How To Get A Javascript Date Object From The New `firebase.firestore.fieldvalue.servertimestamp()`
Solution 1:
You just need to do this:
yourFirestoreTimestamp.toDate()
If you look at the Timestamp
object in the console you'll see that .toDate()
is a function available by default on each Timestamp
.

However, please note that when you haven't synced with Firestore yet
FieldValue.serverTimestamp()
gives nothing of value.
Only after you have synced with Firestore and the data is fetched again, the prop will be changed from serverTimestamp
→ to Timestamp
You'll also see much more information saved in a Timestamp
object:
Solution 2:
firebase.firestore.FieldValue.serverTimestamp()
just returns a sentinel object that you use when writing a field to a document. It indicates the server should replace it with an actual Timestamp
object. serverTimestamp()
itself does not contain any date information, and you can't convert it to a date.
When you write the sentinel value to a document, and read it back out, it will become a Timestamp
type object, which you can convert to a native Date object with its toDate()
method
Solution 3:
At last, I could get what I need
new Date(firebase.firestore.Timestamp.now().seconds*1000).toLocaleDateString()
