Basic Workflow

Relevant source files

Purpose and Scope

This document describes the typical development workflows and patterns used when building user interfaces with @ui8kit/core. It covers common scenarios developers encounter when composing components, applying styling through the variant system, and building standard UI patterns like cards, forms, and layouts. For advanced scenarios where standard components are insufficient (e.g., creating custom form components), see Advanced Workflow. For general guidelines and performance recommendations, see Best Practices. Sources: .devin/wiki.json181-188 src/components/README.md1-259

Component Selection Workflow

The first step in any development workflow is selecting the appropriate component for your use case. The library follows a three-layer hierarchy where each layer serves specific purposes.

Decision matrix:

Scenario	Component Choice	Reason
Generic container with styling	`Box`	Flexible primitive with full variant support
Semantic HTML element (section, article, nav)	`Block`	Renders semantic tags with `component` prop
Grid layout	`Grid`	CSS Grid with responsive presets
Flexbox layout	`Flex` or `Stack`	Flex for general, Stack for vertical/horizontal
Interactive button	`Button`	Pre-styled with variants and states
Content card	`Card`	Compound component with Header/Content/Footer
Dashboard template	`DashLayout`	Complete layout with sidebar and header

Step-by-Step: Styling a Component

Step 1: Apply spacing variants

// Import component
import { Box } from '@ui8kit/core';

// Apply padding and margin
<Box p="lg" m="md" mx="auto">
  Content
</Box>

Available spacing values: none, xs, sm, md, lg, xl, 2xl, auto Step 2: Apply color variants

<Box p="lg" bg="card" c="foreground">
  Content with semantic colors
</Box>

Step 3: Apply visual effects

<Box p="lg" bg="card" rounded="xl" shadow="md" border="default">
  Styled container
</Box>

Step 4: Apply layout variants

<Box p="lg" w="full" h="screen" position="relative">
  Full-width layout
</Box>

Variant Props Reference

Category	Props	Values
Spacing	`p`, `px`, `py`, `pt`, `pb`, `pl`, `pr`	`none`, `xs`, `sm`, `md`, `lg`, `xl`, `2xl`
Spacing	`m`, `mx`, `my`, `mt`, `mb`, `ml`, `mr`	`none`, `xs`, `sm`, `md`, `lg`, `xl`, `2xl`, `auto`
Colors	`bg`, `c`, `borderColor`	Design system color tokens

Layout Pattern Workflows

Vertical Stacking with `Stack`

The most common layout pattern is vertical stacking of elements.

import { Stack, Title, Text, Button } from '@ui8kit/core';

<Stack gap="lg" align="center" p="md">
  <Title order={1}>Heading</Title>
  <Text>Description text</Text>
  <Button variant="primary">Action</Button>
</Stack>

Key Stack props:

gap: Space between children (xs, sm, md, lg, xl, 2xl)
align: Cross-axis alignment (start, center, end, stretch)
justify: Main-axis alignment (start, center, end, between, around)

Sources: src/components/README.md52-64

Horizontal Layout with `Group`

For horizontal arrangements, use Group.

import { Group, Button } from '@ui8kit/core';

<Group gap="md" align="center" justify="between">
  <Button variant="secondary">Cancel</Button>
  <Button variant="primary">Confirm</Button>
</Group>

Sources: src/components/README.md66-78

Grid Layout with `Grid`

For multi-column layouts, use Grid with responsive presets.

import { Grid, GridCol, Card } from '@ui8kit/core';

<Grid cols="1-2-3" gap="lg" p="md">
  <GridCol span={2}>
    <Card p="lg">Wide column</Card>
  </GridCol>
  <GridCol>
    <Card p="lg">Regular column</Card>
  </GridCol>
</Grid>

cols preset values:

"1-2-3": 1 column mobile, 2 tablet, 3 desktop
"2": 2 columns at all breakpoints
Custom: Use standard Grid props

Sources: src/components/README.md80-92 README.md90-103

Responsive Container

Use Container for centered, max-width layouts.

import { Container } from '@ui8kit/core';

<Container size="lg" px="md" centered>
  <Card p="lg">
    Centered content with responsive max-width
  </Card>
</Container>

Container sizes:

xs: 448px
sm: 640px
md: 768px
lg: 1024px
xl: 1280px

Sources: src/components/README.md39-50

UI Component Patterns

Working with Cards

Card is a compound component with semantic subcomponents.

