This course is designed to help you go from beginner to confident backend developer by mastering the full Node.js backend ecosystem. You will not only learn how to write JavaScript and TypeScript for the backend, but also understand how real backend systems work behind the scenes. We start with strong programming fundamentals using JavaScript, then move into modern ES6+ features, asynchronous programming, and TypeScript for safer and more scalable backend code. After that, you will dive deep into Node.js itself, including the runtime, modules, events, streams, buffers, error handling, and performance basics.
You will also learn how backend communication really works through HTTP, REST APIs, request and response structure, status codes, API design, validation, pagination, filtering, and clean error handling. Then we move into real backend frameworks and tools used in production, including Express.js, Fastify, NestJS, and Sails.js. This course also gives you a strong database foundation. You will understand data modeling, transactions, indexing, performance thinking, and backend architecture concepts. Then you will work with PostgreSQL, MongoDB, and Prisma so you can build modern backend applications with both SQL and NoSQL approaches.
