Firebase Storage getDownloadUrl() "is not a function"

Question

let storage = firebase.storage();
let storageRef = storage.ref("EnglishVideos/" + movieTitle + "/" + movieTitle + "_full.mp4");
    console.log(storageRef); // looks OK, no error messages

The above code works, the object returned from Firebase Storage has the correct location, no error messages.

But getDownloadUrl() doesn't work:

let myURL = storageRef.getDownloadUrl();
console.log(myURL); // TypeError: storageRef.getDownloadUrl is not a function

The error is TypeError: storageRef.getDownloadUrl is not a function. It seems like a prototype chain bug. I'm using AngularJS, maybe I didn't inject a necessary dependency into my controller? I injected $firebaseStorage into the controller but it didn't help. My calls to Firebase Realtime Database from this controller are working fine.

Answer 1

It's getDownloadURL, not getDownloadUrl. Capitalization. My working code is

var storageRef = firebase.storage().ref("EnglishVideos/" + movieTitle + "/" + movieTitle + "_full.mp4");
  storageRef.getDownloadURL().then(function(url) {
    console.log(url);
  });

The "official" version is

var storageRef = firebase.storage.ref("folderName/file.jpg");
storageRef.getDownloadURL().then(function(url) {
  console.log(url);
});

Note that I needed a () after storage, i.e., storage().
