I need to get the customer email in homepage in a script.

Googling around I find mentions of window.customerData variable, but is always undefined (perhaps removed in latest versions?)

So at first I tried this:


but it fails with error:TypeError: can't convert undefined to object somewhere in customer-addresses.js

Then I tried with:


and then customerData.get('customer') but it gives me only first and last name or an empty object (even when the user is logged).

Is there a way to obtain the logged user email anywhere outside the checkout page?

  • have you find a way to retrieve customer email via js?

  • @LucaS Not out of the box. I ended up creating a new section to be called from customerData.get('myCustomSection') with the info I needed.

You need to create a plugin in order to save customer email to the local storage. So, add a frontend plugin configuration in di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Customer\CustomerData\Customer">
        <plugin name="additional_section_data" type="Your\Module\Plugin\AddCustomerEmail" />

And the plugin will look like this:


namespace Your\Module\Plugin;

use Magento\Customer\Helper\Session\CurrentCustomer;

class AddCustomerEmail
     * @var CurrentCustomer
    private $currentCustomer;

    public function __construct(
        CurrentCustomer $currentCustomer
    ) {
        $this->currentCustomer = $currentCustomer;

    public function afterGetSectionData(\Magento\Customer\CustomerData\Customer $subject, $result)
        if ($this->currentCustomer->getCustomerId()) {
            $customer = $this->currentCustomer->getCustomer();
            $result['email'] = $customer->getEmail();

        return $result;

  • Thank you, I ended up by doing something very similar: a custom data section.
