Dependency injection

Fusio uses internally the Symfony DependencyInjection Component to manage all services. To register a service you need take a look at the resources/container.php file. This file describes all services and how to load them.

<?php

use Fusio\Engine\Adapter\ServiceBuilder;
use PSX\Framework\Dependency\Configurator;
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $container) {
    $services = ServiceBuilder::build($container);
    $services = Configurator::services($services);

    $services->load('App\\Action\\', __DIR__ . '/../src/Action');
    $services->load('App\\Connection\\', __DIR__ . '/../src/Connection');

    $services->load('App\\Service\\', __DIR__ . '/../src/Service')
        ->public();

    $services->load('App\\Table\\', __DIR__ . '/../src/Table')
        ->exclude('Generated')
        ->public();

    $services->load('App\\View\\', __DIR__ . '/../src/View');
};

Folders​

The following folders are auto-wired by the DI container, we recommend to use those standard folders but you are of course free to structure the folders how you like.

Action​

The action folder contains action classes which either extend from Fusio\Engine\ActionAbstract or Fusio\Engine\ActionInterface. An action contains the business logic and i.e. invokes another endpoints or fetches data from a database. You can then reference those classes either directly in an operations yaml file or you can select action at the backend.

Connection​

The connection folder contains connection classes which either extend from Fusio\Engine\ConnectionAbstract or Fusio\Engine\ConnectionInterface. A connection provides a connection to a remote system i.e. it could return an connection to a database or also a client SDK. Connections can be used in your action to complete a specific task.

Service​

A service is a general PHP class which contains business logic independent of the Fusio context. In general the service should contain the logic to create, update or delete a specific entity.

Table​

The table folder contains table classes which are automatically generated from your schema. By default Fusio only works with a migration system where you define the table structure, then you can use the following command to generate all tables s.

php bin/fusio generate:table

Fusio does not come with an ORM system by default but you are of course free to include any ORM you like.

View​

View classes are also classes to produce a specific view i.e. a collection or entity response. Those classes do not work on a concrete table but they can use the table classes to create a fitting response.

Debug​

To debug the container and see all available services you can use the following command s.

php bin/fusio debug:container
