The easiest way to write a webapp with Perl
=== ABOUT ===
This project is inspired by Ruby's Sinatra framework: a framework for building
web applications with minimal effort, allowing a simple webapp to be created with
very few lines of code, but allowing the flexibility to scale to much more
complex applications. Dancer supports plugins to add various extra
functionality you may want, whilst keeping the core streamlined.
=== NEWS ===
Dancer's development moves very quickly, to stay tuned follow PerlDancer on

To keep even more up to date and talk to the developers, join us in #dancer on (if you don't have an IRC client, use
for easy access).
=== EXAMPLE ===
To create a new Dancer application, use the helper script "dancer" provided
with this distribution:
$ dancer -a mywebapp
+ mywebapp
+ mywebapp/config.yml
+ mywebapp/views
+ mywebapp/views/layouts
You then have a new Dancer application in 'mywebapp', which is already a
functioning "Hello World" application, ready for you to work upon.
Here is an example of a webapp built with Dancer:
use Dancer;
get '/' => sub {
"Hello There!"
get '/hello/:name' => sub {
"Hey ".params->{name}.", how are you?";
post '/new' => sub {
"creating new entry: ".params->{name};
When running this script, a webserver is running and ready to serve:
$ perl ./
>> Listening on
== Entering the development dance floor ...
Then it's possible to access any route defined in the script:
$ curl http://localhost:3000/
Hello There!
For a more in-depth example, see examples/dancr
Dancer depends on the following modules
- HTTP::Server::Simple::PSGI
- HTTP::Body
- Exception::Class
- MIME::Types
Optional modules may be needed if you want to use some features (but are not
required for a basic usage).
Dependency-checks for additional features are performed at runtime.
Most common modules you may want are:
- Template (for Template::Toolkit support)
- YAML (for configuration files)
- Plack (if you want to deploy your application with PSGI)
This is a work in progress.
Dancer supports PSGI/Plack, to run a Dancer app with PSGI/Plack just bootstrap
your application with the helper script `dancer' like the following:
$ dancer -a MyWebApp
You'll find a file in there called `app.psgi', use this file to configure your
PSGI environment, as explained in the revelant documentation of your PSGI
For instance, with plackup, just do the following:
$ plackup -a app.psgi
