Hey 👋 did you check this from the docs? https://docs.reown.com/appkit/react-native/core/installation#create-babel-config-js

Thanks for the reply!
Our project is not using Expo — it’s a bare React Native CLI project.

Could you please clarify if the same babel.config.js setup applies to pure RN CLI as well, or provide a minimal example for non-Expo projects?

Thanks in advance!

@nickbvr The babel config should solve the import.meta issue on both expo and RN CLI. Can you try it?

[nickbvr]

I tried the suggested babel config in our project.

The project now builds without errors, but at runtime the app crashes during AppKit initialization with the following errors:

• Cannot convert undefined value to object
• Cannot read property 'appKit' of undefined
• AppKit: Failed to create instance - AppKit.ts:createAppKit TypeError: Cannot convert undefined value to object

This looks like import.meta is being transformed to undefined at runtime, so while the build passes, the runtime logic depending on import.meta breaks.

// babel.config.js
module.exports = {
  presets: [['babel-preset-expo', { unstable_transformImportMeta: true }]],
  plugins: ['react-native-worklets/plugin'],
};
