After calling `terminate()` only the `clearIndexedDbPersistence()` function may be used. Any other function will throw a `FirestoreError`. To restart after termination, create a new instance of FirebaseFirestore with [getFirestore()](./firestore_.getfirestore.md). Termination does not cancel any pending writes, and any promises that are awaiting a response from the server will not be resolved. If you have persistence enabled, the next time you start this instance, it will resume sending these writes to the server. 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()` 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_.firebasefirestore.md) | | Returns: Promise<void> A promise that is resolved when the instance has been successfully terminated.
