title: How to install typings for Visual Studio Code in an offline development environment?
body: <p>I'm using VisualStudio Code, and trying to enable IntelliSense.  It seems to be dependent on <code>typings</code>.  How can I install these offline?  In PowerShell, running </p>
  
  <pre><code>typings search leaflet
  </code></pre>
  
  <p>returned an error (unsurprising, because I'm offline).</p>
  
  <pre><code>Unable to connect to "https://api.typings.org/search?query=leaflet"
  </code></pre>
  
  <p>Running that web query on an online computer resulted in a difficult to read JSON file.  A further google search resulted in this likely candidate: 
  <a href="https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/leaflet/index.d.ts" rel="nofollow noreferrer">https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/leaflet/index.d.ts</a></p>
  
  <p>My question has three parts, and I'd appreciate pointers on any of these.</p>
  
  <p>1) How can I figure out what typings I need?</p>
  
  <p>2) Which files do I need to take to the offline computer?  Do I just need the d.ts file?</p>
  
  <p>2) Where should this file be installed so that VS Code can read it?</p>
