Details

This Chat-Tile Demo implements a simple chat/collaborative application fed in real-time via a Lightstreamer server. Once logged in, the user can start exchange messages with every other user present in the demo. For each user a tile of a specific background color is created, which contains the last message typed as well as the nickname chosen by the user and the user-agent information of the originating client.
User messages are broadcasted as you type, character by character, to all other users.

The demo includes the following client-side functionalities:

• A Subscription containing 1 item, subscribed to in COMMAND mode.
• The user messages are sent to the Lightstreamer Server using the LightstreamerClient.sendMessage utility.

Install

If you want to install a version of this demo pointing to your local Lightstreamer Server, follow these steps:

• As prerequisite, the Lightstreamer - Chat-Tile 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.
• Download this project.
• Get the lightstreamer.min.js file from npm or unpkg and put it in the src/js folder of the demo. Alternatively, you can generate a customized lightstreamer.min.js library containing only the classes you actually use; see the build instructions on the GitHub page. In that case, be sure to include the LightstreamerClient, Subscription, DynaGrid, and StatusWidget modules.
• Get the require.js file from requirejs.org and put it in the src/js folder of the demo.
• Get the masonry.pkgd.min.js file from Masonry - Cascading grid layout library - home page and put it in the src/js folder of the demo.
• Deploy this demo on the Lightstreamer Server (used as Web server) or in any external Web Server. If you choose the former, please note that in the <LS_HOME>/pages/demos/ folder, there may be already a ChatTileDemo folder. If this is not your case, please create the folders <LS_HOME>/pages/demos/ChatTileDemo and copy here the contents of the /src folder of this project. 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 js/lsClient.js this line:
  var lsClient = new LightstreamerClient(null,"CHATTILE");
  and change it accordingly (replace null with your server URI).
• Open your browser and point it to: http://localhost:8080/demos/ChatTileDemo/
