> This creates a simple web app for Drupal 8.
To use jDrupal directly on the Drupal front end, see the [Drupal Example page](Examples/Drupal).
## 1. Set up the jDrupal Module
[Enable and Configure](Install) the jDrupal module for your Drupal 8 site.
## 2. Create an app folder
Next, create a folder called `app` to store your application's source code. This folder should live within the same domain as your Drupal website. For example, place it in a new directory called `app` in your Drupal root:
```
http://example.com/app
```
## 3. Download jDrupal
[Download](https://raw.githubusercontent.com/signalpoint/jDrupal/8.x-1.x/jdrupal.min.js) the tool kit so it lives here:
```
http://example.com/app/jdrupal.min.js
```
## 4. Add an index.html file
Next, create an `index.html` file to start your app.
`http://example.com/app/index.html`
```
jDrupal
Loading...
```
## 5. Add an app.js file
Next, create an `app.js` file to run your app and replace the `sitePath` value with the URL to your Drupal website.
`http://example.com/app/app.js`
```
// Set the Drupal site path.
jDrupal.config('sitePath', 'http://example.com');
function helloWorld() {
// Connect to Drupal.
jDrupal.connect().then(function() {
// Grab the current user account.
var user = jDrupal.currentUser();
// Prepare a message for the user.
var text = 'Hello World';
if (user.isAuthenticated()) {
text = 'Hello ' + user.getAccountName();
}
// Show the message in the paragraph.
document.getElementById("msg").innerHTML = text;
});
}
```
## 6. Run the app
Navigate to `http://example.com/app` to view the `Hello World`.
