Symfony Standard DDD Edition

Welcome to the Symfony Standard DDD Edition - a fully-functional Symfony application with DDD architecture that you can use as the skeleton for your new applications.

For details on how to download and get started with Symfony, see the Installation chapter of the Symfony Documentation.

Installing the Symfony Standard DDD Edition

When it comes to installing the Symfony Standard DDD Edition, you have the following options.

Use Composer (recommended)

As Symfony uses Composer to manage its dependencies, the recommended wayto create a new project is to use it.

If you don't have Composer yet, download it following the instructions on http://getcomposer.org/ or just run the following command:

curl -s http://getcomposer.org/installer | php

Then, use the create-project command to generate a new Symfony application:

php composer.phar create-project regniblod/symfony-ddd-edition --stability=dev path/to/install

Composer will install Symfony and all its dependencies under the path/to/install directory.

Download an Archive File

To quickly test Symfony, you can also download an archive of the Standard DDD Edition and unpack it somewhere under your web server root directory.

If you downloaded an archive "without vendors", you also need to install all the necessary dependencies. Download composer (see above) and run the following command:

php composer.phar install

Checking your System Configuration

Before starting coding, make sure that your local system is properly configured for Symfony.

Execute the check.php script from the command line:

php bin/symfony_requirements

Access the config.php script from a browser:

http://localhost/path/to/symfony/config.php

If you get any warnings or recommendations, fix them before moving on.

Getting started with Symfony

This distribution is meant to be the starting point for your Symfony applications.

A great way to start learning Symfony is via the Quick Tour, which will take you through all the basic features of Symfony2.

Once you're feeling good, you can move onto reading the official Symfony2 book.

A default bundle, ModuleBundle, shows you Symfony DDD architecture in action. After playing with it, you can remove it by following these steps:

• remove the routing entries referencing ModuleBundle in app/config/routing.yml.
• remove the ModuleBundle from the registered bundles in app/AppKernel.php.
• remove src/Project/Module and tests/Project/Module directories.
• Remove all the .gitkeep files: find . -name .git -prune -o -type d -empty -exec touch {}/.gitkeep \;

How to add a new module

Use the command symfony-ddd:generator:create-module <module_name> to create a new module with the complete src and tests directory structure, bundle, services and repositories files, routing and Doctrine mapping.

What's inside?

The Symfony Standard DDD Edition is configured with the following defaults:

• A ModuleBundle you can use to start coding.
