Learn how Attio's TypeScript codebase handles errors and loading in a type-safe, functional inspired way.

We all love using TypeScript but sometimes the try/catch loop gets too complicated. Let's see how we can leverage the type system that Rust uses to make our errors look cleaner and better.

When it comes to composing business logic into services, we've had our fair share of how to do, structure, organize, and call them from within our application. It's especially difficult without opinionated frameworks and the (not so great) native error handling of JavaScript. Especially when it comes to Promises. In my talk, discover how to structure services that gracefully handle errors (with type safety), how to work with promises in a predictable way and how monads can make your life easier.

About Joe: I'm a Lead Software Engineer and a huge DX enthusiast since everybody seems to only care about UX (what about us? 😢) I've started working with TypeScript around 3-4 years ago and I'm not sure whether that's a good thing or not 🙃.

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.
