🚀 Quick Start

Prerequisites

• Node.js (v14+)
• MongoDB (running locally or via Atlas)

Local Development

1. Install dependencies:

   npm install

2. Initialize Database: Ensure MongoDB is running, then seed the database with initial data:

   npm run db:seed

3. Run the Application:

   • Development mode (with auto-reload):

     npm run dev

   • Production mode:

cd ~ mkdir skilltree && cd skilltree wget https://raw.githubusercontent.com/sicambria/skilltree/master/install/skilltree_install_debian9.sh chmod +x skilltree_install_debian9.sh nano skilltree_install_debian9.sh # Configure before running ./skilltree_install_debian9.sh

**Option 2: Docker (Beta)**

```bash
# Build images
docker build --no-cache -t localhost/skilltree-mongodb:latest ./docker-build/mongodb/
docker build --no-cache -t localhost/skilltree-nginx:latest ./docker-build/nginx/
docker build --no-cache -t localhost/skilltree-nodejs:latest ./docker-build/nodejs/

# Run containers (in order)
docker run -d -p <IP>:27017:27017 localhost/skilltree-mongodb
docker run -d -p <IP>:3000:3000 -e DBADDRESS=<IP> localhost/skilltree-nodejs
docker run -d -e BACKEND=<IP> -p 0.0.0.0:80:80 localhost/skilltree-nginx

Production Nginx Setup

After installation, configure /etc/nginx/sites-available/default:

server {
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;

    ssl_certificate     /etc/letsencrypt/live/YOUR_DOMAIN/cert.pem;
    ssl_certificate_key /etc/letsencrypt/live/YOUR_DOMAIN/privkey.pem;

    location / {
        proxy_pass http://localhost:3000/;
    }
}

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    return 301 https://$host$request_uri;
}

⚙️ Configuration

Environment Variables (.env)

For local development, a .env file is used to store environment-specific settings. This file is ignored by Git.

Default credentials for local testing:

• Username: admin
  • Password: admin

1. Domain: Register a domain (e.g., via Freenom)
2. Security: Update config.js with a long, random secret key
3. Database: Configure MongoDB connection (local or MongoDB Atlas)
