change log:

1. Update link to match current Elektron WebSocket API page
2. Update JSON message to match ADS3.2 rrg version format
3. Update the application to use express.js simple web server, do not need to deploy in other web server anymore

 # Elecktron WebSocket API with TypeScript Example
 ## Overview
 
-[Elektron WebSocket API](https://developers.thomsonreuters.com/elektron/websocket-api-early-access) enables easy integration into a multitude of client technology environments such as scripting and web.  This API runs directly on your TREP infrastructure or the Thomson Reuters platform and presents data in an open (JSON) readable format. The API supports all Thomson Reuters Elektron data models and can be integrated into multiple client technology standards e.g. Python, R, .Net etc.

 [TypeScript](https://www.typescriptlang.org) programming language is a typed superset of JavaScript that compiles to readable, standards-based JavaScript. The language is designed for application-scale JavaScript by adding optional types, classes, modules, ECMAScript 2015 features and future proposals to JavaScript. TypeScript supports tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript is as a first-class programming language in Microsoft Visual Studio, [Angular](https://angularjs.org/) web application platform. It also supported by various application frameworks like [React](https://github.com/Microsoft/TypeScript-React-Starter#typescript-react-starter), [NodeJS and Express framework](https://github.com/Microsoft/TypeScript-Node-Starter#typescript-node-starter), [ASP.Net Core](https://www.typescriptlang.org/docs/handbook/asp-net-core.html), [Vue.js](https://github.com/Microsoft/TypeScript-Vue-Starter#typescript-vue-starter) and more. 
 
 This example shows how to implement the Elektron WebSocket API JavaScript web application with TypeScript. The web application source codes are implemented in TypeScript language to connect, consume and display data from the ADS server via the Elektron WebSocket API in the web browsers. All source codes will be compiled to readable JavaScript with [Webpack](https://webpack.js.org/) JavaScript module bundler.
 
+*Note: The initial release of this API is for deployed TREP customers only (i.e. to use it you will need an installed version of TREP 3.2).
