Quickstart

The main sttp API comes in a single jar without transitive dependencies. This also includes a default, synchronous backend, which is based on Java’s HttpURLConnection. For production usages, you’ll often want to use an alternate backend (but what’s important is that the API remains the same!). See the section on backends for additional instructions.

Using sbt

The basic dependency which provides the API and the default synchronous backend is:

"com.softwaremill.sttp" %% "core" % "1.4.2"

sttp is available for Scala 2.11 and 2.12, and requires Java 8. The core module has no transitive dependencies.

sttp is also available for Scala.js 0.6. Note that not all modules are compatible and there are no backends that can be used on both.

Using Ammonite

If you are an Ammonite user, you can quickly start experimenting with sttp by copy-pasting the following:

import $ivy.`com.softwaremill.sttp::core:1.4.2`
import com.softwaremill.sttp.quick._
sttp.get(uri"http://httpbin.org/ip").send()

Importing the quick object has the same effect as importing com.softwaremill.sttp._, plus defining an implicit synchronous backend (val backend = HttpURLConnectionBackend()), so that sttp can be used right away.

Imports

Working with sttp is most convenient if you import the sttp package entirely:

import com.softwaremill.sttp._

This brings into scope the starting point for defining requests and some helper methods. All examples in this guide assume that this import is in place.

And that’s all you need to start using sttp! To create and send your first request, import the above, type sttp. and see where your IDE’s auto-complete gets you! Or, read on about the basics of defining requests.
