Access data from the server-side initial state API within apps.

npm install @nextcloud/initial-state --save

yarn add @nextcloud/initial-state

Check "Providing the initial state with PHP" for more details about initial state.

Note: loadState throws an Error if the key isn't found, hence you might want to wrap the call with a try block.

import { loadState } from '@nextcloud/initial-state'

const val = loadState('myapp', 'user_preference')

// Provide a fallback value to return when the state is not found
const valWithFallback = loadState('myapp', 'user_preference', 'no_preference')

You can provide a type anotation for result.

import { loadState } from '@nextcloud/initial-state'

interface UserPreference {
  refreshInterval: number
}

const val = loadState<UserPreference>('myapp', 'user_preference', {
  refreshInterval: 15_000
})
