require-usememo

Deprecated compatibility alias for no-unstable-react-values.

Targeted pattern scope​

This alias runs the exact implementation and options of no-unstable-react-values. It checks unstable values passed through component props and custom-hook boundaries.

What this rule reports​

It reports the same render-local object, array, function, JSX, instance, and optionally unknown values as the canonical rule.

Why this rule exists​

The alias preserves existing flat configurations during the v2 migration. New configurations should use the canonical name so they do not depend on a rule scheduled for removal.

❌ Incorrect​

function Search() {
 return <Results options={{ limit: 10 }} />;
}

✅ Correct​

function Search({ options }: { options: SearchOptions }) {
 return <Results options={options} />;
}

Deprecated​

This rule was deprecated in v2.0.0, remains available in v3, and is scheduled for removal in v4.0.0. It uses the same implementation, options, and diagnostics as the canonical rule. Rename the rule ID without changing its configuration:

import etcMisc from "eslint-plugin-etc-misc";

export default [
 {
  plugins: { "etc-misc": etcMisc },
  rules: {
   "etc-misc/require-usememo": "off",
   "etc-misc/no-unstable-react-values": "warn",
  },
 },
];

See no-unstable-react-values for the full behavior, options, and examples.

Behavior and migration notes​

The alias and canonical rule share one create implementation. Do not enable both IDs: doing so produces duplicate diagnostics. The alias is excluded from presets.

When not to use it​

Do not add this deprecated ID to a new configuration. Use no-unstable-react-values directly.
