Small hint from our daily life as developers: If your default template for your ui component doesn’t show up, it might be, because you overwrote it in your template 😉
So you defined your default template like this:
;define([
// ...
'Magento_Ui/js/form/element/select',
// ...
], function (/* ... */ select, /* ... */) {
'use strict';
let self;
return select.extend({
defaults: {
elementTmpl: 'Customer_Plugin/shipping-option-select-element'
}
// ...
});
});
But then you overwrite it in your layout xml, like view/frontend/layout/checkout_index_index.xml
I tried to cleanup the XML to make it easier readable but not remove the inheritance. Not an easy job.

I was grepping through vendor/shopware/core for the hidden-gems series and stumbled over Shopware\Core\Service\AllServiceInstaller. Two-argument constructor, twelve lines of logic, @internal. Nothing dramatic — until I read what it actually does: it installs apps on your shop. By itself. In production. Once a day. Unless you told it not to. So this one isn’t going to […]
Twenty-three parts into this series, my research folder still has a stack of finds that are real, useful, undocumented — and about two paragraphs big. Instead of stretching each into a full post, here’s the lightning round. One problem, one gem, one file reference. Go. 1. rawUrl() — URLs for mail templates that actually work […]
A slow-burn bug report, verbatim from memory: „Google Search Console shows our sitemap is three months old. New categories aren’t in it.“ Three months. No errors in the log worth noticing, the scheduled task looks healthy, and regenerating „worked“ — or seemed to. The cause turned out to be a mechanism that’s completely reasonable and […]
