To use tapir, add the following dependency to your project:
"com.softwaremill.sttp.tapir" %% "tapir-core" % "0.13.0"
This will import only the core classes needed to create endpoint descriptions. To generate a server or a client, you will need to add further dependencies.
Most of tapir functionalities are grouped into package objects which provide builder and extensions methods, hence it’s easiest to work with tapir if you import whole packages, e.g.:
If you don’t have it already, you’ll also need partial unification enabled in the compiler (alternatively, you’ll need to manually provide type arguments in some cases). In sbt, this is:
scalacOptions += "-Ypartial-unification"
and see where auto-complete gets you!
