Load data from Firebase Firestore to array - angularjs












0















I'm trying get data from firestore. Connection is ok, data is downloading but with problems.



I'm based on https://firebase.google.com/docs/firestore/query-data/get-data example.



let list = ;

let products = function GetCollection() {
firestore.collection("products")
.get()
.then(function (querySnapshot) {
querySnapshot.forEach(function (doc) {
console.log(doc.id, " => ", doc.data());
list.push(doc.data());
});
$scope.collection = list;
});
}
products();

console.log("test");


After run this code, my list is empty but in console are listed all entries. During debuging i noticed that last line with console.log("test") is executed before all body of GetCollection() function.
This is problem with sync? Can anyone help me?

          yes this is expected behavior, console.log("test"); will be executed first. Because part .then(function (querySnapshot is a asynchronous call, what you are passing inside .then is a javascript promise, and that is asynchronous



          you should also use handle error as mentioned in below line
          .get(some comde). then ( function -- ). catch ( function (error) { console.log("Error getting cached document:", error); } )



          for testing purpose, you can use firebase synchronous version of method as well, generally firebase api have corresponding sync version of method, and if I remember correctly those are suffixed with "sync"
