Installation

# or
yarn add @bytecrate/react-editor

Usage

import React, { useState } from 'react';
import { EmailEditor } from '@bytecrate/react-editor';

const MyEmailApp = () => {
  const [htmlContent, setHtmlContent] = useState('');

  return (
    <div className="p-10">
      <EmailEditor 
        initialValue="<p>Hello there,</p>"
        onChange={(html) => setHtmlContent(html)}
        placeholder="Start crafting your email..."
        style={{ minHeight: '400px' }}
      />
      
      <div className="mt-4">
        <h3>Output:</h3>
        <pre>{htmlContent}</pre>
      </div>
    </div>
  );
};

export default MyEmailApp;

Image Upload Handling

By default, images selected from the device are converted to Base64 strings. To upload images to a server (e.g., AWS S3, Cloudinary) and use the resulting URL, provide the onImageUpload prop.

<EmailEditor 
  onImageUpload={async (file) => {
    // Example: Upload file to your server
    const formData = new FormData();
    formData.append('image', file);
    
    const response = await fetch('/api/upload', {
      method: 'POST',
      body: formData
    });
    
    const data = await response.json();
    return data.url; // Return the hosted image URL
  }} 
/>

Custom Variables

You can pass a custom list of variables (merge tags) that appear in the {} toolbar dropdown.

const myVariables = [
  { label: 'User Name', value: '{{user.name}}' },
  { label: 'Order ID', value: '{{order.id}}' },
  { label: 'Unsubscribe', value: '{{unsubscribe_url}}' }
];

<EmailEditor 
  variables={myVariables} 
  onChange={handleChange} 
/>
