Find a route and directions
Learn how to find a route and directions with the route service.
Routing is the process of finding the path from an origin to a destination in a street network. You can use the Routing service to find routes, get driving directions, calculate drive times, and solve complicated, multiple vehicle routing problems. To create a route, you typically define a set of stops (origin and one or more destinations) and use the service to find a route with directions. You can also use a number of additional parameters such as barriers and mode of travel to refine the results.
In this tutorial, you define an origin and destination by clicking on the map. These values are used to get a route and directions from the route service. The directions are also displayed on the map.
Prerequisites
You need a free ArcGIS developer account to access your dashboard and API keys. The API key must be scoped to access the services used in this tutorial.
Steps
Create a new pen
- To get started, either complete the Display a map tutorial or .
Set the API key
To access ArcGIS services, you need an API key.
Go to your dashboard to get an API key.
In CodePen, set the
apiKeyto your key, so it can be used to access basemap layer and location services.Change line 1 2 3 4esriConfig.apiKey = "YOUR-API-KEY"; const map = new Map({ basemap: "arcgis-topographic" //Basemap layer service });
Add modules
In the
requirestatement, add theGraphic,RouteTask,RouteParameters, andFeatureSetmodules.The ArcGIS API for JavaScript uses AMD modules. The
requirefunction is used to load modules so they can be used in the mainfunction. It's important to keep the module references and function parameters in the same order.Add line. Add line. Add line.

Update the map
A streets basemap layer is typically used in routing applications. Update the basemap property to use the arcgis-navigation basemap layer and change the position of the map to center on Los Angeles.

Execute the route task
To execute the task, add the origin and destination graphics to the stops parameter as a FeatureSet and then execute the task. The resulting route will be added to the map as a Graphic.
Input parameters are necessary to execute the route task. While there are many parameters you can add, such as stops and barriers, at minimum you need to provide an origin and destination point.
