@happy-dom/jest-environment 9.0.0

v9.0.0

on Node.js Yarn

💣 Breaking Changes

• This release doesn't contain any expected breaking changes, but as it contains many major internal changes and there is a risk that it introduces bugs, it felt safer to release it with a major version number.

🎨 Features

• Implements Window.fetch(), Window.Request, Window.Response and Window.Headers in Happy DOM, instead of using the "node-fetch" library. The code is based on "node-fetch". This improves the integration for functionality such as FormData, Blob, AbortController and AbortSignal with Window.fetch(). It will also make it possible to add support for ESM while still keeping support for CommonJS.

• Adds support for AbortController and AbortSignal. (#470)
