Version Details and Security Vulnerabilities

Jest-fetch-mock version 3.0.3 represents a minor update to the popular Jest testing utility, building upon the foundation laid by version 3.0.2. Both versions maintain the same core dependencies, including cross-fetch for providing a Fetch API environment in Node.js and promise-polyfill for broader browser compatibility. Development dependencies for testing and linting, such as @types/jest, dtslint, jest, prettier, and typescript, also remain consistent, suggesting a focus on internal improvements rather than significant API changes. Key differences lie in the package metadata. Version 3.0.3 has an increased file count (29 vs 21) and a slightly larger unpacked size (103657 vs 102700), indicating the addition of files or modifications to existing ones. Crucially, version 3.0.3 was released on March 10, 2020, six days after version 3.0.2 which was released on March 4, 2020. The increment in fileCount and unpackedSize, along with the difference in the release date should be evaluated in more detail. Developers already using jest-fetch-mock should investigate what files have been added by comparing the two package files, while new adopters can expect a refined, potentially more robust, and well-tested fetch mocking solution suitable for their Jest-based testing workflows.
