Restore project-specific npm metadata URLs.
repository.url, bugs.url, and homepage now point to the GitHub root. npm users cannot reach this project's repository or issue tracker from the package metadata. Restore the full project-specific URLs before publishing.

Vite 8 build.lib.cssFileName function-valued fileName default CSS filename
💡 Result:
In Vite 8, the build.lib.cssFileName option allows you to explicitly specify the name of the CSS file generated during library mode builds [1][2][3]. Regarding its default behavior and usage: - Default Value: If cssFileName is not provided, it defaults to the value used for the JavaScript bundle's file name (if configured as a string) [1][2][3]. If the JavaScript file name is not set as a string, it falls back to the "name" property defined in your package.json [1][2][3]. - Type: build.lib.cssFileName accepts a string [1][2][3]. Unlike build.lib.fileName, which supports both string and function-valued inputs (the latter providing format and entryName arguments), cssFileName is currently documented strictly as a string option [1][2][3]. - Behavior when fileName is a function: If you use a function for build.lib.fileName to dynamically name your JS files, cssFileName does not automatically inherit that function-based logic [1][2][3]. Because cssFileName expects a static string, you must provide a fixed string value if you wish to override the default (the package.json "name") [1][2][3]. For context, this structure was refined in Vite 6, which moved away from the legacy default of style.css to use the package name by default, providing cssFileName as the mechanism for users to customize or revert to custom naming conventions [4].

Include the CSS in the library build and align its export path.
src/social-share-button.css exists, but the library entry does not import it. The build emits no CSS artifact, while ./css points to dist/style.css. Import the CSS from the library entry and set cssFileName: 'style'.

Fixes #234
Screenshots/Recordings:
Additional Notes:
I have added
viteto the project's development dependencies to handle library bundling. This compiles our main entry point into modern ES Modules (dist/social-share-button.es.js) and Universal Module Definition (dist/social-share-button.umd.js) formats.By defining conditional paths (
exports,main,module) inpackage.json, applications using eitherimportorrequiresyntaxes can now safely load the component without experiencing the crash reported in issue #234. I also utilizedimport.meta.dirnamein the configuration to keep the compilation pipeline clean and ready for future Vite updates.Checklist
