What You Will Learn

How a simple monorepo works with Yarn workspaces

What design tokens are, and how to generate them with Styled-Dictionary

How to create a shared component library

Automate testing for accessibility issues (Axe) and visual changes (Chromatic)

Develop and document our design system with Storybook

How to publish with Github Actions and Changesets

How to provide a Tailwind configuration for other teams

In this course, we will dive into the world of design systems. We will learn how they can help developers increase their productivity, create consistency across a company's products, and ultimately speed up the development process.

We will start by covering the fundamental concepts of design systems, then move on to the architecture of a monorepo codebase. We will set up shared configurations for TypeScript, ESLint, and Prettier, and create a foundation package for hosting and distributing design tokens and assets.

Next, we will create a React package with demo components that are styled using our design system's style tokens. We will also create a Storybook package and learn the best practices for developing and documenting components with TypeScript. We will focus on styling our components in two ways: using CSS-in-JS with styled-components and JavaScript design tokens, as well as Tailwind CSS classes.

Finally, we will learn how to create tests for our React components using React Testing Library and AXE, and manage releases using changesets and set up a CI pipeline with GitHub Actions.

This course aims to be a comprehensive guide, or a cookbook, to building a complete company design system from scratch. By the end of the course, you will have the knowledge and skills to create a practical and maintainable design system for any organization.

👋 Hi! My name is Costa and I'm a Senior software engineer. Currently, I lead the design system at Neo4j, a system that is used by 8+ teams and more than 40 engineers.

I have been working with user interfaces and design for the last 5 years and have focused on shared front-end experience and tooling since 2020. I truly enjoy creating the best shared developer experiences possible, which inspired this course. In the course, you’ll not only get detailed instructions on how to create a complete company design system, you’ll also come to understand best practices that I acquired by building these systems from scratch previously at VisualEyes and Neo4j

Frequently Asked Questions

Who is this course for?

This course is for Web Developers that want an Engineering Design System Cookbook that will provide recipes they can use from day 1 to start building and shipping their own design system library.

What if I need help?

You can ask us questions anytime through the community Discord channel or by sending us a message.

What are the prerequisites?

This course assumes that you are familiar with React (or any front-end framework) and the basics of front-end development including HTML, CSS, and JavaScript. While TypeScript will be used, an absence of knowledge will not be a roadblock.
