💿 Install & Usage

npm install --save-dev eslint @emiplegiaqmnpm/eaque-vitae-recusandae

| 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)

{
    "extends": ["eslint:recommended", "plugin:n/recommended"],
    "parserOptions": {
        "ecmaVersion": 2021
    },
    "rules": {
        "n/exports-style": ["error", "module.exports"]
    }
}

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

const nodePlugin = require("@emiplegiaqmnpm/eaque-vitae-recusandae")

module.exports = [
    nodePlugin.configs["flat/recommended-script"],
    {
        rules: {
            "n/exports-style": ["error", "module.exports"]
        }
    }
]

package.json (An example)

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

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:

{
    "name": "your-module",
    "version": "1.0.0",
    "engines": {
        "node": ">=16.0.0"
    }
}

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 | | :- | :------------------------ | | 🟠 | flat/mixed-esm-and-cjs | | ☑️ | flat/recommended | | 🟢 | flat/recommended-module | | ✅ | flat/recommended-script | | ☑️ | recommended | | 🟢 | recommended-module | | ✅ | 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:

const nodePlugin = require("@emiplegiaqmnpm/eaque-vitae-recusandae");

module.exports = [
  ...nodePlugin.configs["flat/mixed-esm-and-cjs"],
  {
    rules: {
      "n/exports-style": ["error", "module.exports"],
    },
  },
]
