How to override an HTML file in a custom module

Question

I am developing a custom module for a payment method in magento 2. Currently I am using cc-form.html from the vendor directory and the module is working fine. see below path.

vendor/magento/module-payment/view/frontend/web/template/payment/cc-form.html

Is there any way to override the HTML file?

Answer 1

Yes, there is. You can look in pub static to see how path to static asset constructed.

How it works

Every asset is accessible from the page by itenter code heres "RequireJS ID". It similar to real path, but varied.

For example file http://magento.vg/static/adminhtml/Magento/backend/en_US/Magento_Theme/favicon.ico.

It's real path is /app/code/Magento/Theme/view/adminhtml/web/favicon.ico.
It's RequireJS ID is Magento_Theme/favicon.ico. This means that file could be accessible via require("text!Magento_Theme/favicon.ico") or similar command.

You can find that RequireJS ID consist with module name and useful part of path (after folder web).

How can I replace a file

So you have file
vendor/magento/module-payment/view/frontend/web/template/payment/cc-form.html

On the page it loaded with src as
http://magento.vg/static/frontend/Magento/luma/en_US/Magento_Payment/template/payment/cc-form.html

So its RequireJS ID is
Magento_Payment/template/payment/cc-form.html

Side note: Inside UI components stuff it equals to Magento_Payment/payment/cc-form. Words "template" and ".html" are added automatically.

And now you can replace this file for application via RequireJS config

var config = {
  "map": {
    "*": {
      "Magento_Payment/template/payment/cc-form.html": 
          "<OwnBrand>_<OwnModule>/template/payment/cc-form.html"
    }
  }
};

This code snippet you place in requirejs-config.js file in your module. That is all.
