What's Changed

• feat!: React 19 by @CodyJasonBennett in https://github.com/pmndrs/react-nil/pull/19

This release adds support for React 19, and removes its own act export in favor of React.act.

Any augmentations or references to global JSX are now to be included in the react module. You can check out the React 19 changelog here.

import { useState, useEffect, act } from 'react'
import { render } from 'react-nil'

declare module 'react' {
  namespace JSX {
    interface IntrinsicElements {
      timestamp: Record<string, unknown>
    }
  }
}

function Test() {
  const [value, setValue] = useState(-1)
  useEffect(() => setValue(Date.now()), [])
  return <timestamp value={value} />
}

const container = await act(async () => render(<Test />))

// { type: 'timestamp', props: { value: number }, children: [] }
console.log(container.head)
