I used the following versions to do this stuff
» sbt --version
sbt launcher version 0.12.4
» scalac -version
Scala compiler version 2.10.2 -- Copyright 2002-2013, LAMP/EPFL
We wanted to setup a server that uses spray to do RESTful API's. So, we
started out with Age's template build.sbt, then extended this to a
minimal "hello world" with GET and PUT handlers.
Step one:
» sbt
> compile
or simply
» sbt run
Then,
» curl localhost:5000/hello
hello, world!%
» curl-XPUT localhost:5000/hello
foo, bar!%
Later we extended it with JSON (un)marshalling from(to) a case class.
For this we used another bit of Age's code, to directly pass a
Marshallable JSON object to the complete directive of spray.
Step two:
curl ... {"hello": "world"}
