+
+## Before You Start
+
+**Open a GitHub Issue before writing code.** This is the preferred way to propose any change. It lets maintainers and the community align on the approach before time is spent on implementation. If you have discussed a contribution in the [Discord server](https://discord.com/invite/952SFk8Tb8) instead, include a link to the relevant Discord thread in your pull request. Pull requests submitted without a corresponding issue or Discord discussion may be closed.
+
+**Unsolicited architectural changes will be closed.** The internal architecture of bknd is intentional. Refactors, restructuring, or changes to core patterns must be discussed and approved before any code is written.
+
+Contributions that are generally welcome (after opening an issue):
+
+- Bug fixes
+- New adapters, strategies, or storage backends
+- Documentation improvements
+- New examples
+- Test coverage improvements
+
+**A note on versioning**: bknd is pre-1.0 and under active development. Full backward compatibility is not guaranteed before v1.0.0. Contributors should be aware that APIs and internal interfaces may change between releases.
+

+
+## Development Setup
+
+### Prerequisites
+
+- Node.js 22.13 or higher
+- Bun 1.3.3
+
+### Getting Started
+
+1. Fork the repository and clone your fork.
+
+2. Install dependencies from the repo root:
+
+   ```bash
+   bun install
+   ```
+
+3. Navigate to the main app package:
+
+   ```bash
+   cd app
+   ```
+
+4. Copy the example environment file:
+
+   ```bash
+   cp .env.example .env
+   ```
+
+   The default `.env.example` includes a file-based SQLite database (`file:.db/dev.db`). You can change `VITE_DB_URL` to `:memory:` for an in-memory database instead.
+
+5. Start the dev server:
+
+   ```bash
+   bun run dev
+   ```
+
+   The dev server runs on `http://localhost:28623` using Vite with Hono.
+
+## Project Structure
+
+This is a Bun monorepo using workspaces. The vast majority of the code lives in `app/`.
+
+```

+
+## Understanding the Codebase
+
+### Path Aliases
+
+The project uses TypeScript path aliases defined in `app/tsconfig.json`. Imports like `core/utils`, `data/connection`, or `auth/authenticate` resolve to directories under `app/src/`. When reading source code, keep this in mind -- an import like `import { Connection } from "data/connection"` refers to `app/src/data/connection`, not an external package.
+
+### Module System
+
+bknd is built around four core modules, each with its own schema, API routes, and permissions:
+
+- **Data** -- entity definitions, field types, relations, queries (backed by Kysely)
+- **Auth** -- authentication strategies, sessions, user management
+- **Media** -- file storage with pluggable adapters (S3, Cloudinary, local filesystem, etc.)
+- **Flows** -- workflow automation and task execution
+
+These modules are managed by the `ModuleManager` (in `app/src/modules/`), which handles configuration, building, and lifecycle.
+
+### Adapter Pattern
+
+Adapters in `app/src/adapter/` allow bknd to run on different runtimes and frameworks. Each adapter provides the glue between bknd's Hono-based server and a specific environment (Node, Bun, Cloudflare Workers, Next.js, Astro, etc.).
+
+### Plugin System
+
+Plugins (in `app/src/plugins/`) hook into the app lifecycle via callbacks like `beforeBuild`, `onBuilt`, `onServerInit`, and `schema`. They can add entities, register routes, and extend behavior.
+
+### Build System
+
+The build is handled by a custom `app/build.ts` script using tsup (esbuild under the hood). It builds four targets in parallel:
+
+- **API** -- the core backend
+- **UI** -- the admin interface
+- **Elements** -- standalone React components
+- **Adapters** -- all runtime/framework adapters
+
+## Running Tests
+
+All test commands run from the `app/` directory.
+
+| Command | Runner | What it runs |
+|---|---|---|
+| `bun run test` | Bun test | Unit tests (`*.spec.ts` files) |
+| `bun run test:node` | Vitest | Node-specific tests (`*.vi-test.ts`, `*.vitest.ts`) |
+| `bun run test:e2e` | Playwright | End-to-end tests (`*.e2e-spec.ts` in `e2e/`) |
+| `bun run types` | TypeScript | Type checking (no emit) |
+
+CI runs both Bun and Node tests, with a Postgres 17 service for database integration tests.
+
+## Code Style
+
+The project uses **Biome** for formatting and linting.
+
+- 3-space indentation for JavaScript/TypeScript
+- 100-character line width
+- Spaces (not tabs)
+
+To format and lint, run from the repo root:
+
+```bash
+bunx biome format --write ./app
+bunx biome lint --changed --write ./app
+```
+
+Run both before submitting a PR. CI will catch style issues, but it is better to fix them locally first.
+
+## Submitting Changes
+
+1. Open a GitHub Issue describing your proposed change, or link to a Discord thread where it was discussed. Wait for feedback before writing code.
+2. Fork the repo and create a branch from `main`.
+3. Keep changes focused and minimal. One PR per issue.
+4. Add or update tests if applicable.
+5. Run the test suite and linter before pushing.
+6. Open a pull request against `main`. Reference the issue number in the PR description.
+
+Expect a response from maintainers, but be patient -- this is an actively developed project and review may take some time.
+
+## AI-Generated Code
+
+If you use AI tools to write or assist with your code, you must:
+
+- **Fully review all AI-generated code yourself** before submitting. You are responsible for understanding and standing behind every line in your PR.
+- **Include the prompts used** in the PR description. This gives maintainers additional context for reviewing the code.
+
+Pull requests with unreviewed AI-generated code will be closed.
+
+## Contributing to Documentation
+
+The documentation site lives in the `docs/` directory and is a **separate Next.js application** built with [Fumadocs](https://fumadocs.dev). It uses **npm** (not Bun) as its package manager.
+
+### Docs Setup
+
+```bash
+cd docs
+npm install
+npm run dev
+```
+
+The docs dev server runs on `http://localhost:3000`.
+
+### Where Documentation Lives
+
+Documentation content is written in MDX and located in `docs/content/docs/`. The directory is organized into:
+
+- `(documentation)/` -- core documentation pages
+- `guide/` -- guides and tutorials
+- `api-reference/` -- API reference (partially auto-generated from OpenAPI)
+
+To add or edit a page, create or modify an `.mdx` file in the appropriate directory. Page metadata is defined via frontmatter at the top of each file. Navigation order is controlled by `meta.json` files in each directory.
+
+### Building the Docs
+
+```bash
+npm run build
+```
+
+This generates the OpenAPI and MCP reference pages before building the Next.js site. Make sure the build succeeds locally before submitting a docs PR.
+
+## Reporting Bugs
+
+Open a GitHub Issue with:
+
+- A clear title describing the problem.
+- Steps to reproduce the bug.
+- Expected behavior vs. actual behavior.
+- Your environment (runtime, database, adapter, bknd version).
+- Any relevant error messages or logs.
+

