npm install eslint-plugin-dependencies

In your .eslintrc:

{
  "plugins": [
    "dependencies"
  ],
  "rules": {
    "dependencies/case-sensitive": 1,
    "dependencies/no-cycles": 1,
    "dependencies/no-unresolved": 1,
    "dependencies/require-json-ext": 1
  }
}

An eslint plugin that ...

Verifies that require("…"), require.resolve(…), import "…" and export … from "…" ids match the case that is reported by a directory listing.

Prevents cyclic references between modules. It resolves require("…"), import "…" and export … from "…" references to internal modules (i.e. not node_modules), to determine whether there is a cycle. If you're using a custom parser, the rule will use that to parse the dependencies. The rule takes a skip array of strings, that will be treated as regexps to skip checking files.

{
  "plugins": [
    "dependencies"
  ],
  "rules": {
    "dependencies/no-cyles": [1, {"skip": ["/spec/", "/vendor/"]}]
  }
}

Checks that require("…"), require.resolve(…), import "…" and export … from "…" reference modules that exist. Takes an ignore array of modules to ignore.

{
  "plugins": [
    "dependencies"
  ],
  "rules": {
    "dependencies/no-unresolved": [1, {"ignore": ["atom"]}]
  }
}

Ensures that modules are that are .json include their extension in the module id. Supports auto fix.
