quill2-delta-html

Convert Quill 2 Delta to HTML or plain text.

Zero dependencies. Cloudflare Workers / Edge Runtime safe.

Why?

The existing quill-delta-to-html package:

• Is abandoned (last published April 2022)
• Depends on lodash.isequal, which uses Function('return this')() — prohibited in Cloudflare Workers and Edge Runtimes
• Has no Quill 2 support

This package is a minimal, zero-dependency replacement that handles all standard Quill 2 formats.

Install

npm install quill2-delta-html

Usage

import { deltaToHtml, deltaToPlainText } from 'quill2-delta-html'

const delta = JSON.stringify({
  ops: [
    { insert: 'Hello ' },
    { insert: 'world', attributes: { bold: true } },
    { insert: '\n' }
  ]
})

deltaToHtml(delta)
// => '<p>Hello <strong>world</strong></p>'

deltaToPlainText(delta)
// => 'Hello world'

Supported formats

All standard Quill 2 formats:

| Category | Formats | |----------|---------| | Inline | bold, italic, underline, strike | | Style | color, background | | Link | link (with target="_blank") | | Block | header (1-6), blockquote, code-block | | List | ordered, bullet | | Layout | align, indent | | Embed | image, video |

Backward compatibility

If the input is not valid Quill Delta JSON (e.g. legacy HTML or plain text), both functions handle it gracefully:

• deltaToHtml() returns the input unchanged
• deltaToPlainText() strips HTML tags and returns the text

This makes migration safe — existing HTML content passes through without breaking.

API
