Setting Up a Production-Ready TypeScript Express MongoDB Backend

I'll create a robust, maintainable backend setup with TypeScript, Express, and MongoDB that follows industry best practices.

Project Structure and Best Practices

This setup follows a modular architecture that's easy to maintain and scale:

src/
├── config/           # Configuration settings
├── controllers/      # Request handlers
├── middleware/       # Express middleware
├── models/           # Mongoose models with TypeScript interfaces
├── routes/           # API routes
├── schemas/          # Zod validation schemas
├── tests/            # Unit and integration tests
├── utils/            # Utility functions and classes
└── index.ts          # Application entry point

Key Features

Strong TypeScript Integration
- Strict type checking with proper interfaces and types
- Type-safe MongoDB models with Mongoose
- Proper error handling with typed errors
Robust Error Handling
- Custom AppError class for consistent error responses
- Global error handler middleware
- Validation error formatting
Request Validation
- Schema validation with Zod
- Type-safe request validation middleware
Security
- Helmet for HTTP headers security
- JWT authentication with proper typing
- Password hashing with bcrypt
- CORS configuration
Logging
- Structured logging with Winston
- Request ID tracking
- Performance monitoring
Testing
- Jest setup for unit and integration tests
- In-memory MongoDB for testing
- Supertest for API testing
Code Quality
- ESLint configuration
- Consistent code style
- Proper error handling

Deployment Recommendations

Docker
- Create a Dockerfile and docker-compose.yml for containerization
- Use multi-stage builds for smaller production images
CI/CD
- Set up GitHub Actions or similar for automated testing and deployment
- Include linting, type checking, and tests in the pipeline
Environment Variables
- Use a .env file for local development
- Use environment variables in production (Kubernetes secrets, etc.)
Monitoring
- Add Prometheus metrics for monitoring
- Set up health check endpoints
Documentation
- Add Swagger/OpenAPI documentation for your API
- Include README with setup instructions

This architecture provides a solid foundation that you can extend as your application grows, while maintaining type safety and code quality.

Please make sure to add the following environment variables to your project:

set up a nodejs express mongo and typescrip backend and it should be strictcly typed in typescript and use email and password for authentication also compile it should compile using typescript compiler and after compiling it should create a dist folder

Setting Up a Strictly Typed Node.js Express MongoDB Backend

I'll create a TypeScript backend with email/password authentication that compiles to a dist folder.

Project Structure

src/
├── config/           # Configuration settings
├── controllers/      # Request handlers
├── middleware/       # Express middleware
├── models/           # Mongoose models with TypeScript interfaces
├── routes/           # API routes
├── schemas/          # Zod validation schemas
├── types/            # TypeScript type definitions
├── utils/            # Utility functions and classes
└── index.ts          # Application entry point

Key Features

Strict TypeScript Configuration
- Full type safety with strict: true
- Proper interfaces for MongoDB models
- Type declarations for Express request extensions
Email/Password Authentication
- Secure password hashing with bcrypt
- JWT-based authentication
- Protected routes with middleware
TypeScript Compilation
- Configured to compile to a dist folder
- Source maps for debugging
- Declaration files generation
MongoDB Integration
- Strongly typed Mongoose models
- Type-safe database operations
- Proper error handling
Request Validation
- Schema validation with Zod
- Type-safe request validation

How to Use

Setup Environment Variables
- Copy .env.example to .env
- Fill in your MongoDB connection string and JWT secret
Install Dependencies
npm install
Development Mode
npm run dev
Build for Production
npm run build
This will compile TypeScript to JavaScript in the dist folder.
Start Production Server
npm start

API Endpoints

Authentication
- POST /api/auth/register - Register a new user
- POST /api/auth/login - Login with email and password
- GET /api/auth/me - Get current user (protected)
Users
- GET /api/users - Get all users (protected)
- GET /api/users/:id - Get user by ID (protected)
- PATCH /api/users/:id - Update user (protected)
- DELETE /api/users/:id - Delete user (protected)

Make sure to add the following environment variables to your project:
