Getting the URL of a CSS background image in NodeJS and Express: A step-by-step guide

I've recently learned that using getComputedStyle in a Node environment is not possible due to it being a browser-specific behavior.

Despite this, I am still interested in retrieving all background image URLs within Node and downloading them as shown below

const divs = document.querySelectorAll("div");
Array.from(divs).filter((div) => {
    let backgroundImage = window.getComputedStyle(div).getPropertyValue("background-image");

Unfortunately, this approach isn't feasible.

Is there a way to retrieve all div elements with background-image URLs as styles in NodeJS?

Answer №1

To retrieve the data required, consider utilizing a headless browser such as puppeteer to display the webpage. Extract all necessary information from the browser and transmit it back to Node.js. This approach should prove beneficial.

Best regards, omi

Answer №2

let allDivs = document.querySelectorAll("div");
let divBackgrounds = allDivs.map(div=>div.style.backgroundImage)
console.log(divBackgrounds)
// Result: ['url("https://www.picture.com/profile.png")','url("https://www.picture.com/profile2.png")']
