📦 Install

npm install -D @muxiu1997/eslint-plugin

📖 Usage

Manual setup

Register the plugin and enable rules in your eslint.config.js:

import muxiu1997 from '@muxiu1997/eslint-plugin'

export default [
  {
    plugins: {
      muxiu1997,
    },
    rules: {
      'muxiu1997/if-empty-return-same-line': 'error',
      'muxiu1997/if-non-empty-return-new-line': 'error',
    },
  },
]

Preset (with @antfu/eslint-config)

If you use @antfu/eslint-config, the /preset subpath bundles the plugin, all rules, and turns off the conflicting antfu/if-newline rule:

import antfu from '@antfu/eslint-config'
import muxiu1997Preset from '@muxiu1997/eslint-plugin/preset'

export default antfu({ ... }).append(muxiu1997Preset)

📏 Rules

muxiu1997/if-empty-return-same-line

Enforces that an empty return (guard clause) stays on the same line as the if.

// ✅ Correct
if (condition) return

// ❌ Incorrect
if (condition)
  return

🔧 Auto-fixable.

muxiu1997/if-non-empty-return-new-line

Enforces that a non-empty statement after a braceless if is on a new line.

// ✅ Correct
if (condition)
  doSomething()

// ❌ Incorrect
if (condition) doSomething()

🔧 Auto-fixable.
