Quill Paste Smart

This plugin extends the default clipboard module of Quill.js to prevent users from pasting HTML that does not belong into the editor. To do so it looks into the toolbar configuration and decides which tags and attributes are allowed based on the possible formats.
However, you can also decide on your own, what is allowed.

Installation

You can install this plugin either with npm or with yarn.
Run one of the following commands from your projects root in a bash prompt.

npm i quill-paste-smart
# or: yarn add quill-paste-smart

Usage

Since this plugin registers itself, it is sufficient to just import it.

import Quill from 'quill';
import 'quill-paste-smart';

Demos

Vanilla JS
- ES6
- CommonJS
Vue
- surmon-china/vue-quill-editor
React
- zenoamaro/react-quill
- gtgalone/react-quilljs

Configuration

Out of the box this plugin will remove all HTML tags and attributes that are not available in the toolbar formats.
If you don't agree with the default settings, you can decide what is allowed by yourself.
Also I thought it could be useful to keep the pasted content selected after pasting, so there is a setting for it too.

A valid configuration could look like this:

const options = {
    theme: 'snow',
    modules: {
        clipboard: {
            allowed: {
                tags: ['a', 'b', 'strong', 'u', 's', 'i', 'p', 'br', 'ul', 'ol', 'li', 'span'],
                attributes: ['href', 'rel', 'target', 'class']
            },
            keepSelection: true,
            substituteBlockElements: true,
            magicPasteLinks: true,
            hooks: {
                uponSanitizeElement(node, data, config) {
                    console.log(node);
                },
            },

            handleImagePaste(image) {
                console.log("Image file pasted", image);
            }
        },
    },
};
new Quill('#editor', options);

:raised_hand: Probably you don't need a custom configuration.
You could stick with the default settings by completely omit the clipboard object in your quill options.

Configuration Object

key	valid values	default value	type	description
allowed.tags	HTML tags	`undefined`	`Array<string>`	Here you can define any HTML tag that should be allowed to be pasted. If this setting is not specified, allowed tags are determined by possible formats in the toolbar
allowed.attributes	HTML attributes	`undefined`	`Array<string>`	Here you can define any HTML attributes that should be allowed to be pasted. If this setting is not specified, allowed attributes are determined by possible formats in the toolbar
substituteBlockElements	`true` `false`	`true`	`Boolean`	If this setting is set to `true` all forbidden block type tags will be substituted by one of the allowed tags `p`/`div`/`section`
keepSelection	`true` `false`	`false`	`Boolean`	If this setting is set to `true` the pasted content will be selected after pasting it. Otherwise the cursor will be placed right after the pasted content
magicPasteLinks	`true` `false`	`false`	`Boolean`	If this setting is set to `true` pasted URLs over selected text will be converted to an `a` tag. Example: If you select the word `foo` and paste the URL `https://foo.bar/` the result will be `<a href="https://foo.bar/">foo</a>`. Note: This only works if there is nothing pasted except a valid URL.
hooks	DOMPurify Hooks	`undefined`	`Array<function>`	Here you can define any of the DOMPurify hooks. This can be handy if you need to cusomtize the HTML sanitizer. For more information see the hook demos from DOMPurify. BE AWARE Here you can mess up things. E.g. You could create an infinite loop by adding not allowed tags to the node.
handleImagePaste	`function (File)`	`undefined`	`function (File)`	Here you can define custom behavior for handling images being pasted, you can use this to upload the image to a CDN rather than embedding
