ng-blatui

Accessible Angular UI library — a faithful port of BlatUI's visual system to Angular. Built on the official Angular headless stack (Angular Aria + CDK), styled with Tailwind CSS v4 + oklch design tokens.

157 components · 16 blocks · 70 charts · 35 page templates — all standalone, signal-based, zoneless and SSR-safe.

Highlights

• Angular 21 & 22 — standalone components, signals (input()/model()/output()), zoneless change detection, OnPush by default.
• SSR-ready — every component renders correctly under server-side rendering (the docs site prerenders 280+ static routes).
• Accessible — behavior built on @angular/aria + @angular/cdk; passes AXE / WCAG AA.
• Forms-native — every form control implements ControlValueAccessor, so the same component works with Reactive, Template-driven and Signal forms.
• Themeable — Tailwind v4 utilities + CSS variables (oklch tokens); light/dark out of the box.
• AI-ready — ships an MCP server, an llms.txt index and a machine-readable registry (see below).

Installation

npm i ng-blatui

Peer dependencies (Angular 21 or 22): @angular/core, @angular/common, @angular/forms, @angular/cdk, @angular/aria.

Tailwind CSS setup

Styling is Tailwind CSS v4. In your app's global stylesheet (e.g. src/styles.css) add three lines:

@import 'tailwindcss';
@import 'ng-blatui/foundations/blatui.css'; /* design tokens + dark theme */
@source '../node_modules/ng-blatui'; /* ← generate the utilities the lib's classes use */

The @source line is the easy one to miss: without it Tailwind never scans ng-blatui's compiled templates, so the components render unstyled. Point it at wherever ng-blatui lives relative to the stylesheet (adjust the ../ depth). Dark mode is a dark class on a parent (<html class="dark">); override any oklch token in :root / .dark to re-theme. Full guide: https://ngblatui.remix-it.com/docs/installation.

Icons

ng-blatui ships no icon set — wire your own (e.g. @ng-icons) with provideIcons(...) and register each icon you use. Components that take an icon accept an SVG path d string, so any icon source works.

Usage

Import the component class from the ng-blatui barrel and add it to a standalone component's imports[] — no NgModule. Selectors are prefixed bui.

import { Component } from '@angular/core';
import { BuiButton, BuiBadge, BuiInput } from 'ng-blatui';

@Component({
  selector: 'app-demo',
  imports: [BuiButton, BuiBadge, BuiInput],
  template: `
    <label>
      Email
      <input buiInput type="email" placeholder="you@example.com" />
    </label>
    <button buiButton>Save <span buiBadge tone="success">New</span></button>
  `,
})
export class Demo {}

• Element selectors: <bui-avatar>, <bui-rating>, …
• Attribute/directive selectors: <button buiButton>, <input buiInput>, <span buiBadge tone="success">, …
• Signals: bind [checked] / (checkedChange) etc.; works under zoneless CD and SSR with no extra setup.
• Forms: formControlName, [(ngModel)] or [formControl] all work — every control is a ControlValueAccessor.

Form fields: two levels

• Batteries-included components wire label + hint + error + ARIA for you: BuiInputField, BuiMoneyInput (localized currency; symbol="DH" overrides the ISO code), BuiDateRangePicker (start→end with presets), plus BuiSelect, BuiCombobox, BuiAutocomplete, BuiPhoneInput.
• Composition primitives for custom layouts: buiField + buiFieldLabel / buiFieldDescription / buiFieldError wrap a bare buiInput / .blat-* control and manage the a11y relationships.

Reach for a bare control (buiInput) only when you also add the buiField scaffolding yourself. Other easy-to-miss building blocks: buiEmpty (empty states), bui-stat (stat cards), buiFieldSet / buiFieldLegend (grouped fields).

Theming

Styling is Tailwind v4 + CSS variables. Override the oklch design tokens (--background, --foreground, --primary, --border, --muted, --radius, …) to restyle everything globally; toggle a dark class for dark mode. See https://ngblatui.remix-it.com/docs/theming.

Localization

Two providers cover the whole library, both set once in your app config:

import { provideBuiLabels, provideBuiLocale } from 'ng-blatui';

providers: [
  provideBuiLocale('fr-BE'), // dates, times, numbers, week start, weekend, week numbering
  provideBuiLabels({ fileUploadRemove: 'Supprimer le fichier' }), // built-in strings
];

Set neither and everything formats as en-US — that is Angular's own LOCALE_ID default, and the usual reason pickers stay American in an app that is not. Resolution runs most-specific first: a component's [locale] input → provideBuiLocale() → the app's LOCALE_ID → en-US. You never need registerLocaleData() here; ng-blatui formats through Intl.

Both providers also take a signal, or a factory run in an injection context — which is what keeps them open to any translation library (Transloco, ngx-translate, a signal store of your own) without ng-blatui depending on one, or knowing any translation format. Full guide, with a Transloco example: https://ngblatui.remix-it.com/docs/localization.

Templates are full, production-style pages (dashboard, pricing, auth, store, CRM, blog, docs, e-commerce product, plus 20 art-directed landing pages) — faithful 1:1 reproductions of the BlatUI originals.

Using with AI agents

ng-blatui is built to be consumed by AI coding assistants so they discover and use the catalog correctly instead of guessing — via three layers:

Layer	What	Where
MCP server	Tools to list/search the catalog and fetch full docs + code	npx ng-blatui-mcp
llms.txt	The llms.txt standard index	https://ngblatui.remix-it.com/llms.txt
registry.json	Machine-readable catalog	https://ngblatui.remix-it.com/registry.json

Quick start (works in Claude, Cursor, Windsurf, Cline, Zed, VS Code…):

claude mcp add ng-blatui -- npx -y ng-blatui-mcp
# or add to any MCP client:
# { "mcpServers": { "ng-blatui": { "command": "npx", "args": ["-y", "ng-blatui-mcp"] } } }

The MCP server exposes list_components (optional category), list_blocks, list_charts, list_templates, search({ query }) and get_docs({ name }). Full guide with per-client config and copy-paste editor rules: USING-WITH-AI.md.

Development

This is an Angular workspace with two projects: the library (projects/ng-blatui) and the docs/demo app (projects/demo).

git clone https://github.com/anousss007/ng-blatui.git
cd ng-blatui
npm install
npm start          # serve the docs/demo app at http://localhost:4200

Scripts

Command	What it does
npm start	Serve the demo app (ng serve demo)
npm run build:lib	Build the publishable library (ng build ng-blatui)
npm run build	Build the demo site
npm test	Unit tests (Vitest)
npm run lint	ESLint (type-aware, strict) + template a11y
npm run format	Prettier (with Tailwind class sorting)
npm run build:registry	Regenerate registry.json + llms.txt from the catalog
npm run capture:previews	Capture template preview images (Playwright)
npm run deploy:site	Build + deploy the docs site to the VPS

Conventions

Angular v22, zoneless, standalone (defaults — never set explicitly). Signals everywhere; native control flow (@if/@for/@switch); no *ngIf/ngClass. Library selector prefix bui, demo prefix app. See AGENTS.md and CONTRIBUTING.md for the full ruleset.

Releasing

• Library (ng-blatui) — the Release GitHub Actions workflow (manual dispatch) runs semantic-release: it analyzes Conventional Commits, bumps the version, tags, creates a GitHub release and publishes to npm with provenance.
• MCP server (ng-blatui-mcp) — bump mcp/package.json, then run the Release MCP workflow (manual dispatch) to publish it.
