Jest Environment JSDOM version 29.1.1 is a minor release update to the popular Jest testing environment that emulates a browser environment using JSDOM. Comparing it to the previous stable version, 29.1.0, reveals key updates primarily focused on dependency bumps within the Jest ecosystem. Specifically, jest-mock, @jest/util, @jest/types, @jest/environment, and @jest/fake-timers have all been updated from version 29.1.0 to 29.1.1. These internal dependency updates likely include bug fixes, performance improvements, or adjustments to align with other Jest core packages.
For developers, the impact of upgrading from 29.1.0 to 29.1.1 should be minimal, assuming no direct dependencies on the specific internal packages mentioned. The core functionality of the jest-environment-jsdom remains the same – providing a realistic browser context for running JavaScript tests in a Node.js environment. Upgrading is generally recommended to benefit from accumulated bug fixes and potential performance enhancements within the Jest ecosystem. The '@types/node' dependency remains a wildcard '*', indicating it will use the latest available type definitions for Node.js, potentially offering better compatibility with newer Node.js versions. Developers should always review release notes for the updated internal dependencies to understand the specific changes included in those packages. Note the release date difference is within an hour, suggesting the 29.1.1 release was to fix a bug as a very small patch or typo.
