Key Links

• Live App
• Live Storybook
• Storybook (via Chromatic)
• GitHub Repo
• Trello Board
• HedgeDoc
• LinkedIn Profile

Technical Architecture

• Chakra UI
  • Accessibile by design
  • Themeable
  • Light wrapper around Flexbox/CSS Grid
  • Pre-built and battle tested atomic components - why reinvent the wheel?
• Storybook
  • Serves as "living documentation"
  • Integrates with Chromatic for seamless visual regression testing
  • Great developer experience. Work on one component in isolation
• Create React App
  • Fast, first-party way to bootstrap a new React App
• React Query / Axios / Mock Service Worker
  • nice APIs, caching, IE11 compatibility

Features

• Accessible
  • Chakra UI components
  • Markup landmarks, aria-label, alt tags
  • Keyboard navigation
• Theming
  • Ensure consistency with design system
  • Dark Mode (branded with Boolean colors)
• Code Quality Tooling
  • Husky: pre-commit/pre-push hooks
  • TypeScript
  • Eslint (custom configuration pulled in via npm)
• Details
  • Interactive reply field on posts
  • Togglable like/save buttons on posts
  • Icon svgs taken from Instagram
  • Cursor hover states/text underlines matched to real Instagram site
  • Loading skeleton components
  • Deterministically generate avatars from the username for more variety
  • Color mode-aware custom favicon (doesn't change with color mode switcher, uses the system color mode)

Approach

• Create Trello board
• Identify components to build
• Setup app and tooling
  • Remove boilerplate
  • Project structure
  • Linting
  • Pre-commit/pre-push hooks (husky)
  • Add dependencies
• Add Storybook
• Mock API Data
• Create components
• Create/integrate app/views to API (or Mock API in Storybook)
• Publish
• Finish documentation (some was as I went along)

Future Improvements

• Make the app fully-responsive. If this were a real project, I'd have built it mobile-first.
• Add tests (Not too many. Mostly integration.)
• Add translations for react-i18next - currently the i18n library is configured, but no translations have been added
• Structure app by feature - currently everything is in src/components, however Storybook groups the stories by feature
