jest-environment-node-single-context offers a Jest environment that creates a single Node.js context for all tests within a suite. This can significantly improve test performance, especially for computationally intensive tests, by avoiding the overhead of creating a new context for each test file. It's an alternative to the default Jest Node environment, designed for speed optimization in specific scenarios. However, be mindful of potential state pollution issues between tests when using this environment.
The jest-environment-node-single-context npm package had sporadic releases between July 2020 and December 2024. There were periods of consistent monthly releases (e.g., early 2022), but longer stretches with no releases, especially from late 2022 through 2023 and all of 2024 except for January where two versions were released. No releases have occurred in 2025.
Jest-environment-node-single-context downloads show an upward trend from March 2024 to June 2025, peaking at 168,827. Subsequently, there's a decline in July and August 2025. September 2025, being incomplete, shows significantly lower downloads compared to previous months, but the average number of downloads per month in 2025 is higher than in 2024.
