Learn Typescript

Overview

This course introduces you to the essential building blocks of TypeScript through a hands-on approach. You'll explore the fundamentals of TypeScript, learn to leverage TypeScript in React, and explore TypeScript in Express, plus build a TypeScript-based project. TypeScript catches errors before your code even runs. That means fewer bugs, smoother projects, and less rage-quitting! Plus, its type system makes refactoring and collaborating a breeze. In the first module, Getting Started with TypeScript, you'll cover: - Basic, literal & custom types - Arrays, objects & optional properties - Union types Module Two, Applying Advanced TypeScript concepts, introduces you to: - Narrowing, return types, and utility types - Function calls Module Three, TypeScript in React, will acquaint you with: - Initialising a React + TypeScript project - Typing useState, props & components - Working with JSX that may return null Finally, in the TypeScript in Express module, you'll get to grips with: - Setting up a TS-powered Express server - Typed requests, responses & data - Handling CORS, 404s, IDs & query params - Automating server restarts with confidence Ready to make your code safer? Let's go!

Syllabus

Getting Started with TypeScript

Learn the foundational concepts of TypeScript, including type annotations, custom types, and handling complex data structures, to build safer and more maintainable code.

Applying Advanced TypeScript Concepts

Master advanced TypeScript features like utility types, generics, type narrowing, and function return types to create robust, scalable, and reusable code solutions.

TypeScript in React

This module covers typing props, state, functions, and components—all with hands-on examples and challenges. You’ll gain confidence using TypeScript in real React projects and write safer, more predictable code.

TypeScript in Express

This module guides you through building a fully typed Express server with TypeScript, showing you how to structure routes, controllers, middleware, and data handling in a way that’s safe, scalable, and easy to maintain.
