@swc/core is a super-fast JavaScript/TypeScript compiler, designed as a performant alternative to Babel. Version 1.2.160 introduces incremental improvements over the previous stable version, 1.2.159. The core functionality remains the same: transforming modern JavaScript and TypeScript code for broader browser compatibility and optimized execution.
The primary differences between the two versions lie in the dependency updates. While both share similar development dependencies (like Jest, React, and various Babel plugins), the core dependencies and optional dependencies are version-locked to their respective package version. This suggests internal updates and bug fixes within the SWC ecosystem itself.
For developers using @swc/core, the upgrade from 1.2.159 to 1.2.160 should be relatively seamless. The focus remains on speed and efficiency, leveraging Rust-based compilation. SWC's strong performance, especially in large codebases, can significantly improve build times. Developers can expect continued benefits from using a modern compiler that supports the latest language features and provides optimized output, especially when they also use the specific platform binaries. Upgrading ensures access to the freshest bug fixes and internal improvements within the SWC compiler.
