Introduction to State Machines Using XState
Kyle Shevlin
- xstate
>=4.6.7 - javascript
The difficulty of managing state is one of the primary reasons our applications become so complex. We try and manage this complexity with a lot of booleans, somewhat semantic variables like isLoading, wasFetched, and hasError, and over-engineered systems that are still full of bugs. Surely, there's a better way.
That better way is state machines.
State machines formalize how we define and transition through the states of our application and give us ultimate control of the most complex parts of our apps.
In this course, we will explore the problems state machines purport to solve, like boolean explosion. We'll try to solve it our own way first, get so far, and then demonstrate how state machines get us all the way. After that, we'll dive into the XState library, JavaScript's premiere state machine library, to learn its API and how to use it to solve our problems.
By the time you're done taking this course, you should have a solid education about state machines and be able to start applying them.

- What did you like about this course?
I'm new to xstate and it was a great intro in such a great tool. Thanks

This is a insightful course if you know basic theory of machines (in the mathematical sense)
Juan Camacho4 years ago - What did you like about this course?
Really detailed and easygoing introduction to XState. The official docs are pretty good but look a bit daunting at first. This course makes onboarding the XState train easier and faster! Now that I know what XState allows me doing, I can navigate through the official docs way better. Thanks for the course, Kyle!
