Creating the bundle

While developing our app initially, we didn't care about where our files were. Everything was under a giant monolithic bundle that included everything. We'll go through the following steps to change the situation and make a decoupled GithubAuthBundle:

1. Set up the bundle.

2. Move or write the code.

3. Move or create the services configuration directly in the bundle.

4. Define the bundle configuration and merge the user-defined parameters.

First, we will use the following command line provided by Symfony to generate an empty bundle:

php app/console generate:bundle

To do this, you have to choose a namespace and a bundle name, which in the case of this book are Khepin and GithubAuthBundle. Now, let's move all the required files to this new bundle and update their namespaces accordingly. In the end, our bundle structure should be as follows:

GithubAuthBundle/
    DependencyInjection/
        Configuration.php
        KhepinGithubAuthExtension.php
    Resources/
        config/
          ...
