SolidJS Best Practices Comprehensive guide for building high-performance web applications with SolidJS, featuring fine-grained reactivity, signals, and optimized rendering. State Management with Stores Creating and Using Stores Implement global state with stores Use context for dependency injection Create reactive store patterns Example store implementation: Resource Pattern for Data Fetching Use createResource for async data fetching Implement proper loading and error states Handle data refetching and caching Example resource patterns: Performance Optimization Compilation and Bundle Optimization Leverage SolidJS's compile-time optimizations Use lazy loading for code splitting Implement proper bundling strategies Example optimization techniques: Memory Management and Cleanup Properly clean up effects and subscriptions Use onCleanup for resource disposal Handle component unmounting gracefully Example cleanup patterns: Summary Checklist [ ] Use signals for reactive state management [ ] Leverage createMemo for derived computations [ ] Implement proper component composition with splitProps [ ] Use SolidJS control flow components (Show, For, Switch) [ ] Create stores for global state management [ ] Use createResource for async data fetching [ ] Implement client-side routing with Solid Router [ ] Use lazy loading for code splitting and performance [ ] Properly clean up effects and subscriptions [ ] Write comprehensive tests for components and stores [ ] Optimize bundle size with tree shaking [ ] Handle error boundaries and loading states [ ] Use TypeScript for better development experience [ ] Implement proper accessibility patterns Follow these practices to build high-performance, reactive web applications with SolidJS's fine-grained reactivity system.
