Reactive programming makes you see more and further

响应式编程使你看得更远

简介切入

现代 web 开发的痛点:从只是展示静态的页面,到富交互的 web app

障碍:网页元素重绘延迟/网络请求延迟/交互的响应延迟带来的复杂状态维护

重点:让一切变成更及时、同步、可交互

马老师,您好!非常高兴能够采访到您。请您先简单介绍下目前您在豆瓣前端团队所负责的工作,以及团队情况。

你好,我是豆瓣阅读前端负责人马申彦,现在负责豆瓣阅读 web 前端的开发与维护,包括一个完整的 web 版电子书店、App 内嵌页面、原创作品的写作发布及后台审稿相关功能,日常运营相关活动与比赛等,阅读工程团队内前端组共 3 人,整个技术团队不超过 15 人,继承了豆瓣优良的技术氛围同时具有自主创新的产品方法。

豆瓣是Web2.0时代比较有代表性的网站,在信息聚合与用户分享的部分都做得非常好。现在移动应用越来越注重用户交互,前端可以从哪几个方面入手,实现创新?可否和我们分享豆瓣的一些具体实践?

用户交互与前端关系密切,影响用户体验的要素很多,简单来说分为页面加载与后续交互两部分,页面加载方面又分为 App 内嵌页面、传统服务器渲染页面和 SPA 页面等,这里面加载的体验效果是从前往后递减,App 内嵌页面直接打包在 App 内无需加载页面,只需要载入数据,但这需要和 App 通讯获取数据,所以开发时需要与客户端配合定义相关数据;服务器渲染页面一般适合纯展示的需求,特点是加载快但基本没有后续交互了;SPA 页面是前端自主控制数据的获取与存储等,可以有更多的交互操作,但缺点是 js 文件加载会导致出首屏慢,这时就需要通过 webpack 等进行分包或进行异步加载以提升载入速度。页面载入后的交互上一般会考虑以下几种情况:

  1. SPA 页面的话有路由问题,如何在路由间共享数据等,比如 redux,来方便切换路由时有足够数据渲染。
