Creating user-friendly and efficient tools is essential. WYSIWYG (What You See Is What You Get) editors help users create and format content without needing to know HTML or CSS. Lightweight WYSIWYG editors are especially popular because they load quickly and are easy to integrate into projects. However, to make these editors even more powerful, adding a file uploader is a great idea. This guide will show you how to add a file uploader to a lightweight WYSIWYG editor using Froala and Filestack as examples.

What is a Lightweight WYSIWYG Editor?

A WYSIWYG editor allows users to see how their content will look while they are creating it. A lightweight editor means it has a small file size, loads quickly, and doesn’t use a lot of computer resources. These editors are perfect for projects where speed and efficiency are important.

Why Choose Lightweight Editors?

Faster Performance: They load quickly, making your website or application run smoother.
Easy to Integrate: Simple to add to your project without complicated setup.
Customizable: Easy to adjust to fit your specific needs.
Better User Experience: Provides a smooth and responsive interface for creating content.

Why Add a File Uploader?

Adding a file uploader to your WYSIWYG editor makes it easier for users to include images, videos, documents, and other media in their content. This not only makes the content more engaging but also improves the overall user experience.

Benefits of File Uploaders:

Richer Content: Users can add various types of media to their content.
User-Friendly: Features like drag-and-drop and multiple file uploads make it easy to use.
Developer Efficiency: Offloads the task of handling files to specialized services, saving time and effort.

Step-by-Step Tutorial: Integrating Filestack with Froala

Follow these simple steps to add a file uploader to your Froala editor using Filestack.

1. Set Up Your Development Environment

First, you need to include the necessary CSS and JavaScript files for both Froala and Filestack in your HTML file.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Froala & Filestack Integration</title>
  <!-- Load Froala Editor CSS files -->
  <link href='https://cdn.jsdelivr.net/npm/[email protected]/css/froala_editor.pkgd.min.css' rel='stylesheet' type='text/css' />
  
  <!-- Load Filestack Transformation UI CSS files -->
  <link rel="stylesheet" href="https://static.filestackapi.com/transforms-ui/2.x.x/transforms.css" />
</head>
<body>
  <div id="editor">Type something...</div>

  <!-- Load Filestack JS -->
  <script src="https://static.filestackapi.com/filestack-js/3.32.0/filestack.min.js"></script>       
  <script src="https://static.filestackapi.com/filestack-drag-and-drop-js/1.1.1/filestack-drag-and-drop.min.js"></script>
  
  <!-- Load Filestack Transformation UI JS -->
  <script src="https://static.filestackapi.com/transforms-ui/2.x.x/transforms.umd.min.js"></script>
  
  <!-- Load Froala Editor JS files -->
  <script type='text/javascript' src='https://cdn.jsdelivr.net/npm/[email protected]/js/froala_editor.pkgd.min.js'></script>
  
  <!-- Initialize Froala Editor with Filestack Integration -->
  <script>
    const filestackClient = filestack.init('YOUR_FILESTACK_API_KEY'); // Replace with your Filestack API key

    // Initialize the Froala Editor
    new FroalaEditor('#editor', {
      imageEditButtons: ['imageReplace', 'imageAlign', 'imageCaption', 'filestackIcon', 'imageTUI'],

      filestackOptions: {
        uploadToFilestackOnly: false,
        filestackAPI: 'YOUR_FILESTACK_API_KEY', // Replace with your Filestack API key
        pickerOptions: {
          fromSources: [
            'local_file_system',
            'imagesearch',
            'url',
            'googledrive',
            'facebook',
          ],
          accept: [
            ".pdf",
            "image/jpeg",
            "image/png",
            "image/webp",
            "video/*",
            "audio/*"
          ],
          transformations: {
            "crop": true,
            "rotate": true
          }
        },
      },
    });
  </script>
</body>
</html>

2. Initialize the Froala Editor

The HTML above sets up the Froala editor inside a div with the ID editor. The Froala Editor is initialized with options that allow it to work with Filestack for file uploads.

