How to define a Module that is a function in Typescript

I'm looking for a way to write a valid definition file for debug

In JS you call:

var debug = require('debug')('http')

Then you use it like:

debug('my debug message');

I have no clue how to define my debug.d.ts to support that pattern. Any help is wellcome.

Thanks

For use in TypeScript you'll have to separate out the call into two parts like so:

import debugMod = require('debug');
var debug = debugMod('http');

The definition file (debug.d.ts) would look like this:

declare module "debug" {
    function dbg(s:string):(s:string) => void;

    export = dbg;
}
