yii2-app-template Yii 2 Application Template with ConfigKit

This is the proposed application boilerplate template by 2amigOS! for your Yii 2 applications.

The application comes with the configuration tooling named ConfigKit that we use to fire up our applications. With the kit you will be able to create your very own project structure template boilerplate, your very own customized way of using Yii.

The structure is pretty straight-forward and its files provide clear documentation of what is happening on each step. For example, this is the web app bootstrap file:

use SideKit\Config\ConfigKit;
use yii\web\Application;

 * --------------------------------------------------------------------------
 * Create Yii web application
 * --------------------------------------------------------------------------
 * Grab the configuration for the 'web' application and initialize an
 * Application instance with it. Remember that the file 'sidekit.php' has to
 * be *required* prior inserting this script so we can access the environment
 * variables.

$config = ConfigKit::config()->build('web', ConfigKit::env()->get('CONFIG_USE_CACHE'));
$app = new Application($config);

 * --------------------------------------------------------------------------
 * Return application
 * --------------------------------------------------------------------------
 * Return instance to calling script, that way we separate initialization
 * processes and liberate the entry script with too much code.

return $app;

Here is an brief explanation of the structure:

app                 [ Yii's application related code: commands, components, controllers, bundles, models, modules, 
|                     views and widgets ]
├── assets          [ contains asset's definitions ]
├── commands        [ contains Console commands (Yii names them controllers) ]
├── controllers     [ contains Web controller classes ]
├── models          [ contains model calsses ]
└── views           [ contains view files for the Web application ]
bin                 [ contains command-line executable scripts ]
bootstrap           [ contains bootstrap process files ]
config              [ contains application configuration files ]
public              [ contains Web application entry script + static resources ]
runtime             [ contains files generated during application's runtime ]
src                 [ contains domain business logic files. Portable code, free of Yii's code. Build your library here. ]
tests               [ contains codeception tests for your application ]

As you can see, the structure includes a src folder and you may wonder, why is that folder there if we follow the MVC pattern? Why does it says that we should include domain business logic there? And you probably thinking the same with that gulpfile.js, if Yii handles all that, why that file exists?

You can do whatever you want, in fact, every developer has its own way to do things and Yii is a great framework with an amazing flexibility to please every taste that is not a php-purist. But, if you are a developer who likes to listen from other people's experiences and you think your application is going to escalate to another dimension, please take this important advice:

  • DO NOT include your business logic in your models and/or controllers. Keep your models thin and your controllers even thinner.

Create your business logic following D.R.Y. and S.O.L.I.D. whenever possible on that src folder. Add your custom namespaces to composer.json file and use the amazing Yii's container with composer autoloader super-powers, is awesome, really.

If you application grows, you will be happy to see how portable your code is; that you don't need to dig in your models, controllers and even views (yes, I have seen that too with widgets). Failing to do that, you will end up in a bottleneck where all possible changes to the core of your app will be highly expensive.
