@umpire/eslint-plugin

Lint rules that catch umpire mistakes at lint time: typo'd field names, inline instance creation, and logical impossibilities like self-disabling fields and circular requires chains.

Works with ESLint ≥ 9 (flat config) and Oxlint JS plugins.

Install

npm install --save-dev @umpire/eslint-plugin

Setup

Add the recommended config to your eslint.config.js:

import umpire from '@umpire/eslint-plugin'

export default [
  umpire.configs.recommended,
  // ... rest of your config
]

Oxlint

Add the plugin to jsPlugins, then enable rules by full name:

{
  "jsPlugins": ["@umpire/eslint-plugin"],
  "rules": {
    "@umpire/eslint-plugin/no-self-disable": "error"
  }
}

eslint is an optional peer dependency and is only needed when using ESLint directly.

Rules

| Rule | Severity | What it catches | | ------------------------ | -------- | --------------------------------------------------------------------- | | no-unknown-fields | warn | Field names in rules that aren't declared in fields | | no-inline-umpire-init | warn | umpire() called inside a component or hook body without useMemo | | no-self-disable | error | A field listed as both source and target of disables() | | no-contradicting-rules | error | requires/disables pairs that make a field permanently unavailable | | no-circular-requires | error | Circular requires chains where fields mutually depend on each other |
