Version Details and Security Vulnerabilities

@swc/core, the blazing-fast alternative to Babel, has a new release! Version 1.5.20 arrives hot on the heels of 1.5.19, both maintaining their core promise of rapid JavaScript and TypeScript compilation. Developers relying on SWC for performance-critical transformations will be pleased to see continued activity and improvements. While the core dependencies and dev dependencies such as Jest, cross-env & typescript remain consistent between the releases, a couple of interesting changes are notable.

The fileCount within the distributed package has increased slightly from 21 to 22. More significantly, the unpackedSize demonstrates a tangible increase, jumping from 11917 bytes in version 1.5.19 to 20503 bytes in version 1.5.20. This suggests that the latest version includes significant new functionality or expanded data, potentially impacting install sizes and initial load times, so it would be wise for developers to benchmark build tasks when integrating it. Crucially, the releaseDate, also showing that the new version arrived only 40 minutes later, implies a speedy iteration, likely containing quick fixes or minor improvements after the original. For developers, this update warrants investigation into what caused the considerable unpacked size increase within the library and understand if it impacts current workflows.
