How to get products from Shopify API NodeJS

A simple question: How do i get all the products in my store and log them to the console?

this:

     async function test() {
        fetch("/products")
        .then((res) => res.json())
        .then(data => console.log(data));
  }

returns an error:

Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0
