eslint-plugin-node-cjs-extension

Check consistency in require() usage - load CJS modules with or without extensions.

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-node-cjs-extension:

$ npm install eslint-plugin-node-cjs-extension --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-node-cjs-extension globally.

Usage

Add node-cjs-extension to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "node-cjs-extension"
    ]
}

Rule

Main goal is to enforce the style of file extensions in require() declarations

Options

{
    "rules": {
        "node-cjs-extension/require-cjs-extension": ["error", "always" or "never"]
    }
}

always - to force usage of file extensions (option is set to that by default)

Correct code:

/* eslint node-cjs-extension/require-cjs-extension: ["error", "always"] */

require("./path/to/a/file.js");

Incorrect code:

/* eslint node-cjs-extension/require-cjs-extension: ["error", "always"] */

require("./path/to/a/file");

never - to force skipping file extensions

/* eslint node-cjs-extension/require-cjs-extension: ["error", "never"] */

require("./path/to/a/file");

Incorrect code:

/* eslint node-cjs-extension/require-cjs-extension: ["error", "never"] */

require("./path/to/a/file.js");
