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- |
Quick Reference
1. Component Architecture (HIGH)
architecture-avoid-boolean-props- Avoid boolean mode proliferation;
use explicit variants or 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
