Swagger (OpenAPI) Overview

Swagger (now known as OpenAPI) is a framework for documenting and defining RESTful APIs. It helps developers design, build, document, and consume APIs efficiently.

🔹 Key Features of Swagger (OpenAPI):

  • API Documentation: Automatically generates interactive API documentation.
  • Standardized Format: Uses JSON or YAML to define API endpoints, request/response models, and authentication.
  • Testing & Validation: Provides a UI (Swagger UI) to test APIs directly from the browser.
  • Code Generation: Can generate client SDKs and server stubs in multiple languages.
  • Version Control: Supports maintaining different API versions with clear documentation.

🛠️ How It Works:

  1. Define API endpoints using OpenAPI Specification (OAS) in swagger.json or swagger.yaml.
  2. Use tools like Swagger UI or Redoc to visualize and interact with APIs.
  3. Integrate Swagger with frameworks like Express (Node.js), FastAPI (Python), Spring Boot (Java), etc.

📌 Use Cases:

  • API Documentation for Developers
  • Testing APIs without Postman or cURL
  • Generating Client SDKs (e.g., JavaScript, Python, Java, etc.)
  • Ensuring API Contracts are Met
