To check if your form works, you can follow these steps:

1. Start your Clojure API: Run your Clojure API using lein run or java -jar your-jar-file.jar (depending on how you're running your API).

2. Open your web page: Open a web browser and navigate to http://localhost:3000 (or the URL where your API is running). You should see your HTML form.

3. Fill out the form: Fill out the form with some sample data, such as:

Name: John Doe
Sex: Male
Date of Birth: 1990-01-01
Address: 123 Main St
Social Security Number: 123-45-6789

4. Submit the form: Click the "Add Patient" button to submit the form.

5. Check the API response: Check the API response in the browser's developer tools (e.g., Chrome DevTools) or using a tool like Postman.

6. Verify the patient was added: Check your database or API logs to verify that the patient was successfully added.

7. Test error scenarios: Test error scenarios, such as:

Leaving a required field blank
Entering invalid data (e.g., invalid date format)
Submitting the form with an existing patient's details

By following these steps, you can verify that your form is working correctly and your API is processing the form data as expected.

Here's an example of how you can add a route and a UI component to add a patient:

Add a route to add a patient

In your routes.clj file, add the following route:

(defroutes patient-routes
  (POST "/patients" request (add-patient-handler request)))

(defn add-patient-handler [request]
  (let [params (:params request)
        name (:name params)
        sex (:sex params)
        date-of-birth (:date-of-birth params)
        address (:address params)
        social-security-number (:social-security-number params)]
    (try
      (add-patient name sex date-of-birth address social-security-number)
      (response "Patient added successfully!")
      (catch Exception e
        (response (str "Error adding patient: " (.getMessage e)) 500)))))

This route listens for a POST request to /patients and calls the add-patient-handler function. The handler extracts the parameters from the request, calls the add-patient function, and returns a response indicating whether the patient was added successfully or not.

Add a UI component to add a patient

Create a new file add_patient.html in your resources/public directory:

<!DOCTYPE html>
<html>
  <head>
    <title>Add Patient</title>
  </head>
  <body>
    <h1>Add Patient</h1>
    <form action="/patients" method="post">
      <label for="name">Name:</label>
      <input type="text" id="name" name="name"><br><br>
      <label for="sex">Sex:</label>
      <input type="text" id="sex" name="sex"><br><br>
      <label for="date-of-birth">Date of Birth:</label>
      <input type="date" id="date-of-birth" name="date-of-birth"><br><br>
      <label for="address">Address:</label>
      <input type="text" id="address" name="address"><br><br>
      <label for="social-security-number">Social Security Number:</label>
      <input type="text" id="social-security-number" name="social-security-number"><br><br>
      <input type="submit" value="Add Patient">
    </form>
  </body>
</html>

This is a simple HTML form that allows the user to input the patient's details. When the form is submitted, it sends a POST request to /patients with the input data.

Update your handler.clj file

Add a route to serve the add_patient.html file:

(defroutes app-routes
  ...
  (GET "/add-patient" [] (resource-response "add_patient.html" {:root "public"}))
  ...)

This route serves the add_patient.html file when the user navigates to /add-patient.

That's it! Now you should be able to add a patient by navigating to /add-patient in your browser, filling out the form, and submitting it.

To add a UI component to get all patients, you'll need to create a web interface that interacts with your CRUD API. One way to do this is by using a ClojureScript library like Reagent or Rum, which allow you to create reactive UI components.

Here's an example of how you could create a simple UI component using Reagent to display all patients:

First, add the necessary dependencies to your project.clj file:

(defproject hs-clojure "0.1.0-SNAPSHOT"
  ...
  :dependencies [[org.clojure/clojure "1.10.0"]
                 [org.clojure/clojurescript "1.10.520"]
                 [reagent "0.8.1"]
                 ...])

