Lightstreamer - Basic Stock-List Demo - HTML (React) Client
This 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.
Each row in the table is implemented as an instance of a React class. The state of these instances is then refreshed through the onItemUpdate callback implementation called by an associated Lightstreamer Subscription; check the Stock.js class to see how this is done.
The demo includes the following client-side functionalities:
- A Subscription containing 10 items, subscribed to in MERGE mode.
You will notice that in the sources of this demo there is a jsx folder. This folder contains classes in the jsx format that are then transformed into plain js by Babel and copied into the js folder. When modifying this demo you can either act on the jsx version of these classes or on the js version. If you choose to edit the jsx files you will have to keep them aligned with the js folder using the aforementioned Babel:
npm install -g babel
Automatically convert the jsx file to js whenever a change is made
babel --watch src/jsx --out-dir src/js
If you want to install a version of this demo pointing to your local Lightstreamer Server, follow these steps:
- Note that, as prerequisite, the Lightstreamer - Stock- List Demo - Java Adapter has to be deployed on your local Lightstreamer Server instance. Please check out that project and follow the installation instructions provided with it, then launch the server.
- Deploy this demo on the Lightstreamer Server (used as Web server) or in any external Web Server: copy there the contents of the
/srcfolder of this project. The client demo configuration assumes that Lightstreamer Server and this client are launched on the same machine. If you need to target a different Lightstreamer server, please open the
src/js/Constants.jsand configure the SERVER element accordingly.
- Lightstreamer JS client, RequireJS and React are currently hot-linked in the html page: you may want to replace them with a local version and/or to upgrade their version.
- Open your browser and point it to to the newly deployed folder.
