title: How to configure VS Code's "tasks.json" to build all .ts files
body: <p>Its possible this has been asked before if so I am sorry for the duplicate post simply redirect me to the other thread.</p>
  
  <p>Is it possible to configure VS Code's <strong>"tasks.json"</strong> to <strong>compile all .ts files in the folder</strong>. I know I can add the path to the .ts file manually like this:</p>
  
  <pre><code>"args": [ HelloWorld.ts ],
  </code></pre>
  
  <p>and it does compile the HelloWorld.ts correctly but I cannot figure out how to setup the tasks.json that all.ts files in the folder are compiled.</p>
  
  <p>I have looked at some tutorials which all suggest to simply remove the "HelloWorld.ts" but that does not work as no .ts files are compiled at all.</p>
  
  <p>Here is the entire tasks.json file that I have in VS Code:</p>
  
  <pre><code>{
      "version": "0.1.0",
  
      // The command is tsc. Assumes that tsc has been installed using npm install -g typescript
      "command": "tsc",
  
      // The command is a shell script
      "isShellCommand": true,
  
      // Show the output window only if unrecognized errors occur.
      "showOutput": "always",
  
      // args is the HelloWorld program to compile.
      "args": [ "HelloWorld.ts" ],
  
      // use the standard tsc problem matcher to find compile problems
      // in the output.
      "problemMatcher": "$tsc"
  }
  </code></pre>
