# UX Implementation Guide
> **Purpose:** Comprehensive guide for UX implementation across ByteLyst products using common platform UI packages, design tokens, and Cipher design system integration.
> **Target Audience:** Product teams implementing UX improvements and testing infrastructure.
> **Product:** NoteLett - Agentic note-taking workspace for notes, tasks, relationships, and workspaces
---
## Overview
This guide documents the complete UX implementation approach for NoteLett, replicating the patterns established in the trading dashboard. The approach covers:
- **Common Platform UI Integration** - Leveraging `@bytelyst/ui` shared primitives
- **Design Token Usage** - Using `@bytelyst/design-tokens` for consistent styling
- **Component Normalization** - Replacing one-off components with shared primitives
- **Accessibility Improvements** - Keyboard navigation, ARIA labels, focus management
- **Responsive Design** - Viewport matrix testing, shell breakpoints
- **Testing Infrastructure** - Playwright E2E tests, Storybook, AI-friendly reports
- **Cipher Design System** - Visual hierarchy, spacing, typography principles
---
## Part 1: Common Platform UI Integration
### Local Package Resolution
**Critical:** Use local common platform packages by default, not Gitea registry.
**File:** `.pnpmfile.cjs`
```javascript
// .pnpmfile.cjs
// Default to local common platform packages
function readPackage(pkg, context) {
if (!context.workspace) return pkg;
// Default to common-plat (local packages)
const packageSource = process.env.BYTELYST_PACKAGE_SOURCE || 'common-plat';
if (packageSource === 'common-plat') {
// Resolve @bytelyst/* packages from local common platform
if (pkg.name.startsWith('@bytelyst/')) {
pkg.dependencies = pkg.dependencies || {};
pkg.dependencies[pkg.name] = 'workspace:*';
}
}
return pkg;
}
module.exports = {
name: 'bytelyst-package-source',
hooks: {
readPackage,
},
};
```
**File:** `.npmrc`
```ini
# Remove repo-level GITEA_NPM_TOKEN interpolation
# Gitea registry auth should live in user-level ~/.npmrc or CI secrets
# Only when BYTELYST_PACKAGE_SOURCE=gitea is explicitly used
```
### Environment Variables
```bash
# Default: Use local common platform packages
BYTELYST_PACKAGE_SOURCE=common-plat
# Optional: Use Gitea registry (requires auth)
BYTELYST_PACKAGE_SOURCE=gitea
# GITEA_NPM_TOKEN should be in ~/.npmrc or CI secrets
```
### Verification Commands
```bash
# Verify local package resolution
pnpm install @bytelyst/ui @bytelyst/design-tokens
# Verify packages resolve from local common platform
pnpm list @bytelyst/ui
# Should show: @bytelyst/ui -> link:../learning_ai_common_plat/packages/ui
```
### Product Adapter Pattern
Create a product adapter to normalize imports and extend shared primitives with product-specific variants:
**File:** `web/src/components/ui/Primitives.tsx`
```typescript
import * as React from 'react';
import {
Badge as CommonBadge,
Button as CommonButton,
Field,
FieldContent,
FieldDescription,
FieldError,
FieldGroup,
FieldLabel,
FieldTitle,
Input as CommonInput,
Select as CommonSelect,
Textarea as CommonTextarea,
type BadgeProps as CommonBadgeProps,
type ButtonProps as CommonButtonProps,
type InputProps as CommonInputProps,
type SelectProps as CommonSelectProps,
type TextareaProps as CommonTextareaProps,
} from '@bytelyst/ui';
// Re-export all shared primitives
export {
ActionMenu,
AlertBanner,
DataList,
DataTable,
Drawer,
EmptyState,
EntityCard,
FieldGrid,
FilterBar,
FormSection,
MetricCard,
Modal,
PageHeader,
Panel,
Skeleton,
Timeline,
Toolbar,
// ... all other @bytelyst/ui components
} from '@bytelyst/ui';
// Define product-specific variants for NoteLett
type ProductButtonVariant = NonNullable<CommonButtonProps['variant']> | 'link';
type ProductButtonSize = NonNullable<CommonButtonProps['size']> | 'icon';
type ProductFieldVariant = 'surface' | 'muted';
type ProductFieldSize = 'sm' | 'md';
type ProductBadgeVariant = NonNullable<CommonBadgeProps['variant']> | 'danger';
type ProductStatusTone = 'success' | 'warning' | 'error' | 'info' | 'neutral';
// Extend interfaces with product-specific props
export interface ButtonProps extends Omit<CommonButtonProps, 'variant' | 'size'> {
variant?: ProductButtonVariant;
size?: ProductButtonSize;
}
