Expo Adapter

Notes on Android

By default, Android requires https (including WebSocket connections) when communicating with a sync backend.

To allow for http / ws, you can run expo install expo-build-properties and add the following to your app.json (see here for more information):

{
  "expo": {
    "plugins": [
      "expo-build-properties",
      {
        "android": {
          "usesCleartextTraffic": true
        },
        "ios": {}
      }
    ]
  }
}

Resetting local persistence

When iterating locally you can ask the Expo adapter to drop the on-device state and eventlog databases before booting:

import { makePersistedAdapter } from '@livestore/adapter-expo'

const resetPersistence = process.env.EXPO_PUBLIC_LIVESTORE_RESET === 'true'

const adapter = makePersistedAdapter({
  storage: { subDirectory: 'dev' },
  resetPersistence,
})
