After installing this npm package, add the config plugin to the plugins array of your app.json or app.config.js. Then rebuild your app using a custom development client, as described in the "Adding custom native code" guide.

You also need to add the packaging options pick-first for android.

Example

In your app.json plugins array:

{
  "plugins": [
      [
        "@morrowdigital/watermelondb-expo-plugin"
      ],
      [
        "expo-build-properties",
        {
          "android": {
            "kotlinVersion": "1.6.10",
            "packagingOptions": {
              "pickFirst": [
                "**/libc++_shared.so"
              ]
            }
          }
        }
      ]
  ]
}

JSI support for Android

This plugin installs automatically JSI support for Android builds, as per WatermelonDB for Android instructions. If you wish to disable JSI support during build you may add the option in config plugin:

  [
    "@morrowdigital/watermelondb-expo-plugin",
    { "disableJsi": true }
  ]

Build errors with M1 architectures for simulators

There have been errors building with M1 architectures for simulators on iOS, with Error:

No such module 'ExpoModulesCore' 

See these discussions:

• https://github.com/morrowdigital/watermelondb-expo-plugin/issues/20
• https://github.com/morrowdigital/watermelondb-expo-plugin/issues/34
• https://github.com/facebook/react-native/issues/32704#issuecomment-1174458011

This plugin will NOT add the arm64 in Exlcuded_Archs, in SDK 50 builds:

'"EXCLUDED_ARCHS[sdk=iphonesimulator*]"'] = '"arm64"'

If you wish to add the above in configuration, you can add it with option:

  [
    "@morrowdigital/watermelondb-expo-plugin",
    { "excludeSimArch": true }
  ]
