# fumadocs-template

This is a Next.js (App Router) application generated with
[Create Fumadocs](https://github.com/fuma-nama/fumadocs) using the **Next.js: Fumadocs MDX** option.

It features basic setup, configurations, sign-in authentication, and tooling to standardize using Fumadocs as a template.

> Next application code lives inside the `/docsapp/src` directory.

### 🎬 Demo

https://fumadocs-template-ten.vercel.app/

### 🎯 Features

- [Fumadocs](https://www.fumadocs.dev/) basic setup
- Public docs pages
- Private docs pages gated by Google sign-in (via Google OAuth)
- Docker setup for local development and production deployment outside Vercel
- ESLint setup

---

### 📋 Requirements

#### 1. NodeJS v24

```text
Recommended version (used within this project)
node v24.11.0
npm v11.6.1
```

#### 2. Google OAuth2 Client (optional)

- This requires a Google Cloud Platform project configured with [OAuth2](https://developers.google.com/workspace/guides/configure-oauth-consent) settings and [credentials](https://developers.google.com/workspace/guides/manage-credentials).
- Read the [GOOGLE_OAUTH.md](/docs/GOOGLE_OAUTH.md) for more information in setting up Google OAuth for sign-in.
- Retrieve the `GOOGLE_CLIENT_ID` and `GOOGLE_CLIENT_SECRET` environment variable values here.
- Add the following in your Google Client ID's **Authorized redirect URIs**:
   - https://<YOUR_DEPLOYED_APP_BASE_URL>/api/auth/callback/google<br>
   - eg., `http://localhost:3000/api/auth/callback/google` (when working in local development)

> [!TIP]
> Setup required only if you want to enable Google sign-in<br>
> To allow unrestricted access on all routes, set `matcher: []` in the `/docsapp/src/proxy.ts` file.

#### 3. Docker (optional)

## 📖 Run development server

#### 1. Navigate to the `/docsapp` directory

```sh
cd docsapp
```

#### 2. Install dependencies.

```sh
npm install
```

#### 3. Run the app

```bash
npm run dev
```

#### 4. Launch the local website.

Open http://localhost:3000 with your browser to see the result.

> [!NOTE]
> Look over the [Ennvironment Variables](#environment-variables) section for more building and Authentication options.

## ⚡ Quickstart

> [!TIP]
> Set `IS_WEBPACK=1` and `WATCHPACK_POLLING=true` to enable hot reloading in development mode when running in Docker on Windows, as Turbopack is currently unreliable in this setup.

Using Docker

1. Set up the environment variables in the `/docsapp` directory. Refer to the [Environment Variables](#environment-variables) for more information.

2. Build the image for local development..<br>
   ```sh
   docker compose build --no-cache
   ```

3. Run the container for local development.<br>
   ```sh
   docker compose up
   ```

Open http://localhost:3000 with your browser to see the result.

> [!NOTE]
> The Fumadocs app lives inside the `/docsapp` directory.
> All files and folders referenced in the following sections are relative to the `/docsapp` directory.

In the project, you can see:

- `lib/source.ts`: Code for content source adapter, [`loader()`](https://fumadocs.dev/docs/headless/source-api) provides the interface to access your content.
- `lib/layout.shared.tsx`: Shared options for layouts, optional but preferred to keep.

| Route                     | Description                                            |
| ------------------------- | ------------------------------------------------------ |
| `app/(home)`              | The route group for your landing page and other pages. |
| `app/docs`                | The documentation layout and pages.                    |
| `app/api/search/route.ts` | The Route Handler for search.                          |

### Fumadocs MDX

A `source.config.ts` config file has been included, you can customise different options like frontmatter schema.

## Environment Variables

> [!WARNING]
> Ensure only one of `IS_BUILD_STATIC` or `IS_BUILD_DOCKER` has a value of `1` to avoid build conflicts.

Create a `.env.local` file from the `.env.example` file.

| Variable | Description |
| --- | --- |
| GOOGLE_CLIENT_ID | Google OAuth2 client ID linked with your Google Cloud Platform project. |
| GOOGLE_CLIENT_SECRET | Google OAuth2 client secret associated with the `GOOGLE_CLIENT_ID` |
| BETTER_AUTH_SECRET | Your nextauth secret (any random string will do) |
| BETTER_AUTH_URL | Your root domain URL, beginning with `http://` or `https://` protocol. |
| ALLOWED_EMAIL_DOMAINS | Allowed Google email domains to sign-in with Google eg., `gmail.com`, `company.com`.<br><quote>Leave it blank or unset if you want to allow sign-in from all **Gmail domains**.</quote> |
| ALLOWED_EMAILS | Hard-coded list of comma-separated emails allowed to sign-in with Google.<br><quote>Leave it blank or unset if you want to allow sign-in from all **Google accounts**.</quote> |
| IS_BUILD_DOCKER | If value is `1`, builds the NextJS app for Docker in production using the standalone mode build into the `/docsapp/.next/standalone` and `/docsapp/.next/static` directories. |
| IS_BUILD_STATIC | If value is `1`, builds and exports the NextJS app into a static build in the `/docsapp/out` directory when running `"npm run build"`<br><br>⚠️ Fumadocs (or any Next.js) app that uses heavy React Server Components (RSC) and Next.js server features will fail to build as a static output. Te enable true static export, [adjust necessary settings](https://nextjs.org/docs/app/guides/static-exports) in the `next.config.mjs` file and the overall app before export. |
| IS_WEBPACK | Set to `1` to run the app in development mode using **Webpack**. <br><br>⭐ **IMPORTANT**: When running the app via **Docker** on Windows OS (`docker compose up`), this must be set to `1` to enable hot reload.|
| WATCHPACK_POLLING | Set to `true` to enable Webpack-based hot reloading when running the app in Docker on Windows. Required because Turbopack hot reload is currently unreliable in this setup (Docker + Windows). |
| APP_NAME | Name of your Fumadocs documentation app. Defaults to `"Fumadocs Template"` |
| APP_SHORT_NAME | Shortname for this documentation app. Defaults to `"Fumadocs"` |
| APP_DESCRIPTION | Documentation website short description. Defaults to `"Documentation website demo"` |
| GH_USERNAME | Your GitHub username |
| GH_REPOSITORY | GitHub repository containing this documentation app |
| GH_REPO_DEFAULT_BRANCH | Default branch of the `GH_REPOSITORY`. Defaults to `"main"` |
