How to Implement a Stepper Component in React App

In this tutorial, we will discuss several ways to add stepper components to your React apps with practical examples. The several available methods for creating stepper components in React apps.

Web developers develop web application interfaces with various UI elements, such as buttons, tabs, sliders, toggle buttons, and dropdowns. In some scenarios, these include wizard-like flows with several steps, such as in web apps that let users make a reservation: designers typically decompose the entire workflow into several steps, such as entering user details, making a payment, and receiving the booking confirmation. Then, they indicate the progress through the list of steps in a separate section.

A basic stepper component

These steps-based flow indicators are known as stepper components. A stepper component typically visualizes several steps and indicates the current progress by highlighting already completed steps. A stepper component is usually responsible for displaying the workflow progress, so we often need to switch form segments programmatically.

In this tutorial, I’ll explain several ways to add stepper components to your React apps with practical examples.

Ways to implement a stepper component in React

In this section, we’ll check out the available stepper component development options and discuss when to use each!

Using a library for adding steppers is a good choice if you don’t use a fully-featured UI kit or don’t want to build a stepper widget from scratch. The following popular stepper libraries offer pre-developed, customizable React components:

Using react-stepper-horizontal

react-stepper-horizontal is a library that lets you create stepper components with a pre-developed, pre-styled Stepper component. This npm module was initially released in 2016 and offers several props to control the component behavior and styling.

This library’s GitHub repository doesn’t show much development activity, but it is highly usable in React apps because of its complete features and customizability.

Using react-form-stepper

react-form-stepper is an alternative to the react-stepper-horizontal library and offers a Material-inspired, pre-developed Stepper component for React developers. This library was released in 2019 and has an actively maintained GitHub repository.

This package offers almost all customization features, similar to the react-stepper-horizontal package. Additionally, it offers some modern features like HOC (higher-order components)-based step definitions.

Importing stepper components from UI kits

Many React developers use UI kits to develop their apps because UI kits offer all the generic components they need, so they don’t need to look for multiple-dependency libraries. Most modern React developers use MUI, React Bootstrap, or Prime React-like, fully-featured UI kits instead of writing their own UI elements. Most UI kits offer pre-developed stepper components, so we don’t need to install a dedicated stepper library if we use a fully-featured UI kit.

Building a stepper component from scratch

External packages increase your app bundle size (you can calculate this using BundlePhobia), so adding a third-party package for every development requirement isn’t always a good choice. Also, third-party packages may not completely fulfill your design requirements and may bring features that you don’t even use. Writing your own stepper component is also an option by including only the required features.
Let’s start creating stepper components with the above methods!

Creating stepper components with react-stepper-horizontal

Now, let’s make our first stepper component with the react-stepper-horizontal package, which offers a customizable, pre-developed Stepper component. First, create a new React project with Create React App, as follows:

npx create-react-app react-steppers-demo
cd react-steppers-demo

Next, install the stepper component library:

npm install react-stepper-horizontal
# --- or ---
yarn add react-stepper-horizontal

Creating a basic stepper component

Let’s create a basic stepper with this library. In this example, we’ll visualize a fixed, pre-defined set of steps for demonstration purposes. Add the following code to your App.js file:

import Stepper from 'react-stepper-horizontal';
import './App.css';

function App() {
  const steps = [
    { title: 'User details' },
    { title: 'Payment' },
    { title: 'Booking confirmation' },
  ];
  const activeStep = 1;

  return (
    <div>
      <Stepper
        steps={steps}
        activeStep={activeStep}/>
    </div>
  );
}

export default App;

Run your app and check the web browser. You’ll see a pre-styled stepper component with three steps, as we defined in the source file:

A basic stepper component

Here, we rendered a basic stepper by providing three steps via the steps prop and highlighting the finished steps by setting the activeStep prop. Steps one and two are marked as done because activeStep is 1 (index 1 refers to the second element, since the index starts from 0).

