⏱ 看了 web.dev 的 631 篇博客，我总结了这些内容

最近在做 web 性能优化的工作，所以想集中学习了解一下相关的专题内容。这部分内容肯定要学习一手信息，所以找先找了 https://web.dev/[1]，一个 Google 官方推出的一个面向 Web 开发者的网站，里面有非常多的教程和最佳实践，非常适合有性能优化诉求的开发者去浏览和学习。

网站的核心部分分为 4 类：

Learn[2]：体系化的教程，例如性能优化和 PWA
Measure[3]：就是一个在线版本的 Lighthouse，和 Chrome DevTools 的 Performance 功能一致
Case Study[4]：优化案例（商业互吹），内容一般为采用 X 优化带来数据 Y 的提升最终带来 Z 的商业增长
Blog[5]：内容较杂，优化教程/API 解读/优化案例等等都有涉及

从上面的结构可以看出，Lean/Measure/CaseStudy 这三个章节内容都是比较体系化的，但是 Blog 内容却没有一个很好的分类。以我的阅读经验，Blog 里有一些非常好的文章，所以我很好奇 Blog 章节里有多少好东西可供挖掘，于是上个月的时候花了一些时间，把所有的 Blog 读了一遍，并以自己的认知对内容做了分析和总结，以便自己后续回顾与搜索。

内容分类：

截止到目前为止（2022-7-7），web.dev 一共发布了 631 篇 blog，从 blog 的内容和发布时间可以很明显的看出 google 官方的发力（营销）方向，比如说前几年在推 PWA[6]，这两年在推 Web Vitals[7]。纵观下来，Blog 的内容可以分为以下几类

性能指标：例如 Web Vitals，FMP，TTI 这些概念和相对应的优化策略
优化策略：例如对网络的优化，对图片/字体/CSS/JS 的优化
UI/UX：这部分内容偏向于实战和设计，最终会产出一些 UI Component
Web 特性：例如 Web Worker，WebXR，Wasm 等功能的介绍和教程
提案/API：主要是对一些提案的实现和现代浏览器 API 的介绍，内容偏向于文档，对开发者来说距离较远
商业案例：其实就是 Case Study[8] 章节的内容，只不过这部分内容也收录在 Blog 里

1.性能指标

种类	篇数	时间跨度
性能指标/优化/监控	34	主要为 2018 - 2022

性能指标绝对是 Google/Chrome 这两年首推的内容了，从 2018 年到 2022，4 年的时间里就推出了 34 篇文章，最近两年的商业案例也基本都是「优化 Web Vitals 指标带来商业收益的」的套路。文章整体的质量都不错，从原因到解决方案到具体用例都有涉及。

2.优化策略

种类	篇数	时间跨度
网络优化	46	主要为 2018 - 2022
渲染	28	主要为 2013 - 2015，2018 做了相关修订
图片优化	13	主要为 2019
JS/JS 框架	15	主要为 2020 - 2021
font	8	2020 - 2021

从文章比例上就可以看出，Web 非常关注网络资源的优化，这是 Web 的优点也是 Web 的痛点，JS 运行的再快也扛不住一次网络异常，所以网络优化的内容非常多。

渲染优化的文章主要集中到 13-15 年，最近几年很少说了，这个和历史发展潮流也差不多，13-15 年属于移动互联网高速发展时期，Native 开发还是如日中天，Web 在渲染性能上确实不如 Native，现如今随着内核的发展以及终端机性能的提升，渲染基本上已经不是性能瓶颈了，而且浏览器渲染模块对于 Web 开发者来说也很难去介入，所以内容较少也在情理之中。

JS 优化内容也比较少，一是对于大部分场景来说开发者还没有到优化 JS 解决性能瓶颈，二是很多 JS 优化的内容都搬到 https://v8.dev/blog[9] 了，所以只有几篇早期的文章；JS 框架层的优化最近有一些，例如和 nextjs，react 的合作之类的。

图片视频字体的优化都属于资源优化，内容也不错，可以一起看看单项突破。

3.UI/UX

种类	篇数	时间跨度
CSS新特性/新属性	27	主要为 2019 - 2020
UI 组件/设计	12	主要为 2021
交互	15	2019 - 2021

CSS 主要介绍的是一些 CSS新特性新属性，还有一些关于 CSS 的使用/优化文章。

UI 是最近有些 blog 写了些 UI 组件，感觉内容也可以学习一下。UX 内容就比较杂了，涉及到交互效果，可访问性等内容，相对来说这个分类里跨学科内容多一些。

4.Web 特性

种类	篇数	时间跨度
Web Worker/Service Worker	22	主要为 2020
PWA	16	主要为 2019 - 2020
浏览器	18	2018-2021
安全	10	主要为 2020 - 2021
WebGL/WebGPU	6	2012
WebXR	10	2017、2020
Wasm	8	2018 - 2021
Web Component	13	2016、2017

PWA 在前几年 Google 一直在推，但在国内其实一直不温不火的，大公司都有自己的 Hybrid H5 方案，小公司基本都去做小程序开发了；国外看似好一些，但做的最好的 twitter PWA，但我深度体验一年后，发现和 Native 应用比差距还是很大，这已经算全世界做的最好的 PWA APP 了，由此可见 PWA 推广道路之艰辛。不过 PWA 还是有很多值得学习参考的知识点的，还是有必要学习一下的。

Web Worker/Service Worker 加起来也有 22 篇文章，Web Worker 主要用来分散主线程的计算任务，Service Worker 主要起 Web Network 拦截器的作用（从效果上其实也可以归类到网络性能优化里），内容也是值得学习的。

浏览器分类主要是一些我不知道怎么分类的浏览器特性，比如说 BFCache，Web 存储方案介绍等等，内容相对较杂。

剩下的内容其实都比较散：

WebGL/WebGPU 的内容不多，而且成文时间也很早，而且 Web 3D 虽然依托于浏览器平台，但实际上和传统的 Web 开发完全是两回事，所以内容少也可以理解
WebXR 内容也很少，主要还是功能介绍
Wasm 内容也较少，主要是入门教程
安全领域主要是对一些安全特性/安全 API 做的介绍
Web Component 有几篇很不错的系列教程可以当入门文章看

其实这些功能都属于叫好不叫座的状态，它们都大大提高了 Web 的上限，但是现实是没有几家公司需要突破传统 Web 的上限，大家其实都遵循一个原则——能跑就行。

5.提案/API

种类	篇数	时间跨度
提案/实验性功能/新 API	42	主要为 2019-2022

这部分内容对于普通开发者来说其实不是很必要。一是提案/实验性功能/新 API都比较新，有兼容性问题，一般很难在项目中落地；二是在现实场景里，基本上很少有需求需要用到 Web 的 File API/Bluetooth API 等功能，一般这些场景都是遇到再看，所以这部分内容其实只要知道有就可以，要用到再看细节也不迟。

Blog 链接

这部分内容是整理出的 Blog 内容，我对其标注了发布时间和文件标题，并对一些内容做了简评，方便后续搜索和查看。
