AtomValue

The AtomValue component provides an interface similar to Jotai’s useAtomValue hook as props, allowing declarative usage.

props.atom

You can use Jotai’s atom as is.

import { AtomValue } from '@suspensive/jotai'
import { atom } from 'jotai'
 
const countAtom = atom(1)
 
const Example = () => {
  return (
    <AtomValue atom={countAtom}>{(count) => <>count: {count}</>}</AtomValue>
  )
}

For Async Atom, it delegates the pending state of the Promise to the parent Suspense until the Promise resolves.

import { AtomValue } from '@suspensive/jotai'
import { Suspense } from '@suspensive/react'
import { atom } from 'jotai'
 
const countAtom = atom(1)
const asyncDoubleCountAtom = atom(async (get) => {
  await delay(2000)
  return get(countAtom) * 2
})
 
const Example = () => (
  <Suspense fallback={'pending...'}>
    <AtomValue atom={asyncDoubleCountAtom}>
      {(count) => <>count: {count}</>}
    </AtomValue>
  </Suspense>
)

Motivation

Similar to <Atom/>, <AtomValue/> also does not clearly reveal which atoms are used internally in child components and whether they trigger Suspense.
