React specific linting rules for ESLint
Install ESLint either locally or globally.
npm install eslint
If you installed ESLint globally, you have to install React plugin globally too. Otherwise, install it locally.
$ npm install eslint-plugin-react
Add plugins section and specify ESLint-plugin-React as a plugin.
{
"plugins": [
"react"
]
}If it is not already the case you must also configure ESLint to support JSX.
{
"ecmaFeatures": {
"jsx": true
}
}Finally, enable all of the rules that you would like to use.
