Yii 2 Skeleton

Yii 2 Skeleton is a new approach to a design skeleton using Yii 2 as a basis.

The motivation to make this new template was to try to organize the packages inside a src directory, keeping all the class there, ie a place where the main application code will be.

REQUIREMENTS

The minimum requirement by this project template that your Web server supports PHP 8+.

RESOURCES

• Nginx + PHP 8.1 with Docker using Webdevops Images
• PHP Unit 9.5
• Yii2 Bootstrap 5 Extension
• PHP Codesniffer 3.5
• PHP Codesniffer Fixer 3

INSTALLATION

Install via Composer

If you do not have Composer, you may install it by following the instructions at getcomposer.org.

You can then install this project template using the following command:

php composer.phar create-project dersonsena/yii2-skeleton skeleton

Your Enviroments Variables

Make a copy of the .env.sample file, you can use cp .env.sample .env in your terminal to do that.

You can place your environment settings in .env file, as below (note the sample file is ready to basic usage):

# ---------
# Docker
# ---------
PROJECT_NAME=yii2-skeleton
DOCKER_APP_PORT=8080
DOCKER_APP_SSL_PORT=443
DOCKER_MYSQL_PORT=3306
XDEBUG_REMOTE_PORT=9000

# ---------
# Application
# ---------
YII_ENV=dev
YII_DEBUG=true
REQUEST_COOKIE_VALIDATION_KEY=YOUR_VALIDATION_KEY
ADMIN_PASSWORD=
# APP_TIMEZONE=America/Sao_Paulo
# APP_LANGUAGE=pt_BR
APP_BASE_URL=http://localhost:8088

# ---------
# Database
# ---------
DB_HOST=your-db-host
DB_USERNAME=root
DB_PASSWORD=secret
DB_DATABASE=your-db-name
DB_DATABASE_TEST=your-test-db-name
DB_SCHEMA_CACHE_DURATION=60

# ---------
# Mailer
# ---------
SMTP_HOST=
SMTP_PORT=465
SMTP_USERNAME=
SMTP_PASSWORD=
SMTP_ENCRYPTION=ssl

NOTE: the commented environment variables are optional and your values set here is its default value.

Run your Application

Before anything change PROJECT_NAME env variable to your project name/alias. This one it will be used to prefixed the application containers and other stuff.

To start your application and start up your containers just run the follow command:

make run

The command above will start 2 docker containers: yii2-skeleton-app (Nginx + PHP 8.1) and yii2-skeleton-db (MySQL)

If you have set a DOCKER_APP_PORT environment variable to 8000, you will can then access the yout application through the following URL:

http://localhost:8000

COHESIVE CONTROLLER

Trying to follow the best programming practices, this boilerplate has a controller type called CohesiveController to help you a create a controller class with a single action (aka handle() method) and a single responsibility.

To create a cohesive controller got to config/routes.php and add your route such as:

<?php

return [
    // other routes...

    'specific/route/to/cohesive/a/controller' => 'cohesive-xpto-routine'
];

The next step is create your CohesiveXptoRoutineController class extending from App\Core\Controller\CohesiveController and implement the handle() method, as below:

<?php

namespace App\Controllers;

use App\Core\Controller\CohesiveController;

class CohesiveXptoRoutineController extends CohesiveController
{
    public function handle()
    {
        // your cohesive and specific implementation here =)
    }
}

Finally, access your Cohesive action: http://localhost:8080/specific/route/to/cohesive/a/controller

THE USEFUL MAKEFILE

The makefile file has several commands to help with day-to-day work. In it you can execute commands inside the container by typing a few letters in your terminal.

If you wanted to install or update the dependencies of your application, you should do something like:

docker exec -it YOUR_CONTAINER_NAME composer install -o

For you not to have to write all this, use make:

make install

Thanks @wilcorrea for showing me this simple yet useful approach.

The makefile of skeleton comes with the following commands:

• install
  

  Perform composer install with optimize autoloaders parameter
  ex.: make install

• require
  

  Perform composer require with the PACKAGE parameter
  ex.: make PACKAGE="vendor/package" require

• dump
  

  Run composer command dump-autoload
  ex.: make dump

• migrate
  

  Alias to execute yii migrate in app container and run all migrations that are not applied
  ex.: make migrate

• migrate-create
  

  Create a new migration in the project
  ex.: make NAME="my-cute-migration" migrate-create

• migrate-down
  

  Rollback the last migration
  ex.: make migrate-down

• cache-clear
  

  Just run the yii cache/flush-all into app container
  ex.: make cache-clear

• db-backup
  

  Generate a backup.sql in the project root dir with a hot backup
  e.: make db-backup

• db-restore
  

  Import a backup.sql that are in the project root dir to database container
  e.: make db-restore
