How To Handle Promise In Firestore

here is my code to check a doc is there in the collections this.shopCollection = this.afs.collection('shops', ref => { return ref.where('fulladdress', '==', myStri

Solution 1:

I got it working with some changes

Here is my code

this.afs.collection<Shop>('shops').ref.where('fulladdress', '==', myString)
      .get()
      .then(res => {
        if(res.docs.length == 0){
          //no documents found
        }else{
          //you got some documents
          res.forEach(shop => {
            console.log(shop.id);
            console.log(shop.data());
          })
        }
      }).catch(err => {
        console.log('something went wrong '+ err)
      });

i am not sure this is the right way, works fine for me.
