Troubleshooting “Invalid Hook Call” Error when Using Hooks in Custom React Component Library | A Guide to Fix Duplicate React Libraries

Can’t Use Hooks with my React Component Library: Invariant Violation – Invalid Hook Call

If you’ve been working on creating your own React Component Library and are running into issues with using hooks, you’re not alone. One common error message you may encounter is the “Hooks can only be called inside the body of a function component” warning. In this blog post, we’ll dive into the possible causes of this error and explore some potential solutions to get your hooks working seamlessly with your component library.

Possible Causes of the Invalid Hook Call Error

When encountering the “Invalid Hook Call” error, there could be several reasons behind it. Let’s explore some of the common causes:

1. Mismatching Versions of React and React DOM: Ensure that you have the latest versions of both React and React DOM installed in your project. Verify this by running the command npm i react@latest react-dom@latest.
2. Breaking the Rules of Hooks: Review your usage of hooks and make sure they are being called inside the body of a function component, not within any conditional statements or nested functions.
3. Duplicate React Packages: When using npm link to test your library, it can cause conflicts between the React packages installed in your library and the app project. To fix this, you can try linking the application’s React copy to your library by running the command npm link ../myapp/node_modules/react.
4. Webpack Configuration Issues: If you are using a custom webpack configuration, ensure that the resolve alias is set correctly to point to the React package in your app’s node_modules folder. This can be done by adding the following code to your webpack.config.js file:

resolve: {
  ...
  alias: {
    // Needed when library is linked via `npm link` to app
    react: path.resolve('./node_modules/react')
  }
}

Testing with Create-React-App and Compatibility

If you are encountering this error when using create-react-app, you can add the library as a dependency and import the provided Test component without any compatibility issues.

However, if you are using older versions of React in your app that are not compatible with hooks, you may face errors. Ensure your app’s React version is up to date to make full use of hooks.

Conclusion

Working on your own React Component Library can be an exciting endeavor, but running into errors, such as the “Invalid Hook Call” warning, can be frustrating. By following the troubleshooting steps outlined in this blog post, you should be able to resolve the issue and get your hooks working smoothly with your component library.

Remember to check for mismatching versions of React and React DOM, adhere to the Rules of Hooks, resolve any duplicate React package issues, and ensure your webpack configuration is properly set up.

With the provided solutions and guidance, you should now be able to overcome the “Invalid Hook Call” error and proceed with building your React Component Library without any hindrances!
