# Location Sharing
Location sharing allows users to send a static position or share their real-time location with other participants in a channel. Stream Chat supports both static and live location sharing.
There are two types of location sharing:
- **Static Location**: A one-time location share that does not update over time.
- **Live Location**: A real-time location sharing that updates over time.
The SDK handles location message creation and updates, but location tracking must be implemented by the application using device location services.
## Enabling location sharing
The location sharing feature must be activated at the channel level before it can be used. You have two configuration options: activate it for a single channel using configuration overrides, or enable it globally for all channels of a particular type via [channel type settings](/chat/docs//channel_features/).
```javascript
// Enabling it for a channel
await channel.updatePartial({
set: {
config_overrides: {
shared_locations: true,
},
},
});
// Enabling it for a channel type
const update = await client.updateChannelType("messaging", {
shared_locations: true,
});
```
```python
# Enabling it for a channel type
client.update_channel_type(
"messaging",
shared_locations=True,
)
```
```ruby
# Enabling it for a channel type
client.update_channel_type(
"messaging",
shared_locations: true,
)
```
```php
// Enabling it for a channel type
$client->updateChannelType('messaging', [
'shared_locations' => true
]);
```
```java
// Enabling it for a channel type
ChannelType.update("messaging")
.sharedLocations(true)
.request();
```
```csharp
// Enabling it for a channel type
await channelTypeClient.UpdateChannelTypeAsync("messaging", new ChannelTypeWithStringCommandsRequest
{
SharedLocations = true
});
```
```go
// Enabling it for a channel type
client.UpdateChannelType("messaging", map[string]interface{}{
"shared_locations": true,
})
```
## Sending static location
Static location sharing allows you to send a message containing a static location.
```swift
/// Get a channel controller for the channel.
let channelController = chatClient.channelController(for: ChannelId(type: .messaging, id: "general"))
/// Send a message with a static location.
let location = LocationInfo(latitude: 10, longitude: 10)
channelController.sendStaticLocation(location)
/// Alternatively, you can use the create new message with a `NewLocationInfo` object and endAt as nil.
let newLocation = NewLocationInfo(latitude: 10, longitude: 10, endAt: nil)
let message = channelController.createNewMessage(text: "", location: newLocation)
```
```javascript
const channel = client.channel("type", "id");
// Send a message with a static location.
channel.sendSharedLocation({
created_by_device_id: "device-id",
latitude: 10,
longitude: 10,
message_id: "message-id",
});
```
```kotlin
// Send a static location message.
chatClient.sendStaticLocation(
cid = "channelType:channelId",
latitude = -8.0421,
longitude = -34.9351,
deviceId = "my-device-id",
).enqueue { /* ... */ }
```
```go
channel := chatClient.CreateChannelWithMembers(ctx, "messaging", channelID, userID)
// Create a SharedLocation Object
location := &SharedLocation{
Longitude: &longitude,
Latitude: &latitude,
CreatedByDeviceID: "test-device",
}
// Send a message with the SharedLocation object
message := channel.SendMessage(ctx, &Message{
ShareSharedLocation: location,
})
```
```java
// Create shared location request
SharedLocationRequest locationRequest = new SharedLocation.SharedLocationRequest();
locationRequest.setCreatedByDeviceId(deviceId);
locationRequest.setLatitude(latitude);
locationRequest.setLongitude(longitude);
// Convert request to SharedLocation
SharedLocation sharedLocation = new SharedLocation();
sharedLocation.setCreatedByDeviceId(locationRequest.getCreatedByDeviceId());
sharedLocation.setLatitude(locationRequest.getLatitude());
sharedLocation.setLongitude(locationRequest.getLongitude());
// Send message with shared location
MessageRequestObject messageRequest =
MessageRequestObject.builder()
.sharedLocation(sharedLocation)
.build();
Message message =
Message.send(testChannel.getType(), testChannel.getId())
.message(messageRequest)
.request()
.getMessage();
```
```ruby
@location_channel = @client.channel('messaging', channel_id: SecureRandom.uuid)
location = {
created_by_device_id: "test-device",
latitude: 40.7128,
longitude: -74.0060,
}
response = @location_channel.send_message({
shared_location: location
})
```
```csharp
var channel = await CreateChannelAsync(createdByUserId: _user1.Id, members: new[] { _user1.Id });
// Create a shared location for the initial message
var location = new SharedLocationRequest
{
Longitude = longitude,
Latitude = latitude,
EndAt = null, // null for static location
CreatedByDeviceId = "test-device",
};
// Send a message with shared location
var messageRequest = new MessageRequest
{
Text = "Test message for shared location",
SharedLocation = location,
};
var messageResp = await _messageClient.SendMessageAsync(
channel.Type,
channel.Id,
messageRequest,
_user1.Id);
```
```python
# Send a static location message
now = datetime.datetime.now(datetime.timezone.utc)
shared_location = {
"created_by_device_id": "test_device_id",
"latitude": 37.7749,
"longitude": -122.4194,
# No 'end_at' for static location
}
channel.send_message(
{"text": "Message with static location", "shared_location": shared_location},
user_id,
)
```
```php
// Send a static location message
$sharedLocation = [
'created_by_device_id' => 'test_device_id',
'latitude' => 37.7749,
'longitude' => -122.4194,
// No 'end_at' for static location
];
$channel->sendMessage(
['text' => 'Message with static location', 'shared_location' => $sharedLocation],
$userId
);
```
```dart
final locationCoordinates = LocationCoordinates(
latitude: 37.7749,
longitude: -122.4194,
);
// Send a static location message.
