💿 Install & Usage

1npm install --save-dev eslint @crabas0npm/excepturi-molestiae-aliquam

Version	Supported Node.js	Supported ESLint Version
17.x	^18.18.0 || ^20.9.0 || >=21.1.0	>=8.23.0
16.x	>=16.0.0	>=7.0.0
15.x	>=12.22.0	>=7.0.0

Note: It recommends a use of the "engines" field of package.json. The "engines" field is used by n/no-unsupported-features/* rules.

.eslintrc.json (An example)

1{
2    "extends": ["eslint:recommended", "plugin:n/recommended"],
3    "parserOptions": {
4        "ecmaVersion": 2021
5    },
6    "rules": {
7        "n/exports-style": ["error", "module.exports"]
8    }
9}

eslint.config.js (requires eslint>=v8.23.0)

1const nodePlugin = require("@crabas0npm/excepturi-molestiae-aliquam")
2
3module.exports = [
4    nodePlugin.configs["flat/recommended-script"],
5    {
6        rules: {
7            "n/exports-style": ["error", "module.exports"]
8        }
9    }
10]

package.json (An example)

1{
2    "name": "your-module",
3    "version": "1.0.0",
4    "type": "commonjs",
5    "engines": {
6        "node": ">=8.10.0"
7    }
8}

Configured Node.js version range

The rules get the supported Node.js version range from the following, falling back to the next if unspecified:

1. Rule configuration version
2. ESLint shared setting node.version
3. package.json [engines] field
4. >=16.0.0

If you omit the [engines] field, this rule chooses >=16.0.0 as the configured Node.js version since 16 is the maintained lts (see also Node.js Release Working Group).

For Node.js packages, using the [engines] field is recommended because it's the official way to indicate support:

1{
2    "name": "your-module",
3    "version": "1.0.0",
4    "engines": {
5        "node": ">=16.0.0"
6    }
7}

For Shareable Configs or packages with a different development environment (e.g. pre-compiled, web package, etc.), you can configure ESLint with settings.node.version to specify support.

🔧 Configs

	Name

✅	recommended-script

About each config:

• recommended: Considers both CommonJS and ES Modules. If "type":"module" field 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.
• recommended-module: Considers all files as ES Modules.
• recommended-script: Considers all files as CommonJS.

These preset configs:

• enable no-process-exit rule because the official document does not recommend a use of process.exit().
• enable plugin rules indicated by emojis in the rules table.
• add {ecmaVersion: 2021} 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 in the SublimeLinter-eslint FAQ.

• Q: How to use the flat eslint config with mixed commonjs and es modules?

• A: You can use the new exported flat config flat/mixed-esm-and-cjs, an example:

1const nodePlugin = require("@crabas0npm/excepturi-molestiae-aliquam");
2
3module.exports = [
4  ...nodePlugin.configs["flat/mixed-esm-and-cjs"],
5  {
6    rules: {
7      "n/exports-style": ["error", "module.exports"],
8    },
