Typed Config Resolver for Laravel

Do you use Laravel and fight the mixed signatures of config() when performing static analysis?

Smpita/ConfigAs types your config calls for you.

This package wraps Smpita/TypeAs, a generalized PHP library useful on any PHP project employing static analysis or tight type enforcement.

Installation

You can install the package via composer:

composer require smpita/configas

Usage

Please see SIGNATURES for the list of current methods and signatures.

General Usage

SIGNATURES#resolving

Pass a key and it will throw a ConfigAsResolutionException if the key isn't of the given type.

use Smpita\ConfigAs\ConfigAs;

$typed = ConfigAs::int('config.key');

If you want to suppress throwing exceptions, provide a default.

use Smpita\ConfigAs\ConfigAs;

$typed = ConfigAs::int('config.key', 123);

The Class Method

SIGNATURES#class

class() has a slightly different signature because you need to specify the class you are expecting.

use Smpita\ConfigAs\ConfigAs;

$typed = ConfigAs::class(Target::class, 'config.key');

You can still provide a default.

use Smpita\ConfigAs\ConfigAs;

$typed = ConfigAs::class(Target::class, 'config.key', new Target('default'));

Nullables

If you would prefer to receive null instead of having an exception thrown, each type method has a nullable counterpart.

use Smpita\ConfigAs\ConfigAs;

ConfigAs::nullableString('config.key') === null; // true

Cache

SIGNATURES#cache

To keep things performant, types are only validated once and results are cached in static arrays for the lifetime of the request. To guarantee a fresh value, you may use the fresh methods that are available for each type.

use Smpita\ConfigAs\ConfigAs;

$typed = ConfigAs::freshString('config.key');

Forgetting

SIGNATURES#forgetting

For each type, you can forget any given cached value.

use Smpita\ConfigAs\ConfigAs;

ConfigAs::forgetFloat('config.key');

You can flush the cache of a type.

use Smpita\ConfigAs\ConfigAs;

ConfigAs::flushFloats();

You can flush all keys.

use Smpita\ConfigAs\ConfigAs;

ConfigAs::flush();

Resolvers

SIGNATURES#resolver-registration

You can leverage the included Smpita\TypeAs library to create your own custom resolvers. For creation, global registration, and full instructions, see the library docs.

Single use

$typed = Smpita\ConfigAs::string('config.key', null, new CustomStringResolver);

Helpers

SIGNATURES#helpers

There is a configAs() helper method located in the Smpita\ConfigAs namespace.

use function Smpita\ConfigAs\configAs;

$configAs = configAs();

$string = $configAs->string('config.string.key');
$array = $configAs->array('config.array.key');

Resolver methods have an associated helper method located in the Smpita\ConfigAs namespace. The helper method names follow the ConfigAs method names, but are prepended by config and are camelCased.

use function Smpita\ConfigAs\configString;

$typed = configString('config.key');
