FU-DL - File Uploader & Downloader

FU-DL is a lightweight and minimal web application I built during my internship at Datamonk. It is designed to provide a simple interface to manage files, and it excels at doing three core tasks:

• Upload Files

• List Uploaded Files

• Delete Files

The application uses AWS S3 as the storage backend to ensure scalability and durability of files, and uses SQLite to maintain metadata and references locally.

Key Features

• Upload files directly from the browser via a clean, responsive interface.

• List all uploaded files in an organized, paginated table.

• Delete files instantly both from the S3 bucket and the local database.

• Minimal frontend using pure HTML, CSS, and JavaScript—no frontend frameworks like React or Vue.

• Dockerized for ease of deployment in any environment.

How to set up

1. Clone the github repo.
2. Create the .env file with the necessary access keys and bucket information.
3. Create a test.db file which will be used to store the file ids used for uploading to S3 bucket.
4. Install all dependencies by running, npm install
5. Then run the index.js file in the project directory

NOTE: you can use the dockerfile to create the app in two commands, obviously the .env and test.db file should still be made.
