relay-fragments-patterns

You can organize and reuse GraphQL data requirements in React components by defining small Relay fragments and composing them to build complex data needs without duplication. This approach standardizes data fetching and reduces the risk of inconsistent queries across your application.

Relay data masking protects data access boundaries by ensuring components can only access the fields explicitly declared in their own fragments. Colocation keeps these data requirements directly within the component files, ensuring predictable data dependencies and efficient fetching.

To create a basic Relay fragment for a Post component, define a fragment that includes fields like id, title, excerpt, publishedAt, and author with name and avatar, then attach this fragment directly to your PostCard component to declare its data dependencies.

Yes, Relay fragments are well-suited for scalable React apps including admin dashboards, content apps, and social feeds. They ensure predictable data dependencies and efficient fetching across complex interfaces by modularizing fragment definitions and composing them.

Relay supports implementing pagination and refetchable fragments within React applications. These fragment patterns allow you to load more data incrementally and refresh existing data, leveraging Relay, GraphQL, and TypeScript tooling for scalable architectures.

You should use Relay fragment composition instead of single large queries when you need modular fragment definitions and colocated data declarations. This standardization reduces duplication, protects data access boundaries, and makes complex data needs easier to manage across components.
