Typst: Designing for Incrementality (Laurenz Mädje at RustWeek)

Laurenz Mädje explains how the Typst compiler was designed from the ground up for incremental compilation to enable real-time document previews.

Typst: Designing for Incrementality by Laurenz Mädje. Typst is sometimes called the love child of Rust and Markdown: A principled programming language married to a lightweight markup language that previews as you type. In this talk, we'll dive deep into the Typst language and its implementation, to see how both are co-designed to achieve real-time preview for large documents. About Laurenz Mädje (he/him): Laurenz is primary maintainer of the Typst language and compiler. He started Typst with a friend during his CS bachelor's, wrote his master's thesis about it, and then went on to co-found the Typst company. Between language design, compiler implementation, and code review, he hacks away at the Typst web app, figuring out why WebKit broke our multi-threaded WebAssembly setup (again). - git: github.com/laurmaedje/ - linkedin: linkedin.com/in/laurmaedje/ - website: laurmaedje.github.io/ This talk was given at RustWeek 2026 as part of the Applied Rust track on Wednesday 20 May.
