Firebase Storage Rule to Disallow Overwrite

Question

I don't want user to be able upload a new file which is already exist with the same name in storage,

Here is what I've tried but still getting 403 when I upload a nonexist file.

service firebase.storage {
  match /b/projectid/o {
    match /{allPaths=**} {
      allow read;
      allow write: if !resource || request.resource.name == resource.name;
    }
  }
}

That doesn't solve my problem. I want to make my storage public but not allow anyone to overwrite any file.. In your situation you may have an auth rule. – Okan Kocyigit Apr 13 '17 at 15:21
