Hydrogen is Shopify’s stack for headless commerce. It provides a set of tools, utilities, and best-in-class examples for building dynamic and performant commerce applications. Hydrogen is designed to dovetail with Remix, Shopify’s full stack web framework, but it also provides a React library portable to other supporting frameworks.

Versioning

Hydrogen and hydrogen-react are tied to specific versions of the Shopify Storefront API, which follows calver.

For example, if you're using Storefront API version 2023-01, then Hydrogen and hydrogen-react versions 2022.1.x are fully compatible.

If the Storefront API version update includes breaking changes, then Hydrogen and hydrogen-react may also include breaking changes. Because the API version is updated every three months, breaking changes could occur every three months.
