Try it out!

1. Clone or fork arc-react-webpack-demo
2. Run yarn to install packages
3. Run webpack to generate bundles
   • (I committed the generated DIST/ folder so you can view the generated structure, otherwise I'd add it to .gitignore)
4. yarn start to start your server
5. Navigate to http://localhost:2222 to view the app in any device (Chrome Developer Tools' Device Toolbar is an easy way to see the adaptive functionality in action)

Features & Details

• React, Webpack, Express, Babel
• Client/server rendering
• Device detection done with mobile-detect
• Zero media query usage - all resizing done adaptively or with fluid grids

ARC example usage

(under components/, sorted by use case)

• Split layouts due to device size: app-layout/
  • 3 column layout in desktop and ipad; 1 column in mobile
• Split JS due to difference in functionality: header/
  • Due to less available space, mobile web exposes the search bar in a full page overlay, which is accessible by clicking the search icon button at top right
• Different image sizes to decrease page weight when possible: image/
  • Mobile can load a smaller size version of the same image since it doesn't need one as large as larger screens would
• Split CSS due to device size, branding, context: color-changing/
  • Can add any combination of flags to match against based on device type, brand, locale, etc
  • Shared CSS can be put at top level and also required in the template file
• Component only used in one device type: breadcrumbs/
  • Example of something more typical in desktop and less commonly used in mobile context
• Specific branded image/style by device: share/
  • Different icons are quickly recognizable to users of different devices

Gotchas

• Anytime you split resources into folders, you need an index.arc at the top level of the component
• The index.arc proxy config requires a default flag
• Make sure to update flagsets accordingly in webpack.config.babel.js for any combinations you want to adapt for
• All adapting starts from a default file (e.g index.js, style.scss) so you can't skip having one
• If you need to adapt a CSS resource, import it in a JS file - CSS @imports will not get adapted
• File matches are sorted by highest specificity (the most matches in the period delimited path) and alphabetically
• Be careful not to get too ambitious with too much specializing, as it will get harder to keep track of which file loads when
