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...
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,...
从React Compiler 开源到现在我连续研究分析 React Compiler 已经四天时间了,这期间我积累了大量的使用心得,整体感受就是它真的太强了!!!
在2024的React Conf上,React Compiler正式开源了,早在2021的React Conf上,由黄玄提出的React Forget(React without memo)概念,后改名为React Compiler。 注意React Compiler目前仍处于实验阶段,需要React 19 Beta不建议在生产中使用~。(可观看在React Conf中的介绍) https://react.dev/learn/react-compiler 使用场景...
React Compiler现在并不是一个初步想法,它已经在instagram.com的生产环境中提供支持了。 在去年React团队的一场演讲中,已经对它进行了介绍,只不过当时它的名字叫做React Forget,目前更名为React Compiler。 React Compiler基于Babel插件实现,它实际会做的事情,你可以简单这样理解: ...
with React Compiler, we don't need to do that anymore, So what exactly does the compiler do in this cases? It doesn't use useMemo or useCallback at all, Instead, the compiler manualy caches the values and resuses them if dependencies stay the same. ...
