https://github.com/Kaitosss/ExamDepot.git

Step2: Install dependencies

Run the following command to install both frontend and backend dependencies:

bun install --cwd ExamDepot/frontend && npm install --prefix ExamDepot/backend

Step3: Configure environment variables

Create a .env file inside the backend folder with the following content:

PORT=8000
JWT_SECRET=your_jwt_secret_key_here
MONGODB_URL=your_mongodb_connection_string_here
CLOUDINARY_CLOUD_NAME=your_cloudinary_cloud_name
CLOUDINARY_API_KEY=your_cloudinary_api_key
CLOUDINARY_API_SECRET=your_cloudinary_api_secret

Step4: Create and run seed.js to populate the database

Before running the app, you need to add initial data to your MongoDB database.

1. Create a file named seed.js in the backend folder with the following example content:

    import  "dotenv/config"
    import mongoose from  "mongoose";
    import Users from  "./models/users.model.js";
    import bcryptjs from  "bcryptjs";
    await mongoose.connect(process.env.MONGODB_URL);
    const  username  =  "your_username";
    const  password  =  "your_password";
    const  role  =  "admin";
    const  profilePic  =  "https://upload.wikimedia.org/wikipedia/commons/8/89/Portrait_Placeholder.png"
    const  salt  =  await bcryptjs.genSalt(10);
    const  hashpassword  =  await bcryptjs.hash(password, salt);
    const  user  =  new Users({
    username,
    password: hashpassword,
    role,
    profilePic
    });
    await user.save();
    console.log("Admin inserted successfully");
    process.exit(0);
   

2. Run the seed script:

    node ExamDepot/backend/seed.js
   

Step5: Run the project

Start frontend (React + Bun):

bun run --cwd ExamDepot/frontend dev

Start backend (Express + npm):

npm start --prefix ExamDepot/backend
