neo.mjs covid-dashboard

A multithreading Dashboard showing countries affected by COVID-19.

Switch the Main tabs (Table, Gallery & Helix). When selecting a country inside the top-left SelectField, this will update the route, triggering a selection update on the active view. Selecting an item inside the active view will adjust the route as well, updating the SelectField as well. Switching tabs will adjust the current selection.

The App supports the dark & light themes.

You can configure and sort the gallery & helix with the controls on the right side, resulting in a firework of CSS3 transitions.

This is a perfect performance demo for the webworkers driven UI framework neo.mjs.
