zhttp.http

Represents an immutable collection of headers i.e. essentially a Chunk[(String, String)]. It extends HeaderExtensions and has a ton of powerful operators that can be used to add, remove and modify headers.

NOTE: Generic operators that are not specific to Headers should not be defined here. A better place would be one of the traits extended by HeaderExtension.

A functional domain to model Http apps using ZIO and that can work over any kind of request and response types.

Holds HttpData that needs to be written on the HttpChannel

Middlewares are essentially transformations that one can apply on any Http to produce a new one. They can modify requests and responses and also transform them into more concrete domain entities.

You can think of middlewares as a functions —

 type Middleware[R, E, AIn, BIn, AOut, BOut] = Http[R, E, AIn, BIn] => Http[R, E, AOut, BOut]

The AIn and BIn type params represent the type params of the input Http. The AOut and BOut type params represent the type params of the output Http.

Models the set of operations that one would want to apply on a Response.

Instead of using just String as path params, using the RouteDecoderModule we can extract and converted params into a specific type also.

Http.collect[Request] {
 case GET -> !! / "user" / int(id) => Response.text("User id requested: ${id}")
 case GET -> !! / "user" / name    => Response.text("User name requested: ${name}")
}

If the request looks like GET /user/100 then it would match the first case. This is because internally the id param can be decoded into an Int. If a request of the form GET /user/zio is made, in that case the second case is matched.
