REST, RESTful APIs, and API documentation A dive-in on the most used architectural style to communicate between modern web applications!

REST (Representational State Transfer) is an architectural style used for designing network-based applications, particularly web APIs. It provides a set of constraints that improve the scalability, performance, and manageability of software systems. RESTful APIs use standard HTTP methods for CRUD operations and ensure stateless communication, promoting separation of concerns. Key constraints include client-server architecture, uniform interface, statelessness, cacheability, layered system, and optional code-on-demand. Clear and consistent documentation is crucial, and tools like OpenApi and Swagger can help in documenting APIs effectively.
