描述

React will issue a warning in dev if you use onFocusIn or onFocusOut.

https://github.com/facebook/react/blob/85dcbf83/src/renderers/dom/shared/ReactDOMComponent.js#L196-L200

This should be easy enough to enforce for most cases with a linter rule.

Bad:

<div onFocusIn={() => {}} />

<div onFocusOut={() => {}} />

Good:

<div onFocus={() => {}} />

<div onBlur={() => {}} />

研究方向
Examine the React source code link in the issue to understand the warning. The rule should detect onFocusIn and onFocusOut attributes on JSX DOM elements (lowercase tag names). Check existing rules in the eslint plugin react repository for patterns on how to implement similar attribute restrictions. The issue has a single comment but no additional context from maintainers, so the scope is well defined.
