Interface TaskSnapshotObserver

Deprecated

Use the exported types directly instead. FirebaseStorageTypes namespace is kept for backwards compatibility.

const ref = firebase.storage().ref(...);
const task = ref.put(...)

task.on('state_changed', {
  next(taskSnapshot) {
    console.log(taskSnapshot.state);
  },
  error(error) {
    console.error(error.message);
  },
  complete() {
    console.log('Task complete');
  },
})
