README
Symfony wrapper of the PHP client for the FeaturIT Feature Flag management platform.
Description
This package aims to simplify the integration of the FeaturIT API in a Symfony project.
Getting started
Dependencies
- PHP >= 8.0.2
- symfony/framework-bundle >= 5.2
- psr/http-client-implementation
- psr/simple-cache-implementation
Installing
composer require featurit/featurit-sdk-symfony -W
If there's no package providing psr/http-client-implementation, visit https://packagist.org/providers/psr/http-client-implementation and choose the package that better suits your project.
If there's no package providing psr/simple-cache-implementation, visit https://packagist.org/providers/psr/simple-cache-implementation and choose the package that better suits your project.
Inside your config/bundles.php file, add:
Featurit\Client\Symfony\FeaturitBundle::class => ['all' => true],
If you want to create your own configuration file in order to customize things
like the default FeaturitUserContextProvider, create a file in config/packages/featurit.yaml
with the following contents:
featurit:
tenant_identifier: '%env(FEATURIT_TENANT_IDENTIFIER)%'
environment_key: '%env(FEATURIT_ENVIRONMENT_KEY)%'
enable_analytics: '%env(FEATURIT_ENABLE_ANALYTICS)%'
cache_ttl_minutes: '%env(FEATURIT_CACHE_TTL_MINUTES)%'
send_analytics_interval_minutes: '%env(FEATURIT_SEND_ANALYTICS_INTERVAL_MINUTES)%'
featurit_user_context_provider: '@my_service_implementing_featurit_user_context_provider'
Basic Usage
That's how you would use Featurit in one of your controllers, services, or anywhere inside your PHP codebase:
your_method(Featurit $featurit)
{
if ($featurit->isActive('YOUR_FEATURE_NAME')) {
your_feature_code();
}
}
Or in order to check which is the version of your feature:
your_method(Featurit $featurit)
{
if ($featurit->version('YOUR_FEATURE_NAME') == 'v1') {
your_feature_code_for_v1();
} else if ($featurit->version('YOUR_FEATURE_NAME') == 'v2') {
your_feature_code_for_v2();
}
}
Twig extension
For convenience we provide 2 twig functions which allow to render html depending on the Feature Flag values.
Inside your twig template, you can use them like this:
<div>
<h2>This code will always be visible</h2>
{% if feature_is_active('MY_ACTIVE_FEATURE') %}
<h2>Welcome to MY_ACTIVE_FEATURE!</h2>
{% endif %}
{% if feature_version_equals('FEATURE_WITH_VERSIONS', 'v1') %}
<h2>Welcome to v1!</h2>
{% elseif feature_version_equals('FEATURE_WITH_VERSIONS', 'v2') %}
<h2>Welcome to v2!</h2>
{% endif %}
</div>
Defining your FeaturitUserContext
In order to show different versions of a feature to different users, Featurit needs to know about the attributes your user has in a certain context.
You can define the context using the as follows:
your_method(Featurit $featurit)
{
$contextData = get_your_user_context_data();
$featurit->setUserContext(
new DefaultFeaturitUserContext(
$contextData['userId'],
$contextData['sessionId'],
$contextData['ipAddress'],
[
'role' => $contextData['role'],
...
]
)
);
}
Defining a custom FeaturitUserContextProvider
This is an alternative to using $featurit->setUserContext(...);
.
By default, Featurit SDK for Symfony comes with a default FeaturitUserContextProvider
adapted for Symfony, but if you want to create your own, create a service un your services.yaml
file as follows:
services:
...
Namespace\For\MyFeaturitUserContextProvider
arguments:
- arg1
- arg2
- ...
And then add it to the featurit.yaml
config file as:
featurit:
...
featurit_user_context_provider: '@Namespace\For\MyFeaturitUserContextProvider'
Let's say that your platform users have a "role" attribute that you use to decide which features you show to each user. In that case you could create an implementation like:
<?php
namespace My\Namespace\Of\Choice;
use Featurit\Client\Modules\Segmentation\DefaultFeaturitUserContext;
use Featurit\Client\Modules\Segmentation\FeaturitUserContext;
use Featurit\Client\Modules\Segmentation\FeaturitUserContextProvider;
class MyCustomFeaturitUserContextProvider implements FeaturitUserContextProvider
{
public function getUserContext(): FeaturitUserContext
{
$userId = my_logic_to_get_the_user_identifier();
$sessionId = my_logic_to_get_the_session_id();
$ipAddress = my_logic_to_get_the_ip_address();
$role = my_logic_to_get_the_user_role();
return new DefaultFeaturitUserContext(
$userId,
$sessionId,
$ipAddress,
[
'role' => $role,
]
);
}
}
Then you must replace your implementation in the featurit.yaml
file as explained before.
And that should do it, from now on your segmentation rules will use the role attribute.
