Creando APIs en 5 Minutos con FastAPI

Construyendo redes: Comunidades y Academia
En esta charla, exploraremos cómo FastAPI ha revolucionado el desarrollo de APIs, permitiendo crear aplicaciones web rápidas, eficientes y altamente escalables en cuestión de minutos. FastAPI es un framework moderno para Python que destaca por su simplicidad, alto rendimiento y la capacidad de generar automáticamente documentación interactiva. Durante la sesión, aprenderás a configurar tu entorno y crear una API básica desde cero. Además, veremos cómo FastAPI, gracias a su compatibilidad con el estándar OpenAPI, facilita la integración y el testing de APIs.

🎯 Key points for quick navigation:
00:00:05 *🎤 Introduction to the API Session*
- The session focuses on creating APIs in five minutes using FastAPI,
- Exploration of the framework's revolutionary impact on API development,
- Introduction of the speaker Miguel Amaya and his background.
00:02:24 *📚 Understanding APIs and REST*
- Explaining API (Application Programming Interface) and REST (Representational State Transfer) concepts,
- Characteristics of RESTful APIs including HTTP verbs and stateless interactions,
- API operation analogy comparing backend processes to a restaurant kitchen.
00:06:14 *🌐 API Architecture and HTTP Verbs*
- Explanation of HTTP verbs: GET, POST, PUT, DELETE,
- Importance of endpoints and the independent nature of API-client interactions,
- Segregation of front-end and back-end development, advantages in scalability and device interoperability.
00:13:09 *📊 API Status Codes and Error Handling*
- Overview of status codes like 200, 201, 400, 401, 403, 404, 500, 503,
- Significance in indicating request results and debugging,
- Error indication and responsibility division between developers and server.
00:19:03 *🚀 FastAPI Framework Introduction*
- Key features of FastAPI and its benefits for quick API development,
- Based on Python's type annotations for enhanced simplicity and speed,
- Adoption by major companies for various applications, highlighting its efficiency and reliability.
21:25 *🚀 FastAPI and Python Typing*
- FastAPI's performance is competitive with other frameworks despite its relative newness.
- Python is strongly typed but dynamically typed, and FastAPI utilizes static typing for precise API requests and responses.
- FastAPI automatically validates data and generates interactive documentation using standards like OpenAPI.
23:58 *🐍 Setting Up Python Environment*
- Python 3 is required, and its installation differs across operating systems.
- PyCharm IDE offers virtual environments to manage different Python package dependencies for different projects.
- Virtual environments prevent package incompatibility issues by providing isolated setups.
28:15 *📦 FastAPI Installation*
- Install FastAPI using the package manager pip.
- FastAPI depends on components like Starlette for web server capabilities.
- FastAPI supports asynchronous programming, but this session focuses on basic concepts.
30:03 *📘 Introduction to Typing and Pydantic*
- Type hints improve Python's documentation and aid in code completion.
- Pydantic is used for data validation and modeling using Python's static typing.
- Demonstrating type enforcement in Pydantic models helps validate input data.
38:43 *🌐 Creating a Simple FastAPI Application*
- A FastAPI application begins by importing FastAPI and creating an app instance.
- Running a local server provides an endpoint returning a simple "Hello World".
- FastAPI auto-generates interactive API documentation using Swagger UI.
01:05:56 *🔐 Security Features*
- JWT and Bearer tokens are useful for authentication and authorization,
- Authentication verifies identity, while authorization checks resource access permissions,
- FastAPI ensures unauthorized resources remain inaccessible.
01:06:51 *☁️ Cloud Deployment*
- AWS is recommended for deploying FastAPI applications in a commercial environment,
- Linux servers are used for hosting containers and APIs,
- FastAPI is compatible with various cloud platforms.
01:07:49 *📚 Community and Education*
- Gratitude expressed to participants and organizers of the session,
- Announcement of an upcoming free ebook by Diego Saavedra on FastAPI,
- The ebook will contain expanded concepts and practical examples.
