bus

This message bus is the foundation of the Theatersoft platform. It enables communication between host Node.js servers and client web browsers to create a distributed application using modern Javascript.

Example: Ping Service

This demonstrates a simple ping method call between two bus nodes.

In this doc, node may refer to either Node.js or a node element of a bus network, depending on context.

First, install the package: npm install @theatersoft/bus.

Terminal 1

Start node and enter:

const {bus} = require('@theatersoft/bus')
bus.start({children: {host: 'localhost', port: 5453}})

This root bus node is now listening for child connections to localhost:5453.

Register a bus object Ping with one method ping:

bus.registerObject('Ping', {ping: () => 'PING!'})

Terminal 2

Open another terminal, start another node, and run:

const {bus} = require('@theatersoft/bus')
bus.start({parent: 'ws://localhost:5453'})

This child bus node is now connected to the parent.

Call the method on the bus object running in terminal 1:

const Ping = bus.proxy('Ping')
Ping.ping().then(value => console.log(value))

PING!
