Jenie

A mighty tinny web components framework/library.

Name Change From Jenie To Oxe

Pleas see Oxe for future development https://www.npmjs.com/package/oxe

Features

  • Really Small 8.09KB gzipped and 27.08KB uncompressed
  • In browser ES6/ESM module and template strings support

Support

  • IE10~
  • IE11
  • Chrome
  • Firefox
  • Safari 7
  • Mobile Safari

Note

Loader uses XHR and new Function to load on-demand and execute modules. If your worried about security please read the linked articles. In summary the articles support not using new Function/eval to process client input. So as long as your only importing local modules (Loader enforces this) then the safety concern is eliminated.
