Relay Mutation Patterns

About

This skill provides Claude with expert-level knowledge of Relay's mutation system, enabling the development of high-performance, interactive React applications. It covers essential patterns for declarative cache updates using directives like @appendEdge, manual store manipulations with ConnectionHandler, and robust error handling strategies. By leveraging these patterns, developers can build seamless user experiences with instant UI feedback via optimistic responses and maintain reliable data consistency across the normalized Relay environment.

Key Features

• Advanced optimistic UI patterns for immediate user feedback
• Manual cache manipulation using the Relay Store and ConnectionHandler
• Comprehensive mutation lifecycle management using useMutation and commitMutation
• Structured error handling for GraphQL and network-level failures
• Declarative connection updates with @appendEdge and @prependEdge
• 72 GitHub stars

Use Cases

• Building real-time social feeds where new posts appear instantly in connections
• Developing robust form submissions with sophisticated validation and rollback logic
• Implementing complex 'Like' or 'Vote' systems with optimistic state management
