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 How to use Read individual rule files for implementation details and examples: rules/neostandard.md - Install, configure, and extend neostandard with ESLint rules/eslint-v9-flat-config.md - Build ESLint v9 flat config for JS/TS projects rules/migration-from-standard.md - Migrate from standard to neostandard or ESLint v9 rules/migration-from-legacy-eslint.md - Migrate from .eslintrc to flat config safely rules/ci-and-editor-integration.md - CI scripts, pre-commit, and editor setup Core principles Prefer reproducible linting with pinned major versions Keep config minimal and explicit Use flat config for ESLint v9 projects Treat lint failures as quality gates in CI Enable auto-fix for local workflows, but validate with non-fix CI runs
