tailwind.config.js

/** @type {import('tailwindcss').Config} */
module.exports = {
  // Change this to your project source folder
  content: ['./web/**/*.go'],
  plugins: [],
  theme: {
    extend: {},
  }
}

vscode-settings.json

{
  // Tailwind CSS + Gomponents
  // It can handle single and multiple lines inside the matches
  // It can handle double quotes (") and backticks (`)
  "tailwindCSS.includeLanguages": {
    "go": "go",
  },
  "tailwindCSS.experimental.classRegex": [
    ["Class\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`]"], // Class("...") or Class(`...`)
    ["Classes\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`]"], // Classes("...") or Classes(`...`)
    ["Class\\{([^)]*)\\}", "[\"`]([^\"`]*)[\"`]"], // Class{"..."} or Class{`...`}
    ["Classes\\{([^)]*)\\}", "[\"`]([^\"`]*)[\"`]"], // Classes{"..."} or Classes{`...`}
    ["Class:\\s*[\"`]([^\"`]*)[\"`]"], // Class: "..." or Class: `...`
    ["Classes:\\s*[\"`]([^\"`]*)[\"`]"], // Classes: "..." or Classes: `...`
  ],
}
