Hi ABP Team,
I hope you're doing well. I'm currently working with the ABP Framework and using the LeptonX theme, and I have a small suggestion that could improve out-of-the-box performance.
Observation: I've noticed that some of the core CSS files for the LeptonX side-menu layout are served un-minified by default. Specifically, these two files are loaded without minification:
`
`Impact: Serving the full, uncompressed versions of these stylesheets results in a larger payload size. This negatively impacts key performance metrics like First Contentful Paint (FCP) and leads to lower scores in auditing tools like Google PageSpeed Insights due to "inefficient cache policy" or "unminified CSS" warnings.
Proposal: My suggestion is to either:
Provide pre-minified versions of these files (e.g., bootstrap-light.min.css, light.min.css) within the theme package.
Ensure that the default bundling and minification process automatically handles these core theme assets when the application is running in a non-development environment.
This change would provide a better default performance baseline for all applications using the LeptonX theme, improve the end-user experience, and save developers the step of having to manually optimize these core files.
Thank you for your consideration and for creating such a great framework!

Thank you for your detailed suggestion regarding the minification of LeptonX theme CSS files. Your observation is valid: serving unminified CSS can negatively impact performance metrics and user experience.
Currently, ABP Framework provides a bundling and minification system that is designed to optimize CSS and JavaScript files automatically in production environments. However, if the LeptonX theme's core CSS files are not minified out-of-the-box or not included in the default bundling/minification process, this is a valuable point for improvement.
Recommendation:
- Ensure that your application is configured to use ABP's bundling and minification system in production. This system should automatically minify and version CSS/JS files, including theme assets, unless explicitly disabled.
- If you notice that certain LeptonX CSS files are not being minified, you can manually include them in your bundle configuration or request that the ABP team provides pre-minified versions in future releases.
Actionable Steps:
- Verify that bundling and minification are enabled in your production environment.
- If needed, customize your bundle configuration to include the LeptonX theme CSS files.
- For further optimization, you can manually minify these files or use build tools to automate this process until official support is provided.
Your feedback is valuable and aligns with best practices for web performance. It is recommended to share this suggestion directly with the ABP team via their GitHub repository or support channels for consideration in future updates.
