Reading and writing JSON in Clojure

Clojure is a modern Lisp variant running on top of the Java and Microsoft Common Language Runtime (CLR) platforms. As such, you can use the facilities we discussed in Chapter 1, Reading and Writing JSON on the Client, to convert between JSON and objects in the native runtime, but there's a better way, and that is the Clojure's data.json module, available at https://github.com/clojure/data.json.

Getting ready

To begin, you need to specify your dependency in the data.json module. You can do this with the following dependency in your Leiningen file:

[org.clojure/data.json "0.2.5"]

If you're using Maven, you'll want this:

<dependency>
<groupId>org.clojure</groupId>
<artifactId>data.json</artifactId>
<version>0.2.5</version>
</dependency>

Tip

Of course, the version of data.json may change between the time I write this and the time you include it in your project as a dependency. Check...
