What is Void? ​

Void is a fullstack SDK for Vite apps. It connects your server code, database, and frontend types, and deploys your app to Cloudflare Workers. To try it, start with the Quickstart.

Add the Vite plugin to your app. As you use features such as a database, key-value storage, or queues, Void detects what you need and sets up the corresponding resources.

The CLI and build tools require Node.js 24.21.0 or later.

sh
npm install -D vite void
ts
import { defineConfig } from 'vite';
import { voidPlugin } from 'void';

export default defineConfig({
  plugins: [voidPlugin()],
});
sh
void init   # choose your framework and deployment target
void deploy

The idea ​

Your code often already describes the resources it needs. Import db from void/db, for example, and Void provides a database for local development and provisions its production resource when you deploy. The same pattern applies to kv, storage, queues, and AI.

Types follow your data through the app: from a Drizzle schema to a route handler, then to the frontend calling that route. You can change a field in one place and let TypeScript show you the code that needs updating.

Void brings these pieces together:

  • Resources from your code: imports tell Void which supported resources to provision. Use void.json or your Cloudflare config when you need to customize them.
  • Types from database to frontend: your Drizzle schema defines DB types, route handlers infer return types, and the typed fetch client checks calls at the usage site. One Standard Schema validator can drive both runtime validation and compile-time types.
  • Local Cloudflare development: native Void apps run server code in workerd, with local database, KV, and storage.
  • Deploy that understands the app: void deploy reads your migrations, provisions the resources you actually use, and ships the result to the edge.

The platform ​

Void deploys to Cloudflare Workers. You can use your own Cloudflare account or connect to a Void platform managed by your team. Both use the same SDK and CLI.

Static assets are cached at the edge. Prerendering builds pages ahead of time, while incremental revalidation caches pages rendered on demand. Database, storage, secrets, and deployment commands are available through Void.

For a single app, deploy to your own account. To give a team a shared deployment service, install a Void platform, then let developers connect to its URL.

How it works ​

vite.config.ts                →  voidPlugin() (works with any Vite app)
import { db }                 →  D1 database (auto-provisioned)
import { kv }                 →  KV namespace (auto-provisioned)
import { storage }            →  R2 bucket (auto-provisioned)
import { ai }                 →  Workers AI inference (metered)
db/schema.ts                  →  Drizzle schema (source of truth for DB types)
db/migrations/*.sql           →  Applied to D1 on deploy
void deploy                   →  Deploy to the saved Cloudflare or Void target

The plugin scans your source code at build time, detects which imports you use, and provisions the corresponding Cloudflare bindings on deploy.

Void also works with existing frameworks. TanStack Start, React Router, SvelteKit, Nuxt, and Astro can all deploy with the same voidPlugin().

If you are building a full-stack app without a meta-framework, Void also gives you file-based server routing with method exports, dynamic params, middleware, and validation. It also includes pages routing for server-rendered UI, SPA navigation, co-located data loading, and typed forms across React, Vue, Svelte, and Solid.

Void detects your app type and chooses the appropriate build and deployment flow.