Card (root container)

Card.Header

Card.Title

Card.Description

Card.Content

Card.Footer

data-class='card'

data-class='card-header'

data-class='card-title'

data-class='card-content'

data-class='card-footer'

Step-by-Step: Building a Card

import { Card, Title, Text, Button, Stack } from '@ui8kit/core';

<Card p="lg" rounded="xl" shadow="md" bg="card">
  <Card.Header>
    <Card.Title>Title</Card.Title>
    <Card.Description>Optional description</Card.Description>
  </Card.Header>
  
  <Card.Content>
    <Stack gap="md">
      <Text>Main content goes here</Text>
      <Text c="muted-foreground">Additional details</Text>
    </Stack>
  </Card.Content>
  
  <Card.Footer>
    <Button variant="primary">Action</Button>
  </Card.Footer>
</Card>

Sources: src/components/README.md96-117 README.md121-145

Working with Buttons

Button supports variants, sizes, loading states, and icon sections.

import { Button } from '@ui8kit/core';
import { Heart } from 'lucide-react';

// Basic button
<Button variant="primary" size="md">
  Click me
</Button>

// Button with icon
<Button 
  variant="default" 
  leftSection={<Heart size={16} />}
  rounded="md"
  shadow="sm"
>
  Favorite
</Button>

// Loading state
<Button variant="primary" loading={isLoading}>
  Submit
</Button>

Button variants:

default: Standard button
primary: Primary action
secondary: Secondary action
destructive: Dangerous actions
outline: Outlined style
ghost: Minimal style
link: Link-styled button

Sources: src/components/README.md119-133

Working with Typography

Use Title for headings and Text for body content.

import { Title, Text, Stack } from '@ui8kit/core';

<Stack gap="md">
  <Title order={1} size="3xl" weight="bold" c="primary">
    Main Heading
  </Title>
  
  <Title order={2} size="2xl" weight="semibold">
    Subheading
  </Title>
  
  <Text size="lg" c="muted-foreground" align="left">
    Body text with semantic styling
  </Text>
  
  <Text size="sm" weight="medium" truncate>
    Truncated text for overflow scenarios
  </Text>
</Stack>

Title order mapping:

order={1}: <h1> tag
order={2}: <h2> tag
order={3}: <h3> tag
(continues to order={6})

Sources: src/components/README.md150-177

Working with Badges

Use Badge for status indicators and labels.

import { Badge, Group } from '@ui8kit/core';
import { CheckCircle } from 'lucide-react';

<Group gap="sm">
  <Badge variant="success" size="sm" rounded="full">
    Active
  </Badge>
  
  <Badge 
    variant="default" 
    dot
    rightSection={<CheckCircle size={14} />}
  >
    Verified
  </Badge>
</Group>

Badge variants:

default: Standard badge
success: Green/positive
warning: Yellow/caution
error: Red/negative
outline: Outlined style

Sources: src/components/README.md135-148

Semantic HTML Workflow

Use Block with the component prop to render semantic HTML5 elements.

import { Block, Title, Text } from '@ui8kit/core';

<Block component="section" py="xl" bg="background">
  <Block component="article" p="lg" rounded="lg">
    <Title order={2}>Article Title</Title>
    <Text>Article content</Text>
  </Block>
</Block>

<Block component="nav" p="md" bg="card">
  <Block component="ul">
    <Block component="li">Nav item</Block>
  </Block>
</Block>

<Block component="header" py="md" border="bottom">
  <Title>Page Header</Title>
</Block>

<Block component="footer" py="lg" bg="muted">
  <Text size="sm">Footer content</Text>
</Block>

Common semantic elements:

section: Thematic grouping
article: Self-contained content
nav: Navigation links
header: Introductory content
footer: Footer content
aside: Sidebar content
main: Main content area

Sources: src/components/README.md23-37 README.md14

      <Card.Content>
        <Stack gap="md">
          <Box>
            <Text weight="medium" mb="xs">
              Email
            </Text>
            <Box 
              component="input"
              type="email"
              p="sm"
              rounded="md"
              border="default"
              w="full"
            />
          </Box>
          
          <Box>

Data Attribute Targeting

All UI components include data-class attributes for semantic targeting in CSS and tests.

<Card data-class="card">
  <Card.Header data-class="card-header">
    <Card.Title data-class="card-title">Title</Card.Title>
  </Card.Header>
  <Card.Content data-class="card-content">
    Content
  </Card.Content>
</Card>

CSS targeting example:

[data-class="card"] {
  /* Custom card styles */
}

[data-class="card-header"] {
  /* Custom header styles */
}

Test selector example:

// In tests
const card = screen.getByTestId('card');
const header = within(card).getByTestId('card-header');
