Samples & Walkthroughs

Swagger Express Middleware comes two samples that use the Swagger Pet Store API.

Sample 1

This sample demonstrates the most simplistic usage of Swagger Express Middleware. It simply creates a new Express Application and adds all of the Swagger middleware without changing any options, and without adding any custom middleware.

Sample 2

This sample demonstrates a few more advanced features of Swagger Express Middleware, such as setting a few options, initializing the mock data store, and adding custom middleware logic.
