How I Added Pre-Rendering to a Vite Multi-Page App Without SSR

Short summary

The author solved SEO crawler issues on a 1,449-page Vite multi-page app by creating a custom build-time plugin that injects SEO content (H1 tags, meta descriptions, FAQs) into static HTML—avoiding the need for full server-side rendering while maintaining static hosting on Cloudflare Pages. The lightweight solution handles 25+ languages with negligible build overhead (~0.3s), enabling crawlers to index content on first pass while JavaScript runtime replaces it with interactive UI.
