Symmetry

• Connecting different applications together

Http handlers in http4ts are symmetric. Symmetric means that the http client follows the same type definition as the http server does. In other words, an http client (just like an http server) is a function that accepts an HttpRequest and returns an HttpResponse:

type HttpHandler = (req: HttpRequest) => HttpResponse | Promise<HttpResponse>;

Providing symmetric interfaces for client and server improves the learning curve and helps onboarding new developers to your application's codebase.

Another benefit of this model is that you can easily mock the http clients in your application by replacing the implementation of them with a mocked http handler.

You can also use another http4ts server application as the client of an http4ts application without putting them on the network. This is possible because the http client and server are interchangeable.

Yet another benefit is that you can reuse your filters on both server handlers and http clients.
