// === Arrays

var [a, b] = [1, 2];
console.log(a, b);

# Here's a contrived example of a LEFT JOIN using ARel. This is an example of
# the mechanics, not a real-world use case.

# NOTE: In the gist comments, @ozydingo linked their general-purpose ActiveRecord
# extension that works for any named association. That's what I really wanted!
# Go use that! Go: https://gist.github.com/ozydingo/70de96ad57ab69003446

Redux WebSocket Middleware: Example

This Gist provides some code examples of how to implement WebSocket stream handling using a Redux middleware. Please be aware that this is only provided as an example and that critical things like exception handling have not been implemented.

A more complete version has been packaged, tested, and is available on GitHub as redux-websocket. This library has also been published to npm at @giantmachines/redux-websocket.

Middleware

This module represents the foundation of the middleware and implements the ideas presented above. The exported function is used during the creation of the Redux store (see the following snippet).
