The bus

The bus is the communications channel which links all your services together. Currently this is Redis.

You use lightbus.create() in your file to access this bus:


import lightbus

bus = lightbus.create()

This creates a high-level client through which you can call RPCs and fire events.

About buses

In computing, a bus is a shared communication medium. A bus allows any software/hardware connected to that medium to communicate, as long as common rules are obeyed. In this sense a bus is very similar to a conversation between a group of people.

In electronics the communication medium can be a simple copper cable. In software the communication medium is itself defined by software.

Lightbus uses Redis as its communication medium, although support for other mediums may be added in future.
