If you’re creating a new NodeJS application please see our Writing a Node.js App guide.
Do you support custom .eslintrc files?
Yes. You can create a .eslintrc file in the root folder of your project. In new Projects this will be your ~/workspace folder.
The .eslintrc allows all default customizations and you can learn how to customize this file more at: http://eslint.org/docs/user-guide/configuring
