react/jsx-no-undef Correctness

Disallow undeclared variables in JSX.

Note that this rule is generally unnecessary if you are using TypeScript, as TypeScript will catch undeclared variables for you.

It is most likely a potential ReferenceError caused by a misspelling of a variable or parameter name.

Examples of incorrect code for this rule:

jsx

const A = () => <App />;
const C = <B />;

How to use

To enable this rule using the config file or in the CLI, you can use:

Config (.oxlintrc.json)Config (oxlint.config.ts)CLI

json

{
  "plugins": ["react"],
  "rules": {
    "react/jsx-no-undef": "error"
  }
}

import { defineConfig } from "oxlint";

export default defineConfig({
  plugins: ["react"],
  rules: {
    "react/jsx-no-undef": "error",
  },
});

bash

oxlint --deny react/jsx-no-undef --react-plugin

This rule was added in v0.1.1.
