Modeling UI with State Machines should be the norm.

A practical guide to building better interfaces with XState, React & TypeScript

Modern UI development is full of invisible complexity: async flows, conflicting states, edge cases, and fragile logic spread across useEffects and booleans.

This series is about doing it differently.

By modeling your UI behavior with state machines and statecharts, you can write code that’s:

Easier to understand

Safer to extend

Visually predictable

Naturally testable

Easy to Maintain and Refactor

Through weekly posts, hands-on code examples, and short video breakdowns, you’ll learn how to build state-driven UIs using tools like XState, React, TypeScript and even Vanilla JS — from the fundamentals to real-world patterns like forms, modals, async data, and more.

Whether you’re just curious about state machines or want to build your next app with them from the ground up, this is your guide to building interfaces that don't fall apart.