Using dynamic sections with the stepper component

Now we can dynamically switch form segments based on the active step to make the app more interactive. Use the following code in your App.js file:

import React, { useState } from 'react';
import Stepper from 'react-stepper-horizontal';
import './App.css';

function UserDetails() {
  return <h2>User details</h2>;
}

function Payment() {
  return <h2>Payment information</h2>;
}

function Confirmation() {
  return <h2>Booking is confirmed</h2>;
}

function App() {
  const [ activeStep, setActiveStep ] = useState(0);

  const steps = [
    { title: 'User details' },
    { title: 'Payment' },
    { title: 'Booking confirmation' },
  ];

  function getSectionComponent() {
    switch(activeStep) {
      case 0: return <UserDetails/>;
      case 1: return <Payment/>;
      case 2: return <Confirmation/>;
      default: return null;
    }
  }

  return (
    <div>
      <Stepper
        steps={steps}
        activeStep={activeStep}/>
      <div style={{padding: '20px'}}>
        { getSectionComponent()  }
        { (activeStep !== 0 && activeStep !== steps.length - 1)
            && <button onClick={ () => setActiveStep(activeStep - 1) }>Previous</button>
        }
        { activeStep !== steps.length - 1
          && <button onClick={ () => setActiveStep(activeStep + 1) }>Next</button>
        }
      </div>
    </div>
  );
}

export default App;

Here, we store the current step index with the activeStep state field and use the setActiveStep function to change the current step. The getSectionComponent function helps us to render a form component based on the current step.

Users can switch steps by clicking on the next and previous buttons. Look at the following preview:

This library lets you attach click handlers to each step. For example, the following setup helps you navigate between steps by clicking the completed steps:

const steps = [
  { title: 'User details', onClick: () => setActiveStep(0) },
  { title: 'Payment', onClick: () => setActiveStep(1) },
  { title: 'Booking confirmation', onClick: () => setActiveStep(2) },
];

Customizing styles

In the previous example, we didn’t use any custom styles for the stepper component, so the library used the default blue color appearance for the stepper component.

The Stepper component accepts several props for style configuration. Let’s use those props and customize styles in the stepper component. We’ll create a dark-color theme for our sample app.

First, activate the dark-color theme by adding the following CSS into your App.css:

.container {
  height: 100vh;
  background: #111;
  color: #eee;
}

Next, implement a new wrapper component for the customized step and use it as follows in App.js:

function CustomStepper(props) {
  return (
    <Stepper
      { ...props }
      activeColor="#ffd813"
      defaultColor="#eee"
      completeColor="#ffbd13"
      activeTitleColor="#fff"
      completeTitleColor="#eee"
      defaultTitleColor="#bbb"
      circleFontColor="#000"
      completeBarColor="#ffbd13"/>
  );
}

function App() {
  const [ activeStep, setActiveStep ] = useState(0);

  const steps = [
    { title: 'User details' },
    { title: 'Payment' },
    { title: 'Booking confirmation' },
  ];

  function getSectionComponent() {
    switch(activeStep) {
      case 0: return <UserDetails/>;
      case 1: return <Payment/>;
      case 2: return <Confirmation/>;
      default: return null;
    }
  }

  return (
    <div className="container">
      <CustomStepper
        steps={steps}
        activeStep={activeStep}/>
      <div style={{padding: '20px'}}>
        { getSectionComponent()  }
        { (activeStep !== 0 && activeStep !== steps.length - 1)
            && <button onClick={ () => setActiveStep(activeStep - 1) }>Previous</button>
        }
        { activeStep !== steps.length - 1
          && <button onClick={ () => setActiveStep(activeStep + 1) }>Next</button>
        }
      </div>
    </div>
  );
}

Here, we’ve created a custom stepper by setting various props in the CustomStepper component implementation:

<Stepper
  { ...props }
  activeColor="#ffd813"
  defaultColor="#eee"
  completeColor="#ffbd13"
  activeTitleColor="#fff"
  completeTitleColor="#eee"
  defaultTitleColor="#bbb"
  circleFontColor="#000"
  completeBarColor="#ffbd13"/>

Once you add the above code updates, you’ll see the following result:

This library also lets you use custom opacities, margins, and stepper-bar styles. See all supported props in the official API documentation.

Creating stepper components with react-form-stepper

The react-form-stepper package is a modern alternative to the react-stepper-horizontal package. Its API is more structured than the react-stepper-horizontal package, but offers almost the same feature set.

