Answer 1

Please add a root endpoint for the application.

something like

app.get("/", (req,res)=>{
 res.send({message:"hello world"})
})

Answer 2

You can use the removeAttribute() method of HTMLElement.

First, you need to select the element. There are several ways, I prefer to use querySelector(). The query selects a a element with the class cart-contents and the attribute data-toggle.

Then, simply call the removeAttribute method.

Full Code

const $toRemoveAttrElem = window.document.querySelector("a.cart-contents[data-toggle]");
$toRemoveAttrElem.removeAttribute("data-toggle");
