tsnapi is a developer‑focused tool that captures a library’s public contract—both its runtime exports and TypeScript declaration files—into human‑readable snapshot files stored alongside the code. Integrated as a Rolldown/tsdown plugin, a CLI, or a Vitest helper, it automatically flags unintended API changes (or confirms intentional ones via an update flag), making it ideal for maintainers of JavaScript/TypeScript packages and monorepos who want reliable regression testing of their public API surface.
