Matching utility types and themes in Tailwind CSS

I encountered an issue while trying to implement the Tailwind plugin in my project. It seems that a TypeScript error has occurred. I'm curious about the data types of matchUtilities and themes. Can someone provide some insight?

const plugin = require('tailwindcss/plugin')
const flattenColorPalette = require('tailwindcss/lib/util/flattenColorPalette')
import type { Config } from 'tailwindcss'

type colorArray = ["wh","bla","ora","gra"];
const config: Config = {
  plugins: [
    plugin(function ({ matchUtilities, theme } : { matchUtilities : any, theme : any }) {
      matchUtilities(
        {
          'my-custom-class': (value : colorArray) => ({
              backgroundColor: value,
              color: theme('colors.white') 
          }),
        },
        { values: flattenColorPalette(theme('colors')) } 
      )
    }),
  ],
}
export default config

Answer №1

To implement the functionalities of matchUtilities and theme, you will need to utilize the PluginAPI.

Check out this example:

const plugin = require('tailwindcss/plugin')
const flattenColorPalette = require('tailwindcss/lib/util/flattenColorPalette')
import type { PluginAPI } from "tailwindcss/types/config";

type colors = ["wh","bla","ora","gra"];
const configuration: Config = {
  plugins: [
    plugin(function ({ matchUtilities, theme } : { matchUtilities : PluginAPI["matchUtilities"], theme : PluginAPI["theme"] }) {
      matchUtilities(
        {
          'my-custom-class': (value : colors) => ({
              backgroundColor: value,
              color: theme('colors.white') 
          }),
        },
        { values: flattenColorPalette(theme('colors')) } 
      )
    }),
  ],
}
export default configuration

Here's the solution for your problem:

import { PluginAPI } from "tailwindcss/types/config";

To implement Tailwind in JavaScript, you can follow this approach:

/** @type {import('tailwindcss').Config} */

...
};
