react-hooks-js/incompatible-library

Validates against usage of libraries which are incompatible with memoization (manual or automatic)

Validation prompt

Confirm the detector match and collect the required evidence before deciding whether an edit is warranted.

Fires on a hardcoded allowlist (maintained in facebook/react's DefaultModuleTypeProvider.ts) of APIs that use interior mutability and break memoization: currently react-hook-form's watch(), TanStack Table's useReactTable, and others.

Suppress when: you've already opted that file or component out of compilation via the 'use no memo' directive, or the API has shipped a memo-safe replacement since the list was published.

Evidence boundary

The diagnostic proves only that the detector’s modeled source pattern matched. It does not prove runtime impact, product intent, rendered failure, or that one remediation is correct.

Establish the environment, repository policy, exceptions, and required rendered or runtime evidence before deciding the occurrence.

Record one outcome:

• Confirmed failure: The required evidence establishes the violation.
• Rejected: A documented exception or false-positive predicate applies.
• Needs evidence: Named evidence can still be collected.
• Unavailable: Required evidence cannot be collected in this run.
• Waived with evidence: An authorized, scoped exception applies to an established failure.
• Observation: The review records an optional tradeoff without claiming a defect.

A waiver records its scope, authority, evidence, and review condition. It is not a pass or false positive.

Default severity is registry metadata. Use the occurrence’s JSON severity after repository configuration when ordering real findings.

Fix prompt

Apply this candidate correction only after the required evidence confirms the risk.

Swap for the library's memo-safe alternative when one exists: useWatch + control instead of watch for react-hook-form, the newer immutable-state hooks for TanStack Table. For libraries without a fix (MobX observer, etc.), add 'use no memo' as the first statement of the affected component or file so the Compiler skips it cleanly. File an issue upstream so the allowlist can grow. See https://react.dev/reference/eslint-plugin-react-hooks/lints/incompatible-library
