sync()#

sync: (params) => 
  | void
  | CleanupFn
  | SyncConfigRes;

Defined in: packages/db/src/types.ts:423

Parameters#

params#

begin#

() => void

Begin a new sync transaction.

collection#

Collection<T, TKey, any, any, any>

commit#

(signal?) => SyncAppliedReceipt

Commit the active sync transaction in FIFO order. Core accepts it at once, and an accepted transaction always applies. Returns true when its writes are visible, or a receipt that resolves when they become visible. While an optimistic transaction is persisting, it becomes visible when that transaction settles, together with the drop of its optimistic state. A signal that is already aborted abandons the transaction before acceptance, and the receipt rejects with an error named AbortError. Aborting after acceptance has no effect.

markError#

(error?) => void

Signal that initial sync failed before producing a usable snapshot. When supplied, error is preserved as the rejection reason from preload().

markReady#

() => void

Signal that a usable initial or recovered snapshot is available.

metadata?#

SyncMetadataApi<TKey>

truncate#

() => void

write#

(message) => void

Returns#

| void | CleanupFn | SyncConfigRes
