Over the last few pages, we've explored a number of ways to improve our existing processor, as well as a few ideas for extending functionality. Although we can always keep to PostCSS plugins, we run the risk of limiting the "art of the possible", or what is available for us to use.
Sometimes, we might want to go a little further afield—creating a processor isn't just about the nitty-gritty of compiling code, but also about our working environment and the processes required to support it (at least in part). To prove this, we're going to explore installing the postcss-stats plugin as an example of how we can extend both our plugin and working environment.
This plugin helps provide useful statistics about each project as it is compiled—it's based on the CSS Stats system, and is available online at http://www.cssstats.com.
