In today’s blog post, we will explore how to implement rich text editing in a web application using Redux and the Draft.js library. Rich text editing allows users to format text, apply styling, and insert media such as images or videos.

Why use Redux and Draft.js?

Redux is a predictable state container for JavaScript applications, commonly used with React. It helps manage application state and makes it easier to build complex UIs. Draft.js is a powerful and flexible JavaScript library for building rich text editors. It provides a set of customizable components and an API to handle text formatting and styling.

Getting started

To get started, let’s assume you have a basic Redux setup in your application. If not, refer to the Redux documentation for guidance on setting up Redux in your project.

1. Install the Draft.js library by running npm install draft-js.

2. Create a new file, RichTextEditor.js, and import the necessary components and functions:

import React, { useState } from 'react';
import { Editor, EditorState, RichUtils } from 'draft-js';
// other necessary imports

1. Define the RichTextEditor component and its initial state:

const RichTextEditor = () => {
  const [editorState, setEditorState] = useState(EditorState.createEmpty());

  const handleEditorChange = (newEditorState) => {
    setEditorState(newEditorState);
  };

  return (
    <div>
      <Editor editorState={editorState} onChange={handleEditorChange} />
      {/* other UI components and actions */}
    </div>
  );
};

1. Next, we need to add UI components and actions to enable text formatting and styling. For example, you can add buttons for bold, italic, and underline:

const formatText = (e, style) => {
  e.preventDefault();
  setEditorState(RichUtils.toggleInlineStyle(editorState, style));
};

return (
  <div>
    <button onClick={(e) => formatText(e, 'BOLD')}><strong>B</strong></button>
    <button onClick={(e) => formatText(e, 'ITALIC')}><em>I</em></button>
    <button onClick={(e) => formatText(e, 'UNDERLINE')}><u>U</u></button>
    {/* other UI components and actions */}
  </div>
);

1. Save the file and import the RichTextEditor component in your desired location within your application.

2. Now you can use the RichTextEditor component in your application. Whenever a user selects text and clicks one of the formatting buttons, the text will be formatted accordingly.

Conclusion

In this blog post, we have learned how to implement rich text editing using Redux and the Draft.js library. Redux helps manage the state of the rich text editor, while Draft.js provides the necessary components and functions for text formatting and styling. By following the steps outlined above, you can easily incorporate rich text editing into your web application.
