Design System Creation

This helps you build a design system from scratch with the full stack: foundation layer (typography, colors, spacing), component library, and governance model. You'd reach for this when you're working across multiple products or teams and need design consistency without rebuilding buttons and forms everywhere. It includes documentation templates and versioning guidelines, which honestly is where most design systems fall apart. The spacing scale starts at 4px increments and the component examples cover the usual suspects like buttons, inputs, and modals. One thing to know: it pushes you to start small with essentials rather than building 50 components nobody asked for, which is the right call.

Overview

A design system is a structured set of components, guidelines, and principles that ensure consistency, accelerate development, and improve product quality.

When to Use

Multiple product interfaces or teams
Scaling design consistency
Reducing redundant component development
Improving design-to-dev handoff
Creating shared language across teams
Building reusable components
Documenting design standards

Quick Start

Minimal working example:

Design System Structure:

Foundation Layer:
  Typography:
    - Typefaces (Roboto, Inter)
    - Font sizes (scale: 12, 14, 16, 20, 28, 36, 48)
    - Font weights (Regular, Medium, Bold)
    - Line heights and letter spacing

Colors:
  - Primary brand color (#2196F3)
  - Secondary colors
  - Neutral palette (grays)
  - Semantic colors (success, error, warning)
  - Dark mode variants

Spacing:
  - Base unit: 4px
  - Scale: 4, 8, 12, 16, 24, 32, 48, 64px
  - Apply consistently across UI
