How To Use Google CrUX To Analyze And Compare The Performance Of JS Frameworks

Website performance is crucial for user experience and can significantly impact a website's success. Users expect websites to load quickly and efficiently, and if they don't, they may leave and never come back. As a website owner, you need to analyze your website's performance regularly to ensure it meets users' expectations.
One tool you can use to analyze and compare website performance is Google's Chrome User Experience Report (CrUX). In this post, we'll discuss what CrUX is, how to use it, and how it can help you improve your website's performance.
What is Google CrUX?
Google CrUX is a dataset of real-world user experience metrics for millions of websites, collected from users who have opted into Google's anonymous data-sharing program. It provides data on key performance metrics such as page load time, time to first byte (TTFB), and first input delay (FID), which are essential for assessing website performance.
CrUX data is available in two forms: BigQuery and the CrUX API. BigQuery provides access to raw CrUX data, while the CrUX API provides a simplified interface to access the data.
How to use Google CrUX?
To use CrUX, you'll need to create a Google Cloud Platform account and set up a project. Once you have set up your project, you can use the BigQuery console or the CrUX API to access the data. To use BigQuery, you'll need to write SQL queries to retrieve the data you need. The BigQuery documentation provides examples of queries you can use to retrieve performance data for your website. Alternatively, you can use the CrUX API, which provides a more user-friendly interface to access the data. You can use the API to retrieve data on specific metrics, such as the percentage of users who experience a slow page load time.
How can Google CrUX help you improve your website's performance?
CrUX can help you identify performance issues on your website and compare your website's performance to other websites. You can use the data to identify areas for improvement and prioritize performance optimization efforts.
For example, you can use CrUX to analyze how your website performs on mobile devices compared to desktop devices. If you find that your website performs poorly on mobile devices, you can prioritize optimizing your website for mobile devices.
You can also use CrUX to compare your website's performance to your competitors' websites. If you find that your website performs poorly compared to your competitors, you can identify areas for improvement and work to optimize your website's performance. Conclusion
Google CrUX is a valuable tool for analyzing and comparing website performance. It provides real-world user experience metrics that can help you identify performance issues, prioritize optimization efforts, and improve your website's user experience. If you're serious about optimizing your website's performance, you should consider using Google CrUX to gain insights into your website's performance and identify areas for improvement.
