[Fixed] Read one field from firestore

Issue

I wanna show the name field of my document in users collection in my firebase firestore using angular

let name = this.afs.collection('users').doc('doc_id').get('name');
console.log(name);

Solution

fname  = null;
        
this.users = this.afs.collection('users', ref => ref.where("uid", "==", id)).valueChanges();
        
    this.users.subscribe(users => {
       for(let user of users){
          this.fname = user.firstName;
       }
    })
        
console.log(fname);
