A hands-on session working through pernicious React bugs, and how to squash them for good. By working through a concrete Todo List example, we’ll leverage TypeScript and JavaScript features to gradually improve the reliability and performance of our code. We might even push beyond the limit of what’s sensible, inviting a reflexion on the balance of code readability and its runtime performance.

Learn how finite-state machines and reactive programming help us avoid callback hell at Grammarly.
We’ll discuss:

Join us for actionable insights you can apply to your own React applications.

Jazz is a framework for building React apps without a backend. It takes the familiar idea of reactive state and adds real-time sync to the cloud and other users. You can set precise edit permissions on each bit of state right from the client as well, which means that basically all business logic now lives next to your UI. In this talk, we'll see what this looks like in practice by building a multi-user app that also works offline and across devices - in no time.

Effect.ts is TypeScript's "missing standard library": one Effect<Success, Error, Requirements> type covering Rust-style typed errors, concurrency, retries, streams, DI, and schema validation - replacing Zod, Lodash, or RxJS. Composable, type-safe, incrementally adoptable.
