FileVault (My File Sharing App)

Hey! This is a file sharing application I built. It's basically like a personal Google Drive where you can store your files and share them with others securely. I built this to understand how full-stack development works, especially file handling and security.

What it does

It's not just a simple upload/download app. I've added a bunch of features:

• Upload stuff: You can upload multiple files at once. I'm using AWS S3 so it can handle big files.
• Secure Login: You have to register and login to see your files. It uses JWT for security.
• Sharing: You can share files with other people using their email.
• AI Summary: This is the newest feature! You can click on a file and it will use AI to give you a short summary of what's inside. Useful if you have long documents.
• Mobile Friendly: Works good on phones too.

Technology I Used

• Frontend: React with Vite (managed to make it look decent with Tailwind CSS).
• Backend: Node.js and Express.
• Database: MongoDB for storing user data and file info.
• Storage: AWS S3 for the actual files.

How to run it locally

If you want to try this out on your machine, here is what you need to do.

Prerequisites

You need Node.js installed and a MongoDB database (local or Atlas works). Also you need an AWS S3 bucket for file uploads.

Steps

1. Clone the repo

   git clone https://github.com/trainblazer072/file-sharing-app.git
   cd file-sharing-app

2. Setup Backend Go to the server folder and install packages:

   cd server
   npm install

   You need to make a .env file in the server folder with your keys:

   PORT=3000
   MONGO_URI=mongodb://localhost:27017/file-sharing-app
   JWT_SECRET=some_secret_key
   AWS_ACCESS_KEY_ID=your_aws_key
   AWS_SECRET_ACCESS_KEY=your_aws_secret
   AWS_REGION=us-east-1
   AWS_BUCKET_NAME=your_bucket_name

   Then start it:

   npm run dev

3. Setup Frontend Open a new terminal, go to client folder:

   cd client
   npm install

   Make a .env file here too:

   VITE_API_URL=http://localhost:3000

   Run it:

   npm run dev

   It should open on http://localhost:5173.

Deployment

I deployed the backend and frontend on Vercel. If you want to deploy, just push the server and client folders to those services and set the environment variables there.
