Webpack/Vite/Parcel: The library works out-of-the-box with modern bundlers.

CSS Framework Integration: You can use the components with any CSS framework. The included CSS provides Material Design styling, but you can override it with your own styles.

TypeScript: Full TypeScript support with comprehensive type definitions included.

See the live documentation for examples and component APIs.

> Note: The date range picker is now fully implemented with comprehensive validation and formatting support.

Build instructions

This repository consists of two packages, combined using lerna: the lib package that is published to npm, as well as an example project which uses this library to display the Mithril components that it contains.

To install the dependencies, you can use npm i, or, alternatively, use pnpm m i (assuming you have installed pnpm as alternative package manager using npm i -g pnpm) to perform a multi-repository install. Next, build everything using npm start and visit the documentation page on http://localhost:1234 in case port 1234 is not occupied already.

🎨 Styling & CSS

$3

The library includes carefully crafted CSS that provides Material Design styling without external dependencies. You can import the ready-to-use CSS:

`typescript
import 'mithril-materialized/index.css';
`

Important: The CSS styling is completely independent of the original materialize-css. This means:

- ✅ No conflicting styles from materialize-css
- ✅ Smaller CSS bundle size
- ✅ Custom optimizations for better performance
- ✅ No external font dependencies

$3

Tree-shakable CSS modules for optimal bundle sizes! Import only the CSS you need:

`typescript
// Option 1: Import everything (64KB total)
import 'mithril-materialized/index.css';

// Option 2: Import only what you need (modular approach)
import 'mithril-materialized/core.css'; // Essential styles (18KB)
import 'mithril-materialized/forms.css'; // Form components only
import 'mithril-materialized/components.css'; // Interactive components

// Option 3: Advanced components only when needed
import 'mithril-materialized/pickers.css'; // Date/Time pickers
import 'mithril-materialized/advanced.css'; // Carousel, sidenav, etc.
import 'mithril-materialized/utilities.css'; // Badges, icons, cards
`

CSS Modules Available:

- core.css (18KB) - Essential foundation (normalize, grid, typography, variables)
- components.css - Interactive components (buttons, dropdowns, modals, tabs)
- forms.css - All form components (inputs, selects, switches, file upload)
- pickers.css - Date and time picker components
- advanced.css - Specialized components (carousel, sidenav, navbar, preloader)
- utilities.css - Visual utilities (badges, cards, icons, toast, chips)

Bundle Size Optimization:

- Full bundle: 64KB gzipped (44KB JS + 20KB CSS)
- Modular approach can reduce CSS by 30-50%
- Use only core.css + specific modules for your use case

$3

Built-in dark theme support with CSS custom properties:

`typescript
import { ThemeManager, ThemeSwitcher } from 'mithril-materialized';

// Programmatic theme control
ThemeManager.setTheme('dark'); // 'light' | 'dark' | 'auto'
ThemeManager.toggle(); // Toggle between light/dark
ThemeManager.getTheme(); // Get current theme

// UI Components
m(ThemeSwitcher, {
onThemeChange: (theme) => console.log('Theme:', theme)
});

m(ThemeToggle); // Simple toggle button
`

CSS Custom Properties: All colors use CSS variables for runtime theme switching:

`css
:root {
--mm-primary-color: #26a69a;
--mm-background-color: #ffffff;
--mm-text-primary: rgba(0, 0, 0, 0.87);
}

[data-theme="dark"] {
--mm-primary-color: #80cbc4;
--mm-background-color: #121212;
--mm-text-primary: rgba(255, 255, 255, 0.87);
}
`

$3

For advanced customization, you can use the SASS source files directly:

`css
// Import all SASS components
@import 'mithril-materialized/sass/materialize.scss';

// Or import individual components
@import 'mithril-materialized/sass/components/buttons';
@import 'mithril-materialized/sass/components/forms';
@import 'mithril-materialized/sass/components/grid';
`

SASS Variables: You can customize colors, spacing, and other design tokens by overriding SASS variables before importing:

`css
// Customize Material Design variables
$primary-color: #2196F3;
$secondary-color: #FF9800;

// Then import the library
@import 'mithril-materialized/sass/materialize.scss';
`

The library includes these additional styles for enhanced functionality:

`css
/ For the switch /
.clear,
.clear-10,
.clear-15 {
clear: both;
/ overflow: hidden; Precaution pour IE 7 /
}
.clear-10 {

}
.clear-15 {
margin-bottom: 15px;
}

span.mandatory {
margin-left: 5px;
color: red;
}

label+.switch {
margin-top: 1rem;
}

}
