How can I implement security rules for Firebase Storage in a Vue app?

To implement security rules for Firebase Storage in a Vue app, you need to define rules in the Firebase console. What specific access control do you need?

I want to allow users to upload files only if they are authenticated.

You can set up a rule like this:

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow write: if request.auth != null;
    }
  }
}

This rule allows authenticated users to upload files.

What if I want to restrict access to certain file types?

You can modify the rule to check the file type. For example:

allow write: if request.auth != null && request.resource.contentType.matches('image/.*');

This allows only authenticated users to upload images.

Can I also limit the size of the files being uploaded?

Yes, you can add a condition to check the file size. For instance:

allow write: if request.auth != null && request.resource.size < 5 * 1024 * 1024;

This limits uploads to files smaller than 5MB.
