Build scalable backend systems with Node.js
Node.js Development focuses on building server-side applications using JavaScript, enabling full-stack development with a single language. As a Node.js developer, you will build REST APIs, handle authentication, work with databases, implement real-time features, and deploy scalable backend systems. This comprehensive roadmap covers JavaScript fundamentals, Node.js core modules, Express.js, database integration (MongoDB, PostgreSQL), authentication & authorization, testing, microservices, and deployment. Node.js is used by companies like Netflix, LinkedIn, Uber, and PayPal for its performance and scalability. The role requires strong JavaScript skills, understanding of asynchronous programming, database knowledge, and ability to build secure, performant APIs. Node.js developers often work on full-stack applications, microservices, and real-time systems.
