babel-preset-jest

Babel preset for Jest, part of the Jest monorepo. Current version 30.3.0, released as part of Jest 30. This preset automatically configures Babel plugins needed for Jest to work with your code (e.g., transforms for ES modules, JSX, and TypeScript). Relies on @babel/core (peer dep) and babel-jest. Key differentiator: it's the official Jest preset, ensuring compatibility with Jest's internal module transformation. Actively maintained with frequent releases alongside Jest. Not to be used standalone; instead used via babel-jest or jest config.
