Tslib is a runtime library containing helper functions for TypeScript, essential for projects compiled with the TypeScript compiler. Version 2.0.0 represents a notable update from the prior stable version, 1.14.1. Although both versions share the same core purpose and "0BSD" license, several differences might influence developer choices. Version 2.0.0 was released in May 2020, earlier than version 1.14.1, which shipped in October 2020, suggesting a potentially longer period of maturity and wider adoption for the older version by the time 2.0 came out.
While both serve the same function, the newer version, 2.0.0, boasts a smaller unpacked size (32748 bytes) and fewer files (9) compared to 1.14.1 (33965 bytes and 13 files). This reduction in size and file count could translate to slightly faster install times and a smaller footprint in project dependencies, a consideration for performance-sensitive applications. However, the decrease in file count could also indicate changes in the structure or organization of the library's code. Developers should familiarize themselves with the changelog to understand the exact nature of the changes and potential impact on their projects. Depending on project specifics, they might stay with a tried and tested version 1.14.1 or move to a leaner and more recent version 2.0.0. Always check for potential breaking change when upgrading a dependency.
