Installation

You can install the package via composer.

composer require onetechasia/cognito

Next you can publish the config

    php artisan vendor:publish --provider="Onetech\Cognito\Providers\CognitoServiceProvider"

Configure

Add config to environment file: .env

# AWS Cognito configurations
AWS_ACCESS_KEY_ID=""
AWS_SECRET_ACCESS_KEY=""
AWS_COGNITO_CLIENT_ID=""
AWS_COGNITO_CLIENT_SECRET=""
AWS_COGNITO_USER_POOL_ID=""
AWS_COGNITO_REGION="us-east-1"
AWS_COGNITO_VERSION="latest"

Last but not least you want to change the auth driver: config/auth.php

    'guards' => [
        'cognito-token' => [
            'driver' => 'cognito-token', // This line is important for using AWS Cognito as API Driver
            'provider' => 'users',
        ],
    ],

Add to middleware for authentication: app/Http/Kernel.php

    protected $routeMiddleware = [
        'onetech.cognito' => \Onetech\Cognito\Http\Middleware\CognitoAuthenticate::class,
    ];
