Project: Zeppelin
Issue Type: Improvement
Reporter: Mukunda Gogoi
h1. Zeppelin Web + Vue JS Prototype
h2. What is Vue JS?
What Vue JS is basically a progressive framework rather than an opinionated
Framework like angular js or ember js
It was Originally created by **Evan You** as a way to be a modern js framework
Something that you could get up and running quickly and get some real results
And at the same time maintain a lot of the things that people love about other
modern js frameworks.
h2. Main features of Vue JS
* Virtual Dom
* Supports data binding (v-bind)
* Component-based
* Computed props
* Router
* Directives
* Watchers
* Templates (HTML based)
* Vuex (similar to redux)
h2. Problems with current Zeppelin Web
* Extensive use of `ng-show` and `ng-repeat` directives degrading performance.
* No virtual dom support every HTML manipulation is done on the actual dom.
* Extensive use of ng-if for hiding and showing elements from UI.
* AngularJS1 is a relatively outdated framework.
* Too many watchers causing ace editor typing performance issues.
* Too many paragraphs with large code and output causes the browser to freeze.
* Overall feel of the UI is very sluggish contributing to bad User Experience.
* Lacks a centralized store.
