zio.http.api

A combiner is a type class responsible for combining invariant type parameters. It is used to compose the parameters of the zio.http.api.HttpCodec data type.

A Doc models documentation for an endpoint or input.

A zio.http.api.EndpointExecutor is responsible for taking an endpoint invocation, and executing this invocation, returning the final result, or failing with some kind of RPC error.

An zio.http.api.EndpointSpec represents an API endpoint for the HTTP protocol. Every API has an input, which comes from a combination of the HTTP path, query string parameters, and headers, and an output, which is the data computed by the handler of the API.

As zio.http.api.EndpointSpec is a purely declarative encoding of an endpoint, it is possible to use this model to generate a zio.http.App (by supplying a handler for the endpoint), to generate OpenAPI documentation, to generate a type-safe Scala client for the endpoint, and possibly, to generate client libraries in other programming languages.

Represents a collection of API endpoints that all have handlers.

A zio.http.api.HttpCodec represents a codec for a part of an HTTP request. HttpCodec the HTTP protocol, these parts may be the unconsumed portion of the HTTP path (a route codec), the query string parameters (a query codec), the request headers (a header codec), or the request body (a body codec).

A HttpCodec is a purely declarative description of an input, and therefore, it can be used to generate documentation, clients, and client libraries.

HttpCodecs are a bit like invertible multi-channel parsers.

A Middleware represents the implementation of a MiddlewareSpec, intercepting parts of the request, and appending to the response.