Create a new namespace for your UI component:

; src/cljs/hs_clojure/ui.cljs
(ns hs-clojure.ui
  (:require [reagent.core :as r]
            [cljs-http.client :as http]
            [cljs.core.async :refer [<! >!]])
  (:import [goog Uri]))

(defonce patients (r/atom []))

(defn get-all-patients []
  (http/get "/api/patients"
             {:handler (fn [response]
                         (reset! patients response))}))

(defn patient-list []
  [:ul
   (for [patient @patients]
     ^{:key patient} [:li (:name patient)])])

(defn main-panel []
  [:div
   [:h1 "Patients"]
   [patient-list]
   [:button {:on-click get-all-patients} "Get All Patients"]])

(defn ^:export main []
  (r/render [main-panel]
            (.getElementById js/document "app")))

Create an HTML file to render the UI component:

<!-- resources/public/index.html -->
<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>HS Clojure</title>
  </head>
  <body>
    <div id="app"></div>
    <script src="js/main.js"></script>
  </body>
</html>

Update your handler.clj file to include the API endpoint for getting all patients:

; src/hs_clojure/handler.clj
(ns hs-clojure.handler
  ...
  (:require [hs-clojure.patients :as patients]))

(defroutes app-routes
  ...
  (GET "/api/patients" [] (patients/get-all-patients))
  ...)

Start your ClojureScript compiler and web server:

lein cljsbuild once
lein ring server

Open your web browser and navigate to http://localhost:3000. You should see a simple UI component that displays a list of patients when you click the "Get All Patients" button.

Note that this is just a basic example to get you started. You'll likely want to add more features, error handling, and styling to your UI component.

To add a Reagent UI to your project, you'll need to create a new namespace for your UI components and use Reagent's atom and render functions to create a reactive UI.

Here's a step-by-step guide to get you started:

1. Add Reagent to your project

In your project.clj file, add the following dependency:

[reagent "0.10.0"]

2. Create a new namespace for your UI components

Create a new file src/hs_clojure/ui.cljs with the following content:

(ns hs-clojure.ui
  (:require [reagent.core :as r]
            [reagent.dom :as rd]))

3. Create a UI component

In the hs_clojure.ui namespace, create a simple UI component, such as a patient list:

(defn patient-list []
  (let [patients (r/atom [])]
    (fn []
      [:div
       [:h1 "Patients"]
       [:ul
        (for [patient @patients]
          [:li (:name patient)])]
       [:button {:on-click #(fetch-patients!)} "Fetch patients"]]))

(defn fetch-patients! []
  (GET "/api/patients" {:handler (fn [response]
                                  (reset! patients response))}))

This component uses an atom patients to store the patient data and a fetch-patients! function to retrieve the data from your API.

4. Create a Reagent app

Create a new file src/hs_clojure/app.cljs with the following content:

(ns hs-clojure.app
  (:require [hs-clojure.ui :as ui]
            [reagent.core :as r]))

(defn app []
  [ui/patient-list])

(r/render [app] (.getElementById js/document "app"))

This file defines a Reagent app that renders the patient-list component.

5. Update your HTML file

Create a new file resources/public/index.html with the following content:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>HS Clojure</title>
  </head>
  <body>
    <div id="app"></div>
    <script src="js/compiled/app.js"></script>
  </body>
</html>

This file sets up an HTML page with a div element that will be used to render the Reagent app.

6. Compile your ClojureScript code

Add the following configuration to your project.clj file:

:cljsbuild
{:builds
 {:app {:source-paths ["src/hs_clojure"]
        :compiler {:output-to "resources/public/js/compiled/app.js"
                   :optimizations :advanced
                   :pretty-print false}}}}

This configuration tells ClojureScript to compile your app.cljs file and output the compiled JavaScript code to resources/public/js/compiled/app.js.

7. Run your application

Run lein cljsbuild once to compile your ClojureScript code. Then, start your Ring server with lein ring server. Open your web browser and navigate to http://localhost:3000 to see your Reagent UI in action!

This is just a basic example to get you started. You'll need to modify the UI components and API endpoints to fit your specific requirements. requires #9
