📅 Development Timeline

Day 1: Backend Foundation ✅

Date: [Current Date]

Today marked the beginning of my TechShop Pro journey. I focused on establishing a solid backend foundation with authentication and basic project structure.

🏗️ What I Built

1. Project Infrastructure

# Project initialization
mkdir techshop-pro
cd techshop-pro
npm init -y

2. Dependencies Management Carefully selected and installed essential packages:

  • express - Web framework

  • mongoose - MongoDB integration

  • dotenv - Environment variable management

  • bcryptjs - Secure password hashing

  • jsonwebtoken - JWT implementation

  • cors - Cross-origin resource sharing

  • winston - Professional logging

  • prom-client - Application metrics

3. Database Architecture Implemented MongoDB connection with proper error handling and connection status logging.

4. User Authentication System

  • Created comprehensive User model with validation

  • Implemented secure password hashing

  • Built JWT-based authentication

  • Created protection middleware for secured routes

5. Security Measures

  • Environment variable configuration

  • Password complexity requirements

  • JWT token verification

  • CORS configuration for cross-origin requests

🧠 Key Learning Points

Database Design Patterns

  • Learned the importance of schema validation in MongoDB

  • Understanding of middleware functions in Mongoose

  • Implemented proper error handling for database operations

Authentication Security

  • JWT vs session-based authentication trade-offs

  • Importance of secure secret management

  • Password hashing best practices with bcrypt

API Design Principles

  • RESTful endpoint structure

  • Consistent error response formatting

  • Proper HTTP status code usage

🔧 Code Architecture Highlights

User Model with Built-in Security

// Password comparison method built into the model
userSchema.methods.comparePassword = async function(candidatePassword) {
  return await bcrypt.compare(candidatePassword, this.password);
};

Reusable Authentication Middleware

// Modular middleware for route protection
const protect = async (req, res, next) => {
  // Token extraction and verification logic
  // User attachment to request object
  // Error handling for unauthorized access
};

🧪 Testing & Verification

Successfully tested core functionality using cURL commands:

  • User registration endpoint

  • User login endpoint

  • Token generation and validation

📊 Day 1 Metrics

  • Lines of Code: ~200

  • Files Created: 6

  • Features Implemented: 4 core features

  • Time Invested: 6 hours

  • Tests Passed: 100% (manual testing)
