Web-Atoms Core

Lightweight JavaScript framework with MVU Pattern with Data Binding in JSX.

Note, MVVM is now deprecated, we have realized that MVVM often adds more code then the benefits. Since JavaScript allows mixin, its easy to incorporate reusable logic with mixin rather than MVVM. MVU pattern is better suitable for faster development.

  1. Data Binding, simple arrow functions to bind the UI elements
  2. Styled Support
  3. AtomRepeater - Lightweight List Control to manage list of items
  4. Chips control
  5. Dual View support (Mobile and Desktop)
  6. Smallest syntax
  7. Faster rendering
  8. Simple Data Validations
  9. RetroFit inspired REST API Support
  10. No additional build configurations
  11. Event re routing, it helps in reducing number of event listeners on page.
  12. UMD and SystemJS Module Loader
  13. Packer, to pack all JavaScript in single module along with dynamic module loader support
  14. FetchBuilder, fetch builder allows you to build REST request in fluent way and execute them with single await.

Web Controls

  1. ComboBox (wrapper for SELECT element)
  2. AtomControl (base class for all other controls)
  3. AtomRepeater
  4. PopupWindow, PopupWindowPage


  1. WindowService - to host AtomWindow and retrieve result
  2. RestService - RetroFit kind of service for simple ajax
  3. BrowserService - An abstract navigation service for Web and Xamarin

Development guidelines

  1. Use TypeScript module pattern

  3. Organize single module in single TypeScript file
  4. Import only required module and retain naming convention
  5. Use default export for UI component
  6. No Atom.get and Atom.set
  7. Do not use underscore _ anywhere, not in field name not in get/set
  8. Do not use set_name method name, instead use get name() and set name(v: T) syntax for properties.
