When to use each

immer

Use Immer whenever you have deeply nested state updates that are painful to write immutably: Redux reducers, Zustand's set function, or React useState with complex objects. It's built into Redux Toolkit's createSlice, so you're probably already using it.

react-hook-form

Use React Hook Form for any form with more than 3-4 fields, especially if they have validation logic. It integrates well with Zod (via @hookform/resolvers/zod) for schema-based validation, giving you type-safe forms with runtime validation in a few lines.

When to skip each

immer

For flat, simple state (a counter, a boolean toggle), immer's overhead isn't worth it — just spread the object. Immer also has edge cases with classes, Maps, and Sets that require using enableMapSet() and enableAllPlugins().

react-hook-form

For very simple single-field forms (a search box, a newsletter signup), useState is less code. For highly dynamic forms where fields are added/removed programmatically, the useFieldArray API works but adds complexity — evaluate Formik for that use case.
