PowerSyncBackendConnector

Properties

Property	Type	Description
fetchCredentials	() => Promise< null | PowerSyncCredentials >	Allows the PowerSync client to retrieve an authentication token from your backend which is used to authenticate against the PowerSync service. This should always fetch a fresh set of credentials - don't use cached values. Return null if the user is not signed in. Throw an error if credentials cannot be fetched due to a network error or other temporary error. This token is kept for the duration of a sync connection.
uploadData	(database: AbstractPowerSyncDatabase) => Promise< void >	Upload local changes to the app backend. Use AbstractPowerSyncDatabase.getCrudBatch to get a batch of changes to upload. Any thrown errors will result in a retry after the configured wait period (default: 5 seconds).
