How to import Cloud Firestore Timestamp object from the Firebase SDK?

I have a simple class that is operating on Timestamps:

import * as firebase from 'firebase/app'

export class Activity {
  public id:string
  public name:string
  public color:string
  public lastEventAt:firebase.firestore.Timestamp
  ⋮
}

I would like to access the type in the class without specifying the namespace like:

public lastEventAt:Timestamp

What should my import statement look like?

From Firebase 9 you can import timestamp like this:

import firebase from 'firebase/compat';
import Timestamp = firebase.firestore.Timestamp;

For previous versions use this solution:

import {firestore} from 'firebase/app';
import Timestamp = firestore.Timestamp;

If you want to abbreviate Timestamp from the firestore namespace, the easiest thing to do might just be this:

import * as firebase from 'firebase/app'

import Timestamp = firebase.firestore.Timestamp

export class Activity {
  public id:string
  public name:string
  public color:string
  public lastEventAt:Timestamp
  ⋮
}

It works equally well for me to create a type alias:

type Timestamp = firebase.firestore.Timestamp

TypeScript will figure out that it's the same as other types that point to the same Timestamp class.
