The equivalent to the jqx-all.js is the smart.elements.js. You can use it to import all the components.
Do not forget to import the CSS, smart.default.css.

If you want to import only a specific component, you should import it with its related module.
For example, if you want to import only the buttons: ‘source/modules/smart.button.js
