经过验证发现由于 React19 之前的版本内部不包含 compiler-runtime,因此无法正常使用,我猜测可能会在以后提供插件来支持编译老版本的项目。目前我是在 React 19 RC 版本中结合 Compiler。不过好消息是将项目升级到 React 19 难度并不高。许多三方库也已经积极的适配了 React 19 1、如何查看编译
i以前叫 React Forget,现改名为 React Compiler 要了解 React Compiler,这还需要从 React 的更新机制说起。React 项目中的任何一个组件发生 state 状态的变更,React 更新机制都会从最顶层的根节点开始往下递归对比,通过双缓存机制判断出哪些节点发生了变化,然后更新节点。这样的更新机制成本并不小,因为在判断过程中,...
React 19 版本引入了一个重要的新特性,即React Compiler。这个编译器是 React 团队为了解决在状态变化时 UI 过度重新渲染的问题而开发的。React Compiler 旨在自动优化应用程序,通过在构建时分析代码,理解 JavaScript 和 React 的规则,从而自动地进行记忆化(memoization)处理,减少不必要的组件重新渲染 什么是React编译器...
杰克-赫林顿(Jack Herrington)在他最近的视频(React Compiler: In-Depth Beyond React Conf 2024)中对此做了很好的概述,如果你想了解实际细节的话。或者,如果你想彻底打破思维定势,真正了解其中的复杂性,请观看 "React Compiler Deep Dive "讲座,其中 Sathya Gunasekaran 解释了编译器,然后Mofei Zhang在 20 分钟内...
