Getting Clojure

In the Wild

So far we have limited ourselves to the built-in libraries that come packaged with Java. But Clojure’s interop features work just as well with third-party libraries. For example, you might be interested in using Google’s take on reading and writing JSON, the Gson library.^[29]

To get a feel for using Gson from Clojure, you might start by creating a new project:

$ lein new exploregson

Generating a project called `exploregson`...

$ cd exploregson
