What is API & REST Framework
MindCraft Backend Web Dev - Backend Basics
Course by: MindCraft
In this detailed lecture, we explore the concept of APIs and the REST framework, which are crucial for modern cloud applications and web services. Whether you're new to backend development or seeking to deepen your understanding, this session provides a comprehensive overview of APIs and REST APIs, highlighting their significance and benefits.
We start by defining what an API (Application Programming Interface) is and how it serves as an intermediary that allows different software applications to communicate with each other. We then focus on REST (Representational State Transfer) APIs, a popular architectural style for designing networked applications. You'll learn about the principles behind REST, such as stateless communication and resource-based interactions, and how these principles make REST APIs a powerful tool for developing scalable and efficient web services.
Nathan Hekman from IBM Cloud provides an insightful visual explanation of how REST APIs function and their advantages for companies. The lecture covers the benefits of using REST APIs, including their simplicity, scalability, and flexibility. You'll see real-world examples and understand how REST APIs can streamline communication between services, enhance application performance, and support cloud-based solutions.
By the end of this lecture, you'll have a thorough understanding of APIs and REST frameworks, and you'll be able to appreciate their role in creating robust and scalable cloud applications.
