title: How to ignore `node_modules` folder during TypeScript build in VSCode
body: <p>I'm using visual studio code IDE and typescript, how do I get it to ignore the node_modules folder during build?  Or have it build <code>.ts</code> files on save?  It is showing a lot of errors because it's trying to compile node_modules tsd.</p>
  
  <p>Currently my tasks.json is</p>
  
  <pre><code>{
      "version": "0.1.0",
  
      // The command is tsc.
      "command": "tsc",
  
      // Show the output window only if unrecognized errors occur. 
      "showOutput": "silent",
  
      // Under windows use tsc.exe. This ensures we don't need a shell.
      "windows": {
          "command": "tsc.exe"
      },
  
      "isShellCommand": true,
  
      // args is the HelloWorld program to compile.
      "args": [],
  
  
  
      // use the standard tsc problem matcher to find compile problems
      // in the output.
      "problemMatcher": "$tsc"
  }
  </code></pre>
