Questions & Answers

Q: How does the upload service handle file uploads to Firebase storage?

The upload service uses the Firebase API to create a promise for monitoring upload status. Upon completion, it saves key information like the download URL to Firebase database.

Q: Why is an attribute directive chosen over a component for the drag-and-drop functionality?

An attribute directive is preferred as it doesn't require an HTML template. It efficiently utilizes event emitters and host listeners to manage file drops and hover states.

Q: How does the directive communicate with the parent component?

The directive uses event emitters to send custom events like 'file drop' and 'file hover' to the parent component, enabling seamless interaction between the two.

Q: What additional features can be incorporated into the drag-and-drop file upload functionality?

Limiting file size, restricting file types, and implementing error handling are suggested enhancements for the feature.
