username-sync

The `username-sync` package provides a synchronous method to retrieve the system username, specifically designed for Node.js environments running version 0.12 and earlier. Published as version 1.0.3, this utility serves as a transitional bridge for applications still operating on these legacy Node.js runtimes. Its primary differentiator is its synchronous API, which was more common and sometimes necessary in older Node.js contexts before the widespread adoption of `async`/`await` and Promises for I/O operations. The package explicitly advises users on Node.js versions 4.x and newer to migrate to the `username` package by Sindre Sorhus, which offers similar functionality with modern API conventions and broader compatibility. There is no active release cadence for `username-sync` as its purpose is to support a specific, outdated environment, and it is considered superseded by `username` for current development.
