Deploy and Host Wiki.js on Railway

Wiki.js is a modern, lightweight, and powerful wiki engine built on Node.js. It provides a beautiful markdown-based documentation platform with integrated user authentication, search functionality, and Git synchronization—perfect for technical documentation, knowledge bases, and internal wikis without database complexity.

About Hosting Wiki.js

Hosting Wiki.js on Railway means running a fully-featured wiki engine on a managed infrastructure platform. Railway handles server management, database provisioning, and deployment automation so you can focus on your documentation. Wiki.js uses PostgreSQL for data storage and supports real-time collaboration, version history, and permission-based access control. The deployment is containerized, scalable, and includes automatic SSL certificates. You get a modern editor interface (markdown + visual), built-in search, and multi-user support with role-based access—all running on Railway's infrastructure with minimal configuration overhead.

Common Use Cases

• Internal technical documentation for development teams with role-based access control
• Knowledge base and troubleshooting guides with version history and Git integration
• API documentation with markdown support and search functionality
• Project wikis with multi-user editing and permission management
• Compliance and process documentation with audit trails and user authentication

• PostgreSQL Database (included with Railway template)
• Node.js 12+ (handled by Railway container)
• Git (optional, for Git sync features)
• Docker (Railway handles containerization automatically)

Implementation Details

Railway Template Quick Start:

# Visit Railway and use the Wiki.js template
https://railway.app/template/wikijs

# After deployment, Railway automatically:
# 1. Creates PostgreSQL database
# 2. Deploys Wiki.js container
# 3. Generates admin URL
# 4. Configures environment variables

First Time Setup (in Wiki.js UI):

// After deployment, access admin panel and configure:
1. Admin user creation (username/password)
2. Site title and tagline
3. Logo and branding
4. User authentication method
5. Email notifications (optional)
6. Upload storage (local or cloud)

Environment Variables (Railway sets these automatically):

DB_TYPE=postgres
DB_HOST=
DB_PORT=5432
DB_USER=
DB_PASSWORD=
DB_NAME=wiki
LOGURU_LEVEL=info

Adding Users Programmatically:

// POST /api/users/create (requires admin token)
{
  "email": "user@example.com",
  "password": "secure-password",
  "name": "User Name",
  "roleId": 3  // 3 = Editor, 2 = Contributor, 4 = Guest
}

Git Sync Configuration (Optional):

# In Wiki.js Settings > Storage > Git
- Repository URL: https://github.com/yourorg/wiki-repo.git
- Branch: main
- Path: /
- Pull interval: 0 (disable auto-pull) or set in minutes
- Commit message: Updated via Wiki.js
