Overview of this book

Clojure is an expressive language that makes it possible to easily tackle complex software development challenges. Its bias toward interactive development has made it a powerful tool, enabling high developer productivity. In this book, you will first learn how to construct an interactive development experience for ClojureScript.. You will be guided through ClojureScript language concepts, looking at the basics first, then being introduced to advanced concepts such as functional programming or macro writing. After that, we elaborate on the subject of single page web applications, showcasing how to build a simple one, then covering different possible enhancements. We move on to study more advanced ClojureScript concepts, where you will be shown how to address some complex algorithmic cases. Finally, you'll learn about optional type-checking for your programs, how you can write portable code, test it, and put the advanced compilation mode of the Google Closure Compiler to good use.

Chapter 1. Getting Ready for ClojureScript Development

ClojureScript's promise is to bring the expressiveness and agility of the Clojure programming language to JavaScript developers. Having such power at hands means that teams working on single page applications—and on Node.js services as well—more productivity and less frustration.

But to be able to take complete advantage of this platform, we must grasp its inner mechanisms and, sometimes patiently, work our way towards the perfect ClojureScript live-coding environment. In this chapter, we'll cover the material necessary to achieve this objective.

We'll begin by studying the ClojureScript ecosystem, focusing on its compiler internals and talking about the Read-Eval-Print-Loop (REPL) it offers. We'll then present some alternative building blocks that make it possible to expose interactive ClojureScript development work-flows through third-party tools. We'll finally leverage all of this knowledge in order to build full-fledged, integrated, and interactive ClojureScript development environments. To get started with adopting this approach, we'll discuss the following:

  • Getting familiar with the ClojureScript ecosystem
  • Live coding ClojureScript on top of nREPL with PiggieBack and Weasel
  • Live coding ClojureScript with Figwheel
  • Setting up Emacs for ClojureScript development
