Coding Tutorials

Get started with Node.js and Express: routing, middleware, error handling, and building RESTful APIs from scratch.

Design and build RESTful APIs with Node.js: resource naming, HTTP methods, status codes, pagination, and versioning.

Implement authentication in Node.js: JWT tokens, session management, password hashing, and OAuth with Passport.js.

Connect Node.js to MongoDB with Mongoose: schemas, models, CRUD operations, population, indexing, and aggregation.

Understand Express middleware: built-in, custom, error-handling middleware, and how to build middleware pipelines.

Handle file uploads in Node.js: Multer for multipart forms, streaming large files, and cloud storage with S3.

Build real-time features with Socket.io: chat rooms, live notifications, presence detection, and scaling strategies.

Manage configuration with environment variables in Node.js: dotenv, validation, types, and twelve-factor app principles.

Write tests for Node.js APIs with Jest and Supertest: unit tests, integration tests, mocking, and TDD workflow.
