Quick Start

# Clone
git clone https://git.theta42.com/nova/openclaw-webui.git
cd openclaw-webui

# Install
npm install

# Development (hot reload)
npm run dev

# Production build
npm run build

# Production server
NODE_ENV=production npm start

Configuration

Uses JSON config files in conf/ directory:

conf/
├── base.json           # Base config (all environments)
├── development.json    # Dev overrides (auth disabled)
├── production.json     # Production overrides
├── secrets.json        # Secrets (gitignored!)
└── secrets.example.json # Template

Load Order

Files merge in order: base.json → [environment].json → secrets.json

Example Configs

conf/base.json:

{
  "server": { "port": 8089 },
  "gateway": { "url": "http://127.0.0.1:18789" },
  "auth": {
    "disabled": false,
    "ldap": {
      "enabled": true,
      "url": "ldap://10.1.0.55:389",
      "baseDN": "dc=example,dc=com",
      "searchFilter": "(uid={{username}})"
    }
  }
}

conf/secrets.json:

{
  "gateway": { "token": "your-openclaw-token" },
  "session": { "secret": "random-session-secret" },
  "auth": {
    "ldap": {
      "bindDN": "cn=service,ou=people,dc=example,dc=com",
      "bindPassword": "ldap-password"
    }
  }
}

Environment Variables

Can override config at runtime:

PORT - Server port
OPENCLAW_GATEWAY - Gateway URL
OPENCLAW_TOKEN - Gateway auth token
SESSION_SECRET - Session signing secret
LDAP_ENABLED - Enable LDAP auth

LDAP Authentication

Supports standard LDAP servers (OpenLDAP, Active Directory):

Service binds with bindDN + bindPassword
Searches for user with searchFilter
Binds as user to verify password

Search Filter: Use {{username}} as placeholder:

(&(memberof=cn=app_access,ou=groups,dc=example,dc=com)(uid={{username}}))
