Mastering React Quill: A Step-by-Step Guide to Implement a Rich Text Editor in Your React App

In the modern digital landscape, rich text editors have become a cornerstone for building user-friendly interfaces. From blog platforms to content management systems (CMS), they empower users to craft beautifully formatted content with ease. One of the most robust and widely-used tools for this purpose in React is React Quill.

This guide will take you on a journey to integrate and customize React Quill in your React application, making your interface dynamic and feature-rich.

Why React Quill?
React Quill is a wrapper for the powerful Quill.js editor. It offers a lightweight and modular solution for rich text editing in React applications, featuring:

Rich Text Formatting: Support for bold, italic, underline, and more.
Customizable Toolbar: Tailor the editor to include only the features you need.
Lightweight and Flexible: Highly customizable with minimal setup.
React-Friendly Architecture: Seamless integration into React’s component model.
Whether you’re building a blog editor, a messaging app, or a CMS, React Quill is your go-to solution.

Step 1: Installing React Quill
To get started, install React Quill and its peer dependency, Quill, using npm or yarn.

npm install react-quill quill

Step 2: Importing React Quill and Its Styles
React Quill relies on Quill’s styles for its appearance. Import the editor and its default theme (snow) into your component.

Import quill and css for that

import React, { useState } from 'react';
import ReactQuill from 'react-quill';
import 'react-quill/dist/quill.snow.css'

Step 3: Creating a Basic Editor Component
Here’s how to set up a simple rich text editor:

const RichTextEditor = () => {
  const [content, setContent] = useState('');

  const handleContentChange = (value) => {
    setContent(value);
  };

  return (
    <div>
      <h2>Rich Text Editor</h2>
      <ReactQuill
        theme="snow"
        value={content}
        onChange={handleContentChange}
      />
      <h3>Preview:</h3>
      <div dangerouslySetInnerHTML={{ __html: content }} />
    </div>
  );
};

export default RichTextEditor;

Step 4: Customizing the Toolbar
Out of the box, React Quill provides a comprehensive toolbar. However, you can customize it to include only the features you need, enhancing usability and focusing on specific functionalities.

Custom Toolbar Configuration:

const modules = {
  toolbar: [
    [{ header: [1, 2, false] }], 
    ['bold', 'italic', 'underline'], 
    [{ list: 'ordered' }, { list: 'bullet' }], 
    ['link', 'image'], 
  ],
};

const formats = [
  'header',
  'bold',
  'italic',
  'underline',
  'list',
  'bullet',
  'link',
  'image',
];
Applying the Custom Toolbar:
javascript
Copy code
<ReactQuill
  theme="snow"
  value={content}
  onChange={handleContentChange}
  modules={modules}
  formats={formats}
/>

Step 5: Adding the Editor to a Form
If you want to use the editor as part of a form, ensure the content is submitted correctly:

const handleSubmit = (e) => {
  e.preventDefault();
  console.log('Submitted Content:', content);
};

return (
  <form onSubmit={handleSubmit}>
    <ReactQuill
      theme="snow"
      value={content}
      onChange={handleContentChange}
      modules={modules}
      formats={formats}
    />
    <button type="submit">Submit</button>
  </form>
);

Step 6: Adding Validation
To ensure quality input, validate the editor’s content before submission. For example, you can prevent submission if the content is empty:

const handleSubmit = (e) => {
  e.preventDefault();
  if (!content || content.trim() === '<p><br></p>') {
    alert('Content cannot be empty!');
    return;
  }
  console.log('Valid Content:', content);
};

Step 7: Advanced Customization
1. Custom Styling
Customize the editor’s appearance by overriding the default styles.

.ql-container {
  font-family: 'Grotesk', sans-serif;
  min-height: 300px;
}

.ql-toolbar {
  background-color: #f8f9fa;
  border: 1px solid #ced4da;
}

2. Image Upload Handling
React Quill supports images, but to upload images to a server, you’ll need to extend its functionality. You can add a custom handler for the image button in the toolbar.

Step 8: Server-Side Rendering (SSR)
React Quill depends on the window object, which can cause issues with SSR frameworks like Next.js. To address this, dynamically import React Quill on the client side:

import dynamic from 'next/dynamic';

const ReactQuill = dynamic(() => import('react-quill'), { ssr: false });

Use Cases of React Quill

• Blog Platforms: Enable users to create and format posts easily.

• Messaging Apps: Allow rich text formatting in messages.

• Content Management Systems: Help content creators manage dynamic content.

• Email Builders: Provide drag-and-drop interfaces for creating styled emails.
