Desenvolvimento Backend
Desenvolvimento no lado do servidor com Node.js, NestJS, Spring Boot, Python, sockets, Nginx e integração de pagamentos.
Module 1: RESTful API Fundamentals
REST (Representational State Transfer) is the dominant architectural style for web APIs. This module covers concepts you need before building backends with any framework.
Ler artigo →RESTful API Best Practices
Practical guidelines for designing and implementing production-quality REST APIs.
Ler artigo →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.
Ler artigo →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.
Ler artigo →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.
Ler artigo →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.
Ler artigo →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.
Ler artigo →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
