Brace expansion is a handy npm package providing brace expansion functionality, mirroring the behavior found in shells like sh/bash. Comparing version 2.0.0 with the older 1.1.12, several key differences emerge that are pertinent for developers. Version 2.0.0 boasts a streamlined dependency list, relying solely on "balanced-match" as a dependency. This is a departure from version 1.1.12, which included both "balanced-match" and "concat-map". This reduction in dependencies can lead to a slightly smaller installation footprint and potentially faster installation times, desirable qualities for modern javascript projects. Also affecting the install image is the fact that the new package appears to have one more file but a comparable unpackedSize.
Both versions share the same core functionality, offering brace expansion as defined in shell scripting. They also maintain consistency in developer tooling, with "tape" and "matcha" used for testing across both versions. Furthermore, they are both licensed under the MIT license, offering developers flexibility in how they integrate the package into their projects, both personal and commercial. Julian Gruber remains the author of both versions, ensuring continuity in maintainership.
One notable oddity is the releaseDate, showing the old version being released in the future. Developers should verify if this is intended behavior, or a mistake in the registry data.
For developers considering this library, the choice between versions might hinge on dependency management preferences. If minimizing dependencies is a priority, version 2.0.0's leaner profile might be preferred. Otherwise the 2 packages are very similar and can be used interchangeably.
