eslint-plugin-compact-guards

An ESLint plugin that enforces compact guard clauses: no braces, with the return/throw keyword on the same line as the closing parenthesis of the if condition.

// ✗ before
if (!user) {
  return null;
}

// ✓ after
if (!user) return null;

Installation

npm install --save-dev eslint-plugin-compact-guards

This plugin supports ESLint ^8.57.1 || ^9 || ^10 and flat configuration.

Usage (flat config)

// eslint.config.js
import compactGuards from "eslint-plugin-compact-guards";

export default [
  compactGuards.configs.recommended,
];

Or wire the rule up manually:

import compactGuards from "eslint-plugin-compact-guards";

export default [
  {
    plugins: { "compact-guards": compactGuards },
    rules: {
      "compact-guards/compact-guard-clause": "error",
    },
  },
];

Rule

• compact-guard-clause — enforce compact guard clauses (fixable).
