v0 and Crazy Egg integration: Step-by-Step Guide 2025

Creating the Crazy Egg Loader File

• Create a new file in your project under the folder src/utils and name it crazyEggLoader.ts.
• This file will contain the TypeScript code that dynamically adds the Crazy Egg script to your web page.

export function loadCrazyEgg(): void {
  // Prevent duplicate loading if the script is already added
  if (document.getElementById('crazyegg-script')) {
    return;
  }

  // Create a new script element
  const script = document.createElement('script');
  script.id = 'crazyegg-script';
  script.type = 'text/javascript';
  script.async = true;
  // Replace 'YOURSCRIPTID' with the actual Crazy Egg script ID provided by Crazy Egg
  script.src = 'https://script.crazyegg.com/pages/scripts/YOURSCRIPTID.js?' + Date.now();
  // Append the script to the document head
  document.head.appendChild(script);
}

Integrating the Loader into Your Main Application

• Locate your main TypeScript file that serves as the entry point for your app. This could be something like src/App.tsx if you are using React or another file if not.
• You need to import and call the loadCrazyEgg function so that the Crazy Egg tracking code is loaded when your app starts.
• If you are using React, you can use the useEffect hook to load the script once the component mounts.

import React, { useEffect } from 'react';
import { loadCrazyEgg } from './utils/crazyEggLoader';

const App: React.FC = () => {
  useEffect(() => {
    // Load Crazy Egg script when the component is mounted
    loadCrazyEgg();
  }, []);
  return (
    

      {/ Your app content goes here /}
      Welcome to My App!
    

  );
};

export default App;

Integrating for Non-React Projects

• If your project is not using React, simply import and call loadCrazyEgg in your main TypeScript file (for example, src/main.ts) after the DOM has loaded.
• You can add an event listener for DOMContentLoaded to ensure the script is loaded after the page content is ready.

import { loadCrazyEgg } from './utils/crazyEggLoader';

document.addEventListener('DOMContentLoaded', () => {
  // Load Crazy Egg tracking script once the DOM is fully loaded
  loadCrazyEgg();
});

No Terminal Dependency Installation Needed

• Since the v0 project does not have a terminal, and the code above uses pure TypeScript and browser APIs, no additional dependencies need to be installed.
• Simply add these files to your project structure and the code will work without any extra installation steps.
