# Installation in bare React Native projects
|
|
|
|
For bare React Native projects, you must ensure that you have [installed and configured the `expo` package](https://docs.expo.dev/bare/installing-expo-modules/) before continuing.
|
|
|
|
### Add the package to your npm dependencies
|
|
|
|
```
|
|
expo install expo-constants
|
|
```
|
|
|
|
#### Monorepo Support
|
|
|
|
In a monorepo, the `expo-constants` package might be in a different folder than the native scripts are expecting. You can easily symlink the node module to your app's local `node_modules` folder by doing the following:
|
|
|
|
- Follow the setup instructions for [`expo-yarn-workspaces`](https://github.com/expo/expo/tree/main/packages/expo-yarn-workspaces).
|
|
- Add the following configuration to your app's `package.json`:
|
|
|
|
```json
|
|
{
|
|
"expo-yarn-workspaces": {
|
|
"symlinks": ["expo-constants"]
|
|
}
|
|
}
|
|
```
|
|
|
|
- Finally, run `yarn` in the app folder to create symlinks to `expo-constants` in your app's local `node_modules` folder.
