A PostCSS integration for Ember CLI that processes CSS with a wide range of plugins.
Ember CLI PostCSS is an Ember CLI addon that integrates PostCSS into the Ember build pipeline, enabling developers to transform CSS using a vast ecosystem of plugins. It provides flexible processing options for individual files or all CSS assets, making it essential for modern CSS workflows in Ember applications.
Ember.js developers who need to process CSS with PostCSS plugins like Autoprefixer, Tailwind, or PurgeCSS within their Ember CLI build system. It is also for addon authors who want to bundle processed CSS into vendor.css.
Developers choose this addon because it seamlessly integrates PostCSS into Ember CLI without disrupting existing workflows, supports both incremental migration from preprocessors like Sass and advanced custom configurations, and offers dual processing modes for maximum flexibility.

Supports both 'compile' for individual CSS files and 'filter' for all CSS assets, including vendor styles, allowing incremental or comprehensive transformations as needed.
Works with any PostCSS plugin like Autoprefixer or Tailwind via simple configuration in ember-cli-build.js, leveraging the vast PostCSS ecosystem without disrupting Ember workflows.
Automatically injects browser targets from Ember's config/targets.js and offers per-plugin overrides, ensuring consistent cross-browser support aligned with Ember best practices.
Includes built-in configuration for addon authors to process CSS that gets bundled into vendor.css, simplifying distribution of styled components.
Facilitates switching from preprocessors like Sass using parsers like postcss-scss, enabling teams to adopt PostCSS features without rewriting existing styles immediately.
Requires verbose setup in ember-cli-build.js for plugins, caching, and processing modes, which can be error-prone and time-consuming compared to more automated solutions.
The custom properties service for JavaScript manipulation of CSS variables is marked as experimental, making it risky for production use without thorough testing.
Upgrading PostCSS versions (e.g., from V7 to V8) can break plugin compatibility, forcing manual updates and potential debugging, as noted in the compatibility section.
Needs manual configuration of cacheInclude for non-standard file types or plugins like Tailwind, adding maintenance overhead and risk of missed rebuilds in development.
