SvelteKit Best Practices Comprehensive guide for building full-stack web applications with SvelteKit, including routing, stores, SSR, and modern development patterns. State Management with Stores Svelte Stores for Global State Use writable stores for mutable state Implement derived stores for computed values Create custom stores for complex logic Example store implementations: Custom Stores for Complex State Create domain-specific stores Implement store composition patterns Handle async operations in stores Example custom store: Store Persistence and Synchronization Persist store state across sessions Sync stores with server state Handle offline scenarios Example persistence patterns: API Routes and Server-Side Logic API Route Implementation Create RESTful API endpoints Handle different HTTP methods Implement proper error handling and validation Example API routes: Authentication and Authorization Hooks Implement server-side authentication Create authorization middleware Handle session management Example authentication setup: Summary Checklist [ ] Use file-based routing for automatic route generation [ ] Implement load functions for server-side data fetching [ ] Create reactive stores for global state management [ ] Use derived stores for computed values [ ] Build reusable components with proper event handling [ ] Implement form validation with reactive statements [ ] Create RESTful API routes with proper error handling [ ] Set up authentication and authorization hooks [ ] Use proper TypeScript types throughout the application [ ] Implement lazy loading and code splitting [ ] Write comprehensive tests for components and stores [ ] Handle loading states and errors gracefully [ ] Use SSR and prerendering for performance [ ] Implement proper SEO and meta tag management Follow these practices to build fast, scalable, and maintainable full-stack web applications with SvelteKit.
