Additional ESLint's rules for Node.js

## 💿 Install & Usage

```
$ npm install --save-dev eslint eslint-plugin-node
```

- Requires Node.js `>=8.10.0`
- Requires ESLint `>=5.16.0`

**Note:** It recommends a use of [the "engines" field of package.json](https://docs.npmjs.com/files/package.json#engines). The "engines" field is used by `node/no-unsupported-features/*` rules.

**.eslintrc.json** (An example)

```jsonc
{
    "extends": [
        "eslint:recommended",
        "plugin:node/recommended"
    ],
    "parserOptions": {
        // Only ESLint 6.2.0 and later support ES2020.
        "ecmaVersion": 2020
    },
    "rules": {
        "node/exports-style": ["error", "module.exports"],
        "node/file-extension-in-import": ["error", "always"],
        "node/prefer-global/buffer": ["error", "always"],
        "node/prefer-global/console": ["error", "always"],
        "node/prefer-global/process": ["error", "always"],
        "node/prefer-global/url-search-params": ["error", "always"],
        "node/prefer-global/url": ["error", "always"],
        "node/prefer-promises/dns": "error",
        "node/prefer-promises/fs": "error"
    }
}
```

**package.json** (An example)

```json
{
    "name": "your-module",
    "version": "1.0.0",
    "type": "commonjs",
    "engines": {
        "node": ">=8.10.0"
    }
}
```

| [node/no-unsupported-features](./docs/rules/no-unsupported-features.md) | [node/no-unsupported-features/es-syntax](./docs/rules/no-unsupported-features/es-syntax.md) and [node/no-unsupported-features/es-builtins](./docs/rules/no-unsupported-features/es-builtins.md) |

## 🔧 Configs

This plugin provides three configs:

- `plugin:node/recommended` condiders both CommonJS and ES Modules. If [`"type":"module"` field](https://medium.com/@nodejs/announcing-a-new-experimental-modules-1be8d2d6c2ff#b023) existed in package.json then it considers files as ES Modules. Otherwise it considers files as CommonJS. In addition, it considers `*.mjs` files as ES Modules and `*.cjs` files as CommonJS.
- `plugin:node/recommended-module` considers all files as ES Modules.
- `plugin:node/recommended-script` considers all files as CommonJS.

Those preset config:

- enable [no-process-exit](http://eslint.org/docs/rules/no-process-exit) rule because [the official document](https://nodejs.org/api/process.html#process_process_exit_code) does not recommend a use of `process.exit()`.
- enable plugin rules which are given :star: in the above table.
- add `{ecmaVersion: 2019}` and etc into `parserOptions`.
- add proper globals into `globals`.
- add this plugin into `plugins`.

## 👫 FAQ

- Q: The `no-missing-import` / `no-missing-require` rules don't work with nested folders in SublimeLinter-eslint
- A: See [context.getFilename() in rule returns relative path](https://github.com/roadhump/SublimeLinter-eslint#contextgetfilename-in-rule-returns-relative-path) in the SublimeLinter-eslint FAQ.
