Can we use the Remix Js as a front end and node js as backend for Shopify App?

[RaviGohil2211]

Hello Guys

  I am creating an Import/Export app with Shopify remix but I am using Node js as an external backend,
Like I have created API in node js and clicked on the export button calling the API from Remix in Node js. 

Is that feasible way? If not then let me know how can handle a large amount of data in the Remix app template. Also, can handle file operations like generating an Excel file and downloading it? Any example or reference for this?

Please, help on this I am new to this platform. Any help would be appreciated.

Thank you
