Practical guidelines for designing and implementing production-quality REST APIs.
Leer artículo →Module 2: Python FastAPI
FastAPI is a modern, high-performance Python web framework for building APIs. It uses type hints and Pydantic for validation and automatically generates OpenAPI (Swagger) documentation.
Leer artículo →Module 3: Python Flask
Flask is a lightweight micro-framework for Python. You can build REST APIs, server-rendered web apps with templates (Jinja2), or both.
Leer artículo →Module 4: Node.js Backend Development
Node.js lets you build backend services in JavaScript (or TypeScript) using the same language as the browser. Express is the most common web framework for REST APIs.
Leer artículo →Module 5: Nest.js Backend Development
Nest.js is a TypeScript-first backend framework built on Node.js. It uses modules, dependency injection, and decorators similar to Angular, and is well-suited for scalable REST APIs and microservices.
Leer artículo →Module 6: SQL Databases for Backend
Relational databases (SQL) store data in tables with rows and columns, linked by relationships and foreign keys. They are the default choice for structured, transactional data in backend applications.
Leer artículo →Module 7: NoSQL Databases for Backend
NoSQL databases use storage models other than traditional relational tables. Common types: document (e.g. MongoDB), key-value (e.g. Redis), wide-column (e.g. Cassandra), graph (e.g. Neo4j). This module focuses on documen
