[Home](./index.md) > [@firebase/firestore](./firestore.md) > [lite](./firestore_lite.md) > [terminate](./firestore_lite.terminate.md) ## terminate() function Terminates the provided Firestore instance. After calling `terminate()` only the `clearIndexedDbPersistence()` functions may be used. Any other function will throw a `FirestoreError`. Termination does not cancel any pending writes, and any promises that are awaiting a response from the server will not be resolved. To restart after termination, create a new instance of FirebaseFirestore with [getFirestore()](./firestore_.getfirestore.md). Note: Under normal circumstances, calling `terminate()` is not required. This function is useful only when you want to force this instance to release all of its resources or in combination with [clearIndexedDbPersistence()](./firestore_.clearindexeddbpersistence.md) to ensure that all local state is destroyed between test runs. Signature: ```typescript export declare function terminate(firestore: FirebaseFirestore): Promise; ``` ## Parameters | Parameter | Type | Description | | --- | --- | --- | | firestore | [FirebaseFirestore](./firestore_lite.firebasefirestore.md) | The Firestore instance to terminate. | Returns: Promise<void> A promise that is resolved when the instance has been successfully terminated.
