The IConvergenceOptions interface represents that options that can be set within Convergence when connecting to a domain.

See the ConvergenceOptions implementation for the default settings.

Properties

Optionalconnection

connection: object

Options that configure the connection strategy.

Type declaration

  • Optional handshakeTimeout?: number

    The maximum time in seconds to wait for a successful handshake to be made after the web socket connection is successful.

  • Optional timeout?: number

    The maximum time in seconds to wait for a successful web socket connection to be made.

Optionaloffline

offline: object

Configures offline storage for Convergence. Several of these options are required to enable offline editing of data.

experimental

Type declaration

  • Optional modelSnapshotInterval?: number

    The number of operations after which a snapshot of local offline that is being edited should be taken. The default is 100.

    experimental
  • storage: IStorageAdapter

    The storage adapter to use for offline storage.

    experimental

Optionalprotocol

protocol: object

Configures the behavior of the messaging protocol subsystem.

Type declaration

  • defaultRequestTimeout: number

    The timeout for a request to the server, in seconds. Defaults to 10.

  • Optional heartbeat?: object

    Configures the keep-alive heartbeat.

    • enabled: boolean

      Determines if the heartbeat is enabled.

    • Optional pingInterval?: number

      Configures how long the client will wait, in seconds after the last message is received from the server before a ping will be sent. Defaults to 5.

    • Optional pongTimeout?: number

      Specifies the time in seconds the client will wait for a response from the server to a ping before considering the connection dead. Defaults to 10.

Optionalreconnect

reconnect: object

Options that configure how Convergence will reconnect when a connection is lost.

Type declaration

  • Optional autoReconnect?: boolean

    Whether to automatically reconnect. Default is true.

  • Optional fallbackAuth?: function

    The fallbackAuth method to use when a reconnect token is rejected. It provides the opportunity to use a fallback method of authentication.

    options.reconnect.fallbackAuth = (authChallenge:IFallbackAuthChallenge) => {
      return Authentication.fetchJWT().then(jwt => {
        authChallenge.jwt(jwt);
      })
    };
  • Optional reconnectIntervals?: number[]

    The intervals to use between reconnects. This array will be sorted from smallest to largest. When the largest interval is reached it will simply be repeated.

OptionalwebSocket

webSocket: object

Options that configure how Convergence will use WebSockets.

See the Node.js Usage section on [this page] for an example of these parameters in action.

Type declaration

  • Optional class?: IWebSocketClass

    The constructor to use when creating a web socket. Essentially this is class that should be used to represent the web socket.

  • Optional factory?: WebSocketFactory

    Defines the class / constructor that should be used to create WebSocket objects. This is useful when operating in NodeJS where a library like ws or isomorphic-ws can be used to provide a client side WebSocket API.
