Plugin and Configuration

voidPlugin(options?)

Named export from "void". Returns an array of Vite plugins that set up file-based routing, migration support, and the Cloudflare Workers runtime. Application-level configuration is read from void.config.ts; the optional options object controls Vite/Cloudflare plugin behavior.

import { voidPlugin } from 'void';

export default defineConfig({
  plugins: [voidPlugin()],
});

Option	Type	Description
persistTo	string	Directory path for persisting local dev state (D1, KV, R2). Defaults to .void/ in the project root.
auxiliaryWorkers	AuxiliaryWorkerConfig[]	Additional workers to run inside the same Miniflare instance during dev. Passed through to @cloudflare/vite-plugin. Useful for running multiple workers that share bindings (e.g. a separate API worker alongside a dashboard).

Project configuration

defineConfig(config)

Import from void/config in the root void.config.ts. It returns the config with editor completion and TypeScript checking. Void validates the result when loading it, including values computed at runtime.

import { defineConfig } from 'void/config';

export default defineConfig({
  cloudflare: { name: 'my-app' },
  routing: { revalidate: 60 },
});

See the config reference for all fields.
