Lighthouse 是一个由 Google 编写的工具，可以评估 Web 应用和页面，以及从出色的开发实践中收集性能指标和洞见等信息。我们一直主张性能测试乃第一公民, 五年前技术雷达中提到的对 Lighthouse 的补充内容对此也有帮助。我们关于适应度函数的思考，也为在构建流水线中运行 Lighthouse 这样的工具创造了强烈的动机。随着 Lighthouse CI 的引入，将 Lighthouse 纳入由不同工具管理的流水线，会变得比以往任何时候都容易。
Lighthouse is a tool written by Google to assess web applications for adherence to Progressive Web App standards. This year's Lighthouse 2.0 release adds performance metrics and accessibility checks to the basic toolset. This added functionality has now been incorporated into the standard Chrome developer tools under the audit tab. Lighthouse 2.0 is yet another beneficiary of Chrome's headless mode. This provides an alternative to Pa11y and similar tools for running accessibility checks in a continuous integration pipeline, since the tool can be run from the command line or standalone as a Node.js application.
