Yii2-app-skeleton

Yii2-app-skeleton is an Yii2 application template with minimum requirements and dependencies.

Features

• Uses Asset-packagist instead of fxp/composer-asset-plugin to install bower and npm packages.
• Uses PHP dotenv for handling configuration
• Init command which creates needed directories and warms up dotenv config
• Preconfigured multiple cache and session backends which can be switched easily
• No junk you need to remove every time you start (e.g. contact or registration forms as in yiisoft/yii2-app-basic)

Requirements

The minimum requirement by this project template that your Web server supports PHP 5.4.0.

Installation

That's all. After project is created, composer will run php yii init, which will create needed directories and config files. However when you deploy your project to server (or download it using git or zip archive), you will need to run following commands:

Overview

Top level directories

commands

The commands directory contains your console application's controllers (commands).

config

The config directory contains all of your application's configuration files.

controllers

The controllers directory contains your web application's controllers.

mail

The mail directory contains your application's mail view files.

migrations

The migrations directory contains database migration files.

runtime

The runtime directory contains application logs, cache and debug information.

vendor

The vendor directory contains your Composer dependencies.

views

The views directory containes your application's view files.

web

THe web directory contains the index.php file, which is the entry point for all requests entering your application.

Configuration

All of the configuration files are stored in the config directory.

Environment configuration

It is often helpful to have different configuration values based on the environment the application is running in. For example, you may wish to use a different cache driver locally than you do on your production server.

To solve this problem Yii2-app-skeleton uses PHP dotenv. After installation you will find file called .env.example in your config directory. If you install Yii2-app-skeleton via Composer, this file will automatically be renamed to .env. Otherwise, you need to run initialize command.

All of the variables in this file will be loaded into $_ENV PHP super global. You can retrieve them by using env function which is declared inside config/helpers.php file. If you look closer at configuration files in config directory you will see how often function env is used.

Your .env file should not be committed to your application's source control, since each developer / server using your application could require a different environment configuration.

You may want to add custom variables to .env.example file. After you do that, you can run php yii init command and they will be automatically injected in .env file.

Changing application environment

Out of the box Yii2-app-skeleton comes with enabled YII_DEBUG and with YII_ENV="dev". You should change it when deploying your app to production servers (or sometimes you may need it to be done locally on your machine). To do it you can use init/env command:
