Description

Clojure is a functional hosted LISP known for its expressiveness, which has excellent interop with Javascript, Java, and Microsoft’s Common Language Runtime (CLR).

Many developers praise the elegance and productivity Clojure allows, but for many it seems like an esoteric language with an “ugly” syntax that is impossible to get started with. This course will change that view and show you how to be productive with this marvelous language.

In this course, we’ll build a web-based graphics editor similar to Canva. We’ll explore Clojure from the perspective of a JavaScript developer. Along the way, we’ll also explore state management, authentication, API integration with Google Firebase and interop with NPM.

This course takes you from zero to an understanding of Clojure semantics, LISP tools, and building a production-ready React application in just a few hours.

We’ll start with the basics and build up to writing a fullstack app with both frontend and backend in Clojure.

The frontend, built using ClojureScript (Clojure that runs on JavaScript) will be a single page React application with routing, key-based authentication and API integration, which will save, list, edit and delete graphics.

The backend is hosted on Google Firebase.

Throughout the course, we’ll learn about tools like REPL that aid development. Towards the end, we’ll learn about advanced concepts like code splitting and end-to-end testing.

Clojure is unlike other languages as it is hosted on, and can leverage, existing VMs. This means that you can learn Clojure once and write it on the backend with JVM or CLR, and the frontend with JavaScript. If a new technology like Rust takes over the world tomorrow, you will probably be able to continue to write Clojure because a Rust port is already in the making.

By the end of this course, you’ll have a superpower: the ability to write fullstack Clojure applications.
