Top 9 NPM Packages for Supercharging Your React.js Projects

Top 9 NPM Packages for Supercharging Your React.js Projects

Today, I’d like to share with you a selection of the top 9 NPM (Node Package Manager) packages that are commonly needed when working on React.js projects. These packages are widely recognized for their utility in React.js development. It’s important to note that the popularity of these packages can shift over time, so it’s a good practice to stay updated with the latest recommendations and developments in the React.js ecosystem.

1. React Router

React Router is a popular library for handling routing and navigation in React applications. It allows you to create single-page applications (SPAs) by defining routes and rendering different components based on the URL. Here’s an example of how to use React Router:

  1. First, you need to install React Router in your project:
npm install react-router-dom
  1. Next, you can create a basic example using React Router:
import React from 'react';
import { BrowserRouter as Router, Route, Link } from 'react-router-dom';

// Components for different pages
const Home = () => <h2>Home Page</h2>;
const About = () => <h2>About Page</h2>;
const Contact = () => <h2>Contact Page</h2>;

const App = () => {
  return (
            <Link to="/">Home</Link>
            <Link to="/about">About</Link>
            <Link to="/contact">Contact</Link>

      <Route path="/" exact component={Home} />
      <Route path="/about" component={About} />
      <Route path="/contact" component={Contact} />

export default App;

In this example:

  • We import necessary components and functions from react-router-dom.
  • We define three simple components: Home, About, and Contact, which represent different pages.
  • Inside the App component, we wrap everything in a Router component. The Router is the top-level component that provides routing functionality.
  • We create navigation links using the Link component. When a user clicks on these links, React Router handles the navigation without a full page reload.
  • We define routes using the Route component. Each Route maps a URL path to a component. The exact prop ensures that the / route only matches when the URL is exactly “/”.

Now, when you navigate to different URLs (e.g., “/”, “/about”, or “/contact”), React Router will render the corresponding components without refreshing the page. This is the basic usage of React Router for handling navigation in a React application.

2. Redux

Redux is an open-source JavaScript library commonly used with React for managing the state of an application. It provides a predictable state container and a set of rules for managing state changes. Redux is often employed in larger and more complex React applications to make state management more organized and maintainable.

Here are the core concepts of Redux:

  1. Store: The store is a single JavaScript object that holds the entire state of your application. It’s considered the single source of truth for the application’s data.

  2. Actions: Actions are plain JavaScript objects that represent events or user interactions. They describe what happened in your application and must have a type property that defines the type of action to be performed.

  3. Reducers: Reducers are pure functions that take the current state and an action as arguments and return a new state. They define how the state should change in response to an action. Reducers should not modify the existing state but create a new state object.

  4. Dispatch: Dispatch is a method provided by Redux to send actions to the store. When you dispatch an action, Redux invokes the appropriate reducer to update the state.

  5. Selectors: Selectors are functions used to extract specific pieces of data from the state. They help in accessing the state in a structured manner.

  6. Middleware: Middleware provides a way to extend the capabilities of Redux. It can intercept actions before they reach the reducer, allowing for tasks like logging, asynchronous operations, and more.

Redux follows a unidirectional data flow, which means that data flows in one direction through the application: action -> reducer -> store -> view. This strict data flow helps maintain a clear and predictable state management process.

Here’s a simplified example of how Redux might be set up in a React application:

// Define an action
const incrementCounter = () => ({
  type: 'INCREMENT',

// Define a reducer
const counterReducer = (state = 0, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return state + 1;
      return state;

// Create a Redux store
const { createStore } = Redux;
const store = createStore(counterReducer);

// Dispatch an action

// Get the current state
console.log(store.getState()); // Outputs: 1

In a real-world application, you would connect Redux to your React components using a library like react-redux to provide access to the store and automatically update components when the state changes. Redux is particularly beneficial in managing the state of larger and more complex applications, where tracking state changes becomes a crucial aspect of development.

3. Axios

Axios is a popular JavaScript library used in React (and other JavaScript environments) for making HTTP requests to web servers and interacting with APIs. It provides a simple and convenient way to send asynchronous HTTP requests and handle responses. Axios is commonly used in React applications to fetch data from a server, send data to a server, or perform other HTTP-related tasks.

Key features and benefits of Axios in React include:

  1. Promise-Based: Axios uses Promises, which makes it easy to work with asynchronous operations in a more readable and consistent manner. You can use .then() and .catch() to handle responses and errors.

  2. Support for Browsers and Node.js: Axios is versatile and can be used both in web browsers and server-side Node.js applications. This makes it a suitable choice for universal or isomorphic JavaScript applications.

  3. Automatic JSON Parsing: Axios automatically parses JSON responses, so you can work with JavaScript objects directly.

  4. Interceptors: Axios allows you to define request and response interceptors, which can be useful for adding global headers, handling authentication, or logging requests and responses.

  5. Concurrency Control: You can send multiple requests concurrently and handle them using Axios.

  6. Cancel Requests: Axios provides a built-in way to cancel requests, which can be helpful when dealing with components that unmount before a request is completed.

Here’s an example of how to use Axios in a React component to fetch data from an API:

import React, { useEffect, useState } from 'react';
import axios from 'axios';

const MyComponent = () => {
  const [data, setData] = useState([]);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    // Fetch data from an API
      .then(response => {
      .catch(error => {
        console.error('Error fetching data:', error);
  }, []);

  return (
      {loading ? (
      ) : (
          { => (
            <li key={}>{}</li>

export default MyComponent;

In this example:

  • We import Axios and use the axios.get() method to make a GET request to an API endpoint.
  • We handle the response using .then() to update the data state and set loading to false once the data is fetched.
  • In the component’s rendering, we conditionally display either a loading message or the fetched data based on the loading state.

Axios simplifies the process of making HTTP requests in React applications, and it’s widely used in the React ecosystem for handling data fetching and API interactions.

4. Styled-components

“styled-components” is a popular npm package for styling React components using a technique called “CSS-in-JS.” With “styled-components,” you can write CSS code as JavaScript template literals, allowing you to create and manage component-specific styles directly within your React components. This approach provides several benefits:

  1. Scoped Styles: Styles defined with “styled-components” are scoped to the component they are defined in. This means there’s no risk of style clashes between different components.

  2. Dynamic Styling: You can use JavaScript variables, props, and state to conditionally apply styles based on component logic and data.

  3. Improved Maintainability: Styles are co-located with the components they belong to, making it easier to understand and maintain your codebase.

  4. Auto-prefixing: “styled-components” automatically applies vendor prefixes to CSS properties, ensuring compatibility across different browsers.

  5. Server-Side Rendering (SSR) Support: It works well with server-side rendering, making it a suitable choice for universal React applications.

Here’s an example of how to use “styled-components” in a React component:

import React from 'react';
import styled from 'styled-components';

// Define a styled component
const Button = styled.button`
  background-color: #007bff;
  color: #fff;
  padding: 10px 20px;
  border: none;
  border-radius: 5px;
  cursor: pointer;

  &:hover {
    background-color: #0056b3;

const MyComponent = () => {
  return (
      <h1>Styled Button Example</h1>
      <Button>Click Me</Button>

export default MyComponent;

In this example:

  • We import the styled function from “styled-components” to create a styled component called Button.
  • The styles are defined within the backticks (`) using template literals. This syntax allows you to write CSS directly in your JavaScript code.
  • The Button component can be used like any other React component and will render a button with the specified styles.

Using “styled-components” can make your code more maintainable and modular, as styles are closely associated with the components that use them. It’s a popular choice in the React community for managing styles, and it provides a powerful way to create responsive and dynamic user interfaces.


5. Material-UI

Material-UI is a popular npm package for building user interfaces (UIs) in React applications using Google’s Material Design principles. It provides a set of pre-designed and customizable UI components, styles, and icons that adhere to the Material Design guidelines. Material-UI simplifies the process of creating attractive and responsive web applications with a consistent and modern look and feel.

Key features and benefits of Material-UI in React include:

  1. Ready-Made Components: Material-UI offers a wide range of pre-built components, including buttons, input fields, navigation drawers, modals, and more. These components are highly customizable and can be easily integrated into your application.

  2. Theming Support: Material-UI includes a robust theming system that allows you to customize the look and feel of your application to match your brand or design requirements. You can define custom color palettes, typography, and other styles.

  3. Responsive Design: Material-UI components are designed to work seamlessly on various screen sizes and devices, making it suitable for building responsive web applications.

  4. Accessibility: Material-UI prioritizes accessibility by following accessibility best practices, which ensures that your applications are usable by people with disabilities.

  5. Icons: It provides a set of Material Design icons that you can easily use in your components.

  6. Server-Side Rendering (SSR) Support: Material-UI is compatible with server-side rendering, making it suitable for universal React applications.

Here’s an example of how to use Material-UI components in a React application:


npm install @mui/material @emotion/react @emotion/styled


import React from 'react';
import Button from '@mui/material/Button';
import AppBar from '@mui/material/AppBar';
import Toolbar from '@mui/material/Toolbar';
import Typography from '@mui/material/Typography';

const MyComponent = () => {
  return (
      <AppBar position="static">
          <Typography variant="h6">Material-UI Example</Typography>
      <div style={{ padding: '20px' }}>
        <Typography variant="body1">
          Welcome to Material-UI!
        <Button variant="contained" color="primary">
          Click Me

export default MyComponent;

In this example:

  • We import Material-UI components such as Button, AppBar, Toolbar, and Typography from the @mui/material package.
  • We use these components to create a simple user interface, including an app bar with a title and a button.

Material-UI is a popular choice for building React applications with a modern and consistent design. It is well-documented and actively maintained, making it a reliable choice for developers who want to create visually appealing and responsive web applications in React.


6. Formik

Formik is a popular npm package used in React applications to simplify the process of building and managing forms. It provides a set of utilities and components for handling form validation, submission, and state management, making it easier to create robust and user-friendly forms in React.

Here are some key features and benefits of using Formik in React:

  1. Form State Management: Formik helps manage form state, including form values, touched fields, and validation errors. It abstracts the often tedious and error-prone aspects of form handling.

  2. Form Validation: Formik simplifies form validation by allowing you to define validation rules and error messages for each field. Validation is triggered automatically as users interact with the form.

  3. Form Submission: It provides an easy way to handle form submissions, including handling asynchronous requests, form submission status, and error handling.

  4. Field-Level Components: Formik integrates seamlessly with React components, enabling you to build custom form fields using standard React components.

  5. Render Prop Pattern: Formik follows the “render prop” pattern, which means you can render your form components as children of the <Formik> component and access form state and functions via render props.

  6. Integration with Yup: Formik works well with the Yup validation library, providing a powerful combination for defining complex validation schemas.

Here’s a simple example of using Formik in a React component:

import React from 'react';
import { Formik, Field, Form, ErrorMessage } from 'formik';
import * as Yup from 'yup';

const initialValues = {
  firstName: '',
  lastName: '',
  email: '',

const validationSchema = Yup.object().shape({
  firstName: Yup.string().required('First Name is required'),
  lastName: Yup.string().required('Last Name is required'),
  email: Yup.string().email('Invalid email').required('Email is required'),

const MyForm = () => {
  const handleSubmit = (values, actions) => {
    // Handle form submission, e.g., send data to a server

  return (
      {() => (
            <label htmlFor="firstName">First Name</label>
            <Field type="text" name="firstName" />
            <ErrorMessage name="firstName" component="div" />
            <label htmlFor="lastName">Last Name</label>
            <Field type="text" name="lastName" />
            <ErrorMessage name="lastName" component="div" />
            <label htmlFor="email">Email</label>
            <Field type="email" name="email" />
            <ErrorMessage name="email" component="div" />
            <button type="submit">Submit</button>

export default MyForm;

In this example:

  • We use Formik to manage the form state and validation.
  • The <Formik> component wraps the form and provides the necessary context for form handling.
  • We define the form fields using the <Field> component and specify their names and types.
  • Validation rules are defined using Yup’s validation schema.
  • When the form is submitted, the handleSubmit function is called, where you can handle form submission logic (e.g., sending data to a server).

Formik simplifies the process of working with forms in React, reducing boilerplate code and providing a structured approach to form handling and validation. It’s a popular choice for form management in React applications.


7. React-Query

React Query is an npm package used to manage, cache, and synchronize data fetching and state management in React applications. It simplifies complex data-fetching scenarios by providing a powerful and efficient way to interact with remote APIs, databases, or other data sources.

Key features and benefits of React Query include:

  1. Data Fetching: React Query provides hooks for fetching data, including useQuery for reading data and useMutation for handling data mutations. These hooks abstract away the complexities of making HTTP requests and managing data fetching states.

  2. Automatic Caching: React Query automatically caches fetched data, reducing the need for redundant requests to the server. Cached data is automatically invalidated and refetched when needed.

  3. Data Synchronization: It offers real-time data synchronization capabilities, ensuring that data stays up to date with minimal effort. You can use polling or WebSockets for real-time updates.

  4. Optimistic Updates: React Query allows you to perform optimistic updates, where the UI is updated optimistically before the server responds to a mutation. This provides a smoother user experience.

  5. Pagination and Infinite Scrolling: It provides built-in support for pagination and infinite scrolling, making it easy to handle large datasets.

  6. Server State Management: React Query can manage server state alongside local state, helping you keep track of data changes on the server.

  7. Custom Queries: You can define custom queries and mutations to interact with any data source, not just REST APIs. This makes it highly flexible.

  8. Devtools: React Query comes with a browser extension that provides a visual interface for debugging and inspecting the queries and mutations in your application.

Here’s a simple example of using React Query to fetch data in a React component:

import React from 'react';
import { useQuery } from 'react-query';

const fetchData = async () => {
  const response = await fetch('');
  const data = await response.json();
  return data;

const MyComponent = () => {
  const { data, isLoading, isError } = useQuery('myData', fetchData);

  if (isLoading) {
    return <p>Loading...</p>;

  if (isError) {
    return <p>Error fetching data</p>;

  return (
      <h1>Data from API</h1>
        { => (
          <li key={}>{}</li>

export default MyComponent;

In this example:

  • We import the useQuery hook from React Query to fetch data from an API using the fetchData function.
  • The useQuery hook manages the loading state and automatically caches the data for subsequent renders.
  • We handle loading and error states, ensuring a smooth user experience.

React Query is a powerful tool for managing data in React applications, and it’s particularly beneficial in scenarios where you need to handle complex data-fetching requirements, real-time updates, and caching. It simplifies data management and helps improve the performance of your applications.


8. Redux-Saga

A library for managing side effects in Redux applications. Redux-Saga is a middleware library for Redux, a popular state management library in React applications. Redux-Saga is used to manage side effects, such as asynchronous data fetching, API calls, and more, in a Redux-based application. It provides an alternative approach to handling side effects compared to the more common Redux Thunk middleware.

Key features and benefits of Redux-Saga include:

  1. Declarative Effects: Redux-Saga allows you to describe complex asynchronous operations (sagas) in a declarative and readable manner using generator functions. This makes it easy to follow and test your application’s side effect logic.

  2. Non-Blocking: Sagas run independently of your main application logic, ensuring that long-running tasks don’t block the main thread, which can improve the overall user experience.

  3. Cancellable Effects: You can cancel and abort side effects when they are no longer needed, helping to manage resource usage effectively.

  4. Error Handling: Redux-Saga provides clear error handling mechanisms for managing errors that occur during side effects. You can define how to handle errors and retry operations if necessary.

  5. Testability: Because sagas are pure generator functions, they are easy to test in isolation. You can mock external dependencies and test each step of a saga independently.

  6. Integration with Redux: Redux-Saga integrates seamlessly with Redux, allowing you to dispatch actions and update the Redux store based on the results of side effects.

  7. Complex Flows: It’s well-suited for managing complex control flows, including tasks like authentication, polling, and WebSocket communication.

