Google Analytics is a free web analytics service that provides insights into your website or app's traffic and performance. By adding Google Analytics to your React, Next.js, or Gatsby.js application, you can track key metrics such as page views, bounce rate, and average session duration. This data can help you to understand how your users are interacting with your application and make informed decisions about how to improve it.
In this blog post, we'll show you how to add Google Analytics to your React, Next.js, and Gatsby.js applications. We'll also provide some code examples to help you get started.
Adding Google Analytics to React
To add Google Analytics to your React application, you'll need to install the react-ga package . You can do this by running the following command in your terminal:
npm install react-ga
Once you've installed the package, you'll need to import it into your React application. You can do this by adding the following line to the top of your index.js file:
import ReactGA from 'react-ga';
Next, you'll need to create a new Google Analytics property. You can do this by going to the Google Analytics website and clicking on the "Create Property" button.
Once you've created a property, you'll need to add the tracking ID to your React application. You can do this by setting the trackingId prop on the ReactGA component. For example:
<ReactGA trackingId="YOUR_TRACKING_ID" />
Finally, you'll need to add the Google Analytics snippet to your React application. You can do this by adding the following line to the <head> element of your index.html file:
<script src="https://www.google-analytics.com/analytics.js"></script>
Adding Google Analytics to Next.js
To add Google Analytics to your Next.js application, you'll need to install the next-analytics package. You can do this by running the following command in your terminal:
npm install next-analytics
Once you've installed the package, you'll need to import it into your Next.js application. You can do this by adding the following line to the top of your _app.js file:
import { GA_TRACKING_ID } from '../lib/gtag';
Next, you'll need to create a new Google Analytics property. You can do this by going to the Google Analytics website and clicking on the "Create Property" button.
Once you've created a property, you'll need to add the tracking ID to your Next.js application. You can do this by setting the GA_TRACKING_ID environment variable in your .env.local file. For example:
GA_TRACKING_ID=YOUR_TRACKING_ID
Finally, you'll need to add the Google Analytics snippet to your Next.js application. You can do this by adding the following line to the <head> element of your _document.js file:
<script src="https://www.google-analytics.com/analytics.js"></script>
Adding Google Analytics to Gatsby.js
To add Google Analytics to your Gatsby.js application, you'll need to install the gatsby-plugin-google-analytics package. You can do this by running the following command in your terminal:
npm install gatsby-plugin-google-analytics
Once you've installed the package, you'll need to add it to your Gatsby.js application's gatsby-config.js file. You can do this by adding the following line to the plugins array:
plugins: [
{
resolve: `gatsby-plugin-google-analytics`,
options: {
trackingId: 'YOUR_TRACKING_ID',
},
},
],
Finally, you'll need to add the Google Analytics snippet to your Gatsby.js application. You can do this by adding the following line to the <head> element of your index.html file:
<script src="https://www.google-analytics.com/analytics.js"></script>
