Contract-first REST APIs in Django

Lepo – Contract-first REST APIs in Django

Lepo is a contract-first API framework that enables you to design your API using the OpenAPI specification (formerly known as Swagger) and implement it in Python 3 and Django.

What does it mean when we say contract-first? Contrast this to code-first:

• Code-first: First write the implementation of your API endpoints. Interactive API documentation is generated from docstrings and other meta-data embedded in the implementation. The Django REST Framework is a popular example of a framework that promotes code-first style.
• Contract-first (or API first): Write the contract of your API first in machine-readable documentation describing the available endpoints and their input and output. API calls are mapped into view functions using meta-data embedded in this machine-readable documentation. Other examples of contract-first frameworks include connexion (using Flask) and Apigee 127 (using Node.js and Express).

Features

• Automatic routing of requests to endpoints
• Body and query parameter validation
• Output validation (soon!)
• Embedded Swagger UI
