This tutorial transitions a FastAPI application from SQLite to PostgreSQL for production readiness, implementing Alembic for database migrations to enable safe, version-controlled schema changes without data loss.

Corey Schafer

This tutorial demonstrates implementing a secure password reset flow in FastAPI using cryptographically secure hashed tokens stored in a database, asynchronous email sending via aiostmplib to prevent blocking, and Jinja2 templates for HTML emails, following security best practices like one-hour expiration and single-use validation.

Corey Schafer

This tutorial demonstrates how to implement offset-based pagination in FastAPI using skip and limit query parameters, covering backend schema design with SQLAlchemy queries and frontend integration with a 'load more' button pattern.

This tutorial demonstrates how to implement proper authorization in FastAPI by creating a reusable dependency that validates JWT tokens and retrieves the current user, enabling secure route protection and ownership verification while eliminating hard-coded user IDs.

Corey Schafer

This tutorial establishes backend authentication infrastructure for FastAPI by implementing Argon2 password hashing, JWT token management, and Pydantic Settings configuration, while updating database models and schemas to support secure user registration and login workflows.

Corey Schafer

This tutorial demonstrates how to connect JavaScript frontend forms to a FastAPI backend using the fetch API, implementing full CRUD functionality through Bootstrap modals while temporarily hardcoding user authentication and centralizing business logic like data sorting in SQLAlchemy queries.

Corey Schafer

This tutorial demonstrates how to refactor a monolithic FastAPI application by using APIRouter to organize routes into separate modules, keeping main.py clean while maintaining identical external URLs and functionality.
