Approach

 import { DocumentData, FirestoreDataConverter, QueryDocumentSnapshot } from '@google-cloud/firestore' export const converter = < AppValue extends object >(validator?: (value: AppValue) => AppValue): FirestoreDataConverter<AppValue> => { return { fromFirestore: (snapshot: QueryDocumentSnapshot<AppValue>) => { let data = snapshot.data() Object.keys(data).forEach((key) => { // @ts-ignore if (typeof data[key].toDate == "function" && typeof data[key].seconds == "number") { // Timestamp型は扱いにくいのでDate型に強制変更 // @ts-ignore data[key] = data[key].toDate() } }) return data }, /* * Async Await syntax don't support!! * * Fix like below * toFirestore: (value: AppValue): DocumentData => { **/ async toFirestore: (value: AppValue): DocumentData => { if (validator) { return validator(value) } return value } } } export default converter
