Unleashing TypeScript’s Compiler

Event Logo

Thursday, August 1, 2024 - 7:30 PM UTC, for 1 hour.

Regular, 60 minute presentation

Room: African 50


Let's be honest: manipulating or refactoring a large codebase can sometimes make even the best of us break into a cold sweat. But did you know that TypeScript's Compiler API can be your secret weapon in tackling this challenge? We'll start off by breaking down the key concepts - from the Compiler API and codemods to code formatting - and unveil how they all tie back to the Abstract Syntax Trees (ASTs). Using a real-world example from my work on a Developer Experience team, we'll dive into how we can leverage the TypeScript tooling to our advantage. We'll query our own code to get a clear understanding of scope and then I'll walk you through automating far-reaching changes to your code with confidence, whether that spans hundreds of files or just a handful. In this talk, you'll not only leave with a solid grasp of how to make the TypeScript Compiler API work for you and how to apply that work in a practical way. Let's demystify the ASTs and transform your coding experience!
