Before updating to V9, I use this:
let data = doc.data();
for (let field in data) {
let value = data[field];
// If value is an instance of Timestamp, convert it to javascript Date()
if (value instanceof firebase.firestore.Timestamp) {
data[field] = value.toDate();
}
}
But now, after updating to V9, I run into 2 problems, and the documentation mentions nothing about Timestamp for javascript SDK:
firebase.firestore.Timestamp is no longer available to use to check if a field is a Timestamp Object.So my questions are, with the javascript V9 SDK:
How do I check if a field is an instance of Timestamp?
You can import Timestamp class from Firestore package.
How do I convert an instance of Timestamp into Date() object?
This method exists on a Timestamp object.
import { Timestamp } from "firebase/firestore"
const timeObj = new Timestamp();
console.log(timeObj instanceof Timestamp)
console.log(timeObj.toDate());
