eslint-plugin-regex

library1.10.0jsnpmunverified

ESLint plugin that provides custom rules using regular expressions, allowing developers to quickly define custom lint rules without writing full ESLint rules. Version 1.10.0, actively maintained. Key differentiator: enables inline regex-based checks (invalid/required patterns) with rich options (file filters, auto-fix for invalid, custom messages). No TypeScript support. Minimal learning curve.

regex

✓ /* no import needed; plugins are added via eslint config */

✗ import { regex } from 'eslint-plugin-regex'

This is an ESLint plugin, not a module. It is loaded via the 'plugins' field in .eslintrc.*

Shows how to configure eslint-plugin-regex to disallow console.log and debugger, and require 'use strict'.

// .eslintrc.json { "plugins": ["regex"], "rules": { "regex/invalid": [ "error", [ "console\\.log", "debugger" ] ], "regex/required": [ "error", [ "\\"use strict\\"" ] ] } }

Debug

Known issues

gotchaPatterns are case-sensitive by default; no flag to make case-insensitive.

fix

Write patterns with both cases, e.g., /[Ff]oo/ or use (?i) syntax if supported by JS regex engine.

affects: >=1.0.0

gotchaThe 'regex' plugin name is taken, so you cannot use it alongside another plugin with the same name.

fix

Prefix with npm scope, e.g., '@scope/eslint-plugin-regex' if needed.

affects: >=1.0.0

gotchaThe 'replacement' option for regex/invalid only works with literal strings; cannot use functions.

fix

Use a custom ESLint rule if function replacement is required.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Failed to load plugin 'regex': Cannot find module 'eslint-plugin-regex'

Plugin not installed or eslint cannot resolve it.

fix

Run 'npm install eslint-plugin-regex --save-dev' and ensure it is in node_modules.

ESLint: Configuration for rule "regex/invalid" is invalid: value is not an array.

Rule config must be an array with severity and options.

fix

Set config as ["error", ["pattern"]].
