How to cast a snapshot value into a dictionary value with typescript?

How can I convert a snapshot value into a dictionary value of type [String: AnyObject]

I am trying to accomplish the bellow line in swift but in Typescript, so that I can loop through the keys. How can I do that? How do I cast a snapshot returned by firebase query in typescript into a dictionary of [string: AnyObject]

let snapValue = snap.value as! [String: AnyObject]

TypeScript query:

const userRef = admin.database().ref('PeopleWhoFollowMe').child(uid)
const fetchAndUpdate = userRef.once('value')
.then(snap => {
