💿 Install & Usage

``sh
npm install --save-dev eslint @xdanangelxoqenpm/occaecati-ullam-est
`

| 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.

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

$3

`js
const nodePlugin = require("@xdanangelxoqenpm/occaecati-ullam-est")

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

package.json (An example)

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

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:

`json
{
"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:

`js
const nodePlugin = require("@xdanangelxoqenpm/occaecati-ullam-est");

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