Configuration Reference

Bootstrap Configuration

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

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.

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.

Possible Values

An absolute or relative file path (string)

Default Value

<unset>

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.

Possible Values

false or <unset>

Default Value

<unset>

Runtime Configuration

General runtime configuration is controlled by the app config located at app/config/app.php. These options control core application functionality.

It is highly recommended to set these values via their respective environment variables. This can be accomplished via a .env file located in the root of your application. An example file is provided as .env.example.
