内容驱动型 Web 应用前端的性能
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
性能是指 Web 应用的效率、速度和响应能力。加载时间过长且处于不活跃状态会导致跳出率较高且转化次数较少。因此,内容驱动型应用开发必须优先考虑性能,以确保用户可以顺畅高效地与应用互动。Web 应用的速度和响应能力对于各行各业十分重视;新闻应用需要尽快提供报道,电子商务应用必须快速加载产品以保持潜在客户的兴趣,文档或博客需要快速加载,以实现清晰的导航和读者满意度。
用于评估内容驱动型应用性能的工具包括:
核心网页指标工具包括以下几个方面,等等:

Slow load times and inactivity lead to high bounce rates and few\nconversions. Therefore, content-driven application development must prioritize\nperformance to make sure that users can interact with the application smoothly\nand efficiently. A web application's speed and responsiveness are valued across\nindustries; news applications are expected to provide articles as fast as\npossible, ecommerce applications must load products quickly to keep potential\ncustomers interested, and documentation or blogs demand quick loading for clear\nnavigation and reader satisfaction.\n\nTools for assessing the performance of content-driven applications include:\n\n- [PageSpeed Insights (PSI)](https://pagespeed.web.dev/): Run by web.dev is a tool to check the experience of mobile and desktop and provide suggestions on what to improve. This is powered by the Chrome User Experience Report (CrUX) dataset and checks for multiple types of experiences.\n- [Lighthouse](https://developer.chrome.com/en/docs/lighthouse/): Can be found in [Google Chrome Developer\n Tools](https://github.com/GoogleChrome/lighthouse) and has a [browser\n extension](https://chrome.google.com/webstore/detail/lighthouse/blipmdconlkpinefehnmjammfjpmpbjk) to measure many aspects of the web application such as performance, accessibility, best practices, SEO and PWA audits.\n\nThe [Core Web Vitals](https://web.dev/vitals/) tool includes the\nfollowing aspects, among others:\n\n- [Largest Contentful Paint (LCP)](https://web.dev/lcp/): measures loading performance. LCP should occur within 2.5 seconds of when the page first starts loading.\n- [First Input Delay (FID)](https://web.dev/fid/): measures interactivity. Pages should have a FID of 100 milliseconds or less.\n- [Cumulative Layout Shift (CLS)](https://web.dev/cls/): measures visual stability. Pages should maintain a CLS of 0.1. or less."]]
