The tutorial covers core fundamentals including project setup with virtual environments, creating routes with decorators, implementing CRUD operations, using Pydantic for data validation and schemas, automatic Swagger documentation, middleware implementation, CORS configuration, and deployment to Render. The example builds an issue tracker API with JSON file storage, demonstrating routing, path parameters, request/response models, enums for validation, custom middleware for timing, and production deployment. ## Full article daily.dev links to this article rather than hosting it.
