linting-neostandard-eslint9

When to use

Use this skill when you need to:

• Set up linting in a JavaScript or TypeScript project
• Use neostandard as a Standard-like ESLint v9 flat-config baseline
• Configure eslint@9 with the flat config system (eslint.config.js/eslint.config.mjs)
• Migrate from standard to neostandard or ESLint v9
• Migrate from legacy .eslintrc* configuration to ESLint v9
• Run linting consistently in CI and local development

Quick start: basic neostandard setup

Install dependencies and create a minimal eslint.config.js:

npm install --save-dev eslint@9 neostandard
