Running the App

Start the server:

Project Structure

index.js: Main server file that sets up the Express app and handles routes.
views/index.ejs: EJS template file for rendering the main page.
.gitignore: Specifies files and directories to be ignored by Git.
package.json: Contains project metadata and dependencies.

Usage

GET Request

When you navigate to http://localhost:8080, the server will render the index.ejs file and display "Hello World!".

POST Request

The app listens for POST requests at the root URL (/). When a POST request is received, it logs the request body to the console and responds with a JSON message.

Popup Window

The index.ejs file includes a script that opens a popup window to https://lens.admin-host.com and listens for messages from this origin.
When a message is received from the popup, it is logged to the console and displayed on the page.
The message is also sent to the server via a POST request.

Notes

Ensure that the domain you are using is registered with LENS. For testing purposes, you can register localhost.
The server logs the status and received data to the console.
