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

# 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)
