relay

Relay lets developers specify data requirements declaratively using GraphQL, automatically handling fetching, caching, and updates, as highlighted in the README's 'Declarative' section, reducing imperative boilerplate code.

By keeping GraphQL queries alongside React components, Relay improves code organization and maintainability, making it easier to reason about data dependencies, as noted in the 'Colocation' feature.

Relay aggregates multiple queries into efficient network requests, minimizing overhead and fetching only necessary data, which enhances performance for data-driven applications, as described in the key features.

Provides built-in support for GraphQL mutations with optimistic updates, error handling, and automatic data consistency, ensuring smooth user experiences during data changes, as emphasized in the 'Mutations' section.
