Patient Encounter notification Application

In this tutorial, we will create a simple application written on Clojure programming language using Aidbox Clojure SDK and Aidbox.cloud or Aidboxone as a backend.
All source code available on Github Aidbox/app-mailgun-clj​
Problem statement
We have a Encounter included Patient, date and location of visit.
We want to send an Email to a patient with a notification of the upcoming visit. In this email we want to show the Patient information, time and location of the visit. These notifications should be sent the day before the visit.
Architecture
Aidbox as backend which will store all Encounters. .....
Clojure application with Aidbox Clojure SDK as a connector between our application and backend.
For sending Emails we will use MailGun service as the easiest way to send emails instead SMPT.
Architecture of Aidbox based Application
Get started
Firstly, you need to install local Aidbox. See the full instruction on how to install Aidbox locally and how to use Rest API​
In this sample application, we use Clojure CLI. See Getting Started for details on how to install the tools.
Enable Aidbox SDK
In this sample app we will use Clojure Cli - command line tools for running REPL and Clojure apps. In deps.end file need specify aidbox-sdk as a reference to git.
deps.edn
{:deps 
  {aidbox-sdk {:git/url "https://github.com/Aidbox/aidbox-clojure-sdk" 
               :sha "057ebd1a542bb17c7a910283ae942f56a89167f1"}}}
And then require aidbox-sdk in the main mailgun.core file
mailgun.core
(ns mailgun.core
  (:require [aidbox.sdk.core :as aidbox]))
Connect your app with Aidbox
For connecting your application with Aidbox, you need call aidbox/call method send them information about the location of Aidbox and your application.
src/mailgun/core.clj
(def manifest
  {:id "mailgun-app"
   :type "app"
   :env {:box {;; host and port of Aidbox instance
               :host "localhost"
               :scheme "http"
               :port 8888}
         :app {;; host, port and client creds of your application
               ;;:host "docker.for.mac.localhost"  ;; for Mac Os
               :host "localhost"
               :scheme "http"
               :port 8989
               :id "root"
               :secret "secret"}}})
​
(defn -main [] (aidbox/start manifest))
How it works?
When you call aidbox/start method, aidbox-sdk try to connect to Aidbox with given env.box.host , env.app.id and env.app.secret credentials and then, if the connection is successful, register your app in Aidbox. After that, aidbox/sdk create local web server running on env.app.port port, in our case is 8989.
