React.js - flux vs global event bus

Question

What is the advantage of using Flux over a global event bus? I think the dispatcher is all that is needed:

1. component publishes \'user event\' with data to the dis

Answer 1

You basically described flux, the only difference is:

4. stores emit a change event

And the component updating its state isn't part of flux, that's a common practice for integrating flux and react.

Flux just names each of these pieces and gives guidelines on what each piece's responsibility is.

It's essentially a main event emitter (dispatcher), the event types (actions), functions that emit an event on the dispatcher (action creators; the event body is a payload), and other event emitters that: keep state, listen to the dispatcher and emit change events (stores).

At least that's how it works in JS. The core principle is the unidirectional data flow. There are plenty of event emitters that are used for bidirectional communication.
