title: NPM Package doesn't have Types
body: <p>I'm transforming a small express api to use TypeScript, but some of the packages don't have a <code>@types/</code> so when I import them I get a <code>TS2307</code> error. </p>
  
  <p>Is there something I can do to resolve the error? Or maybe type it myself, depending on the package complexity. One example is <code>express-bearer-token</code><a href="https://github.com/tkellen/js-express-bearer-token" rel="nofollow noreferrer">(found here)</a></p>
