Installing Hyvä CSP Default Theme

To install the CSP-compatible version of Hyvä Theme, follow the regular installation instructions but replace the package hyva-themes/magento2-default-theme with hyva-themes/magento2-default-theme-csp.

composer require hyva-themes/magento2-default-theme-csp

Hyva/default-csp vs Hyva/default

The CSP-compatible version of the theme uses the theme-name Hyva/default-csp. When migrating a custom theme to be CSP compatible, the parent theme name needs to be updated accordingly in the theme.xml file

    <theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
        <title>My Theme</title>
        <parent>Hyva/default-csp</parent>
        <!--<parent>Hyva/default</parent>-->
    </theme>

Installing the default and the default-csp theme side-by-side

The regular and the CSP-compatible version of the default-theme can be installed side-by-side.

composer require hyva-themes/magento2-default-theme
composer require hyva-themes/magento2-default-theme-csp

This is not required but can be useful while migrating a custom child theme to be strict CSP-compatible.