final response = await channel.sendStaticLocation(
location: locationCoordinates,
createdByDeviceId: 'test_device_id', // Optional
);
```
## Starting live location sharing
Live location sharing enables real-time location updates for a specified duration. The SDK manages the location message lifecycle, but your application is responsible for providing location updates.
```swift
/// Get a channel controller for the channel.
let channelController = chatClient.channelController(for: ChannelId(type: .messaging, id: "general"))
/// Send a message with a live location with the initial coordinates.
let location = LocationInfo(latitude: 10, longitude: 10)
channelController.startLiveLocationSharing(location)
/// Alternatively, you can use the create new message with a `NewLocationInfo` object and endAt non-nil.
let oneMinuteFromNow = Date().addingTimeInterval(60)
let newLocation = NewLocationInfo(latitude: 10, longitude: 10, endAt: oneMinuteFromNow)
let message = channelController.createNewMessage(text: "", location: newLocation)
```
```javascript
const channel = client.channel("type", "id");
// Send a message with a live location.
// Live location differs from the static location by the termination timestamp end_at.
channel.sendSharedLocation({
created_by_device_id: "device-id",
end_at: "2225-07-22T09:30:12.507Z",
latitude: 10,
longitude: 10,
message_id: "message-id",
});
```
```kotlin
// Start a live location sharing and automatically stops after 10 minutes.
val tenMinutesFromNow = Date().apply { time += 10.minutes.inWholeMilliseconds }
chatClient.startLiveLocationSharing(
cid = "channelType:channelId",
latitude = -8.0421,
longitude = -34.9351,
deviceId = "my-device-id",
endAt = tenMinutesFromNow,
).enqueue { /* ... */ }
```
```go
channel := chatClient.CreateChannelWithMembers(ctx, "messaging", channelID, userID)
// Create a SharedLocation Object with end_at
end_at := time.Now().Add(1 * time.Hour)
location := &SharedLocation{
Longitude: &longitude,
Latitude: &latitude,
EndAt: &end_at,
CreatedByDeviceID: "test-device",
}
// Send a message with the SharedLocation object
message := channel.SendMessage(ctx, &Message{
SharedLocation: location,
})
```
```java
// Create shared location request
SharedLocationRequest locationRequest = new SharedLocation.SharedLocationRequest();
locationRequest.setCreatedByDeviceId(deviceId);
locationRequest.setLatitude(latitude);
locationRequest.setLongitude(longitude);
locationRequest.setEndAt(end_at);
// Convert request to SharedLocation
SharedLocation sharedLocation = new SharedLocation();
sharedLocation.setCreatedByDeviceId(locationRequest.getCreatedByDeviceId());
sharedLocation.setLatitude(locationRequest.getLatitude());
sharedLocation.setLongitude(locationRequest.getLongitude());
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
dateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
sharedLocation.setEndAt(dateFormat.parse(locationRequest.getEndAt()));
// Send message with shared location
MessageRequestObject messageRequest =
MessageRequestObject.builder()
.sharedLocation(sharedLocation)
.build();
Message message =
Message.send(testChannel.getType(), testChannel.getId())
.message(messageRequest)
.request()
.getMessage();
```
```ruby
@location_channel = @client.channel('messaging', channel_id: SecureRandom.uuid)
location = {
created_by_device_id: SecureRandom.uuid,
latitude: 40.7128,
longitude: -74.0060,
end_at: (Time.now + 3600).iso8601
}
response = @location_channel.send_message({
shared_location: location
})
```
```csharp
var channel = await CreateChannelAsync(createdByUserId: _user1.Id, members: new[] { _user1.Id });
// Create a shared location for live location sharing (with EndAt)
var location = new SharedLocationRequest
{
Longitude = longitude,
Latitude = latitude,
EndAt = DateTimeOffset.UtcNow.AddHours(1), // Set duration for live location
CreatedByDeviceId = "test-device",
};
// Send a message with shared location
var messageRequest = new MessageRequest
{
Text = "Test message for live location sharing",
SharedLocation = location,
};
var messageResp = await _messageClient.SendMessageAsync(
channel.Type,
channel.Id,
messageRequest,
_user1.Id);
```
```python
# Send a live location message (with end_at)
now = datetime.datetime.now(datetime.timezone.utc)
