vercel-composition-patterns

React composition patterns that scale. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or designing reusable APIs. Triggers on tasks involving compound components, render props, context providers, or component architecture. Includes React 19 API changes.

React Composition Patterns


Composition patterns for building flexible, maintainable React components. Avoid

boolean prop proliferation by using compound components, lifting state, and

composing internals. These patterns make codebases easier for both humans and AI

agents to work with as they scale.


When to Apply


Reference these guidelines when:


  • •Refactoring components with many boolean props
  • •Building reusable component libraries
  • •Designing flexible component APIs
  • •Reviewing component architecture
  • •Working with compound components or context providers

    • Rule Categories by Priority


    | Priority | Category | Impact | Prefix |

    | -------- | ----------------------- | ------ | --------------- |

    | 1 | Component Architecture | HIGH | architecture- |

    | 2 | State Management | MEDIUM | state- |

    | 3 | Implementation Patterns | MEDIUM | patterns- |

    | 4 | React 19 APIs | MEDIUM | react19- |


    Quick Reference


    1. Component Architecture (HIGH)


  • •architecture-avoid-boolean-props - Don't add boolean props to customize

    • behavior; use composition

  • •architecture-compound-components - Structure complex components with shared

    • context


    2. State Management (MEDIUM)


  • •state-decouple-implementation - Provider is the only place that knows how

    • state is managed

  • •state-context-interface - Define generic interface with state, actions, meta

    • for dependency injection

  • •state-lift-state - Move state into provider components for sibling access

    • 3. Implementation Patterns (MEDIUM)


  • •patterns-explicit-variants - Create explicit variant components instead of

    • boolean modes

  • •patterns-children-over-render-props - Use children for composition instead

    • of renderX props


    4. React 19 APIs (MEDIUM)


    > ⚠️ React 19+ only. Skip this section if using React 18 or earlier.


  • •react19-no-forwardref - Don't use forwardRef; use use() instead of useContext()

    • How to Use


    Read individual rule files for detailed explanations and code examples:


    rules/architecture-avoid-boolean-props.md

    rules/state-context-interface.md


    Each rule file contains:


  • •Brief explanation of why it matters
  • •Incorrect code example with explanation
  • •Correct code example with explanation
  • •Additional context and references

    • Full Compiled Document
