What version of Oxlint are you using?

1.70.0

What command did you run?

oxlint

What does your .oxlintrc.json (or oxlint.config.ts) config file look like?

import { defineConfig } from 'oxlint';

export default defineConfig({
	plugins: ['react'],
	rules: {
		'react/display-name': ['warn', { ignoreTranspilerName: true }],
	},
});

What happened?

Testing.tsx

export default function Testing() {
	const renderThing = () => <div>Thing</div>;
	return <div>{renderThing()}</div>;
}
Testing.displayName = 'Testing';

Output from npx oxlint:

  ⚠ react(display-name): Component definition is missing display name.

  help: Add a `displayName` property to the component.

Found 1 warning and 0 errors.

• Changing to const ThingComponent = () => <div>Thing</div>; and rendering as <ThingComponent /> still works and is also reported by the equivalent ESLint rule, but only oxlint reports the lowercase version.
• Changing to const renderThing = () => 'Thing'; removes the error.
