Frequently Asked Questions
What is Express.js 4.x and how is it used in backend development?
Express.js 4.x is a minimal and flexible Node.js web application framework providing robust features for web and mobile applications. Express.js provides: fast routing system for handling HTTP requests, middleware for request processing and response handling, template engine integration (EJS, Pug, Handlebars), robust API building capabilities, HTTP utility methods and middleware, and extensive ecosystem of plugins and middleware. Express is used for: RESTful API development, web application backends, microservices architecture, real-time applications with WebSockets, authentication and authorization systems, and full-stack JavaScript applications. It's the most popular Node.js framework, known for minimal overhead, flexibility, and extensive community support.
How does the AI help with Express.js API development?
The AI generates Express.js API code including: route definitions with proper HTTP methods (GET, POST, PUT, DELETE), middleware functions for authentication and validation, request body parsing and validation, response formatting and error handling, database integration with ORMs (Mongoose, Sequelize, Prisma), async/await patterns and promise handling, and API documentation. It follows Express.js best practices and Node.js conventions for production-ready applications.
Can it help with authentication and security in Express.js?
Yes! The AI generates authentication and security code including: JWT token generation and verification, session management with express-session, password hashing with bcrypt, authentication middleware and route protection, OAuth integration with Passport.js, CORS configuration for cross-origin requests, input validation and sanitization, and security headers with helmet.js. It creates secure, production-ready authentication systems following security best practices.
Does it support database integration and ORM usage?
Absolutely! The AI understands database integration with Express.js including: MongoDB with Mongoose ORM, PostgreSQL/MySQL with Sequelize ORM, Prisma for modern database access, connection pooling and error handling, database migrations and seeding, query optimization and indexing, and transaction management. It generates complete database integration code with proper connection handling, error management, and query optimization for scalable applications.
