@first-lego-league/ms-messenger v1.4.0

FIRST LEGO Leage messenger

A MHub client working by the FIRST LEGO League TMS Module Standard.

The logic of this module

This module was meant to serve as an extendable messenger which already works by the Module Standard and allows you to easily listen to and send messages. It gives you all the functionality needed for a Mhub messenger running in node or in browser.

In node

The messenger givven in node is fully correlated and logged using ms-logger. It also has a client-id which recognizes it against other clients, and is sent in the headers for recognition.

In browser

In broswer many of these feature are not required or needed. So the client only has a client-id, and isn't correlated or logged.

Authentication

All messengers have the ability to be authenticated using MHub credentials.

Ignoring

All messengers have the ignoreNextMessageOfTopic method, which tells them to ignore the next message of a givven topic.

Stay Alive

All messengers have a failsafe mechanism that makes sure they restart when they get disconnected.

Usage

const { createMessenger } = require('@first-lego-league/ms-messenger')

// Create a new object
const messenger = createMessenger({/* options... */})

messenger.listen('some:topic', (messageData, message) => {
  // do something
})

messenger.send('some:topic', { data: {/* data... */} })
