Creating a new unique path to Firebase Storage, coupled with storing it in the database?

Question

I have a marketplace web app, where users can upload items, and of course they can also see images associated with these items. The problem is organizing the storage buckets

Answer 1

Apologies for poorly written (and untested) JS, but would something like this work?

// create a new push ID and update the DB with some information
var currentItemRef = itemsRef.push({
    title: title,
    description: description,
    tags: tags,
    price: price,
}).then(function() {
  var storageRef = firebase.storage().ref();
  // currentItemRef.name is the unique key from the DB
  return storageRef.child(currentItemRef.name + '/' + imageNames[x]).putString(images[x], 'base64');
}).then(function(snapshot) {
  // update the DB with the download URL
  return currentItemRef.update({
    url: snapshot.metadata.downloadURLs[0]
  });
}).catch(function(error) {
  console.error(error);
});
