svelte-adapter-firebase

• Purpose: The library is a Firebase adapter for SvelteKit, enabling SSR on Cloud Functions while leveraging Firebase Hosting for static assets. It integrates SvelteKit apps with Firebase's infrastructure.
• Key Features:
  • SSR on Cloud Functions
  • Integration with existing Cloud Functions
  • Local testing via Firebase Emulator
  • Cold-start mitigation with minInstances
  • Support for multiple Hosting sites
• Target Audience: Developers using SvelteKit who want to deploy their apps on Firebase with SSR capabilities.
• Svelte Support: Explicitly designed for SvelteKit, making it a primary framework for this adapter.
• How It Works:
  • Static assets are deployed to Firebase Hosting.
  • SSR logic is bundled into Cloud Functions, with rewrite rules directing requests to these functions.
  • Configuration is driven by firebase.json, with adapter options for customization.
• Caveats:
  • Firebase's first-party SvelteKit support may deprecate this adapter in the future.
  • Cloud Function rewrites only support the us-central1 region.
  • Firebase Hosting Preview Channels lack SSR support.
• Non-Goals:
  • Automatically writing Cloud Function code to files (manual integration is required).
  • Handling Firebase deployments (left to the user).
• FAQ: Addresses common questions like cold starts, Firebase SDK usage, and manual Cloud Function code integration.
