Tasks

startTask() and task() can be used to mark all async operations during store initialization.

import { task } from 'nanostores'

onMount($post, () => {
  task(async () => {
    $post.set(await loadPost())
  })
})

You can wait for all ongoing tasks end in tests or SSR with await allTasks().

import { allTasks } from 'nanostores'

$post.listen(() => {}) // Move store to active mode to start data loading
await allTasks()

const html = ReactDOMServer.renderToString(<App />)
