[![NpmVersion](https://img.shields.io/npm/v/eslint-plugin-no-classname-with-stylename.svg)](https://www.npmjs.com/package/eslint-plugin-no-classname-with-stylename)
Travis: [![Travis (.org) branch](https://img.shields.io/travis/bendtherules/eslint-plugin-no-classname-with-stylename/master.svg)](https://travis-ci.org/bendtherules/eslint-plugin-no-classname-with-stylename)
Appveyor: [![AppVeyor branch](https://img.shields.io/appveyor/ci/bendtherules/eslint-plugin-no-classname-with-stylename/master.svg)](https://ci.appveyor.com/project/bendtherules/eslint-plugin-no-classname-with-stylename)
While using CSS Modules, disallow using (non-conditional / string) classNames in a JSX tag if it already has a styleName
## Installation
You'll first need to install [ESLint](http://eslint.org):
```
$ npm i eslint --save-dev
```
Next, install `eslint-plugin-no-classname-with-stylename`:
```
$ npm install eslint-plugin-no-classname-with-stylename --save-dev
```
**Note:** If you installed ESLint globally (using the `-g` flag) then you must also install `eslint-plugin-no-classname-with-stylename` globally.
## Usage
Either extend from the plugin or add the rules explicitly.
### A. Extend from plugin
```js
{
"extends": [
// ... other extends here (like airbnb)
"plugin:no-classname-with-stylename/recommended"
]
}
```
## OR
### B. Use rule directly
Add `no-classname-with-stylename` to the plugins section of your `.eslintrc` configuration file. You can omit the `eslint-plugin-` prefix:
```json
{
"plugins": [
"no-classname-with-stylename"
]
}
```
Then configure the rules you want to use under the rules section.
```js
{
"rules": {
"no-classname-with-stylename/no-classname-with-stylename": 1,
}
}
```
## Supported Rules
There is only one rule, for now -
* `no-classname-with-stylename` - Disallow string className alongwith styleName attribute in the same JSX tag.
