useInsertionEffect

Under Construction

This section is incomplete, please see the old docs for useInsertionEffect.

The signateure is identical to useEffect, but it fires synchronously before all DOM mutations. Use this to inject styles into the DOM before reading layout in useLayoutEffect. Since this hook is limited in scope, this hook does not have access to refs and cannot schedule updates.

useInsertionEffect(didUpdate);

Atención

useInsertionEffect should be limited to css-in-js library authors. Prefer useEffect or useLayoutEffect instead.
