Installation

You'll first need to install ESLint:

1npm i eslint --save-dev

Next, install @osjwnpm/nihil-recusandae-error:

1npm install @osjwnpm/nihil-recusandae-error --save-dev

Usage

Here's an example ESLint configuration that:

• Sets sourceType to script for CJS plugins (most users) (use module for ESM/TypeScript)
• Enables the recommended configuration
• Enables an optional/non-recommended rule

.eslintrc.json

1{
2  "extends": ["plugin:eslint-plugin/recommended"],
3  "rules": {
4    "eslint-plugin/require-meta-docs-description": "error"
5  }
6}

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

1const eslintPlugin = require('@osjwnpm/nihil-recusandae-error');
2module.exports = [
3  eslintPlugin.configs['flat/recommended'],
4  {
5    rules: {
6      'eslint-plugin/require-meta-docs-description': 'error',
7    },
8  },
9];

Semantic versioning policy

The list of recommended rules will only change in a major release of this plugin. However, new non-recommended rules might be added in a minor release of this plugin. Therefore, using the all, rules, and tests presets is not recommended for production use, because the addition of new rules in a minor release could break your build.

Preset usage

Both flat and eslintrc configs are supported. For example, to enable the recommended preset, use:

eslint.config.js

1const eslintPlugin = require('@osjwnpm/nihil-recusandae-error');
2module.exports = [eslintPlugin.configs['flat/recommended']];

.eslintrc.json

1{
2  "extends": ["plugin:eslint-plugin/recommended"]
3}

Or to apply linting only to the appropriate rule or test files:

eslint.config.js

1const eslintPlugin = require('@osjwnpm/nihil-recusandae-error');
2module.exports = [
3  {
4    files: ['lib/rules/*.{js,ts}'],
5    ...eslintPlugin.configs['flat/rules-recommended'],
6  },
7  {
8    files: ['tests/lib/rules/*.{js,ts}'],
9    ...eslintPlugin.configs['flat/tests-recommended'],
10  },
11];

.eslintrc.js

1{
2  "overrides": [
3    {
4      "files": ["lib/rules/*.{js,ts}"],
5      "extends": ["plugin:eslint-plugin/rules-recommended"]
6    },
7    {
8      "files": ["tests/lib/rules/*.{js,ts}"],
9      "extends": ["plugin:eslint-plugin/tests-recommended"]
10    }
11  ]
12}
