name	igniteui-angular-linting
description	Quick-reference for linting the core Ignite UI for Angular library. Covers the combined lint command (`lint:lib`), ESLint for TypeScript and templates, and Stylelint for Sass/SCSS styles. Use when an agent needs to run the main linters, fix lint errors, or understand the primary lint configuration. Do NOT use for building — use igniteui-angular-build instead. Do NOT use for running tests — use igniteui-angular-testing instead.

Ignite UI for Angular — Linting

Quick-reference card for the core lint commands for the main library in this repository.

Prerequisites

• Run npm install at the repo root.

Commands

Command	What it runs
npm run lint:lib	ESLint + Stylelint (both — use this as the default)
npm run lint:styles	Stylelint only (Sass/SCSS files)
npm run lint	ng lint — ESLint only (TypeScript + templates)
ng lint --fix	Quick fix for tool identifiable fixes

lint:lib (recommended)

npm run lint:lib

This is the combined command and the one agents should run before considering work complete. It executes:

1. ng lint — ESLint on TypeScript source and Angular templates, using the config at projects/igniteui-angular/eslint.config.mjs.
2. npm run lint:styles — Stylelint on Sass files under projects/igniteui-angular/core/src/core/styles.

Lint Styles Only

npm run lint:styles

Runs stylelint "projects/igniteui-angular/core/src/core/styles". Use when you only changed SCSS/Sass and want a faster check.

Configuration Files

File	Purpose
eslint.config.mjs (repo root)	Root ESLint config
projects/igniteui-angular/eslint.config.mjs	Library-specific ESLint config (referenced in angular.json)
.stylelintrc.json (repo root)	Root Stylelint config used by npm run lint:styles

Agent Rules

• Always run npm run lint:lib before marking work complete — this is a requirement from AGENTS.md.
• Fix all lint errors before committing. Do not disable rules without justification.
• If a lint rule conflicts with the intended change, investigate whether the rule is correct before suppressing it.
