Cloud Firestore でサーバーの現在時刻を保存する

Posted at

概要

Firebase の Cloud Firestore でサーバーの現在時刻を保存する方法を調べたので、ご紹介します。

Firestore でサーバーの現在時刻を保存するサンプルコード

結論としては、 require("firebase-admin").firestore.FieldValue.serverTimestamp() を利用すれば良いです。

以下、Node.js のサンプルコードです。

const admin = require("firebase-admin");
const db = admin.firestore();
const FieldValue = admin.firestore.FieldValue;

let docRef = db.collection('objects').doc('some-id');

let updateTimestamp = docRef.update({
  timestamp: FieldValue.serverTimestamp()
});

以上、Cloud Firestore でサーバーの現在時刻を保存したい、現場からお送りしました。
