How to Pass Function Component Context as Parameter in React: A Guide to Using useSnackbar Hook

In the realm of React development, managing notifications within your components can sometimes be tricky, especially when using hooks. One common issue developers encounter is how to effectively utilize the useSnackbar hook from the notistack library within a functional component. This post aims to clarify this dilemma and provide a simple solution.

The Challenge

You might have come across the limitation stating that "Hooks can only be called inside the body of a function component." If you've attempted to create a wrapper function around useSnackbar, you likely found that passing the component context or using this is ineffective. This limitation can hinder the way you want to structure your notification logic.

Suppose you want to create a user-friendly interface for notifications, such as alert, warn, info, and success. Here's what you might have tried previously:

The above code will result in an error since it's trying to execute a hook outside its proper context.

The Solution: Using a Custom Hook

The solution lies in creating a custom hook that integrates the useSnackbar hook into its body. Here’s how you can structure it effectively:

Step 1: Creating the Custom Hook

Let's create a custom hook called useToast that encapsulates the useSnackbar logic:

Step 2: Integrating the Hook in Your Component

Now, you can utilize this useToast custom hook within any functional component. Here's an example:

Benefits of This Approach

Clean Separation: The notification logic is encapsulated within a custom hook, making your components cleaner and more focused.

Reusability: You can use the useToast hook in any component throughout your application without repeating code.

Flexibility: By adjusting the configuration in toastOptions, you can easily customize the appearance and behavior of your notifications.

Conclusion

By creating a custom hook, you can effectively bypass the limitation of using useSnackbar outside of a function component. This approach not only simplifies your code but also enhances maintainability and reusability.

Now, you can confidently create a notification system in your React application without the hassle of managing component context directly. Happy coding!
