I found a product configurator on github, based on node.js and react and I want to use it in my store. To integrate it, I thought I need to implement an App. Is this the right way, as the functionality should be displayed in the front end?
What are the best steps to be able to display the configurator?
As Shopify specified, you should use a custom app. Custom apps can be used to add features to your Shopify admin or to extend your online store to other platforms using custom storefronts.
Please let me know if you have any further questions.