export interface IconButtonProps extends Omit<ButtonProps, 'children'> {
icon: React.ReactNode;
label: string;
}
export interface InputProps extends CommonInputProps {
controlSize?: ProductFieldSize;
variant?: ProductFieldVariant;
}
// NoteLett-specific status mapping for badges
export type NotelettStatus =
| 'active' | 'archived' | 'pinned' | 'shared' | 'private'
| 'draft' | 'published' | 'linked' | 'orphaned' | 'synced'
| 'syncing' | 'error' | 'success' | 'warning' | 'info' | 'neutral';
const notelettStatusTone: Record<NotelettStatus, ProductStatusTone> = {
active: 'success',
archived: 'neutral',
pinned: 'info',
shared: 'success',
private: 'neutral',
draft: 'warning',
published: 'success',
linked: 'info',
orphaned: 'warning',
synced: 'success',
syncing: 'info',
error: 'error',
success: 'success',
warning: 'warning',
info: 'info',
neutral: 'neutral',
};
// Helper function to map note status to tone
export function statusToneFor(status: NotelettStatus | string | null | undefined): ProductStatusTone {
if (!status) return 'neutral';
const normalized = status.trim().toLowerCase().replace(/[\s_]+/g, '-') as NotelettStatus;
return notelettStatusTone[normalized] ?? 'neutral';
}
// Product-specific component implementations
export const Button = React.forwardRef<HTMLButtonElement, ButtonProps>(
({ variant = 'primary', size = 'md', className, ...props }, ref) => (
<CommonButton
ref={ref}
variant={variant === 'link' ? 'ghost' : variant}
size={size === 'icon' ? 'sm' : size}
className={cn('notelett-button', className)}
{...props}
/>
),
);
export const IconButton = React.forwardRef<HTMLButtonElement, IconButtonProps>(
({ icon, label, variant = 'ghost', size = 'icon', className, ...props }, ref) => (
<Button
ref={ref}
type="button"
aria-label={label}
variant={variant}
size={size}
className={cn('shrink-0', className)}
{...props}
>
{icon}
</Button>
),
);
export const Input = React.forwardRef<HTMLInputElement, InputProps>(
({ controlSize = 'md', variant = 'surface', className, ...props }, ref) => (
<CommonInput
ref={ref}
className={cn(
controlSize === 'sm' ? 'min-h-9 px-3 py-2 text-xs' : 'min-h-11 px-3.5 py-2.5 text-sm',
variant === 'surface' ? 'bg-[var(--nl-input)]' : 'bg-[var(--nl-surface-muted)]',
className,
)}
{...props}
/>
),
);
export function NotelettStatusBadge({
status,
children,
}: {
status: NotelettStatus | string | null | undefined;
children?: React.ReactNode;
}) {
return (
<Badge variant={statusToneFor(status)} dot>
{children ?? status ?? 'Unknown'}
</Badge>
);
}
```
**Benefits of Product Adapter Pattern:**
- Centralized import point for all UI components
- Product-specific variants without modifying common platform
- Consistent styling across the application
- Easy to migrate to new common platform versions
- Type-safe extensions with TypeScript
---
## Part 2: Design Token Usage
### CSS Variable Integration
Use design tokens from `@bytelyst/design-tokens` via CSS custom properties with NoteLett-specific prefixes:
```css
/* Surface colors */
background: var(--nl-surface-card);
background: var(--nl-surface-muted);
background: var(--nl-surface-overlay);
/* Text colors */
color: var(--nl-text-primary);
color: var(--nl-text-secondary);
color: var(--nl-text-muted);
/* Border colors */
border-color: var(--nl-border);
border-color: var(--nl-border-muted);
/* Input styling */
background: var(--nl-input);
color: var(--nl-text-primary);
border-color: var(--nl-border);
/* Focus states */
border-color: var(--nl-focus-ring);
box-shadow: 0 0 0 2px var(--nl-focus-ring-muted);
/* Semantic colors */
color: var(--nl-accent);
background: var(--nl-success);
background: var(--nl-warning);
background: var(--nl-error);
/* Spacing */
padding: var(--nl-spacing-sm);
padding: var(--nl-spacing-md);
padding: var(--nl-spacing-lg);
padding: var(--nl-spacing-xl);
/* Border radius */
border-radius: var(--nl-radius-control);
border-radius: var(--nl-radius-md);
border-radius: var(--nl-radius-lg);
/* Typography */
font-size: var(--nl-text-sm);
font-size: var(--nl-text-base);
font-size: var(--nl-text-lg);
font-weight: var(--nl-font-medium);
font-weight: var(--nl-font-semibold);
```
### Component Token Patterns
**Example: Badge Component for NoteLett**
```typescript
// Using design tokens for badge styling
const badgeStyles = {
