I tend to have a Clojure Cheatsheet and a browser always opened on. Of course, the bible, for more fundamental stuffs: Structure and Interpretation of Computer Programs (A good PDF and EPUB version are available). If you have a Java/OO background I suggest you to read Functional Programming for the Java Developer and Functional Programming for the Object Oriented Programmer. The recent Clojure Applied by Alex Miller is great to navigate into the Clojure landscape (by the way have a look at clojure.spec that aims to same requirement than the Schema library).įor those of you that prefer a more “example oriented” approach, have a look at the nice Clojure Cookbook. If you begins with functional programming I suggest you to start with Clojure Programming from Christophe Grand, O’Reilly, once more experienced you can follow with the amazing Joy of clojure for hindsightful thoughts about programming applied with clojure ( a 2nd edition is out). When learning Clojure, first of all: have great resources to rely on and not get lost. I focus on the practical tips that will allow you to start seamlessly on Mac Os X (but should apply with Linux and Windows). In it, and you should see the same results as the inline comments show.In this article, I share my experience of developing with Clojure over the last years. You can try the code out in the comment form by evaluating each expression Each mapĮntry's key is a column name (as a Clojure keyword), and its value is Note that sql/query returns a vector of maps. ![]() (assert (and (map? results) (:LOCATIONS/ID results))) The deps.edn file should have the following contents: )] ![]() In a new folder, perhaps called my-webapp, we're going to create a deps.ednįile to specify the libraries we want to use, and a couple of folders: oneįor CSS files and one for your source code. So you can how see how all the moving parts work. ![]() We're going to create this project from scratch and use the Clojure CLI It uses a single file for storage, but also could be run as in-memory DB.Īnother similar Java-based embedded DB that could be used in yourĪpplication is Apache Derby. expands to (and so, is the same as if you wrote)ĭatabase that could be embedded in your application or run in server It automatically unpacks seqs for you, for example: It provides some CSS-like shortcuts for specifying id and class, For example, " Jones."]īut it also does two extra handy bits of magic: It converts regular Clojure data structures right into To take care of this for us such that we can associate url paths withĬorresponding functions, all in one place.Ĭlojars) provides a quick and easy way to Take that incoming request map and then delegate to various functions If we were using only Ring, we'd have to write one single function to
