Realtime Services
An API reference guide to the realtime services
Introduction
OpenDataDSL allows you to listen to server-side events that you can use to trigger client-side actions such as:
- Update the view in a GUI
- Run a local process
It uses SignalR which is a free and open-source library available from Microsoft which is used for building real-time web applications.
