Papito (पपितो) = Papaya

Deprecated : No Longer Maintained

Build Status

A Vue & React inspired Frontend Web Framework in Rust for the WASM platform. Developed by a beginner for beginners.

Goals

  • Beginner Friendly. Draws cues from Vue and React.
  • Pure Rust web apps.
  • Cargo only (without webpack). Should provide optional tools that mimic loaders such as file-loader, style-loader, url-loader.

It is still under active development. So tread carefully.
