@agent-infra/browser-ui is a CDP-based browser remote casting solution. It implements basic capability encapsulation based on @agent-infra/browser and can be directly referenced as a Web component by web pages.

Users only need to provide a CDP WebSocket URL with permissions, and @agent-infra/browser-ui can display the remote browser's page, and you can also manually intervene in browser operations, which is very useful in scenarios without VNC and headless browser.

Installation

npm install @agent-infra/browser-ui

Quick Start

Usage in FE projects:

import { BrowserUI } from '@agent-infra/browser-ui';

const container = document.getElementById('browserContainer');
if (!container) {
  throw new Error('Browser container element not found');
}

BrowserUI.create({
  root: container,
  browserOptions: {
    connect: {
      browserWSEndpoint: 'https://example.com/ws/url',
    },
  },
});

Or use the unpkg CDN to use it on any webpage:

CDN URL: https://unpkg.com/@agent-infra/browser/dist/bundle/index.js

<!doctype html>
<html lang="en">
  <body>
    <div id="browserContainer"></div>
    <script src="https://unpkg.com/@agent-infra/browser/dist/bundle/index.js"></script>
    <script>
      const BrowserUI = window.agent_infra_browser_ui.BrowserUI;

      BrowserUI.create({
        root: document.getElementById('browserContainer'),
        browserOptions: {
          connect: {
            // @ts-ignore
            browserWSEndpoint: 'https://example.com/ws/url',
          },
        },
      });
    </script>
  </body>
</html>

A complete usable example, which can be run directly with npm run dev in the current directory or viewed in the /examples directory within the package.
