Bread::Board::Manual - A manual for Bread::Board
VERSION¶
version 0.32
INTRODUCTION¶
As we have said, Bread::Board is an inversion of control framework with a focus
on dependency injection and lifecycle management. The goal that Bread::Board
strives towards is to promote more decoupled designs. It does this by removing
the need for your objects to be concerned with resolving and/or creating their
dependencies as well as knowing (or caring) what their lifecycle is.
Why should I use Bread::Board¶
First, it should be noted that Bread::Board and IoC are not universally useful.
Smaller applications and one-off scripts would be overburdened by the
abstractions of Bread::Board. But the larger your application becomes, the
more something like Bread::Board can help.
As applications grow so the management of resources and their dependencies
becomes more of a burden. Making sure all your components are properly
initialized, in the right order and at all times that you need them, can
become a twisty maze. Bread::Board is intended to help you manage this twisty
maze and remove the need for you to manage this manually.
Take your typical Catalyst application, the Catalyst framework itself contains
its own mini IoC framework through the component subsystem. Catalyst will
manage your models and views making sure that they will be available when you
need them in the controllers. Catalyst makes all this easy to manage through
its configuration system. This is great inside your Catalyst application, but
what about outside of it? Any sufficiently complex web application will have a
set of scripts and/or command-line applications to help support it. At this
point you are left to your own devices and must manage these components and
their dependency chains on your own.
By decoupling IoC into its own stand-alone subsystem it becomes possible to get
that same ease-of-use you get inside something like a Catalyst application,
outside of it.
This, in a nutshell, is what Bread::Board aims to provide.
SECTIONS¶
- Bread::Board::Manual::Concepts
- This is perhaps the best place to start, it will introduce you to the
basic concepts that make up Bread::Board.
- Bread::Board::Manual::Concepts::Typemap
- With Bread::Board you provide names for your service so that you can find
them later. This document explores the new (read: experimental) typemap
feature which allows you to map services to types as well.
- Bread::Board::Manual::Concepts::Advanced
- Bread::Board is an extensible and open system, this document will explore
how you can extend Bread::Board and get greater re-use of your
components.
- Bread::Board::Manual::Example
- This is a set of examples meant to show how Bread::Board can be used in
real-world scenarios. It is recommended that you read the above
documentation first as many of these examples use the concepts discussed
in them.
