Flowtyped for npmjs.com is a free Chrome extension designed to enhance the way developers interact with npm packages. This tool specifically focuses on Flow types, providing visual indicators that help users quickly identify whether a library includes Flow type definitions. It displays a yellow Flow icon next to packages that ship with Flow definitions, and a blue Flow icon for those with definitions available through the flow-typed GitHub repository.

This extension complements the existing TypeScript indicators already present on npmjs.com, streamlining the process for developers who prefer using Flow for type checking. By integrating these visual cues directly into the npm package information, Flowtyped for npmjs.com makes it easier for users to make informed decisions about the libraries they choose to incorporate into their projects.
