solid-persistent

SolidJS utility to create persistent components that keep their state and elements cached when removed from the DOM.

Features

• Persists both JavaScript state and HTML elements
• Supports SSR

Usage

Import the createPersistent utility and pass your component to it. Make sure to call the utility inside a component that doesn't unmount. Then use the returned Accessor in your JSX where it can unmount.

import createList from 'solid-list'

const PersistedDialogContent = () => {
  const persistedContent = createPersistent(() => {
    return <input />
  })

  return (
  <Dialog>
      <Dialog.Trigger>
        Open
      </Dialog.Trigger>
      <Dialog.Portal>
        <Dialog.Content>
          {persistedContent()}
        </Dialog.Content>
      </Dialog.Portal>
    </Dialog>
  )
}
