Abstract:

This video tutorial provides a rapid demonstration of building a simple web application using Common Lisp. The process utilizes three key libraries: hunch for setting up the web server, spinneret for generating dynamic HTML content via a DSL, and cl-css for generating CSS styles. The video walks through initializing the easy-acceptor server, integrating HTML and CSS generation, and adding functionality to handle a GET parameter to personalize the output message. It highlights the ease and speed with which web applications can be developed in Common Lisp using these libraries.

Building a Web App Quickly in Common Lisp

• 0:00 The video introduces the objective: demonstrating how to quickly build a web app in Common Lisp.
• 0:15 The process begins by setting up a web server using the hunch library.
• 0:26 An instance of easy-acceptor is created and started on port 3333.
• 1:18 HTML generation is incorporated into the application using the spinneret library, which provides a DSL for writing HTML within Lisp code.
• 1:38 Dynamic CSS styling is added using the cl-css library.
• 2:33 The application is enhanced to accept and process a GET parameter named "name" from the URL.
• 3:03 Lisp code is shown demonstrating how to access and use the "name" parameter if provided.
• 3:34 The video concludes by showcasing the completed web application, which generates styled HTML content and can display a personalized greeting based on the "name" GET parameter.
