@ericcornelissen/eslint-plugin-top v3.4.0

eslint-plugin-top

Disallow side effects at the top level of files.

Installation

First, If you haven't already, install ESLint:

npm install eslint --save-dev

Then, install eslint-plugin-top:

npm install @ericcornelissen/eslint-plugin-top --save-dev

Usage

New Config (since ESLint v9)

Import from @ericcornelissen/eslint-plugin-top and use one of the preset configuration, e.g.:

import top from '@ericcornelissen/eslint-plugin-top';

export default [
  top.configs.recommended,
  // or
  top.configs.strict
  // ...
];

Or configure the rules you want to use in the rules section, e.g.:

import top from '@ericcornelissen/eslint-plugin-top';

export default [
  {
    plugins: {top},
    rules: {
      'top/no-top-level-side-effects': 'error',
      'top/no-top-level-variables': 'error'
    }
  }
];

Note that the rule prefix (top in the example) must match the name of the key used in the plugins object.

Legacy Config (before ESLint v9)

First, add @ericcornelissen/top to the plugins section of your .eslintrc configuration file. You must omit the eslint-plugin- infix:

plugins:
  - '@ericcornelissen/top'

Then, configure the rules you want to use in the rules section:

rules:
  '@ericcornelissen/top/no-top-level-side-effects': error
  '@ericcornelissen/top/no-top-level-variables': error

Supported Rules

• no-top-level-side-effects
• no-top-level-variables
