ahmadrosid / laravel-env-feature-flags

A simple package for managing feature flags in Laravel applications using environment variables.

Laravel Feature Flag

Sometimes, you need to develop a feature that you want to test in production, but you don't want your users to see it yet. That's where storing feature flags using an environment variable file (.env) comes in handy. This package will allow you to do that easily.

Install

composer require ahmadrosid/laravel-env-feature-flags

How to use

1. Define Feature Flags in .env:

In your .env file, you can define your feature flags as environment variables. For example:

FEATURE_NEW_DESIGN=true
FEATURE_PAYMENT_GATEWAY=false

2. Access Feature Flags in Your Code:

You can use the Features facade provided by the package to check the status of your feature flags:

use Ahmadrosid\FeatureFlags\Features;

if (Features::enabled('new_design')) {
    // Code for the new design feature
} else {
    // Code for the old design
}

Note that the enabled method expects a snake_case string as the feature name, so FEATURE_NEW_DESIGN becomes new_design.

3 Add Feature Flag Checks in Blade Templates:

If you want to conditionally render parts of your Blade templates based on feature flags, you can use the @feature Blade directive provided by the package:

@feature('new_design')
    <!-- Code for the new design feature -->
@else
    <!-- Code for the old design -->
@endfeature

You can also use Blade directive called @hasAccess. This directive can be used in your Blade templates to check if the current user has access to a specific feature. If the user doesn't have access, you can display a message or perform any other action you need.

@hasAccess('new_design')
    <!-- Code for the new design feature -->
@else
    <div class="alert alert-warning">
        You don't have access to the new design feature.
    </div>
@endhasAccess

To enable this you need to add this flag in you .env file.

FEATURE_NEW_DESIGN_USERS=1,2,3
