Google App Engine (GAE) Standard Environment support package for Laravel 9.x.

Based on original work for App Engine Standard (on the PHP5.5 runtime) by @shpasser https://github.com/shpasser/GaeSupportL5

Note: we only intend to support Laravel LTS releases, with this version targeted specifically at Laravel 9.x

Functionality

• StackDriver Logging integration
• StackDriver Trace integration (see docs/trace.md)
• Blade View Pre-Compiler (optional, see docs/blade-pre-compile.md)
• Guzzle integration (optional, see docs/trace.md)
• Laravel Auth Integration for IAP (optional, see docs/iap-auth-verify.md)
• Queue Driver for Cloud Tasks (optional, see docs/queue.md)
• Examples for deployment from Git via Cloud Build, plus encrypted secrets with KMS (optional, see docs/cloudbuild.md)

Installation

Pull in the package via Composer:

"require": {
    "a1comms/gae-support-laravel": "~9.0"
}

Laravel Specific (Not Lumen)

1. Add the following to composer.json:

    "scripts": {
        "post-autoload-dump": [
            "php artisan gae:prepare"
        ]
    },

2. For Laravel, include the service provider within config/app.php:

    'providers' => [
        A1comms\GaeSupportLaravel\GaeSupportServiceProvider::class,
    ];

3. Also, for added functionality, include the optional service providers:

    'providers' => [
        A1comms\GaeSupportLaravel\Auth\AuthServiceProvider::class,
        A1comms\GaeSupportLaravel\View\ViewServiceProvider::class,
        A1comms\GaeSupportLaravel\Queue\QueueServiceProvider::class,
        A1comms\GaeSupportLaravel\Trace\TraceServiceProvider::class,
    ];

And remove the relevant Laravel service providers that these replace:

    'providers' => [
        //Illuminate\View\ViewServiceProvider::class,
        //Illuminate\Queue\QueueServiceProvider::class,
    ];

4. Update bootstrap/app.php to load the overridden application class & initialise logging to Stackdriver:

/*
|--------------------------------------------------------------------------
| Create The Application
|--------------------------------------------------------------------------
|
| The first thing we will do is create a new Laravel application instance
| which serves as the "glue" for all the components of Laravel, and is
| the IoC container for the system binding all of the various parts.
|
*/

$app = new A1comms\GaeSupportLaravel\Foundation\Application(
    $_ENV['APP_BASE_PATH'] ?? dirname(__DIR__)
);

5. Update app/Exceptions/Handler.php to enable proper Exception logging to StackDriver Error Reporting & Logging:

Change the following use statement:

use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;

To our class, that'll inject the required logging hook:

use A1comms\GaeSupportLaravel\Foundation\Exceptions\Handler as ExceptionHandler;

6. In config/logging.php, configure a custom logger and set it as the default:

It's also useful to set the emergency log path to a location App Engine will forward to Stackdriver Logging, see below.

<?php

use A1comms\GaeSupportLaravel\Log\CreateLoggingDriver;

return [
    
    'default' => 'gae',

    'channels' => [
        'gae' => [
            'driver' => 'custom',
            'via' => CreateLoggingDriver::class,
        ],

        'emergency' => [
            'path' => '/var/log/emergency.log',
        ],
    ],

];

7. In .env, set the following:

QUEUE_CONNECTION=gae
CACHE_DRIVER=array
SESSION_DRIVER=gae
LOG_CHANNEL=gae

Lumen Specific (Not Laravel)

1. Update bootstrap/app.php to load the overridden application class

/*
|--------------------------------------------------------------------------
| Create The Application
|--------------------------------------------------------------------------
|
| Here we will load the environment and create the application instance
| that serves as the central piece of this framework. We'll use this
| application as an "IoC" container and router for this framework.
|
*/

$app = new A1comms\GaeSupportLaravel\Foundation\LumenApplication(
    $_ENV['APP_BASE_PATH'] ?? dirname(__DIR__)
);

2. Update app/Exceptions/Handler.php to enable proper Exception logging to StackDriver Error Reporting & Logging:

Change the following use statement:

use Laravel\Lumen\Exceptions\Handler as ExceptionHandler;

To our class, that'll inject the required logging hook:

use A1comms\GaeSupportLaravel\Foundation\Exceptions\LumenHandler as ExceptionHandler;
