Complete documentation of the Facebook Writer migration from Streamlit to FastAPI, including architectural changes, feature enhancements, and content type expansions.

Migration Overview

The Facebook Writer has been successfully migrated from a Streamlit-based application to a robust FastAPI service, expanding its capabilities with enhanced content types, improved performance, and comprehensive API integration.

Migration Background

Before Migration

Original Implementation: - Framework: Streamlit web application - Location: ToBeMigrated/ai_writers/facebook_writer/ - Architecture: Monolithic application with embedded UI logic - Features: Basic text-based content generation for Facebook posts - Integration: Standalone application with limited API access

After Migration

New Implementation: - Framework: FastAPI microservice - Location: Integrated into main ALwrity backend (backend/) - Architecture: Modular API service with clean separation of concerns - Features: Comprehensive Facebook content ecosystem with multimedia support - Integration: Fully integrated with ALwrity ecosystem
