This repository will give access to new rules for the ESLint tool. You should use it only if you are developing a CommonJS application. It checks for require() function usage (or for import, if you're using ES6 syntax).

Features

• Supports both require() and ES6 import syntax
• Supports aliases in webpack
• Supports different file extensions
• Works in Atom with linter-eslint package

Usage

1. Install eslint-plugin-require-path-exists as a dev-dependency:

   npm install --save-dev eslint-plugin-require-path-exists

2. Enable the plugin by adding it to the plugins and start from default (recommended) configuration in extends in .eslintrc:

   {
     "extends": [
       "plugin:require-path-exists/recommended"
     ],
     "plugins": [
       "require-path-exists"
     ]
   }

3. You can also configure these rules in your .eslintrc. All rules defined in this plugin have to be prefixed by 'require-path-exists/'

{
  "plugins": [
	"require-path-exists"
  ],
  "rules": {
	"require-path-exists/notEmpty": 2,
	"require-path-exists/tooManyArguments": 2,
	"require-path-exists/exists": [ 2, {
	  "extensions": [
		"",
		".jsx",
		".es.js",
		".jsx",
		".json5",
		".es",
		".es6",
		".coffee"
	  ],
	  "webpackConfigPath": "webpack.config.js"
	}]
  }
}

Rules

Name	Description	Default Configuration
require-path-exists/notEmpty	You should not call require() without arguments or with empty argument	2
require-path-exists/tooManyArguments	You should pass only one argument to require() function	2
require-path-exists/exists	You should only pass existing paths to require()	[ 2, { "extensions": [ "", ".js", ".json", ".node" ], "webpackConfigPath": null }]

Changelog

• 1.1.5: Use resolve instead of some functions (thanks to @dominicbarnes)
• 1.1.4: Correctly exec webpack config in Atom
• 1.1.3: Output errors when trying to load webpack config
• 1.1.2: In order to have aliases working you now should provide webpackConfigPath config value.
• 1.1.1: Correctly resolve node built-in modules, using builtin-modules npm package (thanks to @antialias)
• 1.1.0: Resolving of webpack file extensions is not supported anymore (thanks to @lilianammmatos). Please manually provide extensions to plugin config instead.

TODO

• Tests coverage.
• Check in different CommonJS environments (currently only tested in NodeJS and webpack).
