This is the documentation for the React Native module. Before integrating, read the native SDK documentation to familiarize yourself with the platform.
Install the package from npm:
If you are using Expo, you must eject:
On iOS, you must add location usage descriptions and background modes to your
Info.plist, then add the SDK to your project, preferably using CocoaPods. Finally, initialize the SDK in
AppDelegate.m, passing in your Radar publishable API key:
On Android, you must add the Google Play Services library to your project, then add the SDK to your project, preferably using Gradle. Finally, initialize the SDK in
MainApplication.java, passing in your Radar publishable API key:
First, import the module:
To identify the user when logged in, call:
userId is a stable unique ID for the user.
To set an optional dictionary of custom metadata for the user, call:
metadata is a JSON object with up to 16 keys and values of type string, boolean, or number.
Finally, to set an optional description for the user, displayed in the dashboard, call:
description is a string.
You only need to call these functions once, as these settings will be persisted across app sessions.
Before tracking the user's location, the user must have granted location permissions for the app.
To determine the whether user has granted location permissions for the app, call:
status will be a string, one of:
To request location permissions for the app, call:
background is a boolean indicating whether to request background location permissions or foreground location permissions.
Once you have initialized the SDK and the user has granted permissions, you can track the user's location.
To track the user's location in the foreground, call:
err will be a string, one of:
ERROR_PUBLISHABLE_KEY: SDK not initialized
ERROR_PERMISSIONS: location permissions not granted
ERROR_LOCATION: location services error or timeout (10 seconds)
ERROR_NETWORK: network error or timeout (10 seconds)
ERROR_BAD_REQUEST: bad request (missing or invalid params)
ERROR_UNAUTHORIZED: unauthorized (invalid API key)
ERROR_PAYMENT_REQUIRED: payment required (organization disabled or usage exceeded)
ERROR_FORBIDDEN: forbidden (insufficient permissions or no beta access)
ERROR_NOT_FOUND: not found
ERROR_RATE_LIMIT: too many requests (rate limit exceeded)
ERROR_SERVER: internal server error
ERROR_UNKNOWN: unknown error
Once you have initialized the SDK and the user has granted permissions, you can start tracking the user's location in the background.
For background tracking, the SDK supports custom tracking options as well as three presets:
EFFICIENT: A low frequency of location updates and lowest battery usage. On Android, avoids Android vitals bad behavior thresholds.
RESPONSIVE: A medium frequency of location updates and low battery usage. Suitable for most consumer use cases.
CONTINUOUS: A high frequency of location updates and higher battery usage. Suitable for on-demand use cases (e.g., delivery tracking) and some consumer use cases (e.g., order ahead, "mall mode").
To start tracking the user's location in the background, call one of:
You only need to call these methods once, as these settings will be persisted across app sessions.
Though we recommend using presets for most use cases, you can customize the tracking options. See the tracking options reference.
To stop tracking the user's location in the background (e.g., when the user logs out), call:
To listen for events, location updates, and errors, you can add event listeners:
Add event listeners outside of your component lifecycle (e.g., outside of
componentDidMount) if you want them to work when the app is in the background.
You can also remove event listeners:
launchOptions for the
You can manually update the user's location by calling:
The React Native module also exposes APIs for anonymous context, geocoding, search, and distance.
Get a single location update without sending it to the server:
With the context API, get context for a location without sending device or user identifiers to the server:
With the forward geocoding API, geocode an address, converting address to coordinates:
With the reverse geocoding API, reverse geocode a location, converting coordinates to address:
With the IP geocoding API, geocode the device's current IP address, converting IP address to city, state, and country:
With the autocomplete API, autocomplete partial addresses and place names, sorted by relevance:
With the geofence search API, search for geofences near a location, sorted by distance:
With the places search API, search for places near a location, sorted by distance:
With the distance API, calculate the travel distance and duration from an origin to a destination:
With the matrix API, calculate the travel distance and duration between multiple origins and destinations for up to 25 routes:
