@hmans/use-const

Summary

useConst, a simple hook that allows you to define a contant value that will never change during the lifetime of the component.

import { useConst } from "@hmans/use-const"

const MyComponent = () => {
  const foo = useConst(() => new Foo())
  /* ... */
}

Motivation

Typically, you might use useMemo or useState for these things. useMemo doesn't give you a guarantee that it will never re-run its initializar function (which can be bad, depending on what kind of value you're dealing with), and useState adds state tracking overhead that sometimes is not needed.
