Read-only properties #
| Property name | Type | Description |
|---|---|---|
authenticated | boolean | Returns true if the SDK holds a valid token |
connected | boolean | Returns true if the SDK is currently connected to a Kuzzle server. |
offlineQueue | object[] | Contains the queued requests during offline mode |
protocol | Protocol | Protocol used by the SDK |
connected #
The connected property wraps the underlying protocol connected property. See the associated documentation:
Writable properties #
| Property name | Type | Description |
|---|---|---|
autoQueue | boolean | If true, automatically queues all requests during offline mode |
autoReplay | boolean | If true, automatically replays queued requests on a reconnected event |
autoResubscribe | boolean | If true, automatically renews all subscriptions on a reconnected event |
jwt | string | Authentication token |
offlineQueueLoader | function | Called before dequeuing requests after exiting offline mode, to add items at the beginning of the offline queue |
queueFilter | function | Custom function called during offline mode to filter queued requests on-the-fly |
queueMaxSize | number | Number of maximum requests kept during offline mode |
queueTTL | number | Time a queued request is kept during offline mode, in milliseconds |
replayInterval | number | Delay between each replayed requests |
volatile | object | Common volatile data, will be sent to all future requests |
offlineQueueLoader #
The offlineQueueLoader property must be set with a function of one of the following formats:
Object[] offlineQueueLoader()
Promise<Object[]> offlineQueueLoader()The returned (or resolved) array must contain objects, each with the following properties:
| Property | Type | Description |
|---|---|---|
query | object | Object representing the request that is about to be sent to Kuzzle, following the Kuzzle API format |
reject | function | A Promise.reject function |
resolve | function | A Promise.resolve function |
queueFilter #
The queueFilter property must be set with a function of the following form:
boolean queueFilter(request)The request argument is an object representing the request that is about to be sent to Kuzzle, following the Kuzzle API format.
queueMaxSize #
This property defines the size of the offline buffer, which is a first-in first-out (FIFO) queue.
This means that if the queueMaxSize limit is reached, older requests are discarded to make room for newer requests.
If queueMaxSize is set to a number lower than, or equal to 0, then an unlimited number of requests is kept in the offline buffer. Note that doing so may lead to a crash due to memory saturation, if there are too many requests held in memory.
queueTTL #
If the queueTTL property is set to a number lower than, or equal to 0, then requests never expire and are kept indefinitely.
volatile #
Multiple methods allow passing specific volatile data.
These volatile data will be merged with the global Kuzzle volatile object when sending the request, with the request specific volatile taking priority over the global ones.
