The screenshot method takes an optional single argument: a css-like selector of the element you want to capture.

It returns a base64 encoded buffer of the result.

The screenshot method generates a png file.

JavaScript

const { Chrome } = require('navalia');
const chrome = new Chrome();

chrome.goto('https://www.google.com')
.then(() => chrome.screenshot('body'))
.then(() => chrome.done());

TypeScript

import { Chrome } from 'navalia';
const chrome = new Chrome();

async function screenshot() {
  await chrome.goto('https://www.google.com');
  await chrome.screenshot('body');
  chrome.done();
}

screenshot();
