TypeScript React Libraries: What to Check
Jun 20, 2026 · 5 min read
Built-in types beat community @types for most new React libraries. Here is a quick audit before the package hits your lockfile.
Prefer types in the same package
Look for a types or typings field on npm. Built-in types move with the release. DefinitelyTyped can lag behind a breaking change.
React Library Hub flags TypeScript support from keywords and package metadata so you can filter the grid.
Read the public types, not the README
Open the .d.ts or hover in your editor. If every prop is optional any, the types are theater.
Generic list and form libraries should expose item and field types you can extend without casts.
