Examples
Wait before taking screenshot with JavaScript and Selenium
Install Selenium for JavaScript
npm install selenium-webdriver selenium-webdriver includes Selenium Manager, which downloads the right chromedriver automatically. The examples use ES modules — run them with node file.mjs, or set "type": "module" in your package.json.
Take a screenshot and save to file
Wait for the page to settle before taking the screenshot.
import { Builder, By, until } from 'selenium-webdriver';
import chrome from 'selenium-webdriver/chrome.js';
import { writeFileSync } from 'node:fs';
const options = new chrome.Options().addArguments('--headless=new');
const driver = await new Builder().forBrowser('chrome').setChromeOptions(options).build();
await driver.get('https://www.htmltoimage.com/demo');
// Wait for late content — here an element that appears after 2 seconds.
await driver.wait(until.elementIsVisible(driver.findElement(By.css('#delayed-banner'))), 5000);
const image = await driver.takeScreenshot();
writeFileSync('wait.png', image, 'base64');
await driver.quit(); Find out how to take a full-page screenshot with JavaScript and Selenium.
That was 16 lines of code — plus a browser to run in production
Keeping headless browsers fed, patched and scaled is a job in itself. We built Urlbox so the same screenshot is one API call:
curl "https://api.urlbox.com/v1/YOUR_API_KEY/png?url=https://example.com" Try the Urlbox screenshot API — free trial, no browser babysitting.
