FastAPI stands out among modern Python web frameworks with auto-generated docs based on type hints, async support, and Node.js-level performance. This hands-on guide builds a complete CRUD API from scratch covering route definition, request validation, dependency injection, and database integration—master FastAPI essentials in 30 minutes.
Comprehensive Alembic (official SQLAlchemy migration tool) guide: env.py setup, autogenerate detecting model changes (fields, indexes, constraints), batch scripts, downgrade rollback strategies, plus standard SOP for multi-developer migration branch conflicts and divergent head merging, with production deploy checklist.
End the API style debate: compared across 7 dimensions - network efficiency, DX, evolution cost, caching, type-safety, security risks, ecosystem - with clear decision tree and hybrid architecture patterns.
Advanced patterns: CQRS separate read/write models for query performance; Event Sourcing using events as source of truth for audit + time travel. Covers consistency, snapshots, idempotency pitfalls and anti-patterns.
