CI	Release

Welcome to Typed Schema

Typed schema is an http service definition DSL, currently translating to akka-http Routes and OpenApi 3.0 definition inspired by the haskell-servant library.

Getting started

Typed Schema is published to Maven Central and cross-built for Scala 2.12 and 2.13 so you can just add the following to your build:

libraryDependencies ++= List(
  "ru.tinkoff" %% "typed-schema-swagger" % "latest version in badge",
  "ru.tinkoff" %% "typed-schema-finagle-zio" % "latest version in badge",
  "ru.tinkoff" %% "typed-schema-finagle-custom" % "latest version in badge",
)

or

libraryDependencies ++= List(
  "ru.tinkoff" %% "typed-schema-swagger"        % "latest version in badge",
  "ru.tinkoff" %% "typed-schema-finagle-env"    % "latest version in badge",
  "ru.tinkoff" %% "typed-schema-finagle-custom" % "latest version in badge",
)

or

libraryDependencies ++= List(
  "ru.tinkoff" %% "typed-schema-swagger"   % "latest version in badge",
  "ru.tinkoff" %% "typed-schema-akka-http" % "latest version in badge",
)

Motivation

We the People building services using modern scala often struggling to satisfy following requirements

• Service implementation should be checked to be compatible with OpenApi 3.0 specifications at the compile time
• Service definition should be detachable from the implementation and exportable as mere specification
• There should be an easy way to migrate all the services to different effect\future\task implementation without changing any definition
• There should be some way to migrate all the service to another framework without reimplementing them
