is-builtin-module is a small, efficient npm package designed to determine if a given string corresponds to the name of a built-in Node.js module. Comparing versions 5.0.0 and 4.0.0 highlights several key updates relevant for developers.
The most significant change lies in the updated dependency on the builtin-modules package. Version 5.0.0 utilizes builtin-modules version ^5.0.0, while version 4.0.0 relies on ^4.0.0. This indicates that version 5.0.0 likely includes support for newer Node.js versions and their corresponding built-in modules, ensuring compatibility with the latest JavaScript runtime environments. Developers upgrading should verify that their code remains compatible with any potential changes in how built-in modules are handled or identified.
Furthermore, the development environment has seen updates. Version 5.0.0 uses newer versions of development dependencies such as AVA for testing (^6.2.0 vs ^6.1.2) and XO for linting (^0.60.0 vs ^0.58.0), suggesting improved code quality and testing rigor. tsd version ^0.31.2 was also added to version 5.0.0, probably to improve TypeScript definitions. The file count remains consistent at 5, but the unpacked size slightly decreased from 3944 bytes in version 4.0.0 to 3864 bytes in version 5.0.0, pointing to potentially minor optimizations. Finally, version 5 will be released on the 27th of February 2025, meaning that it's not released yet and developers should wait until that date to use it.
