Defined in: packages/db/src/types.ts:445

Type Parameters#

T#

T extends object = Record<string, unknown>

TKey#

TKey extends string | number = string | number

Properties#

exportSyncMeta()?#

optional exportSyncMeta: () => unknown;

Defined in: packages/db/src/types.ts:500

Export adapter-specific metadata that lets hydration/persistence resume sync. The payload shape is owned by the adapter.

Returns#

unknown

getSyncMetadata()?#

optional getSyncMetadata: () => Record<string, unknown>;

Defined in: packages/db/src/types.ts:494

Get the sync metadata for insert operations

Returns#

Record<string, unknown>

Record containing relation information

importSyncMeta()?#

optional importSyncMeta: (meta) => void;

Defined in: packages/db/src/types.ts:505

Import adapter-specific metadata produced by exportSyncMeta.

Parameters#

meta#

unknown

Returns#

void

mergeSyncMeta()?#

optional mergeSyncMeta: (current, incoming) => unknown;

Defined in: packages/db/src/types.ts:510

Merge two adapter-specific metadata payloads during hydration.

Parameters#

current#

unknown

incoming#

unknown

Returns#

unknown

rowUpdateMode?#

optional rowUpdateMode: "full" | "partial";

Defined in: packages/db/src/types.ts:519

The row update mode used to sync to the collection.

Default#

partial

Description#

• partial: Updates contain only the changes to the row.
• full: Updates contain the entire row.

sync()#

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

Defined in: packages/db/src/types.ts:449

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.

invalidateLoadedSubsets#

() => void

Report that rows this adapter serves for loaded subsets may have shifted between served pages, after a refetch that the adapter started on its own has applied. Each ordered live query then re-establishes its window with a bounded repair from the start of its order. Calls in one turn are coalesced. Do not call it for results that answer a loadSubset call.

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#

(options?) => void

Replace the synced rows. By default the replacement also marks the Collection ready. Set markReady:false to publish without changing status, for example when confirming a committed write from a closed source. The last truncate in a transaction supplies its readiness intent.

write#

(message) => void

Returns#

| void | CleanupFn | SyncConfigRes
