What is Google Lighthouse?

Google Lighthouse is a versatile tool designed to help developers improve the quality of their web pages. By running a series of audits against a URL, it generates a detailed report on how well the page performs in areas such as performance, accessibility, SEO, and more. Each audit provides a score, helping developers identify areas for improvement.

Key Features of Lighthouse:

  • Performance Metrics: Analyzes page load speed, rendering times, and other performance-related aspects.

  • Accessibility: Checks for issues that might affect users with disabilities.

  • Best Practices: Ensures the application adheres to modern web standards.

  • SEO: Provides insights to improve search engine optimization.

  • Progressive Web App (PWA) Capabilities: Audits for PWA best practices.

Why Automate Lighthouse Scores?
While Lighthouse is an invaluable tool, running audits manually can be time-consuming and subject to human error. Automation solves these issues by integrating Lighthouse into your continuous integration/continuous deployment (CI/CD) pipeline.
