TypeScript and Socket.io

Question

I would like to use socket.io in my Typescript project, but I\'ve only found .d.ts files for server-side typescript.

This is a nice example: https://github.com/soywiz/ty

I created my own .d.ts file, it's rather short but it works well:

declare var io : {
    connect(url: string): Socket;
};
interface Socket {
    on(event: string, callback: (data: any) => void );
    emit(event: string, data: any);
}

This declaration file can be imported to client side Typescript and the socket.io standard example will work, here's my Typescript version:

var socket=io.connect("localhost");
socket.on("news",(data:any)=>alert(data));
socket.emit("news","hello");