success: {
background: 'var(--nl-success-light)',
color: 'var(--nl-success-dark)',
borderColor: 'var(--nl-success)',
},
warning: {
background: 'var(--nl-warning-light)',
color: 'var(--nl-warning-dark)',
borderColor: 'var(--nl-warning)',
},
error: {
background: 'var(--nl-error-light)',
color: 'var(--nl-error-dark)',
borderColor: 'var(--nl-error)',
},
};
```
---
## Part 3: Component Normalization
### Badge Normalization
**Before:** One-off CSS classes for different badge styles
```css
/* Old approach - one-off classes */
.note-chip {
background: #f0f0f0;
padding: 4px 8px;
border-radius: 4px;
font-size: 12px;
}
.workspace-tag {
background: #e0e0e0;
padding: 6px 12px;
border-radius: 6px;
}
.status-pill {
background: #d0d0d0;
padding: 5px 10px;
border-radius: 20px;
}
```
**After:** Shared Badge component from product adapter
```typescript
import { Badge, NotelettStatusBadge } from '../components/ui/Primitives';
// Replace .note-chip with Badge
<Badge variant="success">Active</Badge>
// Replace .workspace-tag with Badge
<Badge variant="info">Personal</Badge>
// Replace .status-pill with NotelettStatusBadge
<NotelettStatusBadge status="pinned" />
```
### Alert Banner Unification
**Before:** Different alert implementations across components
```typescript
// NotesList.tsx - custom alert
<div className="alert-banner" style={{ background: '#fff3cd' }}>
<span>⚠️</span>
<span>Warning message</span>
</div>
// WorkspacesTab.tsx - different alert
<div className="warning-box" style={{ border: '1px solid #ffc107' }}>
<div className="warning-icon">!</div>
<div className="warning-text">Warning text</div>
</div>
```
**After:** Shared AlertBanner component
```typescript
import { AlertBanner } from '../components/ui/Primitives';
// Both components now use shared AlertBanner
<AlertBanner tone="warning" title="Warning">
Warning message
</AlertBanner>
<AlertBanner tone="error" title="Error">
Error message
</AlertBanner>
```
### Table Controls Standardization
**Before:** Custom table controls with inconsistent styling
```typescript
// Different button styles across tables
<button className="table-action-btn-small">Edit</button>
<button className="notes-filter-btn">Filter</button>
<button className="task-action">Complete</button>
```
**After:** Standardized Button component
```typescript
import { Button, IconButton } from '../components/ui/Primitives';
// Consistent button styles
<Button variant="ghost" size="sm">Edit</Button>
<Button variant="secondary" size="sm">Filter</Button>
<IconButton icon={<CheckIcon />} label="Complete" />
```
---
## Part 4: Accessibility Improvements
### Keyboard Navigation
**Focus Management**
```typescript
// Ensure interactive elements are focusable
<button
type="button"
tabIndex={0}
onKeyDown={(e) => {
if (e.key === 'Enter' || e.key === ' ') {
e.preventDefault();
handleClick();
}
}}
>
Action
</button>
```
**Keyboard Toggles**
```typescript
<div
role="button"
tabIndex={0}
onKeyDown={(e) => {
if (e.key === 'Enter' || e.key === ' ') {
e.preventDefault();
toggle();
}
}}
aria-pressed={isActive}
>
Toggle Option
</div>
```
### ARIA Labels
**Button Labels**
```typescript
// Icon buttons need explicit labels
<IconButton
icon={<EditIcon />}
label="Edit note"
aria-label="Edit note"
/>
```
**Status Indicators**
```typescript
// Status badges need descriptive labels
<NotelettStatusBadge
status="active"
aria-label="Status: Active"
>
Active
</NotelettStatusBadge>
```
**Form Labels**
```typescript
// All inputs need associated labels
<Field>
<FieldLabel htmlFor="title">Note Title</FieldLabel>
<Input id="title" type="text" />
<FieldDescription>Enter a descriptive title for your note</FieldDescription>
</Field>
```
### Focus Indicators
**Visible Focus States**
```css
/* Ensure focus is visible */
*:focus-visible {
outline: 2px solid var(--nl-focus-ring);
outline-offset: 2px;
}
/* Or use design token */
*:focus-visible {
outline: 2px solid var(--nl-focus-ring);
box-shadow: 0 0 0 2px var(--nl-focus-ring-muted);
}
```
---
## Part 5: Responsive Design
### Shell Breakpoints
**Responsive Shell Testing**
```typescript
const breakpoints = {
mobile: 'max-width: 560px',
tablet: 'max-width: 768px',
desktop: 'min-width: 769px',
};
// Shell adapts at these breakpoints
@media (max-width: 560px) {
