Development Environment Setup

Follow these steps to set up the development environment on your local machine.

Prerequisites

  • Python 3.9+ - Core programming language
  • PostgreSQL 15+ - Database (via Docker or native installation)
  • Git - Version control
  • Docker (optional) - For containerized PostgreSQL

Installation Steps

1. Clone the Repository

git clone https://github.com/pienczyn/nordabiz.git
cd nordabiz

2. Create Virtual Environment

# Create virtual environment
python3 -m venv venv

# Activate virtual environment
# On macOS/Linux:
source venv/bin/activate

# On Windows:
venv\Scripts\activate

3. Install Python Dependencies

pip install -r requirements.txt

This will install all required packages including:

  • Flask 3.0.0 (web framework)
  • SQLAlchemy 2.0.23 (ORM)
  • psycopg2-binary 2.9.9 (PostgreSQL adapter)
  • google-generativeai 0.3.2 (Gemini AI)
  • Flask-Login, Flask-WTF, Flask-Limiter (security)
  • And more (see requirements.txt for complete list)

4. Set Up PostgreSQL Database

Option A: Using Docker (Recommended for Development)

# Start PostgreSQL container
docker compose up -d

# Verify container is running
docker ps | grep nordabiz-postgres

This creates a PostgreSQL 15 database on localhost:5433 with:

  • Database: nordabiz
  • User: nordabiz_app
  • Password: dev_password

Option B: Native PostgreSQL Installation

# Install PostgreSQL (example for Ubuntu/Debian)
sudo apt install postgresql-15 postgresql-contrib-15

# Create database and user
sudo -u postgres psql

CREATE DATABASE nordabiz;
CREATE USER nordabiz_app WITH PASSWORD 'your_password_here';
GRANT ALL PRIVILEGES ON DATABASE nordabiz TO nordabiz_app;
\q

5. Initialize Database Schema

# Apply schema (Docker setup)
docker exec -i nordabiz-postgres psql -U nordabiz_app -d nordabiz < database/schema.sql

# Or for native PostgreSQL
psql -U nordabiz_app -d nordabiz -h localhost < database/schema.sql

6. Configure Environment Variables

Create .env file in the project root:

cp .env.example .env

Edit .env and configure the following variables:

# Flask Configuration
SECRET_KEY=your-super-secret-key-change-this
FLASK_ENV=development

# Server Configuration
PORT=5000
HOST=0.0.0.0

# Database Configuration (for Docker setup)
DATABASE_URL=postgresql://nordabiz_app:dev_password@localhost:5433/nordabiz

# Google Gemini API (required for AI chat)
GOOGLE_GEMINI_API_KEY=your_gemini_api_key_here

# Google PageSpeed Insights API (optional, for SEO audits)
GOOGLE_PAGESPEED_API_KEY=your_pagespeed_api_key_here

# Google Places API (optional, for GBP audits)
GOOGLE_PLACES_API_KEY=your_places_api_key_here

# Email Configuration (optional, for user verification)
MAIL_SERVER=smtp.gmail.com
MAIL_PORT=587
MAIL_USE_TLS=True
MAIL_USERNAME=your_email@gmail.com
MAIL_PASSWORD=your_app_password_here
MAIL_DEFAULT_SENDER=noreply@norda-biznes.info

# Application URLs
APP_URL=http://localhost:5000
VERIFY_EMAIL_URL=http://localhost:5000/verify-email

Getting API Keys:

7. Run the Application

# Ensure virtual environment is activated
source venv/bin/activate  # or venv\Scripts\activate on Windows

# Run Flask development server
python3 app.py

The application will start on http://localhost:5000

Default ports:

  • Flask app: 5000 (or 5001 if 5000 is occupied)
  • PostgreSQL (Docker): 5433 (mapped from container's 5432)

8. Verify Installation

Open your browser and navigate to:

Development Workflow

# Start PostgreSQL (if using Docker)
docker compose up -d

# Activate virtual environment
source venv/bin/activate

# Run application
python3 app.py

# In another terminal: Run tests
python -m pytest tests/

# Stop PostgreSQL when done
docker compose down

Troubleshooting

Database Connection Issues:

# Check PostgreSQL is running (Docker)
docker ps | grep nordabiz-postgres

# Check PostgreSQL logs
docker logs nordabiz-postgres

# Restart PostgreSQL container
docker compose restart

Port Already in Use:

# Change PORT in .env file
PORT=5001

# Or stop conflicting service
lsof -ti:5000 | xargs kill -9

Missing Dependencies:

# Reinstall all dependencies
pip install -r requirements.txt --force-reinstall

Database Schema Issues:

# Reset database (Docker)
docker compose down -v  # WARNING: Deletes all data!
docker compose up -d
docker exec -i nordabiz-postgres psql -U nordabiz_app -d nordabiz < database/schema.sql

For more detailed database setup and management, see database/README.md.
