Dayjs, a lightweight JavaScript date library alternative to Moment.js, released version 1.5.5 shortly after version 1.5.4. Both versions maintain the core philosophy of being small, fast, and easy to use for parsing, validating, manipulating, and formatting dates. A key difference for developers investigating these versions lies in the unpacked size; version 1.5.5 weighs in at approximately 26KB, noticeably larger than version 1.5.4, which is around 19KB. This increase in size may be attributed to bug fixes, performance improvements, or new features introduced in the newer version.
Both versions boast identical development dependencies, showcasing a consistent testing and building environment utilizing tools such as Jest for testing, ESLint for code linting, Rollup for bundling, and Babel for transpilation. This indicates a focus on code quality and maintainability across both point releases. The consistent development dependencies also suggest that upgrading from 1.5.4 to 1.5.5 shouldn't introduce any breaking changes related to the development workflow for projects already using Dayjs. Developers should consider the potential impact of the increased size when choosing between the versions, balancing it against any potential bug fixes or performance enhancements in 1.5.5. Both versions are licensed under MIT, promoting free and open usage.
