Konsta UI Design Guide

Build pixel-perfect iOS and Material Design apps with Konsta UI.

When to Use This Skill

• User wants native-looking UI without Ionic
• User asks about Konsta UI
• User wants iOS/Material Design components
• User is using React/Vue/Svelte
• User wants lightweight UI framework

What is Konsta UI?

Konsta UI provides:

• Pixel-perfect iOS and Material Design components
• Works with React, Vue, and Svelte
• Tailwind CSS integration
• ~40 mobile-optimized components
• Small bundle size (~30KB gzipped)

Getting Started

Installation

# React
npm install konsta

# Vue
npm install konsta

# Svelte
npm install konsta

# Required: Tailwind CSS
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p

Tailwind Configuration

// tailwind.config.js
const konstaConfig = require('konsta/config');

module.exports = konstaConfig({
  content: [
    './src/**/*.{js,ts,jsx,tsx,vue,svelte}',
  ],
  // Extend or override Konsta config
  theme: {
    extend: {},
  },
});

Setup (React)

// App.tsx
import { App, Page, Navbar, Block } from 'konsta/react';

export default function MyApp() {
  return (
    <App theme="ios"> {/* or theme="material" */}
      <Page>
        <Navbar title="My App" />
        <Block>
          <p>Hello Konsta UI!</p>
        </Block>
      </Page>
    </App>
  );
}

Setup (Vue)

<!-- App.vue -->
<template>
  <k-app theme="ios">
    <k-page>
      <k-navbar title="My App" />
      <k-block>
        <p>Hello Konsta UI!</p>
      </k-block>
    </k-page>
  </k-app>
</template>

<script setup>
import { kApp, kPage, kNavbar, kBlock } from 'konsta/vue';
</script>

  );
}

Theming

Theme Selection

import { App } from 'konsta/react';

// Auto-detect platform
<App theme="parent">

// Force iOS style
<App theme="ios">

// Force Material style
<App theme="material">

Dark Mode

import { App } from 'konsta/react';

// Auto dark mode (follows system)
<App dark>

// Explicit dark mode
<App dark={true}>

// Explicit light mode
<App dark={false}>

Custom Colors with Tailwind

// tailwind.config.js
const konstaConfig = require('konsta/config');

module.exports = konstaConfig({
  theme: {
    extend: {
      colors: {
        primary: {
          DEFAULT: '#6366f1',
          dark: '#4f46e5',
        },
      },
    },
  },
  // Override Konsta's primary color
  konstaConfig: {
    colors: {
      primary: '#6366f1',
    },
  },
});

Component-Level Styling

// Override individual component colors
<Button
  colors={{
    fillBg: 'bg-indigo-500',
    fillActiveBg: 'bg-indigo-600',
    fillText: 'text-white',
  }}
>
  Custom Button
</Button>

<Toggle
  colors={{
    bgChecked: 'bg-green-500',
  }}
/>

With Capacitor

Safe Area Handling

import { App, Page } from 'konsta/react';

function MyApp() {
  return (
    <App
      theme="ios"
      safeAreas  // Enable safe area handling
    >
      <Page>
        {/* Content respects safe areas */}
      </Page>
    </App>
  );
}

Capacitor Integration

import { App, Page, Button } from 'konsta/react';
import { Capacitor } from '@capacitor/core';

function MyApp() {
  const isNative = Capacitor.isNativePlatform();

  return (
    <App
      theme={Capacitor.getPlatform() === 'ios' ? 'ios' : 'material'}
      safeAreas={isNative}
    >
      <Page>
        <Button onClick={handleNativeAction}>
          Native Action
        </Button>
      </Page>
    </App>
  );
}

Comparison: Konsta vs Ionic

Feature	Konsta UI	Ionic
Bundle Size	~30KB	~200KB
Components	~40	~100+
Tailwind Integration	Native	Possible
Routing	External	Built-in
Framework Support	React, Vue, Svelte	React, Vue, Angular
Native Features	UI only	UI + Plugins

Choose Konsta when:

• You want Tailwind-first approach
• You need smaller bundle size
• You're using Svelte
• You want simpler setup

Choose Ionic when:

• You need comprehensive component library
• You want built-in routing
• You need more complex components
• You prefer all-in-one solution

Best Practices

Performance

// Lazy load heavy components
import { lazy, Suspense } from 'react';

const HeavyComponent = lazy(() => import('./HeavyComponent'));

function App() {
  return (
    <Suspense fallback={<div>Loading...</div>}>
      <HeavyComponent />
    </Suspense>
  );
}

Accessibility

// Konsta components are accessible by default
// Add labels for screen readers
<ListInput
  label="Email"
  type="email"
  placeholder="Enter email"
  // aria-label is automatically set from label
/>

// For icon-only buttons
<Button aria-label="Close menu">
  <Icon name="close" />
</Button>
