How it works?

Step 1

Declare fields you want to retrieve from your LaMetric App you designed, in file config/fields.php.

e.g.

return [
    [
        'key'  => 'field-1',
        'type' => Field::TEXT_TYPE,
    ],
    [
        'key'  => 'field-2',
        'type' => Field::NUMBER_TYPE,
    ],
    [
        'key'  => 'field-3',
        'type' => Field::SWITCH_TYPE,
    ],
    [
        'key'     => 'field-4',
        'type'    => Field::CHOICES_TYPE,
        'choices' => [
            'iron-man',
            'captain-america',
            'ant-man',
            'thor',
        ]
    ]
];

Fields type association with https://developer.lametric.com :

• Field::TEXT_TYPE : Text field
• Field::NUMBER_TYPE : Number
• Field::SWITCH_TYPE : Switch
• Field::CHOICES_TYPE : Single choice

The src/Validator.php object will check parameters sent by the app and manage errors.

You can also add default key to a field. If the value is missing from app request, this valus will be use.

e.g.

return [
    [
        'key'     => 'field-1',
        'type'    => Field::TEXT_TYPE,
        'default' => 'hello'
    ],
];

Step 2

Add you logic to the method fetchData() in src/Api.php. Maybe you need to extract data from an API. You can inject any dependencies as needed.

You can also inject credentials like secret api-key : copy config/credentials.php.dist to config/credentials.php and edit content.

/**
 * object $this->client (Guzzle HTTP) is available to make curl requests
 * array $this->credentials contains sensitive data
 * array $parameters (credentials) can contain sensitive data
 */

Step 3

Adapt the method mapData() in src/Api.php to manage frames and data you need.

More information about frames here.

Step 4 & Hosting

You can deploy it everywhere you want. You only need PHP and ext-json (ext-curl if you consume an API).

You only need to configure the docroot of your vhost to the folder public.
