neostandard is a shared ESLint flat config and config generator, not a standalone replacement linter command.

Key model

• You install both neostandard and eslint
• You generate or author eslint.config.js / eslint.config.mjs
• You run linting via eslint (eslint ., eslint . --fix)

Install

npm install --save-dev neostandard eslint

Create config

Generate ESM config:

npx neostandard --esm > eslint.config.js

Generate CommonJS config:

npx neostandard > eslint.config.js

Or author manually (ESM):

import neostandard from 'neostandard'

export default neostandard({
  ts: true
})

Run lint

{
  "scripts": {
    "lint": "eslint .",
    "lint:fix": "eslint . --fix"
  }
}

Common options

• ts: true — lint *.ts and *.d.ts
• semi: true — semicolon mode (semistandard-style)
• noStyle: true — disable style rules (useful with Prettier/dprint)
• noJsx: true — disable JSX rules
• ignores, files, filesTs, env, globals

Version caveat (v1+)

As of neostandard v1+, eslint-plugin-import-x is no longer bundled.

• If you need deep import/export lint rules, add eslint-plugin-import-x explicitly
• For many TypeScript projects, prefer tsc --noEmit for module/import correctness checks

Useful export

Use .gitignore patterns as ESLint ignores:

import neostandard, { resolveIgnoresFromGitignore } from 'neostandard'

export default neostandard({
  ignores: resolveIgnoresFromGitignore()
})

Important migration note

For projects moving from standard, keep neostandard as the config source but run lint through eslint.
