small wrapper around the NATS driver. NATS is a simple, fast and reliable solution for the internal communication of a distributed system. It chooses simplicity and reliability over guaranteed delivery. We want to provide a toolkit to develop micro services in an easy and powerful way. We provide a pattern matching RPC style. You don't have to worry about the transport. NATS is powerful.Hemera has not been designed for high performance on a single process. It has been designed to create lots of microservices doesn't matter where they live. It choose simplicity and reliability as primary goals. It act together with NATS as central nervous system of your distributed system. Transport independency was not considered to be a relevant factor. In addition we use pattern matching which is very powerful. The fact that Hemera needs a broker is an argument which should be taken into consideration when you compare hemera with other frameworks. The relevant difference between microservice frameworks like senecajs, molecurer is not the performance or modularity its about the complexity you need to manage. Hemera is expert in providing an interface to work with lots of services in the network, NATS is the expert to deliver the message at the right place. Hemera is still a subscriber of NATS with some magic in routing and extensions. We don't have to worry about all different aspects in a distributed system like routing, load-balancing, service-discovery, clustering, health-checks ...

emittery - Simple and modern async event emitter

Javascript

It's only ~200 bytes minified and gzipped. I'm not fanatic about keeping the size at this level though.Emitting events asynchronously is important for production code where you want the least amount of synchronous operations.

Mediator.js - An implementation of the mediator pattern for asynchronous events in Javascript

Javascript

Mediator is a simple class that allows you to register, unregister, and call subscriber methods to help event-based, asyncronous programming. Its purpose is to make the usage of WebSockets, Ajax calls, DOM events, or any other asynchronous operations easy to maintain and test. Mediator has no dependencies on any other libraries.

hapi-socketio-redis-chat-example - :speech_balloon: Real-time Chat using Hapi

Node.js Chat Apps are practically the "Hello World" of real-time apps. If you Google for "node.js chat example" you will see thousands of results! But ... 90% of the examples use Express.js, 95% use MongoDB to store data/messages and 100% have zero tests. So, this example is for the the people who prefer to have examples that are fully explained (including tests). As with all our examples we have a suite of tests.
