BeHave Tracking Client

This library contains the BeHave tracking client, it is intended to use it inside a client application integration and not standalone.

Getting Started

Prerequisites

• Node 10
• NPM 6.4.1

Specification

The tracking client library register in a global namespace and forward all valid events to the BeHave tracking websocket server, invalid events will be droped. The library communicates with BeHave.tracking-service.

How to use

config

const config = {
  NAMESPACE: 'test',
  ENDPOINT: ' wss://behave.test.at/ws/event',
  RECONNECT_TIMEOUT: 60000,
  CLIENT_STORAGE_NAMESPACE: 'test',
}

init

import {
  TrackerAPI,
  TrackerService,
  TrackerWS,
  ClientStorage,
} from '@strg-behave/tracking-client-lib'

const ws = new TrackerWS(config)
const storage = new ClientStorage(config)
const service = new TrackerService(ws, storage, config)
const api = new TrackerAPI(service, config)

track

The events can be send to the global namespace defined by config.NAMESPACE.

// assume global namespace is `data`
data = data || []
let event = {
  key: 'test', // required
  value: 'test', // required
  time: Date.now(), // optional
  content: 'https://www.test.at', // optional keys will be passed as plain string
}
data.push(event)

Where time and content are optional parameters, time will be set (if not provided) inside tracking service layer. The value of content will be hashed as CRC32 checksum and passed to the WebSocket when set.
