This guide shows you how to migrate to the new rendering methods for the Route class.
In the Directions service (Legacy), the rendering methods were part of the
`DirectionsRenderer` class. The Route class provides two new rendering
methods: `createPolylines` and `createWaypointAdvancedMarkers`.

## Legacy `DirectionsRenderer`

In the Directions service (Legacy), the rendering methods were part of the
`DirectionsRenderer` class. The `DirectionsRenderer` class handles
display of the polyline, any associated markers, as well as the textual display of steps; it
has the following methods:

- `setDirections()` - Renders the provided directions response.
- `setMap()` - Sets the map on which to render the directions response.
- `setPanel()` - Displays the directions as a series of textual steps in a panel.

The following example shows how to use the `DirectionsRenderer` class to render
directions on a map.

```javascript
function initMap() {
  var directionsService = new google.maps.DirectionsService();
  var directionsRenderer = new google.maps.DirectionsRenderer();
  var chicago = new google.maps.LatLng(41.850033, -87.6500523);
  var mapOptions = {
    zoom:7,
    center: chicago
  }
  var map = new google.maps.Map(document.getElementById('map'), mapOptions);
  // Set the map on the directions renderer.
  directionsRenderer.setMap(map);
  // Set the panel to display the directions as a series of textual steps.
  directionsRenderer.setPanel(document.getElementById('directionsPanel'));
}

function calcRoute() {
  var start = document.getElementById('start').value;
  var end = document.getElementById('end').value;
  var request = {
    origin: start,
    destination: end,
    travelMode: 'DRIVING'
  };
  // Call the directions service to get the directions.
  directionsService.route(request, function(response, status) {
    if (status == 'OK') {
      // Render the polyline and markers on the map.
      directionsRenderer.setDirections(response);
    }
  });
}
    
```

## `Route` class

The Route class provides the following new rendering methods, which replace the
legacy `DirectionsRenderer` class methods:

- `createPolylines`
- `createWaypointAdvancedMarkers`

The `Route` class has no equivalent to the `setPanel()` method in the
legacy `DirectionsRenderer` class. To display the textual steps, you must
manually create the HTML elements and insert them into the DOM. The following example
shows how to render directions on a map using the Route class, and manually create the
HTML elements to display the textual steps.

```javascript
let map;
let mapPolylines = [];
let markers = [];
let center = { lat: 37.447646, lng: -122.113878 }; // Palo Alto, CA

// Initialize and add the map.
async function initMap() {
  // Request the needed libraries.
  const { Map } = await google.maps.importLibrary('maps');
  const { Route } = await google.maps.importLibrary('routes');

  map = new Map(document.getElementById("map"), {
    zoom: 12,
    center,
    mapTypeControl: false,
    mapId: 'DEMO_MAP_ID',
  });

  // Define a simple directions request.
  const request = {
    origin: 'Mountain View, CA',
    destination: 'San Francisco, CA',
    travelMode: 'DRIVING',
    fields: ['legs'],
  };

  // Call computeRoutes to get the directions.
  const { routes } = await Route.computeRoutes(request);

  // Use createPolylines to create polylines for the route.
  mapPolylines = routes[0].createPolylines();
  // Add polylines to the map.
  mapPolylines.forEach((polyline) => polyline.setMap(map));
  fitMapToPath(routes[0].path);

  // Add markers to start and end points.
  const markers = await routes[0].createWaypointAdvancedMarkers({map});

  // Render navigation instructions.
  const directionsPanel = document.getElementById("directions-panel");

  if (!routes || routes.length === 0) {
    if (directionsPanel) {
      directionsPanel.textContent = "No routes available.";
    }
  }

  const route = routes[0];
  if (!route.legs || route.legs.length === 0) {
    if (directionsPanel) {
      directionsPanel.textContent = "The route has no legs.";
    }
    return;
  }

  const fragment = document.createDocumentFragment();

  route.legs.forEach((leg, index) => {
    const legContainer = document.createElement("div");
    legContainer.className = "directions-leg";
    legContainer.setAttribute("aria-label", `Leg ${index + 1}`);

    // Leg Title
    const legTitleElement = document.createElement("h3");
    legTitleElement.textContent = `Leg ${index + 1} of ${route.legs.length}`;
    legContainer.appendChild(legTitleElement);

    if (leg.steps && leg.steps.length > 0) {
      // Add steps to an ordered list
      const stepsList = document.createElement("ol");
      stepsList.className = "directions-steps";

      leg.steps.forEach((step, stepIndex) => {
        const stepItem = document.createElement("li");
        stepItem.className = "direction-step";
        stepItem.setAttribute("aria-label", `Step ${stepIndex + 1}`);

        // Maneuver
        if (step.maneuver) {
          const maneuverNode = document.createElement("p");
          maneuverNode.textContent = step.maneuver;
          maneuverNode.className = "maneuver";
          stepItem.appendChild(maneuverNode);
        }

        // Distance and Duration
        if (step.localizedValues) {
          const distanceNode = document.createElement("p");
          distanceNode.textContent = `${step.localizedValues.distance} (${step.localizedValues.staticDuration})`;
          distanceNode.className = "distance";
          stepItem.appendChild(distanceNode);
        }

        // Instructions
        if (step.instructions) {
          const instructionsNode = document.createElement("p");
          instructionsNode.textContent = step.instructions;
          instructionsNode.className = "instruction";
          stepItem.appendChild(instructionsNode);
        }

        stepsList.appendChild(stepItem);
      });
      legContainer.appendChild(stepsList);
    }

    fragment.appendChild(legContainer);
    directionsPanel?.appendChild(fragment);
  });
}

// Helper function to fit the map to the path.
async function fitMapToPath(path) {
  const { LatLngBounds } = await google.maps.importLibrary('core');
  const bounds = new LatLngBounds();
  path.forEach((point) => {
    bounds.extend(point);
  });
  map.fitBounds(bounds);
}

initMap();
    
```
