Framework Installation

EasySwoole utilizes Composer to manage its dependencies. Before starting the installation process, please ensure that you have got your system satisfied with our requirements, and Composer installed on your machine. During the installation process, the framework files will be downloaded to the project root directory automatically, please make sure the folder is writable.

Install via Composer

Follow the steps below to install manually

composer require easyswoole/easyswoole=3.x
php vendor/bin/easyswoole install

If the installation encounters an error, please see the error handling below

Reporting Error Handling

In some cases, especially those PHP integrated server environment such as wamp/xampp/mamp, you might see the following error message appear:

dir=$(d=${0%[/\\]*}; cd "$d" > /dev/null; cd '../easyswoole/easyswoole/bin' && pwd)

# See if we are running in Cygwin by checking for cygpath program
if command -v 'cygpath' >/dev/null 2>&1; then
    # Cygwin paths start with /cygdrive/ which will break windows PHP,
    # so we need to translate the dir path to windows format.
    # we could be using cygwin PHP which does not require this, so we
    # test if the path to PHP starts with /cygdrive/ rather than /usr/bin
    if [[ $(which php) == /cygdrive/* ]]; then
        Dir=$(cygpath -m "$dir");
    fi
fi

dir=$(echo $dir | sed 's/ /\ /g')
"${dir}/easyswoole" "$@"

The most likely reason could be the symlink function is disabled in the PHP.ini file, or can't create a symbolic link in the vendor directory. You can execute the following command line to confirm whether the symlink function is disabled or not. If it was, there should no symlink in the output list

php -ini | grep disable_functions

If the function is disabled, you can directly modify PHP.ini or enable the function in the admin panel, delete the vendor directory in the project directory, and re-run composer install command to pull the dependency package once again.

If the error is caused by other reasons, you can manually execute the following command in the project root directory to link the executable file:

cd vendor/bin/ && rm -rf easyswoole && ln -s ../easyswoole/easyswoole/bin/easyswoole easyswoole && cd ../../

Or directly point to the EasySwoole management script to execute the install command:

php vendor/easyswoole/easyswoole/bin/easyswoole install

Manual Installation

Follow the steps below to manually install

composer require easyswoole/easyswoole=3.x-dev
php vendor/bin/easyswoole install

If there is no error appears during the installation, then:

# Fire-up the framework
php easyswoole start

If the fire-up action failed, please refer to the error message.

Now if you could see the welcome page by visiting http://localhost:9501, congratulations, EasySwoole has been installed and good to go!

Hello World

Create the following directory structure in the project root directory.

project - The project root directory
----------------------------------
├─App               - App directory
│ └─HttpController  - the controller directory of the application
│   └─Index.php     - default controller file
----------------------------------

The App directory is the central place where you should put all business logic. Modify the Index.php file to add some codes as below:

<?php
namespace App\HttpController;
use EasySwoole\Http\AbstractInterface\Controller;

class Index extends Controller
{

    function index()
    {
        // TODO: Implement index() method.
        $this->response()->write('Hello World');
    }
}

Then update the composer.json file in the root directory to register the application's namespace.

{
    "autoload": {
        "psr-4": {
            "App\\": "App/"
        }
    },
    "require": {
        "easyswoole/easyswoole": "3.x-dev"
    }
}

In fact, the namespace App is registered

At last, run composer dumpautoload command in the prompt. The framework now can automatically load the files in the App directory, so you can start writing the business logic at this stage.

# update namespace mapping
composer dumpautoload
# start framework
php easyswoole start

After the application launched, you should see Hello World by visiting http://localhost:9501.

About IDE Assistant

Since Swoole extension is not included in default PHP installation packages, so the IDE which you're using, might not perform automatic completion. In order to avoid the tips of undefined and improve work efficiency, we recommend you install the Swoole IDE Helper by:

composer require easyswoole/swoole-ide-helper

Directory Structure

EasySwoole can support very flexible files/directories structure, almost it can be customized without any constraints, but we still recommended you to use the directory structure below:

Project                     - project root directory
├─App                       - application directory (can have more than one)
│ ├─HttpController          - controllers directory
│ │ └─Index.php             - default controller
│ └─Model                   - models directory
├─Log                       - log files directory
├─Temp                      - temporary files directory
├─vendor                    - third-party library directory
├─composer.json             - composer.json
├─composer.lock             - composer.lock
├─EasySwooleEvent.php       - framework global event
├─easyswoole                - framework management script
├─easyswoole.install        - framework installation lock file
├─dev.php                   - development environment configuration file
├─produce.php               - production environment configuration file

If you want to use some static resource files (Such as images, css, js, etc.) in your project, it is recommended to use Nginx / Apache as the tier-1 server, then forward the request to EasySwoole for processing. Meanwhile using a separated Public directory as the root of web server.

Note! You shall never ever use the framework root directory as the root directory of the web server, which is going to make the dev.php/produce.php accessible.
