igniteui-angular-linting

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) ```bash 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 ```bash 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](../../../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. ## Related Skills - [`igniteui-angular-build`](../igniteui-angular-build/SKILL.md) — Building the library - [`igniteui-angular-testing`](../igniteui-angular-testing/SKILL.md) — Running tests

igniteui-angular-testing

Quick-reference for running Ignite UI for Angular test suites. Covers the full library run (`test:lib`) on Vitest browser mode through the Angular unit-test builder, running a subset with `--include`/`--filter`, watch mode, extras/elements suites, and auxiliary suites (schematics, styles, i18n). WHEN TO USE: running, selecting, or understanding the test infrastructure. WHEN NOT TO USE: building (use igniteui-angular-build) or linting (use igniteui-angular-linting).

igniteui-angular-components

Covers all non-grid Ignite UI for Angular UI components: application scaffolding and setup, form controls (inputs, combos, selects, date/time pickers, calendar, checkbox, radio, switch, slider), layout containers (tabs, stepper, accordion, splitter, navigation drawer), data-display components (list, tree, card, chips, carousel, paginator, progress indicators, chat), feedback overlays (dialog, snackbar, toast, banner), directives (button, icon button, button group, ripple, tooltip, drag-and-drop), Dock Manager, Layout Manager, Tile Manager, and Charts. WHEN TO USE: users ask about any Ignite UI Angular component that is NOT a data grid, such as forms, dropdowns, pickers, dialogs, navigation, lists, trees, cards, charts, or initial project setup. WHEN NOT TO USE: data grids, tables, or tabular data (use igniteui-angular-grids); theming or styling (use igniteui-angular-theming).

Provides guidance on all Ignite UI for Angular data grid types (Flat Grid, Tree Grid, Hierarchical Grid, Grid Lite, Pivot Grid) including setup, column configuration, sorting, filtering, selection, editing, grouping, summaries, toolbar, export, paging, remote data, and state persistence. WHEN TO USE: users ask about grids, tables, data grids, tabular data display, cell editing, batch editing, row selection, column pinning, column hiding, grouping rows, pivot tables, tree-structured data, hierarchical data, master-detail views, or exporting grid data. WHEN NOT TO USE: non-grid UI components such as forms, dialogs, navigation, or charts (use igniteui-angular-components); theming or styling (use igniteui-angular-theming).
