Frontend
Is Enabled Determiner

3min
Klevu/Frontend/Service/IsEnabledDeterminer.php determines if we should output to the frontend.
We pass a multi-dimensional array of Klevu\FrontendApi\Service\IsEnabledCondition\IsEnabledConditionInterface to the determiner.
And Condition
Any condition at the top level of the array is treated as an AND condition.
e.g.
Klevu/Frontend/etc/frontend/di.xml
<type name="Klevu\Frontend\ViewModel\CustomerGroupSuffix">
    <arguments>
		<argument name="isEnabledConditions" xsi:type="array">
		    <item name="klevu_integrated"
		          xsi:type="object">Klevu\Frontend\Service\IsEnabledCondition\IsStoreIntegratedCondition</item>
		    <item name="klevu_customer_group_price_enabled"
		          xsi:type="object">Klevu\Frontend\Service\IsEnabledCondition\IsCustomerGroupPriceEnabledCondition</item>
		</argument>
	</arguments>
</type>

<type name="Klevu\Frontend\ViewModel\CustomerGroupSuffix">
    <arguments>
		<argument name="isEnabledConditions" xsi:type="array">
		    <item name="klevu_integrated"
		          xsi:type="object">Klevu\Frontend\Service\IsEnabledCondition\IsStoreIntegratedCondition</item>
		    <item name="klevu_customer_group_price_enabled"
		          xsi:type="object">Klevu\Frontend\Service\IsEnabledCondition\IsCustomerGroupPriceEnabledCondition</item>
		</argument>
	</arguments>
</type>
﻿
Here we only output the customer price group suffix if both this store is integrated with Klevu and Customer Group Pricing is enabled in the admin.
Or Condition
Any condition at any lower level of the array is treated as an OR condition.
e.g.
Klevu/FrontendSearch/etc/frontend/di.xml
<type name="Klevu\Frontend\ViewModel\CurrencyConversion">
    <arguments>
        <argument name="isEnabledConditions" xsi:type="array">
            <item name="klevu_modules_enabled" xsi:type="array">
                <item name="klevu_quick_enabled"
                      xsi:type="object">Klevu\FrontendSearch\Service\IsEnabledCondition\IsQuickSearchEnabledCondition</item>
                <item name="klevu_srlp_enabled"
                      xsi:type="object">Klevu\FrontendSearch\Service\IsEnabledCondition\IsSrlpEnabledCondition</item>
            </item>
        </argument>
    </arguments>
</type>

<type name="Klevu\Frontend\ViewModel\CurrencyConversion">
    <arguments>
        <argument name="isEnabledConditions" xsi:type="array">
            <item name="klevu_modules_enabled" xsi:type="array">
                <item name="klevu_quick_enabled"
                      xsi:type="object">Klevu\FrontendSearch\Service\IsEnabledCondition\IsQuickSearchEnabledCondition</item>
                <item name="klevu_srlp_enabled"
                      xsi:type="object">Klevu\FrontendSearch\Service\IsEnabledCondition\IsSrlpEnabledCondition</item>
            </item>
        </argument>
    </arguments>
</type>

Here we output the currency conversion javascript if either quick search or search results landing page are enabled as they both require currency conversions.
Combining And & OR
As each module injects its own configuration that consolidated CurrencyConversion XML will look like this
XML
<type name="Klevu\Frontend\ViewModel\CurrencyConversion">
    <arguments>
        <argument name="isEnabledConditions" xsi:type="array">
            <item name="klevu_integrated" xsi:type="object">Klevu\Frontend\Service\IsEnabledCondition\IsStoreIntegratedCondition</item>

Here we only output the currency conversion javascript if 
Both 
    klevu_integrated - the store is integrated with Klevu 
AND 
    klevu_modules_enabled - at least one of these options is enabled.
        Either 
        klevu_catnav_enabled - Category Navigation is rendered with Template JS
        OR 
        klevu_recs_enabled - Recommendation is enabled 
        OR
         klevu_quick_enabled - Quick Search is enabled
        OR
        klevu_srlp_enabled - Search Result Landing Page is rendered with Template JS
i.e. If the store is integrated and one of the options that requires currency conversion is enabled.
