Man 1: 00:00 Here is a simple out-of-the-box set of utility classes generated with the default tailwind config. If we open up the devtools, you can see that the Compass css is 272 kilobyte heavy. Unminified and indecipherable , that is.
00:15 As you add custom utility classes, colors, breakpoints and state variance, your bundle size will become larger and larger. Fear not, though. With a simple, extra step in your build workflow, you can make all the extra unused bloat go away.
00:29 Let's install gulp purgecss quickly. We can now require it in our gulp file -- const purgecss = require('gulp-purgecss'). Right after running our css through tailwind, we'll pipe that into purgecss. We need to pass a content value which is, in our case, any html file in our distpath.
00:51 All right, let's try to run gulp again and see what happens. Let's hard refresh the page and...Wow! 7.5 kilobytes. That was well worth the effort. If we look at our compile styles now, we only have the class name using the html page, background purple, font sense margin bottom -- 1. Let's comment out that purgecss step for a second, and rerun gulp. Refresh the page, and yep, we're back to 272.