Let’s get started by installing the new library as follows on the same React project we’ve used before:

npm install react-form-stepper
# --- or ---
yarn add react-form-stepper

Next, add the following code to your App.js file to create a basic stepper. Make sure to remove the dark theme CSS from your App.css:

import { Stepper } from 'react-form-stepper';
import './App.css';

function App() {
  const steps = [
    { label: 'User details' },
    { label: 'Payment' },
    { label: 'Booking confirmation' },
  ];
  const activeStep = 1;

  return (
    <div>
      <Stepper
        steps={steps}
        activeStep={activeStep}/>
    </div>
  );
}

export default App;

We’ve created a read-only, static stepper component by using the steps and activeStep props.

Run the app. You’ll see a stepper component with a default, Material-like styling, as shown in the following preview:

This library offers another coding style for constructing stepper components. For example, we can create the previous stepper in the following way:

import { Stepper, Step } from 'react-form-stepper';
import './App.css';

function App() {
  const activeStep = 1;

  return (
    <div>
      <Stepper
        activeStep={activeStep}>
        <Step label="User details"/>
        <Step label="Payment"/>
        <Step label="Booking confirmation"/>
      </Stepper>
    </div>
  );
}

export default App;

Here, we used Stepper, a Higher-Order Component (HOC), and Step components as children. You can use either the steps prop or the HOC coding style according to your preference.

Using dynamic sections with the stepper component

We can dynamically switch form components based on the active step to make the app more interactive. Use the following code in your App.js file:

import React, { useState } from 'react';
import { Stepper } from 'react-form-stepper';
import './App.css';

function UserDetails() {
  return <h2>User details</h2>;
}

function Payment() {
  return <h2>Payment information</h2>;
}

function Confirmation() {
  return <h2>Booking is confirmed</h2>;
}

function App() {
  const [ activeStep, setActiveStep ] = useState(0);

  const steps = [
    { label: 'User details' },
    { label: 'Payment' },
    { label: 'Booking confirmation' },
  ];

  function getSectionComponent() {
    switch(activeStep) {
      case 0: return <UserDetails/>;
      case 1: return <Payment/>;
      case 2: return <Confirmation/>;
      default: return null;
    }
  }

  return (
    <div>
      <Stepper
        steps={steps}
        activeStep={activeStep}/>
      <div style={{padding: '20px'}}>
        { getSectionComponent()  }
        { (activeStep !== 0 && activeStep !== steps.length - 1)
            && <button onClick={ () => setActiveStep(activeStep - 1) }>Previous</button>
        }
        { activeStep !== steps.length - 1
          && <button onClick={ () => setActiveStep(activeStep + 1) }>Next</button>
        }
      </div>
    </div>
  );
}

export default App;

The above code implements navigation buttons to switch the active step as we implemented for the react-stepper-horizontal example before. The above code will work as follows:

You can attach a click handler to each completed step node, and enable navigation support in the stepper component as follows:

const steps = [
  { label: 'User details', onClick: () => setActiveStep(0) },
  { label: 'Payment', onClick: () => setActiveStep(1) },
  { label: 'Booking confirmation', onClick: () => setActiveStep(2) },
];

Creating custom styles

Earlier, the library rendered a default stepper component because we didn’t apply custom styles. This library lets you customize the component appearance via props. Let’s check the supported styling props by implementing a dark-color theme.

First, activate a dark-color theme by using the following CSS in your App.css:

.container {
  height: 100vh;
  background: #111;
  color: #eee;
}

Next, use the following component implementations in your App.js file:

function CustomStepper(props) {
  return (
    <Stepper
      { ...props }
      connectorStateColors={true}
      connectorStyleConfig={{
        completedColor: '#ffbd13',
        activeColor: '#ffbd13',
        disabledColor: '#eee'
      }}
      styleConfig={{
        activeBgColor: '#ffd813',
        completedBgColor: '#ffbd13',
        inactiveBgColor: '#eee',
        activeTextColor: '#111',
        completedTextColor: '#222',
        inactiveTextColor: '#444'
      }}
      />
  );
}

function App() {
  const [ activeStep, setActiveStep ] = useState(0);

  const steps = [
    { label: 'User details' },
    { label: 'Payment' },
    { label: 'Booking confirmation' },
  ];

  function getSectionComponent() {
    switch(activeStep) {
      case 0: return <UserDetails/>;
      case 1: return <Payment/>;
      case 2: return <Confirmation/>;
      default: return null;
    }
  }

  return (
    <div className="container">
      <CustomStepper
        steps={steps}
        activeStep={activeStep}/>
      <div style={{padding: '20px'}}>
        { getSectionComponent()  }
        { (activeStep !== 0 && activeStep !== steps.length - 1)
            && <button onClick={ () => setActiveStep(activeStep - 1) }>Previous</button>
        }
        { activeStep !== steps.length - 1
          && <button onClick={ () => setActiveStep(activeStep + 1) }>Next</button>
        }
      </div>
    </div>
  );
}