one_hour_later = now + datetime.timedelta(hours=1)
shared_location = {
"created_by_device_id": "test_device_id",
"latitude": 37.7749,
"longitude": -122.4194,
"end_at": one_hour_later.isoformat(),
}
channel.send_message(
{"text": "Message with live location", "shared_location": shared_location},
user_id,
)
```
```php
// Send a live location message (with end_at)
$oneHourLater = (new DateTimeImmutable('now', new DateTimeZone('UTC')))->modify('+1 hour')->format(DateTime::ATOM);
$sharedLocation = [
'created_by_device_id' => 'test_device_id',
'latitude' => 37.7749,
'longitude' => -122.4194,
'end_at' => $oneHourLater,
];
$channel->sendMessage(
['shared_location' => $sharedLocation],
$userId
);
```
```dart
final initialLocation = LocationCoordinates(
latitude: 37.7749,
longitude: -122.4194,
);
// Send a live location message with an end time.
final response = await channel.startLiveLocationSharing(
location: initialLocation,
endSharingAt: DateTime.timestamp().add(Duration(hours: 1)), // 1 hour later
createdByDeviceId: 'test_device_id', // Optional
);
```
## Stopping live location sharing
You can stop live location sharing for a specific message using the message controller:
```swift
/// Get the message controller for the live location message
let messageController = chatClient.messageController(
cid: channelId,
messageId: liveLocationMessageId
)
/// Stop live location sharing
messageController.stopLiveLocationSharing()
```
```javascript
const channel = client.channel("type", "id");
// to stop location sharing at least message id has to be provided
channel.stopLiveLocationSharing({
message_id: "message-id",
});
```
```kotlin
// Stop a live location sharing.
chatClient.stopLiveLocationSharing(
messageId = "live-location-message-id",
deviceId = "my-device-id",
).enqueue { /* ... */ }
```
```go
// Set end_at to now
end_at := time.Now()
location := &SharedLocation{
MessageID: message_id,
Longitude: &longitude,
Latitude: &latitude,
EndAt: &end_at,
CreatedByDeviceID: "test-device",
}
// Update the live location
c.UpdateUserActiveLocation(ctx, user.ID, newLocation)
```
```java
// Create SharedLocation request with time.now
SharedLocationRequest updatedLocationRequest = new SharedLocation.SharedLocationRequest();
updatedLocationRequest.setMessageId(initialMessage.getId());
updatedLocationRequest.setCreatedByDeviceId(deviceId);
updatedLocationRequest.setEndAt(LocalDate.now());
// Update the live location
SharedLocation.SharedLocationResponse updateResponse =
SharedLocation.updateLocation()
.userId(testUserRequestObject.getId())
.request(updatedLocationRequest)
.request();
```
```ruby
location = {
message_id: message_id,
created_by_device_id: "test-device",
end_at: Time.now.iso8601
}
@client.update_location(location)
```
```csharp
// Stop live location sharing by setting EndAt to now
var stopLocationRequest = new SharedLocationRequest
{
MessageId = liveLocationMessageId, // The ID of the live location message
Longitude = longitude,
Latitude = latitude,
EndAt = DateTimeOffset.UtcNow, // Set EndAt to now to stop sharing
CreatedByDeviceId = "test-device",
};
// Update the live location
var response = await UpdateLocationAsync(userID, stopLocationRequest);
```
```python
# Update the user's live location (e.g., when device location changes)
location_data = {
"created_by_device_id": "test_device_id",
"latitude": new_latitude,
"longitude": new_longitude,
}
client.update_user_location(
user_id,
message_id,
location_data
)
```
```php
// Update the user's live location (e.g., when device location changes)
$locationData = [
'created_by_device_id' => 'test_device_id',
'latitude' => $newLatitude,
'longitude' => $newLongitude,
];
$client->updateUserActiveLiveLocation(
$userId,
$messageId,
$locationData
);
```
```dart
// Stop live location sharing for a specific message.
final location = await client.stopLiveLocation(
messageId: liveLocationMessageId,
createdByDeviceId: 'test_device_id', // Optional
);
```
## Updating live location
Your application must implement location tracking and provide updates to the SDK. The SDK handles updating all the current user's active live location messages and provides a throttling mechanism to prevent excessive API calls.
