Theming

Theme Selection

tsx

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

tsx

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

javascript

// 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

tsx

// 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

tsx

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

tsx

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

tsx

// 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

tsx

// 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>
