Who this video course is for

If you are a Java programmer and you want to gain expertise in web application development and would like to begin the journey with Clojure, then this course is perfect for you. For all those of you who already know Clojure, this video will help you sharpen your skills.

In Detail

Web application development has never been as simple and powerful as it will be with Clojure. It runs on both Java Virtual Machine and JavaScript, providing a robust and dynamic programming environment. Clojure brings the code-as-data functionality of Lisp with it and caters to the need of fast-paced coding while making front end-coding easy and viable.

This video course starts with a simple project setup and moves on to the various means to use frameworks or libraries, such as Ring and ClojureScript, leading the way to complex web solutions in Clojure. You will be presented with ways to connect to popular databases, such as PostgreSQL or MongoDB, and learn how some existing libraries work and how to use them properly. Thereon you will move to writing single-page applications with ClojureScript and REST API.

When you're finished with Building Web applications with Clojure, you'll be able to build and diagnose complex web systems in Clojure—regardless of the particular technologies applied.
