Taiga UI 5.0 is out!

Jest
On this page
Jest runs in a Node.js environment, which means that global objects like window, document, and navigator which are present in a real web browser, are unavailable. This instructions ensures that Taiga UI components can run correctly in Jest.
Taiga UI is designed to be SSR-safe, and we use abstractions provided by @ng-web-apis/common to avoid direct access to browser globals such as window or navigator.
Installation
Most browser APIs do not exist under Node.js, so you need to have them mocked to prevent runtime errors such as
ReferenceError: IntersectionObserver is not definedTo simplify this, we provide ready-to-use mocks.
Configuration
By default, we provide a preconfigured setup that you only need to connect to your project.
Manual setup
If your project already has Jest configured and uses a custom setup-jest.ts, you only need to include our mocks.
