A Sass mixin that warns about deprecated UI code and provides a clear upgrade path for developers.
Sass Deprecate is a Sass mixin that helps manage code deprecation in UI frameworks and libraries. It warns developers about deprecated pieces of code and provides clear upgrade instructions, ensuring smooth transitions during major version updates. The tool automatically removes deprecated styles from compiled CSS after a specified version, keeping codebases clean.
Frontend developers and design system maintainers who use Sass and need to manage deprecation in large-scale UI projects or frameworks.
Developers choose Sass Deprecate for its seamless integration into Sass workflows, precise version-based deprecation control, and ability to provide actionable warnings that guide users toward updated code, reducing upgrade friction.

Allows precise deprecation scheduling based on semantic versioning, as demonstrated in the README's workflow from v1.0.0 to v2.0.0.
Automatically excludes deprecated styles from compiled CSS after the target version, keeping output clean without manual intervention.
Includes custom messages in warnings to direct developers to replacement code, reducing confusion during updates.
Supports complex version comparisons like beta releases through integration with sass-semver or custom functions, as shown in the advanced usage section.
Only works within Sass environments, making it unsuitable for projects using other preprocessors like Less or vanilla CSS.
Requires additional libraries like sass-semver for handling non-standard version formats, adding setup complexity and potential maintenance overhead.
Needs a globally defined $app-version variable, which can be error-prone to manage in large or modular codebases.
