Build Your Own Spreadsheet

Test-driven development (TDD) is a skill developed through repeated practice.

In Build Your Own Spreadsheet, you will join me in a text-based pairing session and together we are creating a fully functional spreadsheet component. From the first design ideas, we are test-driving the code all the way to a polished, working product.

Along the way, you will:

• Bring spreadsheet features like cell editing and even formulas to life.
• Make thoughtful design trade-offs and improve your code through refactorings.
• Strengthen your TypeScript, React and testing skills with every chapter.

It's a non-trivial project that shows step-by-step how to apply TDD to something meaningful and complex. By the end, you will have the confidence and practical know-how to use test-driven development effectively in your own work.

Build Your Own Spreadsheet is for developers who want to improve their test-driven development skills through a real project. Whether you've dabbled in TDD and want to apply it more effectively, or you're an experienced engineer looking to refine your approach, this book gives you a real-world context to practice in. It's especially valuable for engineers working with TypeScript and React, but the principles and techniques you'll learn apply to any language, framework or project.