```swift
/// Get the current user controller.
let currentUserController = chatClient.currentUserController()
/// Set delegate to receive live location updates.
currentUserController.delegate = self
/// Load active live locations (call only once at app start or when chat is initialized)
currentUserController.loadActiveLiveLocationMessages()
/// Update location when device location changes.
func locationDidUpdate(_ newLocation: LocationInfo) {
currentUserController.updateLiveLocation(newLocation)
}
```
```javascript
// simple call to update a location
await client.updateLocation({
latitude: 1,
longitude: 2,
message_id: "message-id",
});
```
```kotlin
// Query user's active live locations (call only once when user is connected).
chatClient.queryActiveLocations().enqueue { /* ... */ }
// Listen for changes in current user's active live locations.
chatClient.globalStateFlow
.flatMapLatest { it.currentUserActiveLiveLocations }
.onEach { userActiveLiveLocations ->
if (userActiveLiveLocations.isEmpty()) {
// Stop receiving device location updates if there's no active live locations.
} else {
// Start receiving device location updates (check for location permissions).
}
}
.launchIn(coroutineScope)
// Update live location when device location changes.
for (deviceLocation in result.locations) {
userActiveLiveLocations
.filterNot { it.endAt?.before(Date()) ?: false } // Filter out expired locations
.forEach { activeLiveLocation ->
chatClient.updateLiveLocation(
messageId = activeLiveLocation.messageId,
latitude = deviceLocation.latitude,
longitude = deviceLocation.longitude,
deviceId = "my-device-id",
).enqueue { /* ... */ }
}
}
```
```go
// Get current user active live locations
userActiveLiveLocations, err := c.GetUserActiveLocations(ctx, user.ID)
// New location to set
end_at := time.Now()
newLocation := &SharedLocation{
Longitude: &longitude,
Latitude: &latitude,
EndAt: &end_at,
CreatedByDeviceID: "test-device",
}
// Update active live location of the current user
for _, location := range userActiveLiveLocations.ActiveLiveLocations {
newLocation.MessageID = location.MessageID
c.UpdateUserActiveLocation(ctx, user.ID, newLocation)
}
```
```java
// Get active live locations
ActiveLiveLocationsResponse activeLocations =
SharedLocation.getLocations().userId(userRequestObject.getId()).request();
// Create updated location request
SharedLocationRequest updatedLocationRequest = new SharedLocation.SharedLocationRequest();
updatedLocationRequest.setMessageId(initialMessage.getId());
updatedLocationRequest.setCreatedByDeviceId(deviceId);
updatedLocationRequest.setEndAt(end_at);
// Update the live location
SharedLocation.SharedLocationResponse updateResponse =
SharedLocation.updateLocation()
.request(updatedLocationRequest)
.request();
```
```ruby
location = {
message_id: message_id,
created_by_device_id: "test-device",
end_at: Time.now.iso8601
}
@client.update_location(location)
```
```csharp
// Get all active live locations for the current user
var activeLocations = await GetSharedLocationsAsync(userID);
// New location to set (e.g., from device location update)
var newLocation = new SharedLocationRequest
{
Longitude = newLongitude, // updated longitude
Latitude = newLatitude, // updated latitude
EndAt = endAt, // keep the same end time
CreatedByDeviceId = "test-device",
};
// Update all active live locations for the user
foreach (var location in activeLocations.ActiveLiveLocations)
{
newLocation.MessageId = location.MessageId;
await UpdateLocationAsync(userID, newLocation);
}
```
```python
# Update the user's live location (e.g., when device location changes)
location_data = {
"created_by_device_id": "test_device_id",
"latitude": new_latitude,
"longitude": new_longitude,
}
client.update_user_location(
user_id,
message_id,
location_data
)
```
```php
// Update the user's live location (e.g., when device location changes)
$location = [
'latitude' => $newLatitude,
'longitude' => $newLongitude
];
$response = $client->updateUserActiveLiveLocation($userId, $messageId, $location);
```
```dart
// Update the user's live location (e.g., when device location changes)
final updatedLocation = await client.updateLiveLocation(
messageId: liveLocationMessageId,
createdByDeviceId: 'test_device_id', // Optional
location: LocationCoordinates(
latitude: newLatitude,
longitude: newLongitude,
),
);
```
Whenever the location is updated, the message will automatically be updated with the new location.
