To expose a VTEX IO React component as a Store Framework block, you must map and register it within the interfaces.json file, ensuring that frontmatter metadata and block contract definitions are properly configured for theme-level composition.

Block registration in VTEX IO is the process of wiring React components to Store Framework blocks via interfaces.json. This mapping connects component identifiers to theme configurations, enabling runtime rendering and storefront composition.

Defining allowed children for VTEX IO blocks requires specifying block contracts and composition rules within your component interfaces. This configuration ensures that the registered blocks render correctly within the storefront theme hierarchy.

A VTEX IO block fails to render when frontmatter metadata, block contract definitions, or interface mappings do not satisfy runtime expectations. Auditing the component exposure and interfaces.json configuration resolves these runtime compatibility issues.

No, VTEX IO blocks require interfaces.json configuration to register components within the Store Framework. Without this mapping, the runtime cannot resolve block contracts or render the components in the storefront theme.

The best way to audit a VTEX IO component for runtime compatibility is to review its block contract definitions, validate the interfaces.json mappings, and ensure frontmatter metadata satisfies Store Framework rendering expectations.
