rad4s

High velocity Scala. A set of utilities to speed up rendering, storage, testing, and prototyping.

chirps

Storage engine using JSON and plain files with a degree of concurrency support.

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "chirps" % "0.0.38"

chirps2

Similar to chirps, but uses a default value.

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "chirps2" % "0.0.38"

doobie-postgres-json-circe-type

Directly embed a Circe-compatible type into Doobie queries for PostgreSQL.

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "doobie-postgres-json-circe-type" % "0.0.41"

es1

Event-streamed storage engine for NDJson and PostgreSQL.

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "es1" % "0.0.38"

field-names

scala> final case class TestClass(a: String, b: Int)
scala> implicitly[com.scalawilliam.rad4s.fieldnames.FieldNames[TestClass]].fieldNames
List(a, b)

Based on shapeless - especially useful if you'd like to learn how to use shapeless.

Integratable with Kantan to provide headers automatically.

Install with:

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "field-names" % "0.0.38"

http4s-heroku-redirect

Redirect to SSL by default for Heroku apps

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "http4s-heroku-redirect" % "0.0.38"

http4s-jsoup-encoder

Support JSoup Document as a response body in http4s.

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "http4s-jsoup-encoder" % "0.0.41"

http4s-multipart-simple-form

Extract form fields (not files) for easy processing.

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "http4s-multipart-simple-form" % "0.0.41"

http4s-nested-routes

Allow to nest routes within routes. Perfect for conditional routes eg based on user level. This helps lift the security level higher instead at the definition of endpoints.

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "http4s-nested-routes" % "0.0.41"

http4s-resource-servlet

Enabled you to start an HttpApp in http4s, parametrised by ServletConfig, to retrieve things like the context path (to create URLs).

Install with:

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "http4s-resource-servlet" % "0.0.38"

mage

Reflection-free dynamic dispatch. Using Scala macros.

I use it to create new menu items and routes in my http4s applications without having to create them explicitly. They typically have method signature like IO[Response[IO]].

scala> trait ExampleTrait {
  def callX: String = "X"
  def callY: String = "Y"
  def callZ: Int = 3
}

scala>  val tCalls = com.scalawilliam.rad4s.mage.Mage.mage[ExampleTrait, String]
val tCalls: scala.collection.immutable.Map[String,ExampleTrait => String] = Map(callX -> $Lambda$7225/0x00000001016ec840@5d92cfa6, callY -> $Lambda$7226/0x00000001016eb840@6efc083e)

Install with:

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "mage" % "0.0.38"

magtags

Render HTML tables with Magnolia and Scalatags

resolvers in ThisBuild += Resolver.bintrayRepo("scalawilliam", "maven")
libraryDependencies += "com.scalawilliam.rad4s" %% "magtags" % "0.0.43"
