NAME
Minima - Efficient web framework built with modern core classes
SYNOPSIS
app.psgi
use Minima;
Minima::init;
For a "hello, world":
$ minima run # or plackup app.psgi, as you prefer
And that's it, you've got a functional app. To set up routes, edit
etc/routes.map:
GET / :Main home
POST /login :Login process_login
@ not_found :Main not_found
Controllers:
class Controller::Main :isa(Minima::Controller);
method home {
$view->set_template('home');
$self->render($view, { name => 'world' });
}
Templates:
%% if name
hello, [% name %]
%% end
DESCRIPTION
Minima is a framework for PSGI web applications built with Perl's
new native object-oriented features (perlclass). It is designed to
be simple and minimal, connecting only what is necessary without
getting in the way. Consequently, it's lightweight and fast.
Although designed in a typical MVC fashion, no restrictions are
imposed on design patterns. Controller classes have access to Plack
request and response objects and can interact with them directly.
Minima also provides a class for rendering HTML with ease with
Template Toolkit, but you are free to use your own solution.
To understand the basic principles of how it works, see the
following section in this document. For more about the running
process, check Minima::App. You may also want to visit
Minima::Manual::Customizing to learn how to customize everything
according to your needs.
HOW IT WORKS
A typical web application using Minima operates as follows:
1. Minima::Setup is loaded. It will read a configuration file (if
any, see "Config File" in Minima::Setup) and provides a "init"
subroutine that is passed to Plack as the entry point for
receiving requests.
2. A Minima::App is created and initialized with the supplied
configuration.
3. Minima::App passes a routes file (where all application routes
are defined) to Minima::Router to be read and parsed.
4. The request URL is matched to a route. Minima::App then calls
the appropriate controller and method, setting them up and
passing along the relevant information such as request and route
data.
5. The controller handles the necessary logic, calling models (if
required) and using views (if desired) to produce content.
Content is then assigned to the response and finalized.
GETTING STARTED
To begin a project, the Minima package provides a subroutine
(described below) to help you get started with the process mentioned
above.
You can also interact directly with Minima::Setup for full control
over the setup process.
init
sub init ($config = undef)
A convenience subroutine that calls Minima::Setup::prepare to
prepare the main app object and returns a reference to
Minima::Setup::init.
The optional argument allows you to specify the location of the
configuration file.
For a detailed explanation of behavior and options, refer to the
documentation for Minima::Setup.
EXAMPLE
Minima's repository contains an example application under eg/. To
run it (from the root of the repository), use:
$ cd eg
$ plackup minima.psgi # configure plackup or your server as needed
MANAGING A PROJECT
Included with the distribution you'll find a helper program to
manage projects. See minima for full details.
One of its main features is creating a project from scratch, using
templates with the recommended structure.
$ minima new app
HISTORY
While speaking with Paul Evans about the implementation of class in
Perl's core, he remarked, "You should write a blog post about it."
This led to *Problem #1*: I don't have a blog. Solving that seemed
easy enough, but then came *Problem #2*: there wasn't a web
framework that used the class feature. Naturally, I decided to
tackle *Problem #2* first.
