I built ErrorScript: TypeScript with "Safe" Exceptions. Unhandled exceptions and dropped promises become part of the type system and raise compile-time errors.

It works. It feels native. And it probably shouldn’t exist.

This talk explores what ErrorScript reveals about how we model failure in code, how language design influences behaviour, and the trade-offs that make this feature unlikely to be adopted.

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.

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.