3. Configure Filestack Integration

In the JavaScript section, you need to initialize Filestack with your API key and configure Froala to use Filestack for handling file uploads.

const filestackClient = filestack.init('YOUR_FILESTACK_API_KEY'); // Replace with your Filestack API key

// Initialize the Froala Editor
new FroalaEditor('#editor', {
  imageEditButtons: ['imageReplace', 'imageAlign', 'imageCaption', 'filestackIcon', 'imageTUI'],

  filestackOptions: {
    uploadToFilestackOnly: false,
    filestackAPI: 'YOUR_FILESTACK_API_KEY', // Replace with your Filestack API key
    pickerOptions: {
      fromSources: [
        'local_file_system',
        'imagesearch',
        'url',
        'googledrive',
        'facebook',
      ],
      accept: [
        ".pdf",
        "image/jpeg",
        "image/png",
        "image/webp",
        "video/*",
        "audio/*"
      ],
      transformations: {
        "crop": true,
        "rotate": true
      }
    },
  },
});

Key Options Explained:

imageEditButtons: Adds Filestack-specific buttons to the image editing toolbar in Froala.
filestackOptions:
- uploadToFilestackOnly: If set to true, only Filestack handles uploads. If false, other sources can also upload files.
- filestackAPI: Your Filestack API key for authenticating upload requests.
- pickerOptions:
  - fromSources: Lists the sources users can upload files from, like their local system or Google Drive.
  - accept: Specifies the types of files users can upload, such as PDFs and images.
  - transformations: Enables options like cropping and rotating images directly in the uploader.

4. Exploring Advanced Integration Modes

Froala offers different ways to integrate with Filestack, allowing you to choose how much control you want over the upload process.

Demo #1: Basic Mode

In Basic Mode, Filestack’s file picker and transformation tools are added to Froala’s existing upload options. This mode enhances Froala without changing its default upload behavior.

new FroalaEditor('#editor', {
  imageEditButtons: ['imageReplace', 'imageAlign', 'imageCaption', 'filestackIcon', 'imageTUI'],

  filestackOptions: {
    uploadToFilestackOnly: false,
    filestackAPI: 'YOUR_FILESTACK_API_KEY',
    pickerOptions: {
      fromSources: [
        'local_file_system',
        'imagesearch',
        'url',
        'googledrive',
        'facebook',
      ],
      accept: [
        ".pdf",
        "image/jpeg",
        "image/png",
        "image/webp",
        "video/*",
        "audio/*"
      ],
      transformations: {
        "crop": true,
        "rotate": true
      }
    },
  },
});

Demo #2: Advanced (Filestack-only) Mode

Advanced Mode uses Filestack exclusively for all file uploads in Froala. This gives you complete control over the upload process through Filestack.

new FroalaEditor('#editor', {

  filestackOptions: {
    uploadToFilestackOnly: true,
    filestackAPI: "YOUR_FILESTACK_API_KEY"
  },

  events: {
    'filestack.uploadedToFilestack': function (response) {
      console.log("File uploaded to Filestack:", response);
    },

    'filestack.filestackPickerOpened': function () {
      console.log("Filestack picker opened");
    },

    'filestack.filestackPickerClosed': function () {
      console.log("Filestack picker closed");
    },

    'filestack.uploadFailedToFilestack': function (error) {
      console.log("File upload failed:", error);
    },
  },

});

Key Points in Advanced Mode:

uploadToFilestackOnly: Set to true to ensure all uploads go through Filestack.
events: Customize how your application responds to different stages of the upload process, like when a file is uploaded or if an upload fails.

Demo #3: Enable Transformation UI after Image Uploads

Filestack’s Transformation UI allows users to edit images right after uploading. They can adjust brightness, contrast, size, and apply filters. To enable this feature, adjust the transformationsUI option.

Benefits of Transformation UI:

Real-Time Editing: Users can edit images immediately after uploading.
Professional Enhancements: Apply filters and effects easily.
User-Friendly Interface: Simple controls make it easy for users to customize images.
