Navitia Component

Navitia Component is a PHP library to query Navitia Api (https://api.navitia.io), and controls query parameters.

Requirements

• PHP: >=7.4
• a Navitia token

Note: If you don't have a Navitia token yet, you have to register here: https://navitia.io/register

Choose your version

• NavitiaComponent v1.x.x used by legacy projects in production (example NMM Realtime)

• NavitiaComponent v2.x.x compatible with frameworks like Symfony4

• NavitiaComponent v3.0.0 compatible with modern frameworks like Symfony5.4, with old firm name CanalTP

• NavitiaComponent v3.1.x compatible with modern frameworks like Symfony5.4, with present firm name Hove

Installation

Using composer:

composer require "hove/navitia":"^3.1"

example for previous versions (before v3.1.x, deprecated)

composer require "canaltp/navitia":"~2.0"

How to use NavitiaComponent ?

By autowire

In services.yaml file of your app, add this :

    navitia_component:
        class: Navitia\Component\Service\ServiceFacade
        factory: [Navitia\Component\Service\ServiceFacade, getInstance]
        calls:
            - [ setCache, ["@cache.app.taggable"]]
            - [ setConfiguration, ["%navitia_config%"]]

And then add @navitia_component to the service that used NavitiaComponent like this :

    App\Service\Navitia:
        class: App\Service\Navitia
        arguments: ['@navitia_component']

Set configuration:

You can pass an array of config with the setConfiguration function.

namespace App\Service;

use Navitia\Component\Service\ServiceFacade;

class Navitia
{
    private ServiceFacade $navitiacomponent;

    function __construct(ServiceFacade $navitiacomponent)
    {
        $this->navitiacomponent = $navitiacomponent;
        // Configuration
        $config = array(
            'url' => 'api.navitia.io',
            'token' => '3b036afe-4242-abcd-4242-99718476c2e0', // Example of token
        );
        $this->navitiacomponent->setConfiguration($config);
    }
}

Query example:

$query = array(
    'api' => 'journeys',
    'parameters' => array(
        'from' => '2.3749036;48.8467927',
        'to' => '2.2922926;48.8583736',
    ),
);

$result = $this->navitiacomponent->call($query); // Returns an object with Api result

Config parameters:

Uses cases

Navitia component supports these apis:

• Journeys
• Coverage
• Departures

Journeys

Example of an itinerary:

$query = array(
    'api' => 'journeys',
    'parameters' => array(
        'from' => '2.3749036;48.8467927',
        'to' => '2.2922926;48.8583736',
    ),
);

$result = $this->navitiacomponent->call($query);

Coverage

Example, retrieve metadata about a coverage:

$query = array(
    'api' => 'coverage',
    'parameters' => array(
        'region' => 'sandbox',
    ),
);

$result = $this->navitiacomponent->call($query);

See also: http://doc.navitia.io/#coverage

Departures

Example, get all next departures of a line and at a datetime:

$query = array(
    'api' => 'departures',
    'parameters' => array(
        'region' => 'sandbox',
        'path_filter' => '/lines/line:RAT:M1/departures?from_datetime=20160615T1337'
    ),
);

$result = $this->navitiacomponent->call($query);

See also: http://doc.navitia.io/#departures

Calling any other Api

To query Navitia with any other url using this component and the config you have provided, this pattern do the trick:

$query = array(
    'api' => 'coverage',
    'parameters' => array(
        'region' => 'sandbox',                          // Coverage name
        'path_filter' => 'stop_areas?variable=value',   // Url to call
    ),
);

$result = $this->navitiacomponent->call($query);
// Will call http://api.navitia.io/v1/coverage/sandbox/stop_areas?variable=value

Using query builder

You can use a query builder:

use Navitia\Component\Request\JourneysRequest;
use Navitia\Component\Request\Parameters\JourneysParameters;

$query = new JourneysRequest();

$actionParameters = new JourneysParameters();

$actionParameters
    ->setFrom('2.3749036;48.8467927')
    ->setTo('2.2922926;48.8583736')
    ->setDatetime('20160819T153000')
;

$query->setParameters($actionParameters);

$result = $this->navitiacomponent->call($query);

Using query builder to get all next departures:

use Navitia\Component\Request\Parameters\CoverageDeparturesParameters;
use Navitia\Component\Request\DeparturesRequest;

$query = new DeparturesRequest();
$query->setRegion('sandbox')->setPathFilter('lines/line:RAT:M1');

$actionParameters = new CoverageDeparturesParameters();
$actionParameters->setDuration(1);
$actionParameters->setFromDatetime('20160615T1337');
$actionParameters->setForbiddenUris(['lines', 'modes']);
$actionParameters->setDataFreshness('realtime');

$query->setParameters($actionParameters);

$result = $this->navitiacomponent->call($query);

Running Tests

For this part, you should use docker (need install) and launch it with :

make all_tests_dev
