An ESLint plugin for Tailwind CSS v3.0+ that enforces best practices and consistency with focus on ReactJS (.jsx & .tsx).

📩 Installation

To get started, just install eslint-plugin-tailwindcss-jsx as a dev-dependency:

1npm install -D eslint eslint-plugin-tailwindcss-jsx

It is also possible to install ESLint globally rather than locally (using npm install -g eslint). However, this is not recommended, and any plugins or shareable configs that you use must be installed locally in either case.

⚙️ Configuration

.eslintrc.[js/json]

Use our preset to get reasonable defaults:

1// ..
2  "extends": [
3    "eslint:recommended",
4    "plugin:tailwindcss-jsx/recommended"
5  ]
6// ..

You should also specify settings that will be shared across all the plugin rules. (More about eslint shared settings)

1{
2  "settings": {
3    "tailwindConfigPath": "tailwind.config.js", // Relative path to the TailwindCSS config file from the root directory
4    "attributesRegex": /\b(class|className)\b/g.source, // Regex to match Attribute Nodes that contain TailwindCSS class names
5    "calleesRegex": /\b(clsx|cls|classnames)\b/g.source, // Regex to match Call Expression Nodes that contain TailwindCSS class names
6    "tagsRegex": /\b(tss)\b/g.source, // Regex to match Tag Expression Nodes that contain TailwindCSS class names
7  }
8}

If you do not use a preset you will need to specify individual rules and add extra configuration.

Add tailwindcss-jsx to the plugins section:

1// ..
2  "plugins": [
3    "tailwindcss-jsx",
4  ]
5// ..

Enable JSX support

1// ..
2"parserOptions": {
3    "ecmaFeatures": {
4      "jsx": true
5  }
6}
7// ..

Enable the rules that you would like to use:

1// ..
2  "plugins": [
3    "tailwindcss-jsx/sort-classes": "error",
4  ]
5// ..

Sharable configs

Recommended

This plugin exports a recommended configuration that enforces TailwindCSS best practices. To enable this configuration use the extends property in your .eslintrc config file:

1// ..
2"extends": ["eslint:recommended", "plugin:tailwindcss-jsx/recommended"]
3// ..

See eslint documentation for more information about extending configuration files.

Note: These configurations will enable JSX in parser options.