The SDK will also notify your application when it should start or stop location tracking as well as when the active live location messages change.
```swift
extension SomeObject: CurrentChatUserControllerDelegate {
/// Called when the user starts sharing a live location and it wasn't already sharing a live location
func currentUserControllerDidStartSharingLiveLocation(
_ controller: CurrentChatUserController
) {
// Start location monitoring (Needs to be implemented by the application)
startLocationTracking()
}
/// Called when all live location sharing stops
func currentUserControllerDidStopSharingLiveLocation(
_ controller: CurrentChatUserController
) {
// Stop location monitoring
stopLocationTracking()
}
/// Called when active live location messages change
func currentUserController(
_ controller: CurrentChatUserController,
didChangeActiveLiveLocationMessages messages: [ChatMessage]
) {
// You can use this delegate method to track the active live location messages and
// if needed render all of them in a UI component or you can use this for finer control
// when to start or stop tracking locations.
}
/// Called when a live location update fails
func currentUserController(
_ controller: CurrentChatUserController,
didFailToUpdateLiveLocation location: SharedLocation,
with error: Error
) {
// Handle error if needed
}
}
```
```dart
// You can listen to the current user's active live locations in order to determine when to start
// or stop location tracking.
_activeLiveLocationsSubscription = _client.state.activeLiveLocationsStream
.distinct((prev, curr) => prev.length == curr.length)
.listen((locations) async {
// If there are no more active locations to update, stop tracking.
if (locations.isEmpty) return _stopTrackingLocation();
// Otherwise, start tracking the user's location.
return _startTrackingLocation();
});
```
```javascript
// reporter function necessary for LiveLocationManager
const watchLocation = (handler) => {
const timer = setInterval(() => {
// retrieval of current location is a app-specific logic
getCurrentPosition((position) => {
handler({
latitude: position.coords.latitude,
longitude: position.coords.longitude,
});
});
}, 5000);
return () => {
clearInterval(timer);
};
};
// the manager takes care of registering/ unregistering and reporting location updates
const manager = new LiveLocationManager({
client,
getDeviceId, // function should generate a unique device id
watchLocation, // function should retrieve the location and pass it to the handler function
});
// to start watching and reporting the manager subscriptions have to be initiated
manager.init();
// to stop watching and reporting the manager subscriptions have cleaned up
manager.unregisterSubscriptions();
```
## Events
Whenever a location is created or updated, the following WebSocket events will be sent:
- `message.new`: When a new location message is created.
- `message.updated`: When a location message is updated.
In Dart, these events are resolved to more specific location events:
- `location.shared`: When a new location message is created.
- `location.updated`: When a location message is updated.
You can easily check if a message is a location message by checking the `message.sharedLocation` property. For example, you can use this events to render the locations in a map view.
```swift
let eventsController = ChatClient.shared.eventsController()
eventsController.delegate = self
extension CustomMapView: EventsControllerDelegate {
func eventsController(_ controller: EventsController, didReceiveEvent event: any Event) {
/// Make sure the event is for the current channel.
guard event.cid == currentChannelId else {
return
}
if let event = event as? MessageNewEvent, let sharedLocation = event.message.sharedLocation {
// Add the new location to the map.
} else if let event = event as? MessageUpdatedEvent, let sharedLocation = event.message.sharedLocation { {
// Update the location on the map.
}
}
}
```
```kotlin
chatClient.subscribeFor(NewMessageEvent::class, MessageUpdatedEvent::class) { event ->
// Check if the event is for the watching channel.
if ((event as? CidEvent)?.cid == "my-watching-cid") {
when (event) {
is NewMessageEvent -> event.message.sharedLocation?.let { location ->
// Add a new location to the map.
}
is MessageUpdatedEvent -> event.message.sharedLocation?.let { location ->
// Update the existing location in the map.
}
else -> Unit
}
}
}
```
```dart
// Listen for location-specific events
client.on(EventType.locationShared).listen((event) {
// Handle location shared event if needed
});
client.on(EventType.locationUpdated).listen((event) {
// Handle location updated event if needed
});
```
