Enable rapid configuration of Symfony2 project dependencies

Is this for me?

Answer "yes" if those criteria match your requirements:

• developing/maintaining several Symfony projects
• using the same (or subsets of the same) bundles in most projects
• using the same (or subsets of the same) assets in the same places in most projects
• tired of enabling the same bundles and adding the same bundle configuration over and over again for each project
• necessity to keep parts of your projects in sync/up to date: make new bundles or assets available in ALL projects without having to do it manually

This is intended both for rapid development and long-term maintenance of reusable components in your own projects.

What does it do?

ConstructionKitBundle intends to ease project dependency maintenance by providing so-called building blocks that are used inside your projects.

A building block is a single class that provides information about:

• One or more Symfony bundles that are needed by this building block
• Optional YAML default configurations to include
• Optional (pre-filled) YAML configuration files to provide easily editable default configuration
• Optional assets (think js, css, ...), divided into groups that are available as assetic subsets
• Optional parameters to add to parameters.yml and parameters.yml.dist

Building blocks can be auto-installed upon recognition (configurable).

Composer integration

Since ConstructionKit is set out to reduce the amount of manual tampering it allows to register building blocks in composer packages. Packages found by composer will be auto-discovered, so you only have to do 2 things:

• Add composer dependencies and run composer update
• Run app/console construction-kit:refresh to auto-install bundles, configuration and assets

Installation

construction-kit relies on c33s/symfony-config-manipulator-bundle to split and manage configuration files. This will probably refactor most of your configuration structure inside app/config/. Please head over to c33s/symfony-config-manipulator-bundle to learn more and DO NOT FORGET TO COMMIT YOUR CONFIGURATION BEFORE PROCEEDING.

Require c33s/construction-kit-bundle in your composer.json file:

{
    "require": {
        "c33s/construction-kit-bundle": "@stable",
    }
}

or, if you are using 'composer-yaml':

require:
    c33s/construction-kit-bundle:     '@stable'

Register both needed bundles in app/AppKernel.php:

    // app/AppKernel.php

    public function registerBundles()
    {
        return array(
            // ... existing bundles
            new C33s\ConstructionKitBundle\C33sConstructionKitBundle(),
            new C33s\SymfonyConfigManipulatorBundle\C33sSymfonyConfigManipulatorBundle(),
        );
    }

Usage

After enabling both bundles, an initial file setup is needed. Just run the following command: app/console construction-kit:refresh

You will see something like this:

    ######################################################
    #                                                    #
    # The symfony configuration has been changed.        #
    #                                                    #
    # Please re-run the construction-kit:refresh command #
    #                                                    #
    ######################################################

Do as told and run app/console construction-kit:refresh again. Then check the file app/config/config/c33s_construction_kit.map.yml, which should contain the following configuration:

# This file is auto-updated each time construction-kit:refresh is called.
# This may happen automatically during various composer events (install, update)
#
# Follow these rules for your maximum building experience:
#
# [*] Only edit existing block classes in this file. If you need to add another custom building block class use the
#     composer extra 'c33s-building-blocks' or register your block as a tagged service (tag 'c33s_building_block').
#     Make sure your block implements C33s\ConstructionKitBundle\BuildingBlock\BuildingBlockInterface
#
# [*] You can enable or disable a full building block by simply setting the "enabled" flag to true or false, e.g.:
#     C33s\ConstructionKitBundle\BuildingBlock\ConstructionKitBuildingBlock:
#         enabled: true
#
#     If you enable a block for the first time, make sure the "force_init" flag is also set
#     C33s\ConstructionKitBundle\BuildingBlock\ConstructionKitBuildingBlock:
#         enabled: true
#         force_init: true
#
# [*] "use_config" and "use_assets" flags will only be used if block is enabled. They do not affect disabled blocks.
#
# [*] Asset lists will automatically be filled by all assets of asset-enabled blocks. To exclude specific assets, move them to their
#     respective "disabled" sections. You may also reorder assets - the order will be preserved.
#
# [*] Assets are made available through assetic using the @asset_group notation.
#
# [*] Custom YAML comments in this file will be lost!
