Lightstreamer-example-HelloWorld-client-javascript | Hello World tutorial for Lightstreamer

If you want to install a version of this demo pointing to your local Lightstreamer Server, follow these steps:.
As prerequisite, the Lightstreamer - "Hello World" Tutorial - 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.
Download this project.
Get the lightstreamer.min.js file from npm or unpkg.
Deploy this demo on the Lightstreamer Server used as Web server: create the folders <LS_HOME>/pages/HelloWorld and copy here the contents of the /src folder of this project. Note. If we use the Lightstreamer Server as a Web server, both the static resources and the real-time data will be delivered by the Lightstreamer Server. But the typical production architecture has an external Web server (whatever it is), in addition to the Lightstreamer Server. Everything is downloaded from the Web server except for the real-time data, which comes from the Lightstreamer Server. This separation improves both flexibility (you are free to use whatever Web/application server you want) and performance (you can isolate the power-demanding real-time connections to a separate box, without impacting your existing Web infrastructure).
The client demo configuration assumes that Lightstreamer Server, Lightstreamer Adapters, and this client are launched on the same machine. If you need to target a different Lightstreamer server, please search in index.html this line: var client = new LightstreamerClient(null,"HELLOWORLD"); and change it accordingly.
