Markdown Editor With Chat

# Markdown Editor with Chat

A lightweight, self-contained markdown editor that serves files from a local directory with optional OpenClaw gateway chat integration.

Features

• Filesystem-based: Point to any directory containing markdown files
• No database: Files are the source of truth
• Folder navigation: Browse nested directories
• Live preview: See rendered markdown as you type
• Optional chat: Connect to OpenClaw gateway for AI assistance
• Zero external dependencies: Pure Node.js, self-contained HTML

Quick Start

```bash # Start with CLI arguments (recommended) node scripts/server.mjs --folder /path/to/markdown --port 3333

# Or short form node scripts/server.mjs -f /path/to/markdown -p 3333

# With gateway chat enabled (via env vars) export OPENCLAW_GATEWAY_URL=http://127.0.0.1:18789 export OPENCLAW_GATEWAY_TOKEN=your-token node scripts/server.mjs -f /path/to/markdown ```

Then open http://localhost:3333 in your browser.

CLI Arguments

| Argument | Short | Required | Default | Description | |----------|-------|----------|---------|-------------| | `--folder` | `-f` | Yes* | - | Directory containing markdown files | | `--port` | `-p` | No | 3333 | Server port | | `--host` | `-h` | No | 127.0.0.1 | Server host (localhost only by default) | | `--help` | | No | | Show help message |

*Required unless `MARKDOWN_DIR` env var is set.

Environment Variables (fallback)

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | `MARKDOWN_DIR` | Yes* | - | Directory containing markdown files | | `PORT` | No | 3333 | Server port | | `HOST` | No | 127.0.0.1 | Server host | | `OPENCLAW_GATEWAY_URL` | No | - | Gateway URL for chat feature | | `OPENCLAW_GATEWAY_TOKEN` | No | - | Gateway auth token |

CLI arguments take precedence over environment variables.

Security

• Localhost only by default: Server binds to 127.0.0.1, rejects public IPs
• Same-origin only: No CORS headers, browser enforces same-origin policy
• Path traversal protection: Cannot access files outside MARKDOWN_DIR
• No credentials in code: All secrets via environment variables
• Gateway proxy: Tokens never exposed to browser

This is a local development tool. The API is intentionally simple (no auth) because it's designed for localhost use on directories you control.

API Endpoints

• `GET /` - Serves the editor UI
• `GET /api/files` - List files and folders
• `GET /api/files/:path` - Get file content
• `PUT /api/files/:path` - Save file content
• `POST /api/files/:path` - Create new file
• `POST /api/chat` - Proxy chat to gateway (if configured)
