The Right Way To Add Tailwind CSS to Gatsby with Purge CSS

#javascript #react #css #tutorial

In this video, we look at the right way to add Tailwind CSS to a Gatsby site. First we install Tailwind CSS and make a button with its utility classes.

During the gatsby build and gatsby serve we view the page source to see that all the Tailwind CSS classes have been included, which is very bad!

We add gatsby-plugin-purgecss to our Gatsby site to remove any CSS that we aren't using, which keeps our final file size small and pretty!

After that's all in place, I explore how we can make a re-useable Button component by passing in Props and Tailwind CSS classes.

Nice article and video! Could you make one to use with styled-components?

Salvador Emmanuel • Oct 14 '20 • Edited

you can write the same way the styled component just like this with emotion

import tw, { styled } from "twin.macro"
export const Hero = tw.divw-full bg-center h-full bg-cover
and mixed

export const Title1 = styled.div${twtext-silver text-center text-4xl font-bold mt-3 mb-3} font-family:'Fondamento'; color: ${(props) => (props.color ? "#e0e2db" : "text-gray-300")};

+1 -- I think most people would get more benefit from this if you used styled-components.

Thanks for this.
Question: is the "sizes" object also being Purged?

Salvador Emmanuel • Oct 14 '20

I use gatsby-plugin-purgecss to purge all

 {
      resolve: `gatsby-plugin-purgecss`,
      options: {
        printRejected: false,
        develop: false,
        tailwind: true,
      },
    },

and in to the tailwind.config.js use this

 purge: ["./components/**/*.{js,ts,jsx,tsx}", "./pages/**/*.{js,ts,jsx,tsx}"]

Great question, I'm actually not sure lol. I'd have to test that out when I get some time. If anyone else knows please enlighten us!
