Step by step guide for publishing a library to clojars repository by
ATTENTION NOTE: I'm in the process of publishing the second edition of the series. The main difference from the first edition regards the use of the Boot build tool instead of Leiningen. This second edition is still a draft version and you should be forgiving if you find errors, typos or even bugs in the code.
WARNING NOTE FOR WINDOWS USERS: At the moment
bootdoes not run on MS Windows less than 10. If this is your case, to be able to follow the
modern-cljsseries you can use use a virtual machine or docker linux container.
Modern ClojureScript (
modern-cljs) is a series of tutorials that
guide you in creating and running ClojureScript (CLJS) projects.
If you don't know anything about Clojure (or about Lisp), I recommend you learn a little bit before starting these tutorials.
There are plenty of outstanding resources on Clojure that are freely available on the Internet, and you can't overestimate the benefit of reading a book on Clojure (or another Lisp dialect) to your value as a programmer.
Here are some book recommendations:
- Clojure Programming: written by three of the heroes of Clojure, it contains everything you need to know about Clojure and its ecosystem.
- Programming Clojure: written by another legendary Clojure developer, it's the easiest path to learning Clojure.
- The Joy of Clojure: the title speaks by itself. A must read!
- ClojureScript Rationale and ClojureScript Quick Start
- SICP - Structure and Interpretation of Computer Programs: this is the best programming book I've read in my very long career. It uses Scheme/Racket (a Lisp dialect) rather than Clojure and is available online, in print, or in a lecture series.
- On Lisp: if you want to learn about macros, this is the place to start. It uses Common Lisp (a Lisp dialect) rather than Clojure.
Many people worry about which operating system and editor/IDE are best for developing in Clojure and ClojureScript. I personally use Mac OS X, Debian and Ubuntu. I use Emacs as an editor.
Because I'm an old-timer, *nix and Emacs are the OS and editor I know best. That being said, in this series of tutorials you're not going to find any suggestions or reference to operating systems or editors. Use whatever tools you already have and know. I have too much respect for people developing IDE/plugins for Clojure/CLJS to say that one is better than another, and you don't want to combine learning a new programming language with trying to learn a new programming environment.
NOTE: If you are interested in learning more about Emacs here are some [resources to help get you started] (https://github.com/magomimmo/modern-cljs/blob/master/doc/supplemental-material/emacs-cider-references.md).

Why the name Modern ClojureScript?
You might wonder why this tutorial series is named
ClojureScript is so recent. I started this series in 2012 while trying
to port a few examples from the
now it's too late to change.
This series of tutorials guides you in creating and running simple CLJS projects. The bulk of the series follows the progressive enhancement of a single project.
While working through the tutorials I strongly suggest you start at tutorial 1 and type in all the code for each tutorial yourself. In my experience this is the the best approach if you're not already very fluent with the programming language.
Create and configure a very basic CLJS project.
Approach as close as possible the Bret Victor Immediate Feedback Principle to build a very interactive development environment.
Automate the launching of the
boot command to approach the Immediate
Feedback Development Environment (IFDE).
Use the Domina library to make our login form validation more Clojure-ish.
Investigate and find two different ways to solve an issue from the last tutorial.
Use Domina events for a more Clojure-ish approach to handling DOM events.
Programmatically manipulate DOM elements in response to DOM events.
Use AJAX to let the CLJS client-side code communicate with the server.
Apply Domina events to the login form example from the 4th Tutorial.
Explore the highest (HTML5) and deepest (Clojure on the server) layers of the login form example from the previous tutorial.
Respect the Don't Repeat Yourself (DRY) principle by sharing validators between the client-side CLJS and the server-side Clojure.
Set the stage for unit testing by learning about the
sytem and starting the shopping calculator example. Use code
refactoring to satisfy the DRY principle and to solve a cyclic
namespaces dependency problem.
Add validators to the
shoppingForm, and do some unit testing.
Configure a development environment that simultaneously satisfy in a single JVM the Immediate Feedback Principle by Bret Victor and the Test Driven Development (TDD).
Make the Test Driven Development Environment more customizable.
Integrate validators into a web form in such a way that the user will be notified with the corresponding help messages when they enter invalid values in the form.
Complete the client-side form validation by exploiting the TDD environment augmented with CLJ/CLJS REPLs.
Explain how to make a library compliant with the new Reader Conditionals extension on CLJ/CLJS compilers.
