Your application probably has thousands of so called "Impossible States" it can walk into. And it's a bummer since that's not what TypeScript is there for! If you're lucky, you've put the right amount of IF statements in the exact places. If not, bugs will start popping up, harming your team's deliveries.

But we can do better!!! Thanks to type-safe State Machines we can get rid of impossible states entirely and make the model consistent. SMs and Signals work together perfectly. Additionally, our state's design becomes first-class citizen of our Angular application.

In this talk we'll use TypeScript's type system to design type-only, library-agnostic State Machines which will guard the values and transitions of app's state, in components and services.

It's one of those talks you can grab the knowledge and immediately use it in your project the next day. You'll love how it's gonna be both: SIMPLE and USEFUL.
