Learning ClojureScript

By: W. David Jarvis, Allen Rohner

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.

Preface

AJAX


Let's continue extending our Todo app. Now, we'd like to persist our todo items on the server. To get the job done only takes a simple Clojure REST API—that said, it still will take some work.

If you'd like to avoid all typing and just read along, we've created a Git repo on GitHub at https://github.com/learningclojurescript/code-examples . You can just clone the repo and get ready to go.

Dependencies

Let's open the project.clj file in our om-tut directory and add some entries:
