React useful libraries part 2

Introduction:

React is a powerful JavaScript library for building user interfaces, and its ecosystem is filled with various libraries that can enhance your development experience. In this blog post, we will explore five essential React libraries and provide basic examples to demonstrate their functionalities. These libraries will help you streamline your development process and create more efficient and feature-rich React applications.

React Hook Form

React Hook Form is a lightweight library for handling form validation and submission in React. It simplifies form management by providing a declarative API and intuitive hooks. Here's a basic example of using React Hook Form:

import { useForm } from 'react-hook-form';
 
const MyForm = () => {
 
    const { register, handleSubmit, errors } = useForm();
    const onSubmit = (data) => {
        // form data
        console.log(data);
    };
    return (
        <form onSubmit={handleSubmit(onSubmit)}>
            <input type="text" name="username" ref={register({ required: true })} />
            {errors.username && <span>This field is required</span>}
            <input type="password" name="password" ref={register({ required: true })} />
            {errors.password && <span>This field is required</span>}
            <button type="submit">Submit</button>
        </form>
    );
 
};
 

In the above example, we use the useForm hook to initialize the form and obtain functions like register for registering form inputs, handleSubmit for handling form submission, and errors for displaying validation errors. React Hook Form simplifies the process of handling form inputs, validation rules, and form submission.

React Toastify

React Toastify is a notification library that provides an easy way to display toast notifications in your React application. Toast notifications are small pop-up messages that inform users about events, errors, or important updates. Here's a basic example of using React Toastify:

 
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
const MyComponent = () => {
    const notify = () => {
        // run toast success
        toast.success('Hello, world!');
    };
 
    return (
        <div>
            <button onClick={notify}>Show Toast</button>
            <ToastContainer />
        </div>
    );
};

In the above example, we import the ToastContainer and toast components from React Toastify. Clicking the "Show Toast" button triggers a success toast notification. React Toastify provides various options for customizing the appearance and behavior of toast notifications.

React Modal

React Modal is a library that allows you to create modal dialogs in your React applications. Modals are commonly used to display additional content or capture user input without navigating away from the current page. Here's a basic example of using React Modal:

import React, { useState } from 'react';
import Modal from 'react-modal';
 
const MyComponent = () => {
    const [modalIsOpen, setModalIsOpen] = useState(false);
 
    const openModal = () => {
        setModalIsOpen(true);
    };
    const closeModal = () => {
        setModalIsOpen(false);
    };
    return (
        <div>
            <button onClick={openModal}>Open Modal</button>
            <Modal isOpen={modalIsOpen} onRequestClose={closeModal}>
                <h2>Hello, Modal!</h2>
                <button onClick={closeModal}>Close Modal</button>
            </Modal>
        </div>
    );
};

In the above example, we use the useState hook to manage the state of the modal. Clicking the "Open Modal" button toggles the visibility of the modal. React Modal provides options for customizing the appearance, behavior, and accessibility of modals.

React Lazy Load Image

React Lazy Load Image is a library that enables lazy loading of images in your React application. Lazy loading delays the loading of images until they are about to be visible in the viewport, improving the initial page load performance. Here's a basic example of using React Lazy Load Image:

import LazyLoadImage from 'react-lazy-load-image-component';
// import library css
import 'react-lazy-load-image-component/src/effects/blur.css';
 
const MyComponent = () => {
    return (
        <div>
            <LazyLoadImage
                src="path/to/image.jpg"
                alt="Image"
                effect="blur"
                width={500}
                height={300}
            />
        </div>
    );
};

In the above example, we import the LazyLoadImage component and specify the image source, alt text, and other attributes. React Lazy Load Image provides various effects, such as blurring or fading, to improve the user experience while images are loading.

Conclusion:

These essential React libraries, React Hook Form, React Toastify, React Modal, and React Lazy Load Image bring powerful functionalities and convenience to your React development workflow. By incorporating these libraries into your projects, you can enhance your user interfaces, simplify form management, display notifications, create modal dialogs, and improve image loading performance.
