Fusio is an open source API management platform which helps to build and manage RESTful APIs. We think that there is a huge potential in the API economy. Whether you need an API to expose your business functionality, build micro services, develop SPAs or Mobile-Apps. Because of this we think that Fusio is a great tool to simplify building such APIs. More information on http://www.fusio-project.org/
Fusio covers all important aspects of the API lifecycle so you can concentrate on building the actual business logic of your API.
It is possible to define different versions of your endpoint. A concrete version can be requested through the
Fusio generates automatically a documentation of the API endpoints based on the provided schema definitions.
Fusio uses the standard JSONSchema to validate incoming request data.
Fusio uses OAuth2 for API authorization. Each app can be limited to scopes to request only specific endpoints of the API.
Fusio monitors all API activities and shows them on a dashboard so you always know what is happening with your API.
It is possible to limit the requests to a specific threshold.
Fusio generates different specification formats for the defined API endpoints i.e. OAI (Swagger), RAML.
Fusio provides an API where new users can login or register a new account through GitHub, Google, Facebook or through normal email registration.
All errors which occur in your endpoint are logged and are visible at the backend including all information from the request.
Fusio provides an adapter system to connect to external services. By default we provide the HTTP and SQL connection type but there are many other types available i.e. MongoDB, Amqp, Cassandra.
Fusio has a migration system which allows you to change the database schema on deployment.
Fusio provides an api test case wherewith you can test every endpoint response without setting up a local web server.
Basically with Fusio you only have to define the schema (request/response) of your API endpoints and implement the business logic. All other aspects are covered by Fusio.
Fusio provides two ways to develop an API. The first way is to build API endpoints only through the backend interface by using all available actions. Through this you can solve already many tasks especially through the usage of the v8 action.
The other way is to use the deploy mechanism. Through this you can use normal
PHP files to implement your business logic and thus you have ability to use the
complete PHP ecosystem. Therefor you need to define a
deploy file which specifies the available routes and actions of the system.
This file can be deployed with the following command:
php bin/fusio deploy
The action of each route contains the source which handles the business logic.
This can be i.e. a simple php file, php class or a url. More information in the
src/ folder. In the following an example action to build an API response
from a database:
<?php /** * @var \Fusio\Engine\ConnectorInterface $connector * @var \Fusio\Engine\RequestInterface $request * @var \Fusio\Engine\Response\FactoryInterface $response * @var \Fusio\Engine\ProcessorInterface $processor * @var \Psr\Log\LoggerInterface $logger * @var \Psr\SimpleCache\CacheInterface $cache */ /** @var \Doctrine\DBAL\Connection $connection */ $connection = $connector->getConnection('Default-Connection'); $count = $connection->fetchColumn('SELECT COUNT(*) FROM app_todo'); $entries = $connection->fetchAll('SELECT * FROM app_todo WHERE status = 1 ORDER BY insertDate DESC LIMIT 16'); return $response->build(200, , [ 'totalResults' => $count, 'entry' => $entries, ]);
In the code we get the
Default-Connection which we have defined previously
.fusio.yml deploy file. In this case the connection returns a
\Doctrine\DBAL\Connection instance but we have already many adapters to
connect to different services. Then we simply fire some queries and return the
Fusio provides several apps which work with the internal backend API. These apps can be used to manage and work with the API. This section gives a high level overview what the Fusio system provides and how the application is structured. Lets take a look at the components which are provided by Fusio:
If you install a Fusio system it setups the default API. Through the API it is possible to manage the complete system. Because of that Fusio has some reserved paths which are needed by the system.
Endpoints for the system configuration
Endpoints for the consumer i.e. register new accounts or create new apps
Endpoints for the documentation
Endpoints for the consumer to get i.e. information about the user itself and to revoke an obtained access token
Endpoints to export the documentation into other formats i.e. swagger
The following apps are working with the Fusio API.
The backend app is the app where the administrator can configure the system. The
app is located at
The developer app is designed to quickly setup an API program where new
developers can register and create/manage their apps. The app is located at
The documentation app simply provides an overview of all available endpoints.
It is possible to export the API definition into other schema formats like i.e.
Swagger. The app is located at
