`createFilePersister`

The createFilePersister function creates a Persister object that can persist the Store to a local file (in an appropriate environment).

createFilePersister(
  store: Store,
  filePath: string,
  onIgnoredError?: (error: any) => void,
): FilePersister

	Type	Description
`store`	`Store`	The `Store` to persist.
`filePath`	`string`	The location of the local file to persist the `Store` to.
`onIgnoredError?`	`(error: any) => void`	An optional handler for the errors that the `Persister` would otherwise ignore when trying to save or load data. This is suitable for debugging persistence issues in a development environment, since v4.0.4.
returns	`FilePersister`	A reference to the new `FilePersister` object.

As well as providing a reference to the Store to persist, you must provide a filePath parameter which identifies the file to persist it to.

Example

This example creates a FilePersister object and persists the Store to a local file.

const store = createStore().setTables({pets: {fido: {species: 'dog'}}});
const persister = createFilePersister(store, '/app/persisted.json');

await persister.save();
// Store JSON will be saved to the file.

await persister.load();
// Store JSON will be loaded from the file.

persister.destroy();
