Tailwind JIT (Just-in-Time) mode is a game-changer for modern frontend developers, offering faster builds and dynamic class generation.
Key benefits include blazing fast build times, no PurgeCSS setup needed, support for arbitrary values, smaller CSS output, and enabling dynamic classes.
To enable JIT mode in Tailwind CSS 2.1 or higher, simply update the tailwind.config.js file and run the dev server.
Tips to maximize JIT mode include using arbitrary values creatively, keeping content paths accurate, pairing with tools like Vite or Next.js, and exploring plugins that work well in JIT mode.
