Bunia

A minimalist fullstack framework — SSR · Svelte 5 Runes · Bun · ElysiaJS.

File-based routing inspired by SvelteKit, built on top of the Bun runtime and ElysiaJS HTTP server. No Node.js, no Vite, no adapters.

Features

• File-based routing — +page.svelte, +layout.svelte, +server.ts, route groups, dynamic segments, catch-all routes
• Server-side rendering — every page is rendered on the server with full hydration
• Server loaders — +page.server.ts and +layout.server.ts with parent() data threading
• API routes — +server.ts exports HTTP verbs (GET, POST, PUT, PATCH, DELETE, OPTIONS)
• Middleware hooks — hooks.server.ts with sequence() for auth, logging, locals
• Dev server with HMR — file watcher + SSE browser reload, no page blink
• Tailwind CSS v4 — compiled at build time, shadcn-inspired design tokens out of the box
• CLI — bunia create, bunia dev, bunia build, bunia add, bunia feat
