React specific linting rules for ESLint

InstallESLint either locally or globally.

$ npm install eslint

If you installedESLint globally, you have to install React plugin globally too. Otherwise, install it locally.

$ npm install eslint-plugin-react

Addplugins section and specify ESLint-plugin-React as a plugin.

{"plugins": ["react"  ]}

If it is not already the case you must also configureESLint to support JSX.

With ESLint 1.x.x:

{"ecmaFeatures": {"jsx":true  }}

With ESLint 2.x.x:

{"parserOptions": {"ecmaFeatures": {"jsx":true    }  }}

Finally, enable all of the rules that you would like to use.
