The Full Story:
Google Chrome team has announced an update to Lighthouse, version 11.2.0, which brings several changes to PageSpeed Insights. Lighthouse is an open-source tool that helps developers improve the quality and performance of their web pages. It provides audits for various aspects of a website, including performance, accessibility, and SEO.
The latest update to Lighthouse includes new audits, improvements to existing audits, and bug fixes. One of the key changes is the introduction of more accurate performance metrics. Lighthouse now uses a new metric called Largest Contentful Paint (LCP) to measure the time it takes for the largest element on the page to become visible to the user. This metric provides a more realistic measure of how quickly a page loads and helps developers identify areas for improvement.
In addition to the new performance metrics, Lighthouse now provides better recommendations for improving website speed. The tool analyzes the page and suggests optimizations that can be made to reduce load times. These recommendations are based on best practices and can help developers make their websites faster and more user-friendly.
Another significant addition in the update is a new audit for detecting unused JavaScript and CSS code. This audit helps developers identify code that is not being used on their website, which can be safely removed to improve performance. Removing unused code can reduce the size of the page and make it load faster.
The update also includes improvements to existing audits. For example, the audit for image optimization now provides more detailed information about the potential savings that can be achieved by optimizing images. This can help developers prioritize their optimization efforts and make informed decisions about image compression and resizing.
Furthermore, the update addresses several bugs and issues reported by users. These bug fixes ensure that Lighthouse provides accurate and reliable results, allowing developers to make informed decisions about optimizing their websites.
The new version of Lighthouse, 11.2.0, is available for use in the Chrome DevTools. Developers can access Lighthouse by opening the Chrome DevTools, navigating to the Audits tab, and selecting “Run audits.” The tool will analyze the page and provide a detailed report with recommendations for improvement.
Lighthouse 11.2.0 is also available in the PageSpeed Insights tool, which allows developers to analyze the performance of their websites. By entering a URL into the tool, developers can get a report that includes performance metrics, optimization recommendations, and other insights.
Overall, the update to Lighthouse brings several improvements to PageSpeed Insights. The new version provides more accurate performance metrics, better recommendations for improving website speed, and a new audit for detecting unused JavaScript and CSS code. These changes can help developers optimize their websites and provide a better user experience.
