## Development

```
nvm install
nvm use
nvm alias default $(nvm version) # optional
```

You can run the following commands to ensure that you are running the correct `node` and `npm` versions.

```
node -v # expected: v18.x.x (should match .nvmrc)
npm -v  # expected: 8.x.x
```

```
npm run webpack
```

The file is generated in **native**/**ios**/v4-native-client.js Pending: Different configurations may be needed to generate JS for Android app
