Kuzzle #
Inherits from: KuzzleEventEmitter.
The Kuzzle class is the main class of the SDK. Once instantiated, it represents a connection to your Kuzzle server.
It gives access to the different features of the SDKs:
- access to the available controllers
- SDK events handling
- resilience to connection loss
- network request queue management
Network protocol #
Each instance of the class communicates with the Kuzzle server through a class representing a network protocol implementation.
The following protocols are available in the SDK JS 6:
Volatile data #
You can tell the Kuzzle SDK to attach a set of "volatile" data to each request. You can set it as an object contained in the volatile field of the Kuzzle constructor. The response to a request containing volatile data will contain the same data in its volatile field. This can be useful, for example, in real-time notifications for user join/leave notifications to provide additional informations about the client who sent the request.
Note that you can also set volatile data on a per-request basis (on requests that accept a volatile field in their options argument). In this case, per-request volatile data will be merged with the global volatile object set in the constructor. Per-request fields will override global ones.
