How to Build a Fancy Verification Code Component with React Custom Hooks?


Verification code components play a crucial role in modern web applications, ensuring secure access and transactions. With the power of React and custom hooks, we can create not only a functional verification code component but also an aesthetically pleasing one that enhances user experience. In this tutorial, we’ll guide you through the process of building a fancy verification code component using React and custom hooks, complete with animations and user-friendly styling.

Understanding React Custom Hooks

Before we dive into the specifics, let’s briefly discuss React custom hooks. Custom hooks are functions that allow us to extract component logic into reusable functions. They are an essential part of creating modular and maintainable React code.

The Basics of Verification Code Components

A verification code component is typically used to confirm the identity of a user, often sent via SMS or email. It consists of input fields where users enter the code they’ve received. Our goal is to take this functional concept and elevate it with visual appeal and smooth interaction.

Planning Our Fancy Verification Code Component

As we embark on this project, it’s essential to have a clear plan in mind. We envision a component with elegant animations, a clean layout, and immediate user feedback. Think about the features you’d like to implement: animations on input focus, real-time validation, and a responsive design.

Setting Up the React Project

First things first, let’s set up our project. You can either create a new React project or integrate this component into an existing one. Ensure you have Node.js and npm installed, and initialize your project.

Creating the Skeleton of the Verification Code Component

Our verification code component’s skeleton consists of input fields where users will enter the code. Using JSX, set up the basic structure of the component. We’ll refine this as we progress.

Implementing the Custom Hook

Now comes the exciting part—creating our custom hook to manage the verification code logic. We’ll define a hook that handles input changes, automatically focuses on the next input, and triggers validation.

Adding Stylish Animations

To give our verification code component a touch of elegance, animations are a must. Explore animation libraries compatible with React, such as Framer Motion or React Spring. Apply animations to the input fields, making the component engaging and user-friendly.

Styling Our Fancy Verification Code Component

A visually appealing design is key to capturing users’ attention. Depending on your preference, you can use CSS-in-JS libraries like styled-components or external stylesheets. Craft a design that aligns with your application’s aesthetics while ensuring readability.

User Interaction and Feedback

The interaction between users and our component should feel intuitive. Provide instant feedback when users enter a code, and highlight the active input field. These small touches contribute to a seamless user experience.

Handling Errors and Resending Codes

As users enter verification codes, errors are inevitable. Implement error handling to notify users of incorrect codes and guide them in rectifying the issue. Additionally, consider adding a feature to resend verification codes if needed.

Testing the Component

Testing is a critical phase of development. Write unit tests using libraries like Jest and React Testing Library. Ensure that the component behaves as expected, handling input changes, validations, and animations accurately.

Optimizing for Accessibility

Accessibility is paramount. Enhance your component’s accessibility by adding appropriate aria labels and roles. Consider users who rely on screen readers, and ensure they can seamlessly navigate and interact with the verification code component.

Deploying the Fancy Verification Code Component

With development complete, it’s time to deploy. Prepare the component for deployment by optimizing its production build. Choose a deployment method that suits your project, whether it’s a standalone component or part of a larger application.


In this tutorial, we’ve embarked on a journey to create a fancy verification code component using React custom hooks. We’ve explored the process step by step, from setting up the project to enhancing user interaction with animations and styling. Remember, React custom hooks empower us to build reusable UI elements that not only serve their functional purpose but also enrich the user experience.


  1. How do custom hooks improve code reusability in React? Custom hooks allow us to extract and reuse component logic, reducing code duplication and enhancing maintainability.
  2. Can I use CSS modules for styling the verification code component? Absolutely! CSS modules offer a modular approach to styling and work seamlessly with React components.
  3. Is it possible to customize the animation styles according to my project’s design? Yes, you can customize animation styles to align with your project’s design language using animation libraries like Framer Motion.
  4. What’s the best way to handle server-side verification of the entered codes? Server-side verification involves sending the entered code to the server and comparing it to the expected value. Implement a secure API endpoint for this purpose.
  5. Are there any security considerations when building verification components? Security is crucial. Avoid exposing sensitive information in the client-side code, and implement measures to prevent brute-force attacks on verification codes.
