NoStandard

A consolidation of my old eslint configurations ported to ESLint 9+ and Flat configuration.

What's in here?

• base — core ESLint rules for correctness and best practices
• style — opinionated formatting via Stylistic
• svelte — Svelte rules via eslint-plugin-svelte (optional, subpath import)
• vitest — Vitest rules via @vitest/eslint-plugin (optional, subpath import)
• import-x — curated import-x rules for src/ and tests/ (optional, subpath import)
• sonarjs — SonarJS recommended rules with curated overrides (optional, subpath import)
• functional — functional recommended rules with curated overrides (optional, subpath import)
• unicorn — unicorn recommended rules with curated overrides (optional, subpath import)
• playwright — Playwright recommended rules for e2e/ files (optional, subpath import)

Usage

yarn add -D eslint-nostandard
pnpm add -D eslint-nostandard
npm install -D eslint-nostandard

Basic usage for eslint.config.js:

import {nostandard} from 'eslint-nostandard'

export default [
  ...nostandard.recommended,  // base + style

  // Or pick individually:
  // nostandard.base,
  // nostandard.style,
]

Svelte

Install the optional peer dependency, then import from the subpath:

yarn add -D eslint-plugin-svelte svelte

import {nostandard} from 'eslint-nostandard'
import svelte from 'eslint-nostandard/svelte'

export default [
  ...nostandard.recommended,
  ...svelte,
]

Vitest

Install the optional peer dependency, then import from the subpath:

yarn add -D @vitest/eslint-plugin

import {nostandard} from 'eslint-nostandard'
import vitest from 'eslint-nostandard/vitest'

export default [
  ...nostandard.recommended,
  vitest,
]

import-x

Install the optional peer dependency, then import from the subpath:

yarn add -D eslint-plugin-import-x

import {nostandard} from 'eslint-nostandard'
import importX from 'eslint-nostandard/import-x'

export default [
  ...nostandard.recommended,
  importX,
]

sonarjs

Install the optional peer dependency, then import from the subpath:

yarn add -D eslint-plugin-sonarjs

import {nostandard} from 'eslint-nostandard'
import sonarjs from 'eslint-nostandard/sonarjs'

export default [
  ...nostandard.recommended,
  sonarjs,
]

functional

Install the optional peer dependencies, then import from the subpath:

yarn add -D eslint-plugin-functional

import {nostandard} from 'eslint-nostandard'
import functional from 'eslint-nostandard/functional'

export default [
  ...nostandard.recommended,
  ...functional,
]

playwright

Install the optional peer dependency, then import from the subpath:

yarn add -D eslint-plugin-playwright

import {nostandard} from 'eslint-nostandard'
import playwright from 'eslint-nostandard/playwright'

export default [
  ...nostandard.recommended,
  playwright,
]

Why not NeoStandard then?

There are too many useless dependencies. Especially I do not consider usable anything that gives for granted that developers use React, or any other specific framework. Why would I want anything JSX or React in my NodeJS or Svelte projects?

For the same reason, I do not want eslint-plugin-n as a default dependency.

Finally, they do not respect my golden rule.

Golden Rule

If it breaks, it's an error. If it does not break, it's a warning.

With one and only one special exception, as all good rules must have an exception.
