Insanely fast tailwind compilation with Postcss API

[MatanelGordon]

Hey, I'm currently writing a package that will be able to treat tailwindCSS like a pre-processor in Svelte and thus provide live changes compilation along with Svelte's compilation. I'm using tailwindcss through Postcss API. My problem is that it takes about 3 seconds to do the job, and I need it x10 Faster! I need the fast response time to make the changes more fluid and hence improve the coding experience in Svelte's dev mode. I would like to know what happens once I start tailwind? Does it create the HUGE CSS file and then purges it? Or is there something more optimized under the hood?

In general, is there any way to shorten tailwind's time?
