Web Development with TypeScript: From Basics to Deployment

This book is a comprehensive practical guide to modern web development with TypeScript. You will start from the very basics: installing the compiler, configuring tsconfig, working with basic types and interfaces. Gradually, you will move on to advanced topics — generics, conditional types, type mapping, and working with utility types.

Special attention is given to the practical application of TypeScript in real projects. You will learn how to:

• Set up a development environment and project build (Webpack, Vite, ESLint)
• Create type-safe React applications with hooks and context
• Develop a backend on Node.js with Express and TypeScript
• Work with databases via Prisma and TypeORM
• Write unit tests and integration tests with Jest
• Automate deployment via CI/CD (GitHub Actions, Docker)

The book consists of three parts. The first part covers the fundamentals of TypeScript — types, functions, classes, and modules. The second part covers the development of a full-fledged web application using the React + Node.js + PostgreSQL stack. The third part is hands-on experience: performance optimization, working with WebSocket, creating REST API and GraphQL servers, as well as deploying to Vercel, Netlify, and cloud servers.

Who this book is for:

• Beginner developers familiar with JavaScript who want to learn TypeScript
• Frontend developers transitioning from JavaScript to TypeScript
• Backend developers wanting to use TypeScript on the server
• Team leads and architects implementing TypeScript in their projects

Each chapter includes practical assignments with ready-made solutions. You don't just read theory — you build a real application from idea to production. At the end of the book, you will get a template for quickly starting new TypeScript projects.

The book is written in a lively style, with examples from real development and tips on best practices. All code examples are available in a GitHub repository. After reading, you will be able to confidently write type-safe code, avoid common mistakes, and build scalable web applications.
