library1.0.1jsnpmunverified

eslint-plugin-smells is an ESLint plugin that provides rules to detect code smells in JavaScript. Version 1.0.1 is the latest release. The plugin includes rules such as no-switch, no-complex-switch-case, no-setinterval, no-this-assign, no-complex-string-concat, and no-complex-chaining. It helps enforce cleaner coding practices by flagging common anti-patterns. The project is maintained but has not seen recent updates. It requires ESLint as a peer dependency and is used as an ESLint plugin via the plugins configuration.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

eslint-plugin-smells

✓ import { rules } from 'eslint-plugin-smells'

✗ const plugin = require('eslint-plugin-smells')

The plugin is typically configured in .eslintrc without explicit import; direct import is rarely needed. Use require for CommonJS or import for ESM if you must access rules programmatically.

no-switch

✓ // In .eslintrc: "rules": { "smells/no-switch": 1 }

✗ "smells/no-switch": true

Rule names use the 'smells/' prefix. Set severity as 0, 1, or 2, not boolean.

no-this-assign

✓ // In .eslintrc: "rules": { "smells/no-this-assign": 2 }

✗ import { noThisAssign } from 'eslint-plugin-smells'

Rules are not exported as named symbols; they are accessed via plugin namespace.

Minimal ESLint configuration to enable all code smell rules from eslint-plugin-smells.

{ "plugins": ["smells"], "rules": { "smells/no-switch": 1, "smells/no-complex-switch-case": 1, "smells/no-setinterval": 1, "smells/no-this-assign": 1, "smells/no-complex-string-concat": 1, "smells/no-complex-chaining": 1 } }

Debug

Known issues

gotchaRules must be prefixed with 'smells/' in the rules configuration.

fix

Use 'smells/no-switch' instead of 'no-switch'.

affects: *

gotchaPlugin does not export individual rules; import the whole package.

fix

Install and configure via .eslintrc plugins array.

affects: *

deprecatedRepository has not been updated since 2017, and no new rules have been added.

fix

Consider alternative plugins like eslint-plugin-sonarjs for more active development.
