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.
