Overview

A JavaScript library for Power Apps portals (previously Microsoft CRM Portals). To write basic functions like show and hide in Power Apps portals, we need to rely on jQuery for extensive manipuliation of DOM. The library provides these functionality in simple, clear and readable syntaxes. The library will help developers who are familar with Power Apps client script.
