You can build your Dancer application piece-by-piece, you can also kick-start your application by creating a skeleton. 

dancer -a My::App

This will create a directory called My-App with the following structure: 

My-App/
├── bin
│   └── app.pl
├── config.yml
├── environments
│   ├── development.yml
│   └── production.yml
├── lib
│   └── My
│       └── App.pm
├── Makefile.PL
├── MANIFEST
├── MANIFEST.SKIP
├── public
│   ├── 404.html
│   ├── 500.html
│   ├── css
│   │   ├── error.css
│   │   └── style.css
│   ├── dispatch.cgi
│   ├── dispatch.fcgi
│   ├── images
│   └── javascripts
│       └── jquery.min.js -> /usr/share/javascript/jquery/jquery.min.js
├── t
│   ├── 001_base.t
│   └── 002_index_route.t
└── views
    ├── index.tt
    └── layouts
        └── main.tt

You can now cd into the My-App directory and run: 

plackup bin/app.pl

Then visit http://localhost:5000/ to see your application.
