This is my package maintenance

This is where your description should go. Limit it to a paragraph or two. Consider adding a small example.

Requirements

Make sure that your server is configured with following PHP version and extensions:

• PHP 8.1+
• Spiral framework 3.0+

Installation

You can install the package via composer:

composer require spiral-packages/maintenance

After package install you need to register bootloader from the package.

protected const LOAD = [
    // ...
    \Spiral\Maintenance\Bootloader\MaintenanceBootloader::class,
];

Note: if you are using spiral-packages/discoverer, you don't need to register bootloader by yourself.

Configuration

By default, the package uses file driver for storing information about maintenance mode. If you have multiple instances of your application you need to use cache driver with storage that will be accessed from all instances.

MAINTENANCE_DRIVER=cache
MAINTENANCE_CACHE_STORAGE=null
MAINTENANCE_CACHE_KEY=maintenance

Usage

Include Spiral\Maintenance\Middleware\PreventRequestInMaintenanceModeMiddleware in your application for routes that should not have access during maintenance mode.

final class RoutesBootloader extends BaseRoutesBootloader
{
    protected function globalMiddleware(): array
    {
        return [
            \Spiral\Maintenance\Middleware\PreventRequestInMaintenanceModeMiddleware::class,
            // ...
        ];
    }
}

To enable maintenance mode, execute the down command:

php app.php down

By default, response code for maintenance mode is 503, but you may set custom response code

php app.php down --status=504

To disable maintenance mode, use the up command:

php app.php up

When your application is in maintenance mode the middleware throws Spiral\Maintenance\Exception\MaintenanceModeHttpException with defined status code.

Spiral Framework allows you to pre-render a maintenance mode view that will be returned to the very beginning of the request cycle. You may pre-render a template of your choice using App\ErrorHandler\ViewRenderer. By default, it looks for a template in a folder app/views/exception/{statusCode}.dark.php

You can create a new view file app/views/exception/503.dark.php:

<extends:layout.base title="[[Maintenance mode]]"/>
<use:element path="embed/links" as="homepage:links"/>

<stack:push name="styles">
    <link rel="stylesheet" href="/styles/welcome.css"/>
</stack:push>

<define:body>
    <div class="wrapper">
        <img src="/images/503.svg" alt="Error 503" width="300px"/>
        <h2>{{ $exception->getMessage() ?? 'Maintenance mode' }}</h2>
    </div>
</define:body>
