3.0.0: ESM Support + Memory Leak Fix for Long-Running Server Processes

isomorphic-dompurify v3.0.0

ESM Support

The library now ships proper ESM alongside CommonJS. Both import and require work out of the box with correct module resolution.

// ESM — now works natively
import DOMPurify, { sanitize } from "isomorphic-dompurify";
// CJS — still works
const DOMPurify = require("isomorphic-dompurify");

Memory Leak Fix for Long-Running Server Processes

New clearWindow() export that closes the internal jsdom window and creates a fresh one, preventing unbounded memory growth and progressive slowdown in long-running Node.js processes (#368).

import { sanitize, clearWindow } from "isomorphic-dompurify";
// Call clearWindow() when you want to release accumulated DOM state,
// e.g. periodically, after a batch, or per-request in a server:
app.use((req, res, next) => {
res.on("finish", () => clearWindow());
next();
});

Note: clearWindow() is a no-op in the browser build (no jsdom to manage). Any hooks or config set via addHook/setConfig will need to be re-applied after calling it.

Breaking Changes

• Named exports are now available. sanitize, addHook, removeHook, removeHooks, removeAllHooks, setConfig, clearConfig, isValidAttribute, isSupported, version, and removed are all exported directly.
• global.DOMPurify singleton removed. The library no longer writes to global.DOMPurify. Module caching provides singleton behavior in both ESM and CJS. This also fixes a security concern where malicious code could preempt the global before the module loaded (#324).
• Build output moved to dist/. Entry points are now dist/index.js (CJS), dist/index.mjs (ESM), dist/browser.js (CJS), dist/browser.mjs (ESM). The exports map handles this automatically — no changes needed for consumers using standard imports.
• Type definitions are auto-generated. The hand-written index.d.ts using export = DOMPurify is replaced by generated .d.ts and .d.mts files with proper export default and named exports.
• Node.js version constraint tightened. Now requires ^20.19.0 || ^22.12.0 || >=24.0.0 to match jsdom 28's requirements. Node 21.x, 23.x, and 22.0–22.11 are no longer supported.

Issues Fixed

• #368 — Memory leak and progressive slowdown in long-running Node.js processes
• #163 — ESM support
• #324 — Security concern with global.DOMPurify
• #353 — lru-cache ESM resolution errors in Nuxt/Nitro builds
• #350 — Build error with Astro + Cloudflare adapter
• #203 — Build error in Angular Universal
