Customize the Magento 2 Checkout
Checkout customization looks fragile. It is just another UI Component tree.
Modifying Magento's checkout feels like defusing a bomb. One wrong change and the whole flow breaks, usually somewhere you didn't touch.
The checkout is a tree of UI Components and a set of totals, shipping, and payment steps that all depend on each other's state. A field you add in one step can silently break validation two steps later, because the checkout doesn't fail loud -- it just stops moving.
This course takes the checkout apart one step at a time.
Adding a custom field first, then a new step, then custom validation and payment logic. Each lesson ends with a checkout you can walk through in the browser and confirm still works.
This is step two of advanced development. When you finish, Admin Grids & Forms is next, because it is the same UI Component pattern applied to the admin panel. It is also included in the University.
You leave able to change the checkout without holding your breath.
