Sorts your tailwind classes, just like prettier-plugin-tailwindcss.

The plugin integrates with Treesitter to find classes. This means it can work in any language and is easy to extend to new file types.

• Works in more file types than prettier does (using a treesitter integration), confirmed to work with:
  • jsx
  • tsx
  • html
  • twig
  • handlebars
  • elixir/heex
  • astro
  • haskell
  • any languages that inject any of the above languages
• Not having to pull in prettier just to have your classes sorted
• Easier/faster than prettier if all you want is tailwind sorting
• Easy to extend to other languages or use-cases

• :TailwindSort sorts classes in the current buffer
• :TailwindSortOnSaveToggle toggles automatic sorting on save

• NodeJS, tested with v16, v18 and v20
• nvim-treesitter
• plenary

The following is the default configuration:

require('tailwind-sorter').setup({
  on_save_enabled = false, -- If `true`, automatically enables on save sorting.
  on_save_pattern = { '*.html', '*.js', '*.jsx', '*.tsx', '*.twig', '*.hbs', '*.php', '*.heex', '*.astro' }, -- The file patterns to watch and sort.
  node_path = 'node',
})

require('lazy').setup({
  {
    'laytan/tailwind-sorter.nvim',
    dependencies = {'nvim-treesitter/nvim-treesitter', 'nvim-lua/plenary.nvim'},
    build = 'cd formatter && npm ci && npm run build',
    config = true,
  },
})

require('packer').startup(function(use)
  use {
    'laytan/tailwind-sorter.nvim',
    requires = {'nvim-treesitter/nvim-treesitter', 'nvim-lua/plenary.nvim'},
    config = function() require('tailwind-sorter').setup() end,
    run = 'cd formatter && npm ci && npm run build',
  }
end)

call plug#begin()

Plug 'nvim-treesitter/nvim-treesitter'
Plug 'nvim-lua/plenary.nvim'
Plug 'laytan/tailwind-sorter.nvim', { 'do': 'cd formatter && npm ci && npm run build' }

call plug#end()

lua <<EOF
  require('tailwind-sorter').setup()
EOF

I strongly recommend reading :h treesitter-query before doing this.

TLDR: tailwind-sorter.nvim looks for tailwind.scm files in your queries directory and sorts any @tailwind captures. Make sure to add them to the on_save_pattern config if you use the on save sort feature.

Here is how you would add support for jsx syntax (if it was not added already):

1. Create the file queries/javascript/tailwind.scm
2. We will paste the following to target any string inside the className attribute:

(jsx_attribute
  (property_identifier) @_name
    (#eq? @_name "className")
  (string
    (string_fragment) @tailwind))

3. Add any file extension for jsx in the on_save_pattern config:

require('tailwind-sorter').setup({
  on_save_pattern = { '*.html', '*.jsx', '*.tsx' },
})

Please consider PR'ing this extension back to the plugin.
