```ts import { defineConfig } from 'vite' import { nitro } from 'nitro/vite' export default defineConfig({ plugins: [nitro()], nitro: { serverDir: "./server" } }) ``` ```ts import { defineConfig } from 'nitro' export default defineConfig({ preset: "node", serverDir: "./server", routeRules: { "/api/**": { cache: true } } }) ``` Build /Servers Nitro extends your Vite application with a production-ready server, compatible with any runtime. Add server routes to your application and deploy many hosting platform with a zero-config experience. File-system routing Create server routes in the routes/ folder and they are automatically registered. Or bring your own framework — H3, Hono, Elysia, Express — via a server.ts entry. Deploy everywhere The same codebase deploys to Node.js, Cloudflare Workers, Deno, Bun, AWS Lambda, Vercel, Netlify, and more — zero config, no vendor lock-in. Universal storage Built-in key-value storage abstraction powered by unstorage. Works with filesystem, Redis, Cloudflare KV, and more — same API everywhere. Built-in caching Cache route handlers and arbitrary functions with a simple API. Supports multiple storage backends and stale-while-revalidate patterns. Web standard server Go full Web standard and pick the library of your choice. Use H3, Hono, Elysia, Express, or the raw fetch API — Nitro handles the rest. Universal renderer Use any frontend framework as your renderer. Nitro provides the server layer while your framework handles the UI. Server plugins Extend Nitro's runtime behavior with plugins. Hook into lifecycle events, register custom logic, and auto-load from the plugins/ directory. Built-in database Lightweight SQL database layer powered by db0. Pre-configured with SQLite out of the box, with support for PostgreSQL, MySQL, and Cloudflare D1. Static & server assets Serve public assets directly to clients or bundle server assets for programmatic access. Works seamlessly across all deployment targets.
