Vue integration

Roadie's core CSS layer works with any framework. It covers tokens, intents, emphasis, elevation, typography, and interaction utilities. This guide covers using Roadie in a Vue application where only the CSS foundation is needed.

The React component library (@oztix/roadie-components) is not compatible with Vue. Use the token and utility class system directly instead.

Installation

Install the core package only:

pnpm add @oztix/roadie-core

You also need Tailwind CSS v4 and PostCSS:

pnpm add tailwindcss @tailwindcss/postcss postcss

Setup

1. Configure PostCSS

Create or update postcss.config.js:

export default {
  plugins: {
    '@tailwindcss/postcss': {}
  }
}

2. Import Roadie CSS

In your main CSS entry point (e.g. src/assets/main.css):

@import '@oztix/roadie-core/css';

This single import includes Tailwind CSS v4, all design tokens, the reset, and every utility class.

3. Add font preconnect hints

Add these to your index.html <head>:

<link rel="preconnect" href="https://assets.oztix.com.au" crossorigin />
<link rel="preconnect" href="https://cdn.jsdelivr.net" crossorigin />

Usage

Layout

Use grid-first layout with Tailwind utility classes:

<div class="grid gap-6 p-6">
  <h1 class="text-display-ui-2 text-strong">Dashboard</h1>
  <div class="grid grid-cols-3 gap-4">
    <div class="emphasis-raised rounded-xl p-4">Card 1</div>
    <div class="emphasis-raised rounded-xl p-4">Card 2</div>
    <div class="emphasis-raised rounded-xl p-4">Card 3</div>

Buttons

Use the btn base class with a size (btn-sm, btn-md, btn-lg) plus intent, emphasis, and interaction utilities:

<!-- Standard buttons -->
<button class="btn btn-md intent-accent emphasis-strong is-interactive rounded-full">
  Primary action
</button>

<button class="btn btn-md intent-neutral emphasis-normal is-interactive rounded-full">

Available sizes: btn-xs (24px), btn-sm (32px), btn-md (40px), btn-lg (48px). Icon buttons use btn-icon-xs through btn-icon-lg.

Intent and emphasis

Set color context with intent-* classes. Children inherit the palette automatically via CSS cascade:

<div class="intent-accent">
  <button class="btn btn-md emphasis-strong is-interactive rounded-full">
    Inherits accent
  </button>
  <p class="text-subtle">This text is also accent-tinted.</p>
</div>

See the tokens overview for how intent and emphasis work together.

Typography

Use the display utility classes for headings and standard Tailwind for body text:

<h1 class="text-display-prose-1 text-strong">Page title</h1>
<h2 class="text-display-ui-3 text-strong">Section heading</h2>
<p class="text-subtle">Secondary body text.</p>
<p class="text-sm text-subtle">Small helper text.</p>

Semantic colors

Roadie replaces default Tailwind colors with semantic tokens:

<div class="bg-normal text-normal">Default surface</div>
<div class="bg-subtle text-subtle">Tinted surface</div>
<div class="bg-raised text-strong border-subtle border">Elevated card</div>
<div class="bg-sunken">Recessed area</div>

Elevation

Shadows are tinted by the current intent:

<div class="intent-accent shadow-lg rounded-xl p-6">
  Accent-tinted shadow
</div>

<div class="emphasis-raised rounded-xl p-4">
  Raised surface with rim-light and shadow

Form inputs

Style form inputs with the is-interactive-field utility for automatic state transitions (neutral at rest, accent on focus, danger when invalid):

<div class="grid gap-1.5">
  <label class="text-sm font-medium" for="email">Email</label>
  <input
    id="email"
    type="email"
    class="is-interactive-field rounded-lg border border-normal bg-normal px-3 py-2 text-normal"

For composite inputs (e.g. an input with an attached button), use is-interactive-field-group on the wrapper:

<div class="is-interactive-field-group flex rounded-lg border border-normal">
  <input
    type="text"
    class="flex-1 bg-transparent px-3 py-2 text-normal outline-none"
    placeholder="Search..."
  />

Interactive elements

Use is-interactive for buttons, cards, and clickable elements. It provides cursor, transitions, active scale, focus ring, and disabled state:

<button class="btn btn-md intent-brand emphasis-strong is-interactive rounded-full">
  Submit
</button>

<a href="/details" class="emphasis-subtle is-interactive rounded-xl p-4 no-underline">
  Clickable card

Shape

Follow the shape tier system for consistent border-radius:

Dark mode

Toggle dark mode by adding the dark class to the <html> element. All tokens adapt automatically, so you need no dark: variants.

For SSR-safe dark mode without flash, use the theme script from @oztix/roadie-core/theme:

import { getThemeScript } from '@oztix/roadie-core/theme'

Inject the script output into your index.html <head> as a blocking <script> tag. It reads localStorage and applies the dark class before first paint.

Dynamic accent color

To change the accent hue at runtime, use the color scale generator:

import { generateRadixScale } from '@oztix/roadie-core/colors'

const scale = generateRadixScale('#6366f1')
// Apply scale CSS variables to :root or a container element

What's not available

The following require the React component library and are not available in Vue:

• Pre-built components (Button, Select, Accordion, etc.)
• ThemeProvider React context (use the theme script + manual dark class toggling instead)
• useTheme() hook (manage theme state in your Vue app directly)

Everything else works identically. That includes tokens, intents, emphasis, elevation, typography, interactions, motion, and all Tailwind utilities.
