Fern has a first-class integration with Express. Fern automatically generates:
- Typescript interfaces for your API types
- Exceptions that you can throw for non-200 responses
- Interfaces for you to define your business logic.
All the networking/HTTP logic is auto-generated by Fern under the hood.
- Fern Definition Registry is an Express server that uses Fern under the hood.
- The Fern Express Starter is a simple example of a Fern-powered Express server.
