Below Sample Projects demonstrate various capabilities of Specmatic in the context of a fairly realistic microservices application.

Sample Application Architecture

The sample projects consist of 3 components:

• A Frontend application.
• BFF (Backend For Frontend), the API invoked by the Frontend.
• Backend Service, the API invoked by the BFF layer.

Below sections showcase these components implemented in various languages, frameworks and communication protocols.
