primus - :zap: Primus, the creator god of the transformers & an abstraction layer for real-time to prevent module lock-in

•    Javascript

---

Primus, the creator god of transformers but now also known as universal wrapper for real-time frameworks. There are a lot of real-time frameworks available for Node.js and they all have different opinions on how real-time should be done. Primus provides a common low level interface to communicate in real-time using various real-time frameworks.If you deploy your application behind a reverse proxy (Nginx, HAProxy, etc.) you might need to add WebSocket specific settings to its configuration files. If you intend to use WebSockets, please ensure that these settings have been added. There are some example configuration files available in the observing/balancerbattle repository.

Squiss - High-volume Amazon SQS Poller for Node.js

•    Javascript

---

Squiss aims to process as many messages simultaneously as possible. Set the maxInFlight option to the number of messages your app can handle at one time without choking, and Squiss will attempt to keep that many messages flowing through your app, grabbing more as you mark each message as handled or ready for deletion. If the queue is empty, Squiss will maintain an open connection to SQS, waiting for any messages that appear in real time. By default, anyway. You can configure it to poll however you want. Squiss don't care. Don't be scared of new -- you need to create a new Squiss instance for every queue you want to poll. Squiss is an EventEmitter, so don't forget to call squiss.on('message', (msg) => msg.del()) at the very least.

kb-controls - present a polling interface for keyboard state given a binding object

•    Javascript

---

expose a polling object for (game) keybindings using vkey definitions. Events are great! I love them. But when you're writing game logic, oftentimes you want the frame event to drive the simulation -- and dealing with the keyboard as a separate evented interface can be troublesome in this regard.

sse-dash - Node.js & Aura.js demonstrating SSE (Server Side Events)

•    Javascript

---

The backend server is implemented in Node.js and the frontend is mostly using aura.js to provide isolated (and reusable!) widgets to connect to the different SSE endpoints. The demo currently shows connected server peers, the latest article from the NPMjs.org RSS feed and the servers current date & time, all in realtime. and finally open http://127.0.0.1:3000.

toiler - Toiler is a AWS SQS long-polling thread-based message processor.

•    Ruby

---

Toiler is a AWS SQS long-polling thread-based message processor. It's based on shoryuken but takes a different approach at loadbalancing and uses long-polling. Toiler allows to specify the amount of processors (threads) that should be spawned for each queue. Instead of shoryuken's loadbalancing approach, Toiler delegates this work to the kernel scheduling threads.

promise-poller - A basic poller built on top of promises

•    Javascript

---

A basic poller built on top of promises. You can use any promise library that is Promises/A+ compliant. Sometimes, you may perform asynchronous operations that may fail. In many of those cases, you want to retry these operations one or more times before giving up. promise-poller handles this elegantly using promises.
