Install
npm install @flighthq/requirement
Import the supported application-facing API from @flighthq/requirement. The @flighthq/requirement/contract export is the wider package-to-package contract used to compose Flight itself.
This package is part of the locked-version Flight SDK graph. Applications may instead install and import @flighthq/sdk when package-level tree shaking is sufficient.
