Project 1 — Enterprise Design System & Component Library

Build a fully documented, accessible, and distributable UI design system package:

Bootstrap Core
    ↓
Sass Configuration (_variables.scss, maps, mixins)
    ↓
Design Tokens (Figma -> Style Dictionary -> SCSS Variables)
    ↓
Custom Theme (Brand Palette, 8pt Spacing, Custom Radii)
    ↓
Components (Buttons, Inputs, Selects, Modals, Dropdowns, Tabs, Tooltips, Tables, Cards, Navigation, Forms, Alerts)
    ↓
Component Variants (Solid, Outline, Ghost, Destructive)
    ↓
Accessibility Audits (WCAG 2.2 AA Compliance, axe-core)
    ↓
Storybook Living Documentation
    ↓
npm Package Distribution (@enterprise/ui)

Key Architectural Implementation:

// packages/design-system/src/theme.scss
@import "tokens/tokens.scss";
@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/maps";
@import "bootstrap/scss/mixins";
@import "bootstrap/scss/utilities";

// Token mappings
$primary: var(--token-color-primary);
$body-bg: var(--token-color-bg);
$body-color: var(--token-color-text);
$border-radius: var(--token-radius-base);

@import "bootstrap/scss/root";
@import "bootstrap/scss/reboot";
@import "bootstrap/scss/type";

                Bootstrap Core
                    ↓
              Design Tokens
                    ↓
        ┌───────────┼───────────┐
        ↓           ↓           ↓
     Default      Dark       Brand Neon
        ↓           ↓           ↓
         Component Wrapper Layer
                    ↓
             React / Vue 3
                    ↓
         Multi-Tenant SaaS

Dynamic Theme Switching Implementation:

// Runtime multi-brand theme engine
export function setBrandTheme(brandId, mode = 'light') {
  const root = document.documentElement;
  root.setAttribute('data-bs-theme', mode);
  root.setAttribute('data-brand-theme', brandId);
  localStorage.setItem('user-brand', brandId);
  localStorage.setItem('user-color-mode', mode);
}

Storybook Architecture & Configuration Recipe

// .storybook/main.ts
import type { StorybookConfig } from '@storybook/react-vite';

const config: StorybookConfig = {
  stories: ['../src/**/*.stories.@(js|jsx|mjs|ts|tsx)'],
  addons: [
    '@storybook/addon-links',
    '@storybook/addon-essentials',
    '@storybook/addon-interactions',
    '@storybook/addon-a11y' // Mandatory for automated WCAG AA compliance auditing
  ],
  framework: {
    name: '@storybook/react-vite',
    options: {}
  }

🔥 Modern Frontend Developer Priority Stack:

Bootstrap 5
├── 12-Column Responsive Grid
├── Mobile-First Breakpoints
├── Spacing & Flexbox Utilities
├── Core UI Components
├── Accessible Forms & Validation
├── Sass Variable Overrides
├── Custom Utilities API
├── CSS Custom Properties & Theming (data-bs-theme)
├── WCAG 2.2 AA Accessibility
└── Component Library Architecture

Senior Takeaway: You do not need to memorize every single Bootstrap CSS class name. The foundational skill is mastering the underlying CSS & responsive layout principles, then using Bootstrap's modular architecture to implement enterprise design systems with speed, reliability, and precision.
