Configuration Reference

Bootstrap Configuration

These configuration options are special configuration options only configurable through environment variables (e.g. through the .env file).

{% hint style="info" %} There are no corresponding configuration options for these values in the app/config definitions because they are applied before the application container (and configuration) is loaded. {% endhint %}

`FILES_PATH`

A path (relative or absolute) to the directory in which you would like to list. This may even be a path outside of the application directory. When left unset, the root application directory (i.e. the folder where index.php is located) will be listed.

{% tabs %} {% tab title="Possible Values" %} An absolute or relative file path (string) {% endtab %}

{% tab title="Default Value" %} <unset> {% endtab %} {% endtabs %}

`COMPILE_CONTAINER`

Whether or not the application container will be compiled. When set to false the container will not be compiled and cached. If left unset the container will be compiled and cached on first run and the cached container will be reused on subsequent requests. Disabling this comes with a (likely negligible) performance hit. Generally this should not be changed but might be necessary to modify when running Directory Lister on a read-only filesystem.

{% tabs %} {% tab title="Possible Values" %} false or <unset> {% endtab %}

{% tab title="Default Value" %} <unset> {% endtab %} {% endtabs %}

Runtime Configuration

General application runtime configuration can be controlled through environment variables. This can be accomplished via an .env file located in the root of your application. An example file is provided as .env.example.

{% hint style="info" %} Advanced configuration can be accomplished via the app config located at app/config/app.php. However, changes to this fill will need to be manually re-applied between upgrades. It is highly recommended to stick to environment variables for controlling app configuration unless absolutely necessary. {% endhint %}

`APP_DEBUG`

Enable application debugging and display error messages.

{% hint style="danger" %} It is recommended that debug remains OFF unless troubleshooting an issue. Leaving this enabled WILL cause leakage of sensitive server information. {% endhint %}

{% tabs %} {% tab title="Possible Values" %} true or false {% endtab %}

{% tab title="Default Value" %} false {% endtab %} {% endtabs %}

`APP_LANGUAGE`

{% tab title="Default Value" %} Y-m-d H:i:s {% endtab %} {% endtabs %}

`DIRECT_LINKS`

Cache Configuration

Application cache configuration is also controlled through environment variables. This can be accomplished via an .env file located in the root of your application. An example file is provided as .env.example.

However, changes to this fill will need to be manually re-applied between upgrades. It is highly recommended to stick to environment variables for controlling cache configuration unless absolutely necessary. {% endhint %}

]

{% endtab %} {% endtabs %}

`memcached_config`

The Memcached configuration anonymous function (closure). This option is used when the cache_driver configuration option is set to memcached. The closure receives a Memcached object as it's only parameter. You can use this object to configure the Memcached connection. At a minimum you must connect to one or more Memcached servers via the addServer() or addServers() methods.

{% hint style="info" %} Reference the PHP Memcached documentation for Memcached configuration options. {% endhint %}

{% tabs %} {% tab title="Possible Values" %} An anonymous function that receives a Memcached object

function (Memcached $memcached): void {
    // Configure the $memcached object
}

{% tab title="Default Value" %}

DI\value(function (Memcached $memcached, Config $config): void {
    $memcached->addServer(
        $config->get('memcached_host'),
        $config->get('memcached_port')
    );
})

This closure adds a single connection to a server at the host defined by memcached_host on the port defined by memcached_port. {% endtab %}

{% tab title="Environment Variables" %} Uses the MEMCACHED_HOST and MEMCACHED_PORT variables by default {% endtab %} {% endtabs %}

`redis_config`

The Redis configuration anonymous function (closure). This option is used when the cache_driver configuration option is set to redis. The closure receives a Redis object as it's only parameter. You can use this object to configure the Redis connection. At a minimum you must connect to one or more Redis servers via the connect() or pconnect() methods.

{% hint style="info" %} Reference the phpredis documentation for Redis configuration options. {% endhint %}

{% tabs %} {% tab title="Possible Values" %} An anonymous function that receives a Redis object

function (Redis $redis): void {
    // Configure the $redis object
}

{% endtab %}

{% tab title="Default Value" %}

DI\value(function (Redis $redis, Config $config): void {
    $redis->pconnect(
        $config->get('redis_host'),
        $config->get('redis_port')
    );
})

This closure adds a single connection to a server at the host defined by redis_host on the port defined by redis_port. {% endtab %}

{% tab title="Environment Variables" %} Uses the REDIS_HOST and REDIS_PORT variables by default {% endtab %} {% endtabs %}

`http_cache`

HTTP cache values for controlling browser page cache duration. An array of mime types mapped to their cache duration in seconds.

{% tabs %} {% tab title="Possible Values" %} An array of mime types mapped to their cache duration as a seconds (integers). {% endtab %}

{% tab title="Defualt Value" %}

[
    'application/json' => 300,
    'application/zip' => 300,
]

{% endtab %} {% endtabs %}

`sort_order`

An anonymous function can be used to customize the sort order of files and folders in your directory listing. The anonymous function receives two SplFileInfo objects as arguments and must return an integer less than, equal to, or greater than zero to represent the first argument being respectively less than, equal to, or greater than the second.

'sort_order' => \DI\value(
    function (SplFileInfo $file1, SplFileInfo $file2): int {
        return strcmp($file1->getRealPath(), $file2->getRealPath());
    })
);

{% hint style="warning" %} The anonymous function must be wrapped in a \DI\value() function. {% endhint %}
