Class: Rx

Defined in: rx/rx.ts:16

Rx — Reactive expression builder.

Builds template expressions like "{{ count + 1 }}" or "{{ user.name }}" that are evaluated client-side by the prefab renderer.

Usage: rx('count') → "{{ count }}" rx('count').add(1) → "{{ count + 1 }}" rx('user').dot('name') → "{{ user.name }}" rx('items').length() → "{{ items | length }}" rx('price').currency('USD') → "{{ price | currency:'USD' }}" rx('active').then('Yes', 'No') → "{{ active ? 'Yes' : 'No' }}"
