I'm working on my first Magento 2 project, and I'm slowly getting to grips with how everything works.
Then, I reach the point where I need to customize the checkout page and it throws a massive curveball, replacing the phtml/XML template system I've gotten used to with a completely different Knockout one.
In a nutshell, I store some personalization data in the quote item's "additional_data" field, and I need to show it in the checkout order summary.
I have successfully overridden
/frontend/web/template/summary/item/details.html with my own custom template, but I have no idea how to get the data from the product object and display it using Knockout.
Has anyone done anything similar they wish to share to get me started?
