Learn to run and structure a real Node.js project from scratch — install Node and npm, run scripts and the REPL, understand the V8 runtime and event loop, and organise code with CommonJS and ES modules. You will finish able to stand up a package.json-driven project with dependencies and npm scripts, confident about how Node executes your code.
Master Node.js core modules to read, write and process files and system resources with confidence. You will use fs, path, os, process and url, handle text and JSON safely, react to events with EventEmitter, and stream large files without exhausting memory.
Build a working REST API in Node.js from the ground up: start with the core http module, then move to Express to route requests, parse JSON bodies and return correct status codes. You will finish able to design and ship a full CRUD API over an in-memory store.
Write reliable asynchronous code in Node.js — model non-blocking I/O correctly, replace nested callbacks with Promises, and read and write clear async/await. You will finish able to chain, parallelise and error-handle asynchronous work without race conditions or swallowed failures.
