> Reaction Commerce is an open-source, API-first, headless commerce platform
> built with Node.js, React and GraphQL, deployed via Docker and Kubernetes.
> Acquired by Mailchimp in 2020 and rebranded Mailchimp Open Commerce, the core
> platform is now discontinued but its developer documentation and npm packages
> remain published. The API is GraphQL and self-hosted; a default local instance
> exposes its endpoint at http://localhost:3000/graphql.
