Resolving the history.push is not a function Error in React with Redux Forms

When working with forms in React applications that utilize Redux and React Router, developers often face challenges with navigation and state management. One common issue is the error message: Unhandled Rejection (TypeError): history.push is not a function. This typically occurs when attempting to navigate users after form submission, particularly when using Redux forms. In this guide, we’ll break down why this error occurs and how to effectively resolve it.

The Problem: Understanding the Error

In your React application, particularly when using redux-form for managing form state, you may encounter this frustrating error during an action creator. This usually arises when you attempt to redirect a user to another route after successfully submitting a form. For example:

Upon successful form submission, the intention is to redirect the user to the /contacts route.

However, the action creator throws an error stating history.push is not a function, indicating that the history object is undefined at that point.

What Causes the Issue?

The root cause of this issue is simple: the history object is not automatically available in the action creator. While redux-form's handleSubmit function provides form values seamlessly, it does not pass additional parameters like history unless explicitly defined. Since history is essential for navigation, you need to ensure it is available where you need it.

The Solution: How to Pass the History Object

To resolve this issue, you need to modify the way the form submission function is structured in your form component. By introducing an intermediary function that includes both the form values and the history object, you can bypass the error and achieve the desired redirection.

Step-by-Step Guide to Fixing the Error

Define an Intermediary Submission Function

Instead of directly passing your action to handleSubmit, declare a separate function that takes form values and the history object as parameters:

Use the Intermediary Function in handleSubmit

Now, you can pass this newly created submission function to handleSubmit. Update your form's submit prop as follows:

Conclusion

By adjusting the way you manage form submissions and ensuring that the history object is correctly passed to your action creators, you can eliminate the history.push is not a function error. This allows for smooth navigation in your React application and an improved user experience. As always, when working with third-party libraries like redux-form and react-router, understanding how data flows through your components is key to successful implementations. Happy coding!
