Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Features

  • Chrome: Create Tab: Open new browser targets with optional navigation and native "Wait for Page Load" event handling.
  • Chrome: Read Web Page: Extract innerText or outerHTML from an existing tab session via WebSocket.
  • Chrome: Run Script: Execute custom asynchronous JavaScript within the page context and return JSON results directly to n8n.

Installation

Follow the official n8n guide to install this package:

  1. Go to Settings > Community Nodes in your n8n instance.
  2. Click on Install a community node.
  3. Enter n8n-nodes-chrome-cdp in the npm Package Name field.
  4. Agree to the risks and click Install.

Prerequisites

This node requires a running Chromium-based browser (Chrome, Edge, or Brave) with the remote debugging port enabled.

Recommended Startup Command

Launch your browser with the following flags to allow n8n to connect:

chrome --remote-debugging-port=9222 --remote-debugging-address=0.0.0.0 --incognito

Note: Ensure your firewall or network settings allow traffic on port 9222.

Node Documentation

1. Chrome: Create Tab

Initializes a new browser tab and returns connection details.

  • Host: The IP or hostname of your Chrome instance.
  • URL: The destination address (defaults to about:blank).
  • Wait for Page Load: If enabled, pauses execution until the browser triggers loadEventFired.

2. Chrome: Read Web Page

Connects to an active session to pull content without re-navigating.

  • WebSocket URL: The wsUrl provided by the Create Tab node.
  • Extract Type: Choose Text for a clean string or HTML for the raw source code.
  • Wait for Navigation: Ensures the DOM is fully settled before extraction.

3. Chrome: Run Script

Injects and executes custom logic inside the browser.

  • JavaScript Code: Your script. Supports async/await. Use return to pass data back to the workflow.
  • Wait for Navigation: Optional flag to delay execution until the page is ready.
