Rollup Plugin Visualizer is a valuable tool for developers using Rollup, providing insights into bundle contents and dependencies. Examining versions 4.0.2 and 4.0.1 reveals subtle, yet potentially impactful differences. Both versions share identical dependencies, including "open," "pupa," "yargs," "nanoid," and "source-map," as well as development dependencies like "htm," "sass," "eslint," "preact," and various D3 libraries. They also maintain the same peer dependency on Rollup (>=1.20.0) ensuring compatibility with a range of Rollup versions. Crucially, both are licensed under MIT, offering flexibility in usage.
The key differences lie in the release date and unpacked size. Version 4.0.2 was released on March 31, 2020, while version 4.0.1 was released on March 29, 2020, indicating a quick follow-up release. A minor difference also exists in "unpackedSize", 1444037 vs 1443959. The fact that those 2 variables and their differences are the only change between the 2 versions, indicates that some tiny adjustment of code or documentation changes must've been done.
The very minimal differences are the kind that developers should not worry about, since they mostly affect internal aspects of the library and some typo fixes, thus, for the developers, upgrading to the latest minor version becomes a no-brainer. The visualizer helps fine-tune Rollup configurations, identify large dependencies, and optimize bundle size, ultimately improving application performance and user experience.
