Developing with om.next, the next-generation ClojureScript library

In this recipe, we will learn David Nolen's om to build a ClojureScript application. Om is a ClojureScript library to interact with React. React is a very famous JavaScript library developed by Facebook. React enables developments of user interfaces simpler and reusable UI components.

Recently, Nolen started to develop om.next. It's a successor of om and inspired by Facebook's Relay, Netflix's Falcor, and Cognitect's Datomic. It is still alpha but it is worth digging it. The project.clj of om.next is as follows:

https://github.com/omcljs/om/blob/master/project.clj

Getting ready

Before learning om.next, we will create and set up a new project named om-next-example.

Creating a new project for om.next

To create a new project for om.next, issue the following command:

$ lein new figwheel om-next-example -- --om

Updating the om version

Go to the om-next-example directory and update the om version in your project.clj to enable om.next...
