sttp is a family of Scala HTTP-related projects, and currently includes:

• sttp client: The Scala HTTP client you always wanted!
• sttp tapir: Typed API descRiptions
• sttp model: this project. Simple Scala HTTP model. Used by sttp client & sttp tapir

Quickstart with sbt

Add the following dependency:

"com.softwaremill.sttp.model" %% "core" % "1.4.23"

sttp model is available for Scala 2.11, 2.12, 2.13, 3.0.0, Scala.JS and Scala Native.

Project content

Available model classes include:

• Uri
• Method
• StatusCode
• MediaType
• Header
• HeaderNames
• QueryParams
• body fragments:
  • Part
  • ServerSentEvent
• header values:
  • Accepts
  • Accept-Encoding
  • CacheDirective
  • Cookie
  • ETag
  • Range
  • ContentRange
  • WWWAuthenticateChallenge

Most classes contain both serialisation & parsing functionality, following these conventions:

• .toString returns a representation of the model class in a format as in an HTTP request/response. For example, for an uri this will be http://..., for a header [name]: [value], etc.
• [SthCompanionObject].parse(serialized: String): Either[String, Sth]: returns an error message, or an instance of the model class
• [SthCompanionObject].unsafeApply(values): creates an instance of the model class; validates the input values and in case of an error, throws an exception. An error could be e.g. that the input values contain characters outside the allowed range
• [SthCompanionObject].safeApply(...): Either[String, Sth]: same as above, but doesn't throw exceptions. Instead, returns an error message, or the model class instance
• [SthCompanionObject].apply(...): Sth: creates the model type, without validation, and without throwing exceptions

Documentation

Javadocs

The docs for sttp client contain documentation for the model classes: overview, uri interpolator.

Building & testing the scala-native version

By default, sttp-native will not be included in the aggregate build of the root project. To include it, define the STTP_NATIVE environmental variable before running sbt, e.g.:

STTP_NATIVE=1 sbt

You might need to install some additional libraries, see the scala native documentation site.
