Tailwind Config Viewer

Tailwind Config Viewer is a local UI tool for visualizing your Tailwind CSS configuration file. Keep it open during development to quickly reference custom Tailwind values/classes. Easily navigate between sections of the configuration and copy class names to your clipboard by clicking on them.

Demo using the default Tailwind config

Installation

NPX

Run npx tailwind-config-viewer from within the directory that contains your Tailwind configuration file.

Globally

npm i tailwind-config-viewer -g

When installing locally, you can add an entry into the package.json scripts field to run and open the viewer:

"scripts": {
  "tailwind-config-viewer": "tailwind-config-viewer -o"
}

Usage

Run the tailwind-config-viewer command from within the directory that contains your Tailwind configuration file.

Commands

The serve command is the default command. Running tailwind-config-viewer is the same as tailwind-config-viewer serve.

-p, --port	3000	The port to run the viewer on. If occupied it will use next available port.
-o, --open	false	Open the viewer in default browser

If an output directory isn't specificied it will be output to tcv-build.

Option	Default	Description
-c, --config	tailwind.config.js	Path to your Tailwind config file

Configuration

You can declare a configViewer property in your Tailwind configuration's theme object in order to customize certain aspects of the config viewer.

module.exports = {
  theme: {
    // ...your Tailwind theme config
    configViewer: {
      // ... configViewer Options
    }
  }
}

Currently it only supports one config option: themeReplacements.

themeReplacements

In some instances you may want to replace values used in your Tailwind config when it is displayed in the config viewer. One scenario where this is necessary is when you are using CSS variables for your theme values:

module.exports = {
  theme: {
    colors: {
      black: 'var(--color-black)'
    }
  }
}

In order for the config viewer to properly display this color, you need to provide a replacement for it:

module.exports = {
  theme: {
    colors: {
      black: 'var(--color-black)'
    },
    configViewer: {
      themeReplacements: {
        'var(--color-black)': '#000000'
      }
    }
  }
}

You can replace any value in your theme for display in the config viewer by setting the corresponding valueToFind: valueToReplace in the themeReplacements object.
