Kebs\n\n##### Scala library to eliminate boilerplate\n\n[![Maven Central](https://img.shields.io/maven-central/v/pl.iterators/kebs-slick_2.13.svg)](https://central.sonatype.com/artifact/pl.iterators/kebs-core_2.13)\n[![GitHub license](https://img.shields.io/badge/license-MIT-blue.svg)](https://raw.githubusercontent.com/theiterators/kebs/master/COPYING)\n[![Build Status](https://github.com/theiterators/kebs/actions/workflows/ci.yml/badge.svg?branch=master)](https://github.com/theiterators/kebs/actions/workflows/ci.yml?query=branch%3Amaster)\n\n![logo](https://raw.githubusercontent.com/theiterators/kebs/master/logo.png)\n\nA library maintained by [Iterators](https://www.iteratorshq.com). Supports Scala 2.13 and Scala 3.\n\n### What is Kebs?\n\nKebs automatically derives typeclass instances (JSON codecs, DB column mappings, HTTP unmarshallers, etc.) for your domain types so you don't have to write them by hand.\n\n```scala\ncase class UserId(value: String) extends AnyVal\ncase class Email(value: String) extends AnyVal\n\n// Without Kebs — manual boilerplate for every type × every library:\nimplicit val userIdCol: BaseColumnType[UserId] = MappedColumnType.base(_.value, UserId.apply)\nimplicit val userIdEnc: Encoder[UserId] = Encoder[String].contramap(_.value)\n// ... repeat dozens of times\n\n// With Kebs — just mix in a trait. Everything is derived at compile time.\n```\n\n### Documentation\n\n**[https://theiterators.github.io/kebs/](https://theiterators.github.io/kebs/)**\n\n### Quick start\n\n```scala\n// build.sbt — pick the modules you need\nlibraryDependencies ++= Seq(\n  \"pl.iterators\" %% \"kebs-slick\"      % \"2.1.6\",\n  \"pl.iterators\" %% \"kebs-circe\"      % \"2.1.6\",\n  \"pl.iterators\" %% \"kebs-pekko-http\" % \"2.1.6\",\n  \"pl.iterators\" %% \"kebs-instances\"  % \"2.1.6\"\n)\n```\n\n### Available modules\n\n| Module | What you get |\n|---|---|\n| `kebs-slick` | Automatic Slick column type mappings, Postgres array \u0026 hstore support |\n| `kebs-doobie` | Doobie `Meta` / `Get` / `Put` instances |\n| `kebs-spray-json` | Spray `JsonFormat` derivation (flat, snakified, \u003e22 fields) |\n| `kebs-play-json` | Play JSON `Format` instances |\n| `kebs-circe` | Circe `Encoder` / `Decoder` derivation (snakified/capitalized) |\n| `kebs-akka-http` | Akka HTTP unmarshallers + path matchers (Scala 2 only) |\n| `kebs-pekko-http` | Pekko HTTP unmarshallers + path matchers |\n| `kebs-http4s` | http4s path/query parameter codecs |\n| `kebs-http4s-stir` | http4s-stir directives + path matchers |\n| `kebs-scalacheck` | `Arbitrary` instance generation |\n| `kebs-pureconfig` | PureConfig `ConfigReader` / `ConfigWriter` |\n| `kebs-jsonschema` | JSON Schema generation (Scala 2 only) |\n| `kebs-baklava` | Baklava schema + parameter support |\n| `kebs-tagged` | Tagged types for Scala 2 |\n| `kebs-tagged-meta` | `@tagged` code generation (Scala 2 only) |\n| `kebs-opaque` | Opaque type support for Scala 3 |\n| `kebs-enum` | Scala 3 native enums + Scala 2 `Enumeration` |\n| `kebs-enumeratum` | Enumeratum support (Scala 2 \u0026 3) |\n| `kebs-instances` | Pre-built converters for `java.time`, `UUID`, `URI`, etc. |\n\n### Kebs 2.0 migration guide\n\n* Mix in `CaseClass1ToValueClass` if you use value classes.\n* Extend value-enums with `ValueEnumLikeEntry[V]`.\n* Use `KebsEnumeratum` / `KebsValueEnumeratum` for Enumeratum, `KebsEnum` / `KebsValueEnum` for native enums.\n* See the [full documentation](https://theiterators.github.io/kebs/) for details.\n\n### IntelliJ support\n\n[Kebs for IntelliJ](https://plugins.jetbrains.com/plugin/16069-kebs) plugin adds support for `@tagged` generated code.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftheiterators%2Fkebs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftheiterators%2Fkebs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftheiterators%2Fkebs/lists"}
