TanStack Start

TanStack Start is a Vite-based full-stack React framework. voidPlugin() composes directly with the TanStack Start plugin in the Vite pipeline, so there is no separate adapter to install.

Setup

1. Create a new project

npm create @tanstack/start@latest my-app
cd my-app

2. Install dependencies

npm install -D void

3. Configure vite.config.ts

import { defineConfig } from 'vite';
import { tanstackStart } from '@tanstack/react-start/plugin';
import react from '@vitejs/plugin-react';
import { voidPlugin } from 'void';

export default defineConfig({
  plugins: [
    voidPlugin(), // must come before the framework plugin
    tanstackStart(),
    react(),
  ],
});

4. Deploy

void auth login
void deploy

Using Void Platform Features

Most Void platform features work with TanStack Start. Use them in server functions:

Void-managed auth is not supported in framework mode yet. Use Better Auth's official TanStack Start integration directly for now.

Database

import { createServerFn } from '@tanstack/react-start';
import { db } from 'void/db';
import { users } from '@schema';

const getUsers = createServerFn().handler(async () => {
  return db.select().from(users);
});

KV Storage

import { createServerFn } from '@tanstack/react-start';
import { kv } from 'void/kv';

const getSettings = createServerFn().handler(async () => {
  return kv.get('app:settings');
});

Blob Storage

import { createServerFn } from '@tanstack/react-start';
import { storage } from 'void/storage';

const getAvatar = createServerFn().handler(async () => {
  return storage.get('avatars/user-1.png');
});

AI

import { createServerFn } from '@tanstack/react-start';
import { ai } from 'void/ai';

const summarize = createServerFn().handler(async () => {
  return ai.run('@cf/meta/llama-3.1-8b-instruct', {
    prompt: 'Summarize the latest news',
  });
});

Cron Jobs

// crons/daily-cleanup.ts
import { defineScheduled } from 'void';

export const cron = '0 0 * * *';

export default defineScheduled(async () => {
  // runs daily at midnight
});

Queue Consumers

// queues/emails.ts
import { defineQueue } from 'void';

export default defineQueue<{ to: string; subject: string }>(async (batch) => {
  for (const msg of batch.messages) {
    // process each message
    msg.ack();
  }
});

Environment Variables

Void gives you a typed env layer: declare keys in env.ts, read them via import { env } from "void/env", and get schema validation at build + deploy time plus a client-leak guard that fails the build if a server-only key reaches the browser. See the env vars guide for the full feature set.

Accessing Bindings Directly

You can also access Cloudflare bindings via the cloudflare:workers module:

import { env } from 'cloudflare:workers';

const { results } = await env.DB.prepare('SELECT * FROM users').all();
