A simple trait to enable a feature system using Enums:
if(AppFeature::welcome_email->enabled()){
Mail::to($newUser)->send(new WelcomeEmail($newUser));
}You can install the package via composer:
composer require defstudio/enum-featuresFeatures can be enabled on any enum by using the DefinesFeatures trait:
use DefStudio\EnumFeatures\EnumFeatures;
enum AppFeature
{
use DefinesFeatures; // ← simply add this
case multi_language;
case impersonate;
case welcome_email;
}and each feature can then added to the Laravel application in its configs/app.php file:
// config/app.php
return [
//..
'features' => [
AppFeature::multi_language,
AppFeature::welcome_email,
]
]then, in code, a feature could be checked to be enabled:
if(AppFeature::multi_language->enabled()){
//.. multi language specific code
}or be disabled
if(AppFeature::impersonate->disabled()){
throw(new Exception("Impersonate feature is not enabled"));
}or enforced
AppFeature::impersonate->enforce(); //throws "Feature [impersonate] is not enabled"In blade files, a feature can be checked with @feature directive:
@feature(AppFeature::multi_language)
<select name="language" xmlns="http://www.w3.org/1999/html">
<option value="en">English</option>
<option value="fr">French</option>
<option value="it">Italian</option>
</select>
@endfeatureEnabled features are usually stored in config('app.features'), but this behaviour can be customized by
overriding the enabledFeatures() static method inside the enum class:
use DefStudio\EnumFeatures\EnumFeatures;
enum AppFeature
{
use DefinesFeatures; // ← simply add this
case multi_language;
case impersonate;
case welcome_email;
public static function enabledFeatures(): array
{
return config('my_package.features', []); //or load from DB, or every other method
}
}note: changing how enabled features are checked makes this package framework agnostic and it can be used in any php applicaiton
