Quick Start

Get up and running with Entangle UI in under five minutes.

Basic Setup

Import the dark theme CSS to register all --etui-* CSS custom properties on :root. No wrapper component is needed for the default look:

import 'entangle-ui/theme';
import { Button } from 'entangle-ui';

function App() {
  return <Button variant="filled">Save</Button>;
}

The default dark theme is applied automatically — no extra configuration required.

With Custom Overrides

Override tokens with plain CSS on any selector:

.my-theme {
  --etui-color-accent-primary: #2aa1ff;
  --etui-color-bg-primary: #0d1117;
}

Or use VanillaThemeProvider for scoped overrides:

import 'entangle-ui/theme';
import { VanillaThemeProvider } from 'entangle-ui';

function App() {
  return (
    <VanillaThemeProvider className="my-theme">
      <YourApp />
    </VanillaThemeProvider>
  );
}

Your First Component

import { Button, Stack, Text } from 'entangle-ui';

function Welcome() {
  return (
    <Stack direction="column" spacing={3} align="center">
      <Text variant="heading">Welcome to Entangle UI</Text>
      <Stack direction="row" spacing={2}>
        <Button variant="default">Cancel</Button>
        <Button variant="filled">Get Started</Button>
      </Stack>
    </Stack>
  );
}

Common Patterns

Sizing

Most components support a consistent size prop:

<Button size="sm">Small</Button>
<Button size="md">Medium</Button>   {/* default */}
<Button size="lg">Large</Button>

<Input size="sm" placeholder="Small input" />
<Slider size="md" min={0} max={100} value={50} />

Size	Typical Height
sm	20px
md	24px
lg	32px

Responsive Layout

Stack and Flex support responsive direction changes at four breakpoints:

<Stack direction="column" md="row" spacing={2}>
  <Sidebar />
  <Content />
</Stack>

Breakpoint	Width
sm	576px
md	768px
lg	992px
xl	1200px

Form Inputs

Combine Input with form components for labeled fields with validation:

<Input
  label="Project Name"
  placeholder="My Project"
  helperText="Choose a unique name"
  error={!!nameError}
  errorMessage={nameError}
  required
  value={name}
  onChange={setName}
/>

Application Shell

Build a complete editor layout:

import {
  AppShell,
  MenuBar,
  Toolbar,
  StatusBar,
  useAppShell,
} from 'entangle-ui';

function Editor() {
  const appShell = useAppShell();

  return (
    <AppShell>
      <AppShell.MenuBar>
        <MenuBar>{/* menu items */}</MenuBar>
      </AppShell.MenuBar>
      <AppShell.Toolbar>
        <Toolbar>
          <Toolbar.Button icon={<SaveIcon />}>Save</Toolbar.Button>
          <Toolbar.Separator />
          <Toolbar.Toggle icon={<GridIcon />}>Grid</Toolbar.Toggle>
        </Toolbar>
      </AppShell.Toolbar>
      <AppShell.Dock>{/* panels */}</AppShell.Dock>
      <AppShell.StatusBar>
        <StatusBar>
          <StatusBar.Section>Ready</StatusBar.Section>
        </StatusBar>
      </AppShell.StatusBar>
    </AppShell>
  );
}
