I'm practicing some Angular/Ionic and am having a bit of a hard time figuring out how i get an offerLists filter by city,



this, is how i get all offres AllOffer.ts,
I get the offers across all users, I have to load all user data. like this:



export class AllOffresPage {

public offreList: Array<any>;

constructor(public navCtrl: NavController, public navParams: NavParams,
private db : AngularFireDatabase) {
}

ionViewDidLoad() {
let ref = firebase.database().ref("userProfile");
ref.on("value", userListSnapshot => {
this.offreList = ;
userListSnapshot.forEach(userSnapshot => {
let offerListSnapshot = userSnapshot.child("offreList");

offerListSnapshot.forEach(offerSnapshot => {
this.offreList.push({
id: offerSnapshot.key,
titre: offerSnapshot.val().titre,
sector: offerSnapshot.val().sector,
city: offerSnapshot.val().city,
descrip: offerSnapshot.val().descrip,
});
console.log(offerListSnapshot.key)
return false;
});
})
});
}


Now the question is how i get an offerLists filter by city,



 export class OffreByVillePage {

constructor(public navCtrl: NavController, public navParams: NavParams) {
}

ionViewDidLoad() {

// I don't know the code to show data filtered by city, I m stacking for
2 days
}

    Firebase has pretty good documentation on sorting and filtering data, and there have been a lot of questions on querying the database. I recommend you spend some time on those, give it a try yourself, and post back with the concrete query code if you get stuck.
