Clojure API Rest

This is a study case to create an API Rest using Clojure.

The objective is learn more about how Clojure works and principally, concepts of functional programming.

Usage

First install Leiningen in http://leiningen.org/. On Ubuntu, follow de instructions:

$ wget https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein
$ chmod +x lein
$ sudo mv lein /usr/local/bin

After download this repository, open clojure-api-rest and run lein ring server.

• Show error message with correct status when product does not exists
• Create gateway product
• Test gateway product
• Config database test
• Resource tests (? controller test)
• Config Datomic

Create database

create database clojure_api_rest;

Create table product
