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 🙃.

Michael works on JavaScript Infrastructure at Bloomberg and is a TypeScript contributor. This talk will look at the core principles to consider when building great CLI applications, and how TypeScript can be used to make this a breeze.

When writing a fullstack application a common problem facing developers today is keeping data consistency between the frontend and backend. What the backend expects and what the frontend sends is not always the same.

In this talk we’ll look at this problem and different approaches to solve it. We’ll take a look at how AWS Amplify approaches this problem and show a demo. We’ll also compare and contrast other TypeScript approaches with React and Next.
