@jest/transform is a core Jest module responsible for transforming source code before test execution. It uses configurable transformers to handle various file types, like JavaScript, TypeScript, or CSS, converting them into a format Jest can understand. This allows you to write tests using modern syntax and frameworks. It is highly configurable, enabling diverse project setups.
@jest/transform's release frequency is highly variable. It was active in 2019-2023, with peaks in early 2020 and late 2021. There were no releases between October 2023 and May 2025. The package saw a minor resurgence in June and July 2025, but the overall trend shows declining and inconsistent activity.
@jest/transform npm package downloads show a generally increasing trend from February 2024 to July 2025. Downloads ranged from ~49 million to ~193 million per month. August 2025 downloads are significantly lower at ~89 million, but the month isn't complete, so it shows a potential decline.
