Search for an address

Learn how to search for an address.

Find the location of addresses with the geocoding service using API key authentication

The ArcGIS Geocoding service allows to search for an address or a place, find candidate matches, and return complete addresses with a location.

In this tutorial, use the MapLibre ArcGIS plugin to display a map and ArcGIS REST JS to access the Geocoding service. Use a simple input control to accept text and a button to execute a search for an address or place. When an address or place is located, a pop-up will appear with the name, location, and address, and the view will pan to it.

Prerequisites

You need an ArcGIS Location Platform or ArcGIS Online account.

Steps

Get the starter app

Select a type of authentication below and follow the steps to create a new application.

You can choose one of the following to create a new CodePen:

Option 1: Complete the Display a map tutorial; or,
Option 2: Start from the Display a map tutorial .

Set up authentication

Create developer credentials in your portal for the type of authentication you selected.

Create a new API key credential with the correct privileges to access the resources used in this tutorial.

Go to the Create an API key tutorial to follow the steps to get an access token with these privilege(s):
- Privileges
  - Location services > Basemaps
  - Location services > Geocoding

Set developer credentials

Use the API key or OAuth developer credentials so your application can access ArcGIS services.

Update the accessToken variable to use your API key.

Use dark colors for code blocks
    /* Use for API key authentication */
    const accessToken = "YOUR_ACCESS_TOKEN";

In both the index.html and callback.html files, replace YOUR_CLIENT_ID and YOUR_REDIRECT_URL with the client ID and redirect URL of your OAuth credentials.

index.html
Use dark colors for code blocks
    /* Use for user authentication */
    const clientId = "YOUR_CLIENT_ID"; // Your client ID from OAuth credentials
    const redirectUri = "YOUR_REDIRECT_URI"; // The redirect URL registered in your OAuth credentials
    const session = await arcgisRest.ArcGISIdentityManager.beginOAuth2({
        clientId,
        redirectUri,
        portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    });

    const accessToken = session.token;

callback.html
Use dark colors for code blocks
    arcgisRest.ArcGISIdentityManager.completeOAuth2({
      clientId: "YOUR_CLIENT_ID", // Your client ID from OAuth credentials
      redirectUri: "YOUR_REDIRECT_URI", // The redirect URL registered in your OAuth credentials
      portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    });

Run the app and ensure you can sign in successfully.

If you are unable to sign in, make sure you have the correct redirect URL and port. This URL varies based on your application and typically takes the format of https://<server>[:port]/callback.html or http://my-arcgis-app:/auth. For example, if you are running an application on http://127.0.0.1:5500/, set http://127.0.0.1:5500/callback.html as your redirect URL in the index.html and callback.html file and your developer credential. They all have to match!

Add references to ArcGIS REST JS

This tutorial uses ArcGIS REST JS to access the geocoding service.

In the <head> element, add references to the ArcGIS REST JS request and geocoding libraries.

Update the map

An arcgis/navigation basemap style is typically used in geocoding and routing applications. Update the basemap layer to use the style.

Update the basemap and the map initialization to center on location [151.2093, -33.8688], Sydney.

    });

    const basemapStyle = maplibreArcGIS.BasemapStyle.applyStyle(map, {
      style: 'arcgis/navigation',
      token: accessToken
    });

Create geocoder controls

Use an HTML <input> control to type an address into, and a <button> control to initiate the query. Wrap them in a <div>.

To add the <div> element as a Map control, you create an object that implements the MapLibre GL JS IControl interface.

Create a GeocodeControl class with an onAdd function. Inside, create a <div> element with an <input> and a <button> inside. You can use document.createElement to create a template with this HTML inside. Return this element.

Call the geocoding service

When you click the button, call arcgisRest.geocode with the value of the search query. This uses the findAddressCandidates operation in the geocoding service.

For more control over geocoding, you can pass an IGeocodeOptions instead of a simple string.

Attach a click event handler to the button.

    const geocodeControl = new GeocodeControl();

    document.getElementById("geocode-button").addEventListener("click", () => {

    });
Expand

Inside the click handler, create a new arcgisRest.ApiKeyManager to access the geocoding service. Call arcgisRest.geocode with the user's search query. Set the params to include the center of the map and set outFields to * to return all fields.

      arcgisRest
        .geocode({
          singleLine: query,
          authentication,
          params: {
            location: map.getCenter().toArray().join(","), // center of map as longitude,latitude
            outFields: "*" // return all fields
          }
        })

    });
Expand

Show the result

If the query is successful, the candidates property will contain at least one value. To display the first candidate on the map, create a pop-up and add it to the map.

Add a response handler. Inside, check that candidates contains at least one value. Use the location property to add a popup to the map and set the HTML of the popup to LongLabel to display the full address.

To add a popup to the map, you use the Popup class in MapLibre GL JS. See the Display a pop-up tutorial for more information.

            location: map.getCenter().toArray().join(","), // center of map as longitude,latitude
            outFields: "*" // return all fields
          }
        })

        .then((response) => {

          const result = response.candidates[0];
          if (!result) {
            alert("That query didn't match any geocoding results.");
            return;
          }
          const lngLat = [result.location.x, result.location.y];

          new maplibregl.Popup().setLngLat(lngLat).setHTML(result.attributes.LongLabel).addTo(map);

        })
Expand

Use MapLibre GL JS's panTo method to center the map at the result.

This transitions the map smoothly from the current location to the result. To instantly reposition the map to that location, you could use jumpTo instead.

Handle errors

It is good practice to handle situations where there is a problem accessing the service. This could happen due to network disruption or a problem with your API key, for instance.

Check for issues accessing the geocoding service and alert the user.

        })

        .catch((error) => {
          alert("There was a problem using the geocoder. See the console for details.");
          console.error(error);
        });

Run the app

Run the app.

In the input box, type "1 King St." or "Starbucks" and then click the Geocode button to find its location. If a location is found, the map will zoom to it and display a pop-up with the address.
