Usage

Webpack/ES6

import Quill from 'quill';
import QuillResize from 'quill-resize-module';
Quill.register('modules/resize', QuillResize);

const quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        resize: {
            // See optional "config" below
        }
    }
});

Script Tag

Copy resize.js into your web root or include from node_modules

<script src="/node_modules/quill-resize-module/dist/resize.js"></script>

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        resize: {
            // See optional "config" below
        }
    }
});

Config

For the default experience, pass an empty object, like so:

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        resize: {}
    }
});

Functionality is broken down into modules, which can be mixed and matched as you like. For example, the default is to include all modules:

const quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        resize: {
            modules: [ 'Resize', 'DisplaySize', 'Toolbar' ]
        }
    }
});

Customize the toolbar buttons with "tools" option.

For example, add handler for image alt attribute:

const quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        resize: {
            tools: [
              'left', 'right',
              {
                text: 'Alt',
                verify (activeEle) {
                    return (activeEle && activeEle.tagName === 'IMG')
                },
                handler (evt, button, activeEle) {
                    let alt = activeEle.alt || ''
                    alt = window.prompt('Alt for image', alt)
                    if (alt == null) return
                    activeEle.setAttribute('alt', alt)
                }
              }
            ]
        }
    }
});

Resize - Resize the element

Adds handles to the element's corners which can be dragged with the mouse to resize the element.

The look and feel can be controlled with options:

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        resize: {
            // ...
            // set parchment key to enable resize module
            parchment: {
                image: {
                    attribute: ['width'],  // ['width', 'height']
                    limit: {
                        minWidth: 200,
                        maxWidth: 600,
                        minHeight: 200,
                        maxHeight: 450,
                        ratio: .5625  // keep width/height ratio. (ratio=height/width)
                    }
                }
            }
        }
    }
});

BaseModule - Include your own custom module

You can write your own module by extending the BaseModule class, and then including it in the module setup.

For example,

import QuillResize from 'quill-resize-module';
Quill.register('modules/resize', QuillResize);

class MyModule extends QuillResize.Modules.Base {
    // See src/modules/BaseModule.js for documentation on the various lifecycle callbacks
}

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        resize: {
            modules: [ MyModule, QuillResize.Modules.Resize ],
            // ...
        }
    }
});