.notes-main {
margin-left: 0;
}
.notes-right-panel {
display: none;
}
.notes-sidebar {
position: fixed;
bottom: 0;
width: 100%;
height: 60px;
}
}
```
### Viewport Matrix Testing
**Test all routes across viewports**
```typescript
const routes = ['/notes', '/workspaces', '/tasks', '/relationships'];
const viewports = [
{ name: 'Desktop', width: 1200, height: 800 },
{ name: 'Tablet', width: 768, height: 1024 },
{ name: 'Mobile', width: 375, height: 667 },
];
routes.forEach((route) => {
viewports.forEach((viewport) => {
test(`${route} - ${viewport.name} viewport`, async ({ page }) => {
await page.setViewportSize({ width: viewport.width, height: viewport.height });
await page.goto(route);
// Check for horizontal overflow
const bodyWidth = await page.evaluate(() => document.body.scrollWidth);
expect(bodyWidth).toBeLessThanOrEqual(viewport.width + 10);
// Check main content visibility
const mainContent = page.locator('main');
await expect(mainContent).toBeVisible();
});
});
});
```
---
## Part 6: Testing Infrastructure
### Playwright Setup
**Install Dependencies**
```bash
cd web
pnpm add -D @playwright/test
pnpm exec playwright install chromium
```
**Create Playwright Config**
Create `web/playwright.config.ts`:
```typescript
import { defineConfig, devices } from '@playwright/test';
export default defineConfig({
testDir: './e2e',
fullyParallel: true,
forbidOnly: !!process.env.CI,
retries: process.env.CI ? 2 : 0,
workers: process.env.CI ? 1 : undefined,
reporter: 'html',
use: {
baseURL: 'http://localhost:3045',
trace: 'on-first-retry',
screenshot: 'only-on-failure',
},
projects: [
{ name: 'chromium', use: { ...devices['Desktop Chrome'] } },
{ name: 'firefox', use: { ...devices['Desktop Firefox'] } },
{ name: 'webkit', use: { ...devices['Desktop Safari'] } },
{ name: 'Mobile Chrome', use: { ...devices['Pixel 5'] } },
{ name: 'Mobile Safari', use: { ...devices['iPhone 12'] } },
],
});
```
### Test Suite Structure
Create tests in `web/e2e/` directory:
```
web/e2e/
├── viewport-matrix.spec.ts # Viewport compliance
├── horizontal-overflow.spec.ts # Overflow detection
├── alert-positioning.spec.ts # Critical alerts positioning
├── feedback.spec.ts # Save/delete/update feedback
├── page-states.spec.ts # Loading/empty/error/success states
├── form-validation.spec.ts # Form validation
└── keyboard-navigation.spec.ts # Keyboard navigation
```
### Test Runner Script
Create `scripts/tests/run-e2e.sh` with server lifecycle management:
```bash
#!/bin/bash
set -e
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
PROJECT_ROOT="$(cd "$SCRIPT_DIR/../.." && pwd)"
WEB_DIR="$PROJECT_ROOT/web"
REPORTS_DIR="$SCRIPT_DIR/reports"
TIMESTAMP=$(date +%Y%m%d_%H%M%S)
PORT=3045
cd "$WEB_DIR"
# Kill existing server, start fresh, run tests, cleanup
# ... (same as trading platform script)
```
---
## Part 7: Cipher Design System Integration
### Design Principles
Follow Cipher design system principles for consistent UX across NoteLett:
#### 1. Visual Hierarchy
**Size and Weight**
```typescript
// Use design tokens for consistent hierarchy
<h1 style={{ fontSize: 'var(--nl-text-2xl)', fontWeight: 'var(--nl-font-bold)' }}>
Note Title
</h1>
<h2 style={{ fontSize: 'var(--nl-text-xl)', fontWeight: 'var(--nl-font-semibold)' }}>
Section Header
</h2>
<p style={{ fontSize: 'var(--nl-text-base)', color: 'var(--nl-text-secondary)' }}>
Note content
</p>
```
#### 2. Spacing System
**Consistent Spacing**
```typescript
// Use design token spacing
<div style={{ padding: 'var(--nl-spacing-md)' }}>
Content
</div>
<div style={{ gap: 'var(--nl-spacing-sm)' }}>
<Button>First</Button>
<Button>Second</Button>
</div>
```
#### 3. Typography
**Font Scales**
```typescript
// Use design token font sizes
const textStyles = {
xs: 'var(--nl-text-xs)',
sm: 'var(--nl-text-sm)',
base: 'var(--nl-text-base)',
lg: 'var(--nl-text-lg)',
xl: 'var(--nl-text-xl)',
'2xl': 'var(--nl-text-2xl)',
};
<p style={{ fontSize: textStyles.base }}>Body text</p>
```
#### 4. Color System
**Semantic Colors**
```typescript
// Use semantic color tokens, not literal colors
const statusColors = {
success: 'var(--nl-success)',
warning: 'var(--nl-warning)',
error: 'var(--nl-error)',
info: 'var(--nl-info)',
};
<div style={{ color: statusColors.success }}>Success message</div>
```