+title: "Tanstack Start"
+description: "Run bknd inside Tanstack Start"
+tags: ["documentation"]
+---
+
+## Installation
+
+To get started with Tanstack Start and bknd, create a new Tanstack Start project by following the [official guide](https://tanstack.com/start/latest/docs/framework/react/getting-started#start-a-new-project-from-scratch), and then install bknd as a dependency:
+
+<Tabs groupId='package-manager' persist items={[ 'npm', 'pnpm', 'yarn', 'bun']}>
+
+```bash tab="npm"
+npm install bknd
+```
+
+```bash tab="pnpm"
+pnpm install bknd
+```
+
+```bash tab="yarn"
+yarn add bknd
+```
+
+```bash tab="bun"
+bun add bknd
+```
+
+</Tabs>
+
+## Configuration
+
+<Callout type="warning">
+  When run with Node.js, a version of 22 (LTS) or higher is required. Please
+  verify your version by running `node -v`, and
+  [upgrade](https://nodejs.org/en/download/) if necessary.
+</Callout>
+
+Now create a `bknd.config.ts` file in the root of your project:
+
+```typescript title="bknd.config.ts"
+import { type TanstackStartConfig } from "bknd/adapter/tanstack-start";
+import { em, entity, text, boolean } from "bknd";
+
+const schema = em({
+  todos: entity("todos", {
+    title: text(),
+    done: boolean(),
+  }),
+});
+
+export default {
+  connection: {
+    url: "file:data.db",
+  },
+  config: {
+    data: schema.toJSON(),
+    auth: {
+      enabled: true,
+      jwt: {
+        secret: "random_gibberish_please_change_this",
+        // use something like `openssl rand -hex 32` for production
+      },
+    },
+  },
+  options: {
+    // the seed option is only executed if the database was empty
+    seed: async (ctx) => {
+      // create some entries
+      await ctx.em.mutator("todos").insertMany([
+        { title: "Learn bknd", done: true },
+        { title: "Build something cool", done: false },
+      ]);
+
+      // and create a user
+      await ctx.app.module.auth.createUser({
+        email: "test@bknd.io",
+        password: "12345678",
+      });
+    },
+  },
+} satisfies TanstackStartConfig;
+```
+
+For more information about the connection object, refer to the [Database](/usage/database) guide.
+
+
+See [bknd.config.ts](/extending/config) for more information on how to configure bknd. The `TanstackStartConfig` type extends the base config type with the following properties:
+
+```typescript
+export type TanstackStartConfig<Env = TanstackStartEnv> = FrameworkBkndConfig<Env>;
+```
+
+## Serve the API
+
+The Tanstack Start adapter uses Tanstack Start's hooks mechanism to handle API requests. Create a `/src/routes/api.$.ts` file:
+
+```typescript title="/src/routes/api.$.ts"
+import { createFileRoute } from "@tanstack/react-router";
+import config from "../../bknd.config";
+import { serve } from "bknd/adapter/tanstack-start";
+

