Styled-components has released a new version, 6.1.0, building upon the solid foundation of its previous stable release, 6.0.9. While both versions maintain the core functionality of styling React components with CSS-in-JS, several key differences emerge. One notable change is in the dependencies section, where version 6.1.0 upgrades postcss to ^8.4.31 from ^8.4.23 in the previous version. This indicates potential improvements or bug fixes related to PostCSS processing within the library.
Furthermore, the newer version eliminates some @babel dependencies from its direct dependencies, suggesting a possible shift in the build process or a reduction in direct Babel involvement. This could lead to slightly improved bundle sizes or build times. The devDependencies section remains largely consistent, indicating a stable testing and development environment across both versions. However, several packages are removed from devDependencies while some others like @babel/helper-module-imports appear from dependencies, while other dependencies as @babel/cli dissapeared, which shows structural change on the build process, for example it may have migrated the package to ES modules over commonjs.
For developers, the upgrade promises mostly under-the-hood improvements. The peer dependencies for react and react-dom remain consistent, ensuring compatibility with existing React projects. The library continues to be distributed under the MIT license, and support is ongoing via Open Collective funding. The file count and unpacked size in the dist object also indicates that the new package might be smaller than the last one, and even some of the older dev dependencies are still in use. Developers should always consult the official changelog for detailed information about breaking changes or new features.
