title: How to use Facebook Relay in a React app written in TypeScript (TSX)?
body: <p>I would like to write a new web application in <a href="https://facebook.github.io/react/" rel="nofollow">React</a> that uses <a href="https://facebook.github.io/relay/" rel="nofollow">Relay</a> to communicate with a <a href="https://facebook.github.io/graphql/" rel="nofollow">GraphQL</a> server. Recently <a href="https://github.com/Microsoft/TypeScript/wiki/JSX" rel="nofollow">JSX support</a> was introduced for <a href="http://www.typescriptlang.org/" rel="nofollow">TypeScript</a>. But there is no typings declaration file (.d.ts) for Relay on <a href="http://definitelytyped.org/" rel="nofollow">DefinitelyTyped</a>. How can I write my application in TypeScript without having to write a typings file for Relay first?</p>
