@swc/core versions 1.2.12 and 1.2.11 are both rapid JavaScript and TypeScript compilers designed as a high-performance alternative to Babel. Both versions share the same core dependencies including mkdirp, progress, node-fetch, and true-case-path, along with identical development dependencies such as jest, lodash, neon-cli, source-map, typescript, and a suite of Babel-related tools and plugins that are used for testing and development. This consistent dependency structure indicates a stable development environment and a focus on maintaining compatibility across builds.
The minor version bump from 1.2.11 to 1.2.12 may indicate bug fixes, performance improvements, or minor feature additions. While the core functionality remains consistent, developers should note the increment from version 1.2.11, released on August 2, 2020, to version 1.2.12, released on August 6, 2020, which suggests that the newer one includes recent refinements. The dist object shows that the unpackedSize has slightly increased from 3574494 bytes in 1.2.11 to 3579197 in 1.2.12 which reflects enhancements and new functionalities or bug fixes that have been added to the package. Developers should migrate to the newest version to get the latest features and fixes. The package is under the MIT license and contributions are welcomed.
