How do you audit web solutions with Chrome Lighthouse?

4 How to improve Chrome Lighthouse scores?

The Chrome Lighthouse scores are based on the metrics and the opportunities sections of the report. Therefore, to improve your scores, you need to focus on improving those aspects of your web solutions. For example, to improve your performance score, you need to reduce the loading time, the blocking time, and the main thread work of your web page or web app. To do that, you can use the suggestions in the opportunities and the diagnostics sections, such as using code splitting, lazy loading, caching, prefetching, etc. Similarly, to improve your accessibility score, you need to ensure that your web solutions are usable by people with disabilities. To do that, you can use the suggestions in the diagnostics section, such as adding alt text, labels, landmarks, captions, etc.

5 How to use Chrome Lighthouse for PWA?

Chrome Lighthouse can also help you evaluate your web solutions for PWA criteria, such as responsiveness, offline support, installability, etc. To do that, you need to select the Progressive Web App category in the Chrome Lighthouse pop-up window or the Audits panel. You will see a report with a checklist of PWA features, such as service worker, web app manifest, HTTPS, etc. You can use the report to see how well your web solutions meet the PWA standards and what you need to do to make them more progressive.

6 How to automate Chrome Lighthouse audits?

Chrome Lighthouse can also be automated using the command-line tool or the Node module. You can use these options to run Chrome Lighthouse audits on multiple web pages or web apps, or to integrate them with your continuous integration or continuous delivery (CI/CD) pipeline. You can also customize the audit configuration, such as the categories, the device type, the throttling, the budget, etc. You can use the lighthouse command or the lighthouse function to run Chrome Lighthouse audits programmatically and output the results in different formats, such as JSON, HTML, CSV, etc.