The above code implements a custom, dark-theme-ready stepper component via the CustomStepper wrapper component. Run your app and check the web browser. You’ll see a custom stepper component as follows:

This library lets you customize the node connectors’ thickness, node border-radius, and node content via component props. See all supported props from the official API documentation.

Using stepper components from UI kits

Popular React UI kits offer pre-developed, pre-styled stepper components, so you don’t need separate third-party libraries if you use a UI kit that provides a stepper component. The following React UI kits come with beautiful, fully-featured stepper components:

MUI

MUI offers the Stepper component for adding steppers to your React apps. The MUI stepper offers the following step and stepper types:

  • Types of steps: editable, non-editable, mobile, optional
  • Types of steppers: horizontal, vertical, linear, non-linear

MUI stepper comes with several sub-components and props for customization purposes. You can check the official API documentation to learn more. You can also see a live demo on CodeSandbox:

Prime React

Prime React steps preview

Prime React steps preview

Prime React offers the Steps component for creating stepper components. It provides a basic stepper component and an interactive one where users can navigate among steps by clicking on each node. It also comes with various props for customization purposes.

You can browse API documentation from the official website and see this component live on CodeSandbox:

Creating a stepper component from scratch

If you need a minimal stepper, you don’t need to migrate to a large React UI kit or use a fully-featured stepper component library. Creating a shareable, minimal stepper component with React Hooks and some CSS is so easy and not so time-consuming.

I added this example’s source into a GitHub repository, so you can clone it into your computer to get started:

git clone https://github.com/codezri/react-stepper-minimal.git

Install dependencies with the following command:

npm install 
# --- or ---
yarn install

Next, run the React app and see it on your web browser:

npm start 
# --- or ---
yarn start

Once you run the app, you’ll see the following result:

A stepper component built from scratch

A stepper component built from scratch

This minimal stepper component has the following features:

  • Accepts steps as a string array and activeStep as an integer for rendering the stepper component based on arbitrary steps
  • Renders indices in circles based on steps and indicates completed, current, and inactive steps, with different styles accordingly
  • Renders and styles connector lines based on the current step
  • Changes the width and node positions adaptively according to the device resolution

Let’s understand how it works.

Look at the Stepper component implementation below. It constructs the step elements from the steps prop as follows:

steps.map((label, index) =>
  <div className={getStepClasses(index)} key={index}>
    <div><div className="circle">{index + 1}</div></div>
    <div className="label">{label}</div>
    { index < steps.length - 1 && <div className="line"></div> }
  </div>
)

We used the getStepClass function to dynamically set a CSS class to style steps based on the active step. For example, if a particular step’s index is the active step index, we use the step-active CSS class:

function getStepClasses(step) {
  let cls = 'step';
  if(activeStep === step) {
    cls += ' step-active';
  }
// ----

Each step element has a circle with the step number, label, and connector line. In App.css, we’ve styled these as divs:

/* ---- */
.step-done .circle {
  background: #236ee8;
  color: #eee;
}

.step-inactive .circle {
  background: #bbb;
  color: #000;
}

.step-active .label {
  color: #000;
}
/* ---- */

This stepper component is so minimal and implements all the basic features that a generic web app needs. You can copy-paste this implementation and extend it as you wish. If your step element rendering logic grows complex, you can refactor the Stepper component by separating step-related code into a new component called Step.

Conclusion

In this tutorial, we discussed several available methods for creating stepper components in React apps. The react-progress-stepper package lets you create animated steppers with progress bars. react-stepper-js offers a minimal pre-developed stepper component.

As discussed, you can implement your own stepper for your project and publish it to the npm registry as an open-source project for other developers to use. Importing a stepper component from a popular UI kit is another productive approach.
