Image Storage Microservice

This microservice implements a basic CRUD for uploading, storing, and retrieving images using NestJS. Images are externally stored in Firebase Storage, and the endpoints support file upload, retrieval, and validation.

Project Description

This project provides a scalable and efficient image storage microservice, featuring:

• Image upload (with type and size validation).
• Storage in Firebase Storage.
• Image retrieval via public URLs.
• Security with JWT authentication to protect access to the endpoints (Mocked data, not real authentication process required).

Additional Features (Optional)

• Thumbnail generation (for image resizing).
• Audit logs to track who uploaded which file and when.
• Redis integration to cache URLs and improve performance.
