Page Navigation

This feature allows you to navigate to a specific URL and wait for the page to load. The code sample demonstrates how to use the Page domain to navigate to 'https://example.com' and wait for the load event.

const CDP = require('chrome-remote-interface');

(async function() {
  const client = await CDP();
  const { Page } = client;
  await Page.enable();
  await Page.navigate({ url: 'https://example.com' });
  await Page.loadEventFired();
  console.log('Page loaded');
  await client.close();
})();

JavaScript Execution

This feature allows you to execute JavaScript code within the context of the web page. The code sample demonstrates how to evaluate a JavaScript expression to get the page title.

const CDP = require('chrome-remote-interface');

(async function() {
  const client = await CDP();
  const { Runtime } = client;
  await Runtime.enable();
  const result = await Runtime.evaluate({ expression: 'document.title' });
  console.log('Page title:', result.result.value);
  await client.close();
})();

Network Monitoring

This feature allows you to monitor network requests made by the web page. The code sample demonstrates how to listen for network requests and log the URLs of the requests.

const CDP = require('chrome-remote-interface');

(async function() {
  const client = await CDP();
  const { Network } = client;
  await Network.enable();
  Network.requestWillBeSent((params) => {
    console.log('Request:', params.request.url);
  });
  await client.Page.navigate({ url: 'https://example.com' });
  await client.Page.loadEventFired();
  await client.close();
})();
