No new files are created. Fifteen existing files are updated:
Web Server Code Unique to this Chapter¶
- hlcClient.jss
- add event monitoring to client routines
- add event notification to browser via web socket. - it should be noted that this is a rough implementation for notifying the user of asynchronous events and is appropriate for a lightweight demo but inappropriate for a PoC or a production system.
Defining the business network¶
- /models/sample.CTO add events to sample.CTO file
- /lib/sample.js add event notification to transactions
Web Browser Code Unique to this Chapter¶
- all UX files Add placeholder for notification icon and add placeholder for notification counter.
- all UX javascript files use subscribe, unsubscribe and notifyMe routines
- z2b-events.js add event support for alert subscription, notification
- CSS/pageStyles.css add support for notification icon and text
