I've been looking into React lately and was hoping to use JSX and typescript. I haven't been able to find any resources on this or type definitions for React.
Can you use Typescript with JSX and are type definitions available?
Yes, sure. Take a look at the React + TypeScript quick start guide .
In terms of software development, TypeScript offers many advantages over JavaScript: Optional static typing. JavaScript is a dynamically typed language, which means that types are checked, and data type errors are only detected at runtime. This can be very dangerous and can create errors during production.
The React team is currently discussing making Typescript annotations an internally used thing. This may be changing on the official for you, soon.
React jsx will be available in upcomming TypeScript 1.6. Here's more info.
François de Campredon created a type definition for React: https://github.com/fdecampredon/react-observe-todomvc/blob/typescript/src/declarations/react.d.ts
It does not support JSX obviously, since it is another language with a syntax different from TypeScript.
