• Template structure

Differences from yii2-app-advanced

In contrast to the yii2-app-advanced this template out of the box has:

• Support for .env file
• API application
• Include yii2-tools-yarcode
• Set of docker containers
• Integration with Travis CI
• Pre-installed AdminLTE theme for the backend application

Requirements

The minimum requirement by this project template that your Web server supports PHP 7+.

Installation

Install composer.

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

composer create-project --prefer-dist yarcode/yii2-app-yarcode yarcode 
сd yarcode 
php init 

Copy .env file

cp .env.example .env

Configure .env and apply migrations. Make sure that you are properly configured to connect to the database.

php yii migrate 

The template installation is now complete.

Quality Control

Travis CI

To automatically build and test the application in a template, use Travis CI. The configuration is located in the file .travis.yml in the project's root directory.

In the configuration file added PHP Coding Standards Fixer.

PHP Coding Standards Fixer

This tool allows us to automatically check the project code for compliance with standards and rules.

The configuration is in the file .php_cs in the project's root directory.

Execute the command to verify the code for compliance with the PSR-2 standard

vendor/bin/php-cs-fixer fix -v --dry-run 

Vrutalization

This template supports Docker technology

Base usage

Build your containers

docker-compose build

Create volume

docker volume create --name=yiidock_postgres_data

Init and apply migration:

cp docker-compose.override-example.yml docker-compose.override.yml
docker-compose run --rm workspace composer install
docker-compose run --rm workspace php init
docker-compose run --rm yii migrate

Start the containers:

docker-compose up -d

Now app must be working:

• frontend app: http://localhost:8001
• backend app: http://localhost:8002
• api app: http://localhost:8003

You can also start the services individually. Example, start only backend:

docker-compose up -d nginx-backend 

Test environment

Tests are in the test catalogs {application}/tests. They are developed with Codeception PHP Testing Framework. By default there are 2 test suites for each applications(api, frontend, backend):

• unit
• functional

For more information about testing Yii2 applications, read here

To run tests in a container can be used docker-compose.test.yml file. Follow these three simple steps:

1. Create test volume: docker volume create --name=test_postgres_data
2. Apply migration for test database: docker-compose -f docker-compose.test.yml run --rm yii_test migrate
3. Run all the tests that are in the template: docker-compose -f docker-compose.test.yml run --rm codeception run

It is possible to run only unit or only functional tests for the application, for example

docker-compose -f docker-compose.test.yml run --rm codeception run unit -c backend 
docker-compose -f docker-compose.test.yml run --rm codeception run functional -c api 

Also you can run some specific test by specifying the path to it

docker-compose -f docker-compose.test.yml run --rm codeception run functional -c api v1/ApiCest 

For debugging, it can be convenient to run tests with the flags -f and--debug

docker-compose -f docker-compose.test.yml run --rm codeception run functional -c api v1/ApiCest -f --debug
