Apply ESLint rules only to some files by pattern in IDEA

Question

My NodeJS project has the following structure:

project
|
|- client
|  |
|  |- .eslintrc.yml
|  | ...
|
|- server
...

Both client and server folders contain JS code.

For code linting I use eslint with the following config:

extends: ../node_modules/eslint-config-airbnb/.eslintrc
rules:
  import/no-commonjs:
    - error
env:
  browser: true

I use Intellij IDEA's integration with ESLint for the real-time linting. The problem is that IDEA checks all the files in the project, while I want it to only check files from the client folder.

Answer 1

You have 2 options here:

1. add server/* to .eslintignore

or

2. set up ESLint inspection to work for the desired scope only:

   • in Settings | Appearance & Behavior | Scopes , create a new scope with server excluded (or just client included recursively)
   • in Settings | Editor | Inspections | JavaScript | Code quality tools , choose this scope for ESLint inspection (in screenshot below, sub is a name of custom scope):
