Importing QuaggaJS into Angular 2 project

Question

I'm trying to use QuaggaJS in Angular 2. The project uses routes so when the add page is clicked on, QuaggaJS should load the Javascript files as below:

<script src="vendor/jquery-1.9.0.min.js" type="text/javascript"></script>
<script src="../dist/quagga.js" type="text/javascript"></script>
<script src="live_w_locator.js" type="text/javascript"></script>

However, these don't load. There is a provided quagga.d.ts file that allows use of the QuaggaJS API, but I'm not sure how to use it.

Do the Javascript files need to be imported into the project as it is for typescript components?

Component file:

ngOnInit() {
    console.log(this);
    let state = {
      inputStream: {
        type : "LiveStream",
        constraints: {
          width: {min: 640},
          height: {min: 480},
          facingMode: "environment",
          aspectRatio: {min: 1, max: 2}
        }
      },
      locator: {
        patchSize: "medium",
        halfSample: true
      },
      numOfWorkers: 4,
      decoder: {
        readers : [{
          format: "code_128_reader",
          config: {}
        }]
      },
      locate: true
    };

    Quagga.init(state, (err) => {
      if (err) {
        return console.log(err);
      }

      Quagga.start();
    });

    Quagga.onProcessed(this.onProcessed);

    Quagga.onDetected(this.logCode);

  }

  onProcessed(result: any) {
    var drawingCtx = Quagga.canvas.ctx.overlay,
    drawingCanvas = Quagga.canvas.dom.overlay;

    if (result) {
      if (result.boxes) {
        drawingCtx.clearRect(0, 0, parseInt(drawingCanvas.getAttribute("width")), parseInt(drawingCanvas.getAttribute("height")));
        result.boxes.filter(function (box) {
          return box !== result.box;
        }).forEach(function (box) {
          Quagga.ImageDebug.drawPath(box, {x: 0, y: 1}, drawingCtx, {color: "green", lineWidth: 2});
        });
      }

      if (result.box) {
        Quagga.ImageDebug.drawPath(result.box, {x: 0, y: 1}, drawingCtx, {color: "#00F", lineWidth: 2});
      }

      if (result.codeResult && result.codeResult.code) {
        Quagga.ImageDebug.drawPath(result.line, {x: 'x', y: 'y'}, drawingCtx, {color: 'red', lineWidth: 3});
      }
    }
  }

  logCode(result) {
    this.lastResult = result.codeResult.code;
    console.log(this);
  }
