A simple stocklist demo application showing integration between React and the Lightstreamer JavaScript Client library.
View live demoThis demo displays real-time market data for ten stocks, generated by a feed simulator in a similar way to the Lightstreamer - Basic Stock-List Demo - HTML Client.
This page uses the JavaScript Client API for Lightstreamer to handle the communications with Lightstreamer Server and uses React to display the real-time data pushed by Lightstreamer Server.
A Lightstreamer Subscription is used for subscribing to the data. The onItemUpdate callback implementation fills an object that is used by React to populate the HTML.
The demo includes the following client-side functionalities:
- A Subscription containing 10 items, subscribed to in MERGE mode.
