I am editing this file
RootFolder\vendor\magento\module-checkout\view\frontend\layout\checkout_index_index
To add new validations to the checkout.
For fields like telephone I just need to edit it like this:
<item name="telephone" xsi:type="array">
<item name="config" xsi:type="array">
<item name="tooltip" xsi:type="array">
<item name="description" xsi:type="string" translate="true">For delivery questions.</item> </item> </item>
<!-- Validation starts -->
<item name="validation" xsi:type="array">
<item name="validate-email" xsi:type="boolean">true</item> </item>
<!-- Validation ends -->
</item>
But I can't find where to add a validation to one of the address fields
Does somebody know how to add a validation to one of the address fields?
