![]() ![]() We started with a default Ring server running on Jetty and updated our project. We selected Light Table as our editor and have been pretty happy with it so far. First we need some prerequisites: Leiningen, JDK, CouchDB, and a Clojure-friendly editor. Weâll discuss light-weight data modeling more in a future article. SPAs have freed us from statically typed rendering logic and boiler plate domain to data transfer object (DTO) mapping code. Our SPA front-end is based on Javascript, and as a dynamic language, Javascript is far more accepting and malleable to change in our business data models. zip version of the Java Development Kit 12, extract it, and run. If you donât have Java installed, download the Windows. If you get reasonable output, Java is already installed and you can move on to the next step. by typing win+r cmd) and type java -version.Just as single page applications have reduced our application-tier complexity, they have also changed our approach to data modeling. First, check if you have Java installed already. As a document store, CouchDB fits nicely in our example since it maps directly to and from Clojureâs lists, sets, and maps. We wanted the data storage back-end for this example to complement Clojureâs focus on data-structures. In our second article weâll demonstrate a simple SPA using Om building upon the Clojure JSON REST API presented here. Clojure checks the box as a solution we can deploy on the JVM, and in this article weâll explore our experience building a simple API to store and load JSON documents.Īs an added benefit, Clojureâs immutable data structure philosophy has influenced Om, a high-performance client-side rendering framework based on React. We feel Clojure's functional programming and data structure philosophy are a better match for our style of thin server architectures. We reviewed many options like jRuby and Scala, but selected Clojure. Having covered three of the biggest interpreted runtimes in the CLR, V8, and Ruby, we recently wanted to deliver a back-end solution for the JVM. As the back-end has lost logic and responsibilities we care less and less about which technology stack we select for the solution. Weâve built thin SPA back-ends in Microsoft ASP.Net MVC, ASP.Net Web API, NodeJS with Express, and Ruby with Sinatra and Rails. We increasingly think of the application tier as plumbing, only responsible for data storage with a little authentication, authorization, and validation thrown in. Weâve moved to a thin server architecture for delivering our back-end solutions on SPA projects. As weâve written more and more SPAs an unexpected trend has emerged. Fantastic client-side Javascript frameworks like AngularJS, Knockout, and React have made the transition easy and fun. INTELLIJ'S LA CLOJURE La Clojure is an IntelliJ plugin for Clojure development.It is probably the most used tool for Clojure development right now, and it's the most mature Clojure plugin for a major IDE right now.The single page application (SPA) approach has revolutionized our approach to development. (Does not need any previous Clojure installation) Hope this gets better and better with everybody's help, because Nightcode is open source at GitHub. It's still a new project (current version is 0.0.1) so the IDE itself is pretty simple for now, the available options are pretty basic, but it looks very promising, specially for focusing on such a future language as Clojure. The IDE offers several options for a new project: It is itself is a JAR file made mostly in Clojure, with some Java parts. A very very interesting project, Nightcode aims at creating an IDE for Clojure (and Java too, but really the Clojure part is what is interesting).
