Chrome Automation
Instrument headless Chromium instances natively from the server virtual machine. Generate screenshots, capture page states, and generate PDF invoices dynamically.
01
Headless Web Capture
Deploy the chromedp module to spin up isolated browser contexts, navigate to targets, and capture page buffers.
capture.js
import { chromedp } from 'kitwork';
const pngBytes = chromedp.capture("https://github.com", {
width: 1280,
height: 720
});
const pngBytes = chromedp.capture("https://github.com", {
width: 1280,
height: 720
});
02
Serving Screenshot Streams
Deliver binary PNG buffers straight back to the client request stream by using the response image handler.
server-capture.js
router.get("/screenshot").handle((req, res) => {
const targetUrl = req.query("url").text() || "https://github.com";
const pngBytes = chromedp.capture(targetUrl, {
width: 1280,
height: 720
});
return res.image(pngBytes);
});
const targetUrl = req.query("url").text() || "https://github.com";
const pngBytes = chromedp.capture(targetUrl, {
width: 1280,
height: 720
});
return res.image(pngBytes);
});
03
Advanced Options & Wait Policies
Control the browser life cycle. Customize selector loading rules and wait delays to ensure asynchronous client-side SPAs render fully before screenshot acquisition.
wait-policies.js
const pngBytes = chromedp.capture("https://github.com", {
width: 1920,
height: 1080,
waitSelector: ".dashboard-grid", // Wait until element loads
timeout: "5s" // Timeout ceiling limit
});
width: 1920,
height: 1080,
waitSelector: ".dashboard-grid", // Wait until element loads
timeout: "5s" // Timeout ceiling limit
});
