README

# Blank Files Website

Laravel application that powers [blankfiles.com](https://blankfiles.com). Browse and download minimal valid blank files by type and category. File data and assets are served from the [filearchitect/blank-files](https://github.com/filearchitect/blank-files) repository via a configurable CDN.

## Requirements

- PHP 8.2+
- Composer
- Node.js 18+ (for Vite frontend build)

## Installation

```bash
git clone https://github.com/filearchitect/blankfiles-website.git
cd blankfiles-website
composer install
cp .env.example .env
php artisan key:generate
```

Set `CDN_URL` in `.env` (see [Configuration](#configuration)). Then build the frontend and run the app:

```bash
npm install && npm run build
php artisan serve
```

Or use [Laravel Herd](https://herd.laravel.com) with a `.test` domain.

## Configuration

| Variable        | Description                                                                                                                                                                                                                                                                                                                                                                                                                      |
| --------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `CDN_URL`       | **Required.** Base URL used to construct downloadable file URLs as `{CDN_URL}/files/{filename}`. Default: `https://raw.githubusercontent.com/filearchitect/blank-files/main` (set in [config/app.php](config/app.php)). |
| `CATALOG_URL`   | Optional. Direct URL for the catalog JSON (`files/files.json`). Default is `https://raw.githubusercontent.com/filearchitect/blank-files/main/files/files.json` for freshness. |
| `CACHE_ENABLED` | Optional. When `true`, the file list from the CDN is cached. TTL is controlled by `CATALOG_TTL_MINUTES` (default `10`). See [config/cache.php](config/cache.php) and [app/Services/FileService.php](app/Services/FileService.php).                                                                                                                                                                                           |
| `CATALOG_TTL_MINUTES` | Optional. Cache TTL in minutes for the remote catalog when `CACHE_ENABLED=true`. Lower values reflect new formats sooner; higher values reduce CDN fetches. |
| `API_KEYS` | Optional. Comma-separated API keys for higher-rate API clients (used by `X-API-Key` or `Authorization: Bearer ...`). |
| `API_PUBLIC_RATE_LIMIT` | Optional. Public API requests/minute limit (default `30`). |
| `API_KEY_RATE_LIMIT` | Optional. API-key requests/minute limit (default `300`). |
| `API_USAGE_LOG_CHANNEL` | Optional. Logging channel for API usage analytics (default `api_usage`). |
| `OPENPANEL_CLIENT_ID` | Optional. Enables OpenPanel web analytics script when set. |
| `OPENPANEL_CLIENT_SECRET` | Optional. Reserved for server-side OpenPanel events (not exposed to browser script). |

| `app/Services/FileService.php`                | Fetches catalog JSON (`CATALOG_URL`) and formats file URLs from `CDN_URL`. |
| `routes/web.php`                              | Web routes (home, files show, download).                     |
| `routes/api.php`                              | API v1 routes.                                               |
| `resources/views/files/`                      | Blade views for file listing and file detail.                |

## Deployment

On push to `main`, GitHub Actions:

1. Builds the frontend (Vite) with `npm ci` and `npm run build`.
2. SCPs `public/build/` to the Forge server.
3. Triggers a Laravel Forge deployment.
4. Runs `php artisan optimize:clear` on the server.

Required repository secrets:

- `FORGE_SSH_HOST` — SSH host for the server.
- `FORGE_SSH_USER` — SSH user (e.g. `forge`).
- `SSH_PRIVATE_KEY` — Private key for SCP/SSH.
- `FORGE_SERVER_ID` — Forge server ID.
- `FORGE_SITE_ID` — Forge site ID.
- `FORGE_API_KEY` — Forge deploy token.

See [.github/workflows/deploy.yml](.github/workflows/deploy.yml).

| `GET`  | `/`                                 | Homepage: file list by category. Responds with JSON when `Accept: application/json`. Throttle: 30/min.                                     |
| `GET`  | `/upload-testing`                   | Binary-focused landing page for upload testing intent, linking to high-demand file formats and categories.                                   |
| `GET`  | `/files/{category}/{type}`          | SEO-friendly file detail page (e.g. `/files/document-spreadsheet/xlsx`). Constraints: `category`, `type` = `[A-Za-z0-9\-]+`.               |
| `GET`  | `/files/download/{category}/{type}` | Download proxy: streams the file with `Content-Disposition: attachment` (filename `blank.{type}` or `blank.{type}.zip`). Throttle: 60/min. |

### API routes (prefix `api/v1`)

| Method | Path                   | Response                                                                                                                                                        |
| ------ | ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `GET`  | `/api/v1/files`        | `{ "files": [ ... ], "meta": { "version", "generated_at", "count" } }`.                                                                                         |
| `GET`  | `/api/v1/files/{type}` | Same schema, filtered by extension.                                                                                                                              |
| `GET`  | `/api/v1/files/{category}/{type}` | Same schema with exactly one matching entry when found; `404` when missing.                                                                                   |
| `GET`  | `/api/v1/status` | API health + aggregate catalog metrics (`file_count`, `type_count`, `category_count`) and upstream source info. |

### Machine-friendly notes

- The canonical file catalog schema is defined in the [blank-files](https://github.com/filearchitect/blank-files) repo: `files/files.json` (key `files`, array of `{ type, url, category, package? }`).
- Download URLs: use the API `url` field for direct CDN access, or `GET /files/download/{category}/{type}` for a same-origin download with a predictable filename.
- Conditional requests are supported on API responses and sitemap (`ETag`, `Last-Modified`).
- Rate limits: public IP-based limits and optional API-key limits (`X-API-Key`).
- API usage analytics are logged to `storage/logs/api-usage-*.log` (configurable channel).
- Compatibility policy: [API policy](https://blankfiles.com/api-policy).
- Web landing analytics for growth pages are logged to `storage/logs/web-traffic-*.log`.

### Client snippets

```bash
curl -sS "https://blankfiles.com/api/v1/files/document-spreadsheet/xlsx" \
  -H "Accept: application/json" \
  -H "X-API-Key: $BLANKFILES_API_KEY"
```

```js
const res = await fetch("https://blankfiles.com/api/v1/files", {
  headers: { "Accept": "application/json", "If-None-Match": etag }
});
if (res.status === 304) {
  // unchanged
}
```

```python
import requests
r = requests.get("https://blankfiles.com/api/v1/status", timeout=20)
r.raise_for_status()
print(r.json())
```

### Compatibility policy

- URL versioning is stable under `/api/v1/*`.
- Breaking changes require a new major API path version.
- Deprecated endpoints are kept for at least 90 days before removal.
- New fields may be added; clients should ignore unknown fields.

## MCP server (for agent marketplaces/registries)

This repository now includes a minimal MCP server that exposes Blank Files as tool calls.

- Script: `scripts/mcp/blankfiles-mcp.mjs`
- Run: `npm run mcp:server`
- Optional env: `BLANKFILES_BASE_URL` (default: `https://blankfiles.com`)

Available MCP tools:

- `list_blank_files` — list files, optional filters (`category`, `type`, `limit`)
- `files_by_type` — list entries by extension
- `file_by_category_type` — deterministic single lookup by category + extension

Example local MCP client config entry:

```json
{
  "mcpServers": {
    "blankfiles": {
      "command": "node",
      "args": ["/absolute/path/to/blankfiles-website/scripts/mcp/blankfiles-mcp.mjs"],
      "env": {
        "BLANKFILES_BASE_URL": "https://blankfiles.com"
      }
    }
  }
}
```
