name is required when creating a user. The function will throw if you don’t provide a name and the user does not exist yet.

Properties that are nil will not be changed. To clear / reset a property to the default, call UserRef.deleteFields instead.

struct UserSubscription

Method Overview

unsubscribe

Unsubscribe from this resource and stop receiving updates.

Properties

connected
: Deferred<UserSubscriptionState>

Resolves when the subscription starts receiving updates from the server.

state
: UserSubscriptionState { get }

The current state of the subscription

An enum with the following fields:

type is one of “pending”, “active”, “unsubscribed”, or “error”.

When type is “pending”, this property is UserSubscriptionState.pending.

When type is “active”, this property is UserSubscriptionState.active(latestSnapshot:).

When type is “unsubscribed”, this property is UserSubscriptionState.unsubscribed.

When type is “error”, this property is UserSubscriptionState.error(_:).

terminated
: Deferred<UserSubscriptionState>

Resolves when the subscription permanently stops receiving updates from the server.

This is either because you unsubscribed or because the subscription encountered an unrecoverable error.

unsubscribe

func userSubscription.unsubscribe()

Unsubscribe from this resource and stop receiving updates.

If the subscription is already in the UserSubscriptionState.unsubscribed or UserSubscriptionState.error(_:) state, this is a no-op.

Returns

Void

enum UserSubscriptionState

Values:

  • pending
  • unsubscribed
  • active(latestSnapshot:)

    The most recently received snapshot for the user, or nil if the user does not exist yet.

    latestSnapshot (optional)
    : UserSnapshot?

    : TalkJSError

struct UserOnlineSnapshot

A snapshot of a user’s online status at a given moment in time.

Properties

isConnected
: Bool

Whether the user is connected right now

Users are considered connected whenever they have an active websocket connection to the TalkJS servers. In practice, this means:

People using the JS Data API are considered connected if they are subscribed to something, or if they sent a request in the last few seconds. Creating a TalkSession is not enough to appear connected.

People using Components, are considered connected if they have a UI open.

People using the JavaScript SDK, React SDK, React Native SDK, or Flutter SDK are considered connected whenever they have an active Session object.

The user this snapshot relates to
