Dayjs is a lightweight JavaScript date library, offering a modern alternative to Moment.js with a focus on immutability and a tiny 2KB footprint. Versions 1.8.12 and 1.8.13 showcase its ongoing development and commitment to improvement. While both versions share the same core API and philosophy, a closer look reveals subtle yet important modifications.
The key difference lies in the dist folder, specifically the file count (333 vs 336) and especially the unpacked size (312832 bytes vs 386277 bytes) that jumped by 73KB, this can indicate that the newer version has more features or some refactor related to locales. Developers should evaluate if upgrading from 1.8.12 to 1.8.13 is worth the extra space. Both versions offer a comprehensive set of features for parsing, validating, manipulating, and formatting dates and times, this is clear because the dependencies and devDependencies sections are identical. The release dates, roughly three weeks apart, suggest a regular cadence of updates and bug fixes. Dayjs is designed to be easy to use with a familiar API for those transitioning from Moment.js. Its small size makes it an excellent choice for front-end projects where minimizing bundle size is crucial for improving page load times. The MIT license ensures the library can be freely used in both personal and commercial projects.
