Write TypeScript declaration file for callable module

The cldr-data package is defined something like:

function cldrData(path) {
  // ...
}

cldrData.all = function() {
  // ...
}

cldrData.entireMainFor = function(locale/*, ...*/) {
  // ...
}

cldrData.entireSupplemental = function() {
  // ...
}

module.exports = cldrData;

How should I write a type declaration file for such a package?

This seems to work:

declare module 'cldr-data' {
    interface CldrData {
        (path: any, ...args: any[]): any;
        availableLocales: any;
        all(): any;
        entireMainFor(locale: any, ...args: any[]): any;
        entireSupplemental(): any;
    }

    declare const cldrData: CldrData;
    export = cldrData;
};

Usage:

import cldrData from 'cldr-data';

cldrData('main/en/numbers');
cldrData.entireSupplemental();
cldrData.entireMainFor('en');
console.log(cldrData.all());
