Tie allows generation of Haskell server stubs from OpenAPI (v 3.x) specifications.

If you are looking for a generator for Haskell client code, check out the Haskell-OpenAPI-Client-Code-Generator project.

$ tie --help
tie - openapi3 server code generator

Usage: tie [-o|--output DIR] [--module-name MODULE] [--package-name PACKAGE]
           [--extra-package PACKAGE] FILE

                           (default: "OpenAPI")
  --package-name PACKAGE   Name of the generated cabal project
                           (default: "open-api")
