How to pass user input (front-end) into a scraper (back-end)?

I'm trying to grab a user-input of a product URL, scrape key product information, and show it on the front-end.I'm using Node.JS, Express, and Webpack to use modules in the browser; however, I'm unable to using scraping modules in the script I included in the browser because I'll get "No 'Access-Control-Allow-Origin' header is present on the requested resource".I understand that I'll be unable to make get request to URLs I don't have access to on the browser. But I'm confused.How do I go about implementing this product scraper and structuring my code?
