Overview
Servant provides a type-level domain-specific language (DSL) to describe World Wide Web application programming interfaces (Web APIs); various interpretations of such descriptions are possible: as a server, which dispatches requests to handlers; as documentation and schema specifications for the API; and as client libraries in various languages.[6]
The type-level approach by Servant solves the expression problem by allowing the extensibility along the dimensions of both data and behavior.[6] New combinators or terms in the DSL can be modularly introduced, as can new interpretations of them, as entirely separate packages. As of 2023[update], well over 100 packages related to Servant have been published in the Haskell package repository.[7]
