Dayjs saw a small but impactful update moving from version 1.5.8 to 1.5.9. While the core functionality likely remained consistent, evidenced by the near-identical devDependencies sections, several subtle changes become apparent when comparing the package metadata. Both versions maintained the same dependencies for testing (jest, eslint, moment, rollup, mockdate), code transpilation (@babel/*), and linting, signifying a stable development environment. The license remains MIT, ensuring free usage and modification for developers.
The key difference lies in the dist attribute and the release date. Version 1.5.9 was released on April 21, 2018, a day later than version 1.5.8. The unpackedSize saw a minuscule bump from 28453 bytes to 28457 bytes indicating a small code adjustment, probably a bug fix, minor code refactoring or documentation update. Developers choosing between these versions should opt for 1.5.9 to benefit from the latest subtle improvements made by the Dayjs team. Dayjs remains a lightweight and fast alternative to Moment.js, making it an ideal choice for date and time manipulation in environments where bundle size is critical. Each version includes 16 files.
