@latty-ds/web

Web Components for the Latty Design System — framework-agnostic UI components built with Lit and driven by design tokens.

Installation

pnpm add @latty-ds/tokens @latty-ds/web

Setup

Import the CSS tokens once in your app entry point, then import the component library:

/* your global stylesheet */
@import '@latty-ds/tokens/tokens.css';
@import '@latty-ds/tokens/semantic.css';

import '@latty-ds/web';

Or import individual components to keep bundles small:

import '@latty-ds/web/dist/components/button';
import '@latty-ds/web/dist/components/textfield';

Components

Buttons, inputs, overlays, navigation, data display, and more — all prefixed lt-*. See the full component reference for props, events, and live examples.

Usage

Components work in any HTML environment — no framework required.

<lt-button variant="primary" size="md">Save changes</lt-button>

<lt-textfield label="Email" type="email" required></lt-textfield>

<lt-badge variant="success">Active</lt-badge>

<lt-spinner size="md" variant="primary"></lt-spinner>

Common props

Most components share these props:

• variant — primary | secondary | neutral | success | warning | error | info
• size — sm | md | lg
• disabled — boolean

All props reflect to HTML attributes, so server-rendered markup works out of the box.

Icons

Pass an icon name to components that support them:

<lt-button icon="save">Save</lt-button>
<lt-button icon-end="arrow-right">Next</lt-button>
<lt-textfield icon-start="search" placeholder="Search…"></lt-textfield>

See @latty-ds/icons for the full icon reference.

CSS customization

Components expose CSS parts for external styling:

lt-button::part(button) {
  border-radius: 999px;
}

All visual properties are driven by --lt-* CSS custom properties. Override tokens globally or per-component:

:root {
  --lt-interactive-primary-bg: hotpink;
}

lt-button {
  --lt-interactive-primary-bg: hotpink;
}

TypeScript

Full type definitions are included. Import types directly:

import type { Button } from '@latty-ds/web';

The custom-elements.json manifest (at the package root) is compatible with VS Code's custom data format for HTML IntelliSense.
