Features: - Multi-source data collection (news, social media, government, tourism, business) - RESTful API with FastAPI - Automated scheduling for continuous data collection - Intelligence brief generation - Real-time trending topics tracking - Alert system for important updates - Web scraping with rate limiting and caching - Social media integration (Twitter, Instagram) - NLP-powered categorization and processing - Docker support for easy deployment - CLI for manual operations Components: - Data models with SQLAlchemy - Base collector class with extensible architecture - Source-specific collectors (news, social, government, tourism, business) - Data processor for brief generation - Scheduler for automated collection - Comprehensive API endpoints - CLI interface for manual control Documentation: - Complete README with setup instructions - Quick start guide - Example usage scripts - Docker Compose configuration - Environment configuration templates --- nairobi-info-collector/.env.example | 88 +++++ nairobi-info-collector/.gitignore | 65 ++++ nairobi-info-collector/Dockerfile | 38 ++ nairobi-info-collector/LICENSE | 21 + nairobi-info-collector/QUICKSTART.md | 236 +++++++++++ nairobi-info-collector/README.md | 213 ++++++++++ nairobi-info-collector/app/__init__.py | 7 + nairobi-info-collector/app/api/__init__.py | 6 + nairobi-info-collector/app/api/routes.py | 326 ++++++++++++++++ .../app/collectors/__init__.py | 18 + .../app/collectors/base_collector.py | 274 +++++++++++++ .../app/collectors/business_collector.py | 148 +++++++ .../app/collectors/government_collector.py | 213 ++++++++++ .../app/collectors/news_collector.py | 340 ++++++++++++++++ .../app/collectors/social_media_collector.py | 310 +++++++++++++++ .../app/collectors/tourism_collector.py | 221 +++++++++++ nairobi-info-collector/app/config.py | 250 ++++++++++++ .../app/database/__init__.py | 6 + nairobi-info-collector/app/database/db.py | 72 ++++ nairobi-info-collector/app/main.py | 119 ++++++ nairobi-info-collector/app/models/__init__.py | 20 + .../app/models/data_models.py | 306 +++++++++++++++ .../app/processors/__init__.py | 6 + .../app/processors/data_processor.py | 365 ++++++++++++++++++ .../app/scheduler/__init__.py | 6 + nairobi-info-collector/app/scheduler/tasks.py | 150 +++++++ nairobi-info-collector/cli.py | 187 +++++++++ nairobi-info-collector/docker-compose.yml | 72 ++++ nairobi-info-collector/example_usage.py | 237 ++++++++++++ nairobi-info-collector/requirements.txt | 79 ++++ nairobi-info-collector/setup.sh | 109 ++++++ 31 files changed, 4508 insertions(+) create mode 100644 nairobi-info-collector/.env.example create mode 100644 nairobi-info-collector/.gitignore create mode 100644 nairobi-info-collector/Dockerfile create mode 100644 nairobi-info-collector/LICENSE create mode 100644 nairobi-info-collector/QUICKSTART.md create mode 100644 nairobi-info-collector/README.md create mode 100644 nairobi-info-collector/app/__init__.py create mode 100644 nairobi-info-collector/app/api/__init__.py create mode 100644 nairobi-info-collector/app/api/routes.py create mode 100644 nairobi-info-collector/app/collectors/__init__.py create mode 100644 nairobi-info-collector/app/collectors/base_collector.py create mode 100644 nairobi-info-collector/app/collectors/business_collector.py create mode 100644 nairobi-info-collector/app/collectors/government_collector.py create mode 100644 nairobi-info-collector/app/collectors/news_collector.py create mode 100644 nairobi-info-collector/app/collectors/social_media_collector.py create mode 100644 nairobi-info-collector/app/collectors/tourism_collector.py create mode 100644 nairobi-info-collector/app/config.py create mode 100644 nairobi-info-collector/app/database/__init__.py create mode 100644 nairobi-info-collector/app/database/db.py create mode 100644 nairobi-info-collector/app/main.py create mode 100644 nairobi-info-collector/app/models/__init__.py create mode 100644 nairobi-info-collector/app/models/data_models.py create mode 100644 nairobi-info-collector/app/processors/__init__.py create mode 100644 nairobi-info-collector/app/processors/data_processor.py create mode 100644 nairobi-info-collector/app/scheduler/__init__.py create mode 100644 nairobi-info-collector/app/scheduler/tasks.py create mode 100755 nairobi-info-collector/cli.py create mode 100644 nairobi-info-collector/docker-compose.yml create mode 100755 nairobi-info-collector/example_usage.py create mode 100644 nairobi-info-collector/requirements.txt create mode 100755 nairobi-info-collector/setup.sh diff --git a/nairobi-info-collector/.env.example b/nairobi-info-collector/.env.example new file mode 100644 index 0000000..c53b827 --- /dev/null +++ b/nairobi-info-collector/.env.example @@ -0,0 +1,88 @@ +# Application Settings +APP_NAME="Nairobi Information Collector" +APP_VERSION="1.0.0" +DEBUG=True +ENVIRONMENT=development + +# Server Configuration +HOST=0.0.0.0 +PORT=8000 + +# Database Configuration +DATABASE_URL=postgresql://nairobiuser:password@localhost:5432/nairobi_info +# For SQLite (development): sqlite:///./nairobi_info.db + +# Redis Configuration +REDIS_URL=redis://localhost:6379/0 +REDIS_PASSWORD= + +# API Keys -
