Malachite UI is a component library inspired by Tailwind's Headless UI. Built completely from scratch in TypeScript for Svelte, designed to work nicely with CSS Frameworks like Tailwind CSS or WindiCSS.
npm install malachite-ui -D
pnpm add malachite-ui -D
-
Functional: Sit down and relax. Most components will handle all logic and state on their own.
-
Headless: Build beautiful and unique components, we don't stand in your way.
-
Reactive: Worry no more, components will react instantly to any prop changes.
-
Svelte Friendly: All components are handled individually by a single action, meaning you can extract and use them on vanilla DOM elements, this way you have absolute control. You can use Svelte directives like transitions!
<Disclosure let:button let:panel let:close> <button use:button>Toggle</button> <div slot="panel" use:panel transition:fade> <p>Lorem ipsum dolor sit amet consectetur, adipisicing elit.</p> <button on:click="{close}">Close Me</button> </div> </Disclosure>
-
Maximum Styling: No more convoluted classNames. Most components support what I call Object ClassNames and Switch ClassNames (Don't know if other libraries have this but it's cool nonetheless):
<PopoverButton class="{{ base: 'button', open: 'button--open' }}"> Toggle </PopoverButton> <Tab class="{{ base:'tab', selected: { on: 'tab--selected', off: 'tab-unselected' } }}"> The Tab </Tab> <!-- we support functional classNames too! --> <PopoverButton class={({ isOpen }) => "button `${isOpen ? 'button--open' : ''}`"}> Toggle </PopoverButton> <!-- or you can use the Svelte way --> <Popover let:button let:isOpen> <button class="button" button--open="{isOpen}" use:button>Toggle</button> </Popover>
You can import and use the useClassNameResolver hook and apply it to normal HTML elements if you are using actions:
<script lang="ts"> import { useClassNameResolver } from 'malachite-ui/hooks'; let isDarkTheme = false; const resolve = useClassNameResolver<'CHECKED' | 'DISABLED'>({ base: 'switch', disabled: 'switch--disabled', checked: { on: 'switch--checked', off: 'switch--unchecked' } }); </script> <Switch as="fragment" bind:checked="{isDarkTheme}" let:switcher let:isChecked let:isDisabled> <button class="{resolve({ isChecked, isDisabled })}" use:switcher on:click="{toggleDarkTheme}"> <span class="sr-only"> Toggle Dark Theme </span> </button> </Switch>
This might seem like overkill if you are using simple and short classNames, however if you are using utility CSS frameworks like Tailwind CSS and WindiCSS you will very likely have a substantial amount of classNames, in that case this really comes in handy for better readability.
