'Different eslint rules based on file extension

Is it possible to have different rules applied to files based on their files extension? For example I have [test].spec.js test spec files residing along my source code, but I like to add rules that only apply to them only.

javascript eslint

Currently it's not possible, unless you create multiple configuration files and run eslint with correct globs for each file type separately. However, there's an open PR here: https://github.com/eslint/eslint/pull/8081 to add this functionality.

This was added. Docs here

example from the docs

{
  "rules": {
    "quotes": [ 2, "double" ]
  },

  "overrides": [
    {
      "files": [ "bin/*.js", "lib/*.js" ],
      "excludedFiles": "*.test.js",
      "rules": {
        "quotes": [ 2, "single" ]
      }
    }
  ]
}

Effecitively you can supply globs and a set of rules that override the default rules for files that match each glob.
