SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires jq, and includes references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide for building SvelteKit applications as pure Single Page Applications (SPA) with client-side rendering, specifically optimized for integration with separate backends like Golang/Echo, simplifying frontend development without SSR complexities.

Core Features & Use Cases

  • SPA Configuration: Configure adapter-static with fallback pages and globally disable SSR/prerendering for a pure client-side experience.
  • Client-Side Routing & Data Loading: Leverage SvelteKit's file-based routing and +page.ts load functions for efficient client-side data fetching from external APIs.
  • Authentication & Security: Guidance on authentication token flows, HttpOnly cookies, and proper CORS configuration for secure backend integration.
  • Performance Optimization: Implement prefetching strategies, code splitting, selective prerendering, and request deduplication for a fast user experience.
  • Backend Integration Patterns: Detailed examples for Golang/Echo backend setup, API client utilities, file uploads, and WebSocket integration.
  • Use Case: Develop a SvelteKit frontend for a Golang/Echo REST API, handling user login, protected routes, dynamic data fetching, and deploying as a static SPA.

Quick Start

Use the sveltekit-spa skill to configure my SvelteKit project for SPA mode with adapter-static and disable SSR globally in src/routes/+layout.ts.

Frequently Asked Questions about sveltekit-spa

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a SvelteKit single page application without server-side rendering?▼

Configure SvelteKit with adapter-static and disable SSR globally in src/routes/+layout.ts by setting export const ssr = false. This routes all rendering to the client and enables pure SPA mode with client-side data fetching from external APIs.

Can I use SvelteKit with a separate Golang or Echo backend API?▼

Yes. SvelteKit SPA mode integrates seamlessly with separate backends like Golang/Echo. Use +page.ts load functions for client-side API calls, configure environment-based endpoints, and implement proper CORS and authentication token flows for secure communication.

What's the best way to handle client-side routing and data loading in a SvelteKit SPA?▼

Leverage SvelteKit's file-based routing with +page.ts load functions to fetch data client-side. This approach enables efficient code splitting, request deduplication, and dynamic data loading without server involvement.

Do I need to migrate from SvelteKit SSR to client-side rendering, and how?▼

Yes, migration is supported. Disable SSR globally, switch to adapter-static with an appropriate fallback page, and refactor data loading to use client-side +page.ts functions instead of server-side load functions.

How do I secure authentication and protect routes in a SvelteKit SPA with an external backend?▼

Implement HttpOnly cookie authentication or token-based flows with CORS-enabled backend endpoints. SvelteKit SPA mode supports client-side route guards and authentication checks using load functions before rendering protected pages.

What performance optimizations are available for SvelteKit SPAs with static adapters?▼

Implement prefetching strategies, code splitting via dynamic imports, selective prerendering for critical pages, and request deduplication in load functions to minimize network calls and deliver a fast user experience.