+  server: {
+    handlers: {
+      ANY: async ({ request }) => await handler(request),
+    },
+  },
+});
+```
+
+Create a helper file to instantiate the bknd instance and retrieve the API, importing the configuration from the `bknd.config.ts` file:
+
+```ts title="src/bknd.ts"
+import config from "../bknd.config";
+import { getApp } from "bknd/adapter/tanstack-start";
+
+export async function getApi({
+  headers,
+  verify,
+}: {
+  verify?: boolean;
+  headers?: Headers;
+}) {
+  const app = await getApp(config, process.env);
+
+  if (verify) {
+    const api = app.getApi({ headers });
+    await api.verifyAuth();
+    return api;
+  }
+
+  return app.getApi();
+};
+```
+
+<Callout type="info">
+  The adapter uses `process.env` to access environment variables, this works because Tanstack Start uses Nitro underneath and it will use polyfills for `process.env` making it platform/runtime agnostic.
+</Callout>
+
+## Enabling the Admin UI
+
+Create a page at /src/routes/admin.$.tsx:
+
+```typescript title="/src/routes/admin.$.tsx"
+import { createFileRoute } from "@tanstack/react-router";
+import { useAuth } from "bknd/client";
+import "bknd/dist/styles.css";
+import { Admin } from "bknd/ui";
+
+export const Route = createFileRoute("/admin/$")({
+  ssr: false, // [!code highlight] "data-only" works too
+  component: RouteComponent,
+});
+
+function RouteComponent() {
+  const { user } = useAuth();
+  return (
+    <Admin
+      withProvider={{ user: user }}
+      config={{
+        basepath: "/admin",
+        logo_return_path: "/../",
+        theme: "system",
+      }}
+      baseUrl={import.meta.env.APP_URL}
+    />
+  );
+};
+```
+
+<Callout type="info">
+  Admin routes are expected to run on the client not using `ssr: false` will cause errors like `✘ [ERROR] No matching export in "node_modules/json-schema-library/dist/index.mjs" for import "Draft2019"` and production build might fail because of this
+</Callout>
+
+
+## Example usage of the API
+
+You can use the `getApp` function to access the bknd API in your app:
+These are a few examples how you can validate user and handle server-side requests using `createServerFn`.
+
+```typescript title="src/routes/index.tsx"
+import { createFileRoute } from "@tanstack/react-router";
+import { getApi } from "@/bknd";
+import { createServerFn } from "@tanstack/react-start";
+
+export const getTodo = createServerFn()
+  .handler(async () => {
+    const api = await getApi({});
+    const limit = 5;
+    const todos = await api.data.readMany("todos", { limit, sort: "-id" });
+    return { todos };
+  });
+
+export const Route = createFileRoute("/")({
+  ssr: false,
+  component: App,
+  loader: async () => {
+    return await getTodo();
+  },
+});
+
+function App() {
+  const { todos } = Route.useLoaderData();
+
+  return (
+    <div>
+      <h1>Todos</h1>
+      <ul>
+        {todos.map((todo) => (
+          <li key={todo.id}>{todo.title}</li>
+        ))}
+      </ul>
+    </div>
+  );
+}
+```
+
+
+
+### Using authentication
+
+To use authentication in your app, pass the request headers to the API:
+
+```typescript title="src/routes/user.tsx"
+import { getApi } from "@/bknd";
+import { createServerFn } from "@tanstack/react-start";
+import { Link } from "@tanstack/react-router";
+import { createFileRoute } from "@tanstack/react-router";
+import { getRequest } from "@tanstack/react-start/server";
+
+export const getUser = createServerFn()
+  .handler(async () => {
+    const request = getRequest();
+    const api = await getApi({ verify: true, headers: request.headers });
+    const user = api.getUser();
+    return { user };
+  });
+
+export const Route = createFileRoute("/user")({
+  component: RouteComponent,
+  loader: async () => {
+    return { user: await getUser() };
+  },
+});
+
+function RouteComponent() {
+  const { user } = Route.useLoaderData();
+  return (
+    <div>
+      {user ? (
+        <>
+          Logged in as {user.email}.{" "}
+          <Link
+            className="font-medium underline"
+            to={"/api/auth/logout" as string}
+          >
+            Logout
+          </Link>
+        </>
+      ) : (
+        <div className="flex flex-col gap-1">
+          <p>
+            Not logged in.
+            <Link
+              className="font-medium underline"
+              to={"/admin/auth/login" as string}
+            >
+              Login
+            </Link>
+          </p>
+          <p className="text-xs opacity-50">
+            Sign in with:
+            <b>

+# bknd + Tanstack Start Example
+
+This is a minimal example to shows how to integrate bknd with Tanstack Start.
+
+## Setup
+
+```bash
+bun install
+bun run dev
+```
+
+## How it works
+
+1. **`bknd.config.ts`** - bknd configuration with database connection, schema, and seed data
+2. **`src/routes/api.$.ts`** - Handles `/api/*` requests for bknd
+3. **`src/routes/index.tsx`** - Using `getApp()` to fetch data in loader
+3. **`src/routes/ssr.tsx`** - Server Side example with `getApp()` to fetch data on server
+
+## API Endpoints
+
+- `GET /admin` - for Admin Dashboard
+- `GET /api/data/entity/todos` - List todos (requires auth)
+- `POST /api/auth/password/login` - Login
+
+## Test Credentials
+
+- Email: `test@bknd.io`
+- Password: `12345678`
