Version Details and Security Vulnerabilities

@swc/core is a super-fast alternative to Babel, designed to accelerate your JavaScript and TypeScript compilation process. Version 1.2.5 builds upon the solid foundation of version 1.2.4, offering incremental improvements that enhance the developer experience. Both versions share the same core dependencies like mkdirp, progress, node-fetch, and true-case-path, indicating a stable base for essential functionalities. Similarly, the devDependencies remain consistent, ensuring a familiar development environment with tools like jest for testing, lodash for utility functions, typescript for type checking, and various Babel plugins and presets for broader compatibility.

While the declared dependencies are identical, the key difference lies in the dist section. Version 1.2.5 exhibits a slight increase in fileCount (460 vs 459) and unpackedSize (3544003 vs 3543447 bytes). This suggests that version 1.2.5 likely contains minor bug fixes, performance tweaks, or code adjustments, possibly addressing edge cases or optimizations discovered since the release of version 1.2.4. Although not explicitly stated, these subtle changes underscore the project's commitment to continuous improvement and refinement. The release date difference (June 18, 2020 vs June 17, 2020) confirms this is a patch or minor release. For developers already using @swc/core, upgrading to 1.2.5 is recommended to benefit from the latest enhancements.
