In Perl, web development is typically done using CGI (Common Gateway Interface) or by building web applications through frameworks.

  1. CGI, or Common Gateway Interface, is a standard interface used to create dynamic web pages. You can write Perl scripts to handle web requests, generate HTML, and send it back to the browser. By utilizing the CGI module in Perl scripts, you can easily handle form submissions, URL parameters, and other web requests.

Example code:

#!/usr/bin/perl
use CGI;
my $cgi = CGI->new;
print $cgi->header;
print $cgi->start_html("Hello World");
print $cgi->h1("Hello World");
print $cgi->end_html;
  1. Frameworks in Perl like Dancer, Mojolicious, and Catalyst offer a more structured and advanced approach to building web applications, including features like routing, template engines, and database integration.

Sample code (using the Dancer framework):

use Dancer;
get '/' => sub {
    return "Hello World";
};
dance;

Whether you choose to use CGI or frameworks, Perl is a powerful tool for web development. You can choose the method that best suits your project requirements and personal preferences to build web applications.
