Using React Hooks in Event Handlers: A Step-by-Step Guide (2026)

React Hooks have revolutionized how we manage state and lifecycle events in React components. This guide will walk you through using a custom hook, specifically within event handlers, to manage state in a React application. We'll focus on a practical example using Material UI Tabs and a custom hook, useTab, to dynamically change the tab ID based on user interaction.

Key Takeaways

• Learn to use custom React hooks within event handlers.
• Understand how to manage state changes in a React component.
• Implement a custom hook for reusability across components.
• Utilize Material UI's Tabs with React hooks for dynamic UI updates.

Introduction

React hooks provide a powerful way to utilize state and lifecycle features in functional components. By using hooks, you can streamline your components and make them more readable and manageable. However, using hooks inside event handlers can sometimes be confusing for beginners. This tutorial aims to clear up that confusion by showing you how to integrate hooks effectively within event-driven functions.

In this tutorial, we will create a simple React application using Material UI Tabs. We'll implement a custom hook called useTab that allows you to switch between tabs and demonstrate how to invoke this hook within an event handler.

Prerequisites

• Basic knowledge of React and JavaScript ES6.
• Experience with React Hooks like useState and useEffect.
• Familiarity with Material UI library.
• Node.js and npm installed on your machine.

Step 1: Set Up the React Application

First, ensure that you have Node.js and npm installed. You can set up a new React application using Create React App by executing the following command:

npx create-react-app material-ui-tabs-example

Once the setup is complete, navigate to the project directory:

cd material-ui-tabs-example

Install Material UI components:

npm install @material-ui/core @material-ui/icons

Step 2: Create the Custom Hook useTab

In the src/hooks directory, create a new file called tab.js and add the following code:

import { useState } from 'react';

export const useTab = (initialTab = 0) => {
  const [activeTab, setActiveTab] = useState(initialTab);

  const changeTab = (tabIndex) => {
    setActiveTab(tabIndex);
  };

  return { activeTab, changeTab };
};

This custom hook manages the active tab state and provides a function to change the current tab.

Step 3: Implement the ProductsNav Component

In the src directory, create a new file called ProductsNav.js and add the following code:

import React from 'react';
import AppBar from '@material-ui/core/AppBar';
import Tabs from '@material-ui/core/Tabs';
import Tab from '@material-ui/core/Tab';
import { useTab } from './hooks/tab';

const ProductsNav = () => {
  const { activeTab, changeTab } = useTab();

  const handleChange = (event, newValue) => {
    changeTab(newValue);
  };

  return (
    
      
        
        
        
      
    
  );
};

export default ProductsNav;

The ProductsNav component uses the useTab hook to manage the state of the active tab. The handleChange function is an event handler that calls changeTab when a new tab is selected.

Step 4: Integrate the ProductsNav Component

In the src/App.js file, replace the contents with:

import React from 'react';
import ProductsNav from './ProductsNav';

function App() {
  return (
    
      
    
  );
}

export default App;

This will render the ProductsNav component within your application, allowing you to switch tabs using the custom hook.

Common Errors/Troubleshooting

• Error: Hook called outside the function component: Ensure your hooks are called within a function component or a custom hook.
• Tabs not switching: Verify the event handler handleChange is correctly passing the tab index to changeTab.
• Material UI components not rendering: Check that you have installed the Material UI library correctly and imported the necessary components.

Frequently Asked Questions

Why can't I use hooks in regular functions?

Hooks can only be called at the top level of a React function component or a custom hook to preserve the state across re-renders.

Can I use hooks with class components?

No, hooks are designed for function components. For class components, use lifecycle methods.

Why is my hook not updating state?

Ensure that the state update function is being called correctly within an event handler and that the component re-renders to reflect changes.
