Amazon alexa symfony bundle

This bundle is a simple helper to create an Amazon Echo (Alexa) endpoint to your symfony project. You only need to add the Bundle to your project and create some handlers for the alexa requests, configured in amazon alexa backend.

Requirements

• PHP 8.2+
• Symfony 6.4+

Install via composer

Require the bundle via composer:

composer require maxbeckers/amazon-alexa-bundle

Enable the Bundle

Add the bundle to your config/bundles.php:

return [
    // ...existing bundles...
    MaxBeckers\AmazonAlexaBundle\MaxBeckersAmazonAlexaBundle::class => ['all' => true],
];

Enable Routing

Then add the Bundle endpoint for alexa to config/routes.yaml.

# config/routes.yaml
maxbeckers_amazon_alexa:
    path: /alexa/
    controller: MaxBeckers\AmazonAlexaBundle\Controller\AmazonAlexaController::amazonRequestAction

Create handlers

To add Handlers for alexa, create them as a service and tag them with maxbeckers_amazon_alexa.request_handler. How to create a handler see maxbeckers/amazon-alexa-php.

# config/services.yaml
services:
    Example\MyIntentHandler:
        arguments:
            - '@MaxBeckers\AmazonAlexa\Helper\ResponseHelper'
        tags:
            - 'maxbeckers_amazon_alexa.request_handler'

Generate ssml

For ssml use the MaxBeckers\AmazonAlexa\Helper\SsmlGenerator service to create valid ssml.

use MaxBeckers\AmazonAlexa\Helper\SsmlGenerator;

class MyService
{
    public function __construct(
        private readonly SsmlGenerator $ssmlGenerator
    ) {
    }

    public function generateSsml(): string
    {
        // add a message
        $this->ssmlGenerator->say('Hello World');
        $ssml = $this->ssmlGenerator->getSsml();
        // $ssml === '<speak>Hello World</speak>'
        
        return $ssml;
    }
}

For backward compatibility, you can still use the service ID:

$ssmlGenerator = $this->container->get('maxbeckers_amazon_alexa.ssml_generator');
