All Vercel trails
  1. New features for SvelteKit: Optimize your application with easeThis post details the integration of SvelteKit with Vercel's Framework-Defined Infrastructure (FDI), enabling per-route configuration for Serverless and Edge Functions, Incremental Static Regeneration (ISR), and compatibility with Vercel products. It highlights SvelteKit's adapter system for platform-agnostic deployments and explains how to configure ISR with expiration times and bypass tokens in `page.server.js`. It also mentions Vercel's data solutions (Edge Config, KV, Postgres, Blob), preview deployments, and analytics integration for SvelteKit projects.
  2. Using SvelteKit 1.0 on VercelThis post announces the launch of SvelteKit 1.0 and details its features such as directory-based routing, layouts, the `load` function for data fetching, and server routes (endpoints). It also highlights the benefits of deploying SvelteKit on Vercel, including zero-configuration deployment and the use of Edge Functions for dynamic rendering.
  3. The future of Svelte, an interview with Rich HarrisThis interview with Rich Harris, creator of Svelte, discusses the future of Svelte and SvelteKit. Key points include the benefits of joining Vercel for open-source projects (funding, community growth), selling SvelteKit to leadership (shipping faster), and SvelteKit's edge-first design philosophy. It highlights how SvelteKit's framework design optimizes for running code close to customers, leveraging Vercel's File System API and Edge Network for performance.
