tkdodo.eu is the personal blog of Dominik Dorfmeister, a web developer from Vienna with a strong focus on React and TypeScript. Dominik is a co-maintainer of TanStack Query, one of the most popular async state management libraries in the React ecosystem, where he focuses on education, support, and explaining complex concepts in an approachable way. On his blog he writes in depth articles about React, TypeScript, React Query, async state management, and practical frontend patterns. Many posts are based on real questions from the community on Twitter, Stack Overflow, and the TanStack Discord, which makes the content very close to what developers struggle with in day to day work. He also helps maintain remeda, a TypeScript focused utility library, and often shows how strong typing and good tooling can make React apps safer and easier to maintain.