Here’s a simple example of a Redux-Saga setup in a React application:

  1. First, you need to install Redux, Redux-Saga, and set up your Redux store:
npm install redux redux-saga
  1. Then, you can create a saga that listens for a specific action and performs an asynchronous operation:
// saga.js
import { put, takeEvery, all } from 'redux-saga/effects';

function* fetchData(action) {
  try {
    // Perform an asynchronous API call
    const data = yield fetch('/api/data').then(response => response.json());

    // Dispatch a success action with the fetched data
    yield put({ type: 'FETCH_DATA_SUCCESS', payload: data });
  } catch (error) {
    // Dispatch an error action on failure
    yield put({ type: 'FETCH_DATA_FAILURE', error });

function* watchFetchData() {
  yield takeEvery('FETCH_DATA_REQUEST', fetchData);

export default function* rootSaga() {
  yield all([watchFetchData()]);
  1. You also need to configure your Redux store to use Redux-Saga middleware:
// store.js
import { createStore, applyMiddleware } from 'redux';
import createSagaMiddleware from 'redux-saga';
import rootReducer from './reducers';
import rootSaga from './sagas';

const sagaMiddleware = createSagaMiddleware();

const store = createStore(

export default store;
  1. In your React components, you can dispatch actions to trigger the sagas:
// Component.js
import React, { useEffect } from 'react';
import { useDispatch, useSelector } from 'react-redux';

const Component = () => {
  const dispatch = useDispatch();
  const data = useSelector(state =>;

  useEffect(() => {
    // Dispatch an action to trigger the saga
    dispatch({ type: 'FETCH_DATA_REQUEST' });
  }, [dispatch]);

  return (
      {data.loading && <p>Loading...</p>}
      {data.error && <p>Error: {data.error.message}</p>}
      { && (
          { => (
            <li key={}>{}</li>

export default Component;

In this example:

  • We define a saga (fetchData) that listens for the 'FETCH_DATA_REQUEST' action, fetches data from an API, and dispatches success or failure actions accordingly.
  • The root saga (rootSaga) is composed of all the individual sagas.
  • In the Redux store configuration, we use createSagaMiddleware() to create the middleware and run the root saga.
  • In the React component, we dispatch the 'FETCH_DATA_REQUEST' action to trigger the saga when the component mounts.

Redux-Saga provides a powerful way to handle complex asynchronous logic in your React and Redux applications, making it a valuable choice for managing side effects and maintaining a clean separation of concerns in your codebase.


9. React Helmet

react-helmet is an npm package commonly used with React applications to manage the document head (e.g., <head>) of a web page. It allows you to dynamically update meta tags, title, and other elements within the document head based on the current state of your React application.

Here are some key features and benefits of using react-helmet:

  1. Dynamic Title and Meta Tags: With react-helmet, you can set and update the page title and meta tags (such as description, keywords, etc.) based on the current route or component’s state. This is particularly useful for improving SEO and social sharing.

  2. Server-Side Rendering (SSR) Support: react-helmet works well with server-side rendering, ensuring that the document head is properly populated with metadata on the server side before being sent to the client.

  3. Granular Control: You have granular control over the contents of the document head, allowing you to set different titles, meta tags, and other elements for different pages or components within your application.

  4. Component-Based: react-helmet is designed to work seamlessly with React components. You can include it in your components and update the document head based on the component’s state or props.

  5. Support for Favicon and Other Head Elements: It’s not limited to just title and meta tags; you can also use react-helmet to manage other head elements like link tags for stylesheets, favicon, or even script tags.

Here’s a basic example of how to use react-helmet in a React component:

import React from 'react';
import { Helmet } from 'react-helmet';

const MyComponent = () => {
  return (
        <title>My Page Title</title>
        <meta name="description" content="This is a description of my page." />
        <link rel="canonical" href="" />

      {/* Rest of your component */}
      <h1>Welcome to My Page</h1>
      {/* ... */}

export default MyComponent;

In this example:

  • We import the Helmet component from react-helmet and use it to set the title, description, and canonical URL of the page.
  • The contents of the Helmet component will be dynamically injected into the document head by react-helmet when the component is rendered.

This is a simplified example, but in a real-world application, you can use react-helmet to manage and update the document head based on the current route, user authentication status, or any other dynamic factors in your React application.

Overall, react-helmet is a valuable tool for managing the document head in React applications, ensuring that your web pages have the correct metadata and SEO-friendly content for optimal user experience and discoverability.
