Usage
There are several ways to create your typings repository:
Here are examples to create npm-noop2
# create the github repo from github website
# under your organization folder (e.g. /somewhere/typed-typings/)
yo typings npm-noop2
# Once it is done,
cd npm-noop2
# create the github repo from github website
# clone it locally to your machine (e.g. into /somewhere/typed-typings/npm-noop2/)
# in that directory:
yo typings
# create the github repo from github website
# under your organization folder (e.g. /somewhere/typed-typings/)
mkdir npm-noop2 && cd npm-noop2
yo typings
How to write typings

About writing tests for typings
Simply shape test (like those in DefinitlyType) is not sufficient. Since there is no type in javascript, even if you create a wrong signature, you won't detect it until runtime.
e.g.
// source code
function foo(something) {
return something++;
}
The source code expects something
to be a number. If you write your typings as:
function foo(something: string): string;
It won't fail until you use it. i.e.
// consumer program
import foo ....somehow
let x = "abc";
foo(x);
Because your typings provide guidance to the consumer, they will write their code that way and will fail when they run it.
tsc
will compile fine.
