  <p>here is my tsconfig.json file:</p>
  
  <pre><code>{
    "compilerOptions": {
      "declaration": false,
      "emitDecoratorMetadata": true,
      "experimentalDecorators": true,
      "lib": ["es6", "dom"],
      "mapRoot": "./",
      "module": "es6",
      "moduleResolution": "node",
      "outDir": "../dist/out-tsc",
      "sourceMap": true,
      "target": "es5",
      "typeRoots": [
        "../node_modules/@types"
      ],
      "types": [
        "jasmine"
      ]
    }
  }
  </code></pre>
