How to use refs in React with Typescript

Question

I\'m using Typescript with React. I\'m having trouble understanding how to use refs so as to get static typing and intellisense with respect to the react nodes referenced by

From React type definition

    type ReactInstance = Component | Element;
....
    refs: {
            [key: string]: ReactInstance
    };

So you can access you refs element as follow

stepInput = () => ReactDOM.findDOMNode(this.refs['stepInput']);

without redefinition of refs index.

As @manakor mentioned you can get error like

Property 'stepInput' does not exist on type '{ [key: string]: Component | Element; }

if you redefine refs(depends on IDE and ts version you use)
