chore(deps-dev): bump happy-dom from 18.0.1 to 20.0.2 #2568

dependabot · 2025-10-15T20:52:34Z

Bumps happy-dom from 18.0.1 to 20.0.2.

Release notes

v20.0.2

👷‍♂️ Patch fixes

Adds frozen intrinsics flag to workers in @happy-dom/server-renderer - By @capricorn86 in task #1934

v20.0.1

👷‍♂️ Patch fixes

Adds warning for environment with unfrozen intrinsics (builtins) when JavaScript evaluation is enabled- By @capricorn86 in task #1932

A security advisory has been reported showing that the recommended preventive measure of running Node.js with --disallow-code-generation-from-strings wasn't enough to protect against attackers escaping the VM context and accessing process-level functions. Big thanks to @cristianstaicu for reporting this!

The documentation for how to run Happy DOM with JavaScript evaluation enabled in a safer way has been updated. Read more about it in the Wiki

v20.0.0

I avoid making breaking changes as much as possible in Happy DOM. When I have to make a breaking change, I try to keep it as minimal as possible. This could be a breaking change that impacts many projects, and I am truly sorry if you are negatively affected by this.

💣 Breaking Changes

Due to security risks, JavaScript evaluation is now disabled by default - By @capricorn86 in task #1930

A security advisory (GHSA-37j7-fg3j-429f) has been reported that shows a security vulnerability where it's possible to escape the VM context and get access to process level functionality. Big thanks to @Mas0nShi for reporting this!

Due to this security risk, JavaScript evaluation is now disabled by default to prevent that consumers accidentally executes untrusted code without taking precautions

JavaScript evaluation can be enabled by setting enableJavaScriptEvaluation to "true". Read more about how to enable this in a safer way in the Wiki

v19.0.2

👷‍♂️ Patch fixes

Fixes issue related to CSS pseudo selector :scope that didn't work correctly for direct descendants to root - By @capricorn86 in task #1620

v19.0.1

👷‍♂️ Patch fixes

Fixes issue with sending in URLs as string in @happy-dom/server-renderer config using CLI - By @capricorn86 in task #1908

v19.0.0

💣 Breaking Changes

Removes support for CommonJS - By @capricorn86 in task #1730

Support for CommonJS is no longer needed as Node.js v18 is deprecated and v20 and above supports loading ES modules from CommonJS using require()

Updates Jest to v30 in the @happy-dom/jest-environment package - By @capricorn86 in task #1730

Makes Jest packages peer dependencies to make it easier to align versions with the project using @happy-dom/jest-environment - By @capricorn86 in task #1730

🎨 Features

Adds a new package called @happy-dom/server-renderer - By @capricorn86 in task #1730

This package provides a simple way to statically render (SSG) or server-side render (SSR) your client-side application

Read more in the Wiki under Server-Renderer

Adds support for import.meta to the ESM compiler - By @capricorn86 in task #1730

Adds support for the CSS pseudo selector :scope - By @capricorn86 in task #1620

Improves support for MediaList - By @capricorn86 in task #1730

Adds support for CSSKeywordValue, CSSStyleValue, StylePropertyMap, StylePropertyMap, StylePropertyMapReadOnly - By @capricorn86 in task #1730

Improves debug information in the ESM compiler - By @capricorn86 in task #1730

Summary by cubic

Upgrade happy-dom from 18.0.1 to 20.0.2 to harden the test DOM environment and include recent fixes. Note: JavaScript evaluation is now disabled by default, which may affect tests that rely on <script> execution.

Migration
- If tests depend on script execution, enable it in Happy DOM settings (enableJavaScriptEvaluation: true).
- When enabling it, run Node with --frozen-intrinsics to reduce VM escape risk.
- Happy DOM is now ESM-only; update any CommonJS imports if needed.
