This extension pack packages some of the most popular (and some I find very useful) VS Code Ionic (2.x and 3.x) extensions.
Extensions Included
Ionic + Angular + RxJS Code Snippets
ionic 2 Commands with Snippets - snippets for ionic 2 for TypeScript and HTML. It also provides some basic ionic cli commands (you can run from vsCode command palette).
Angular 2, 4 and upcoming latest TypeScript HTML Snippets - Angular 2, 4 and upcoming latest Typescript HTML ES6 fequently used snippets (very useful specially if you work with route guards and component life cycle hooks - great complement to John Papa's extension above).
rxjs-snippets - Generate Reactivex rxjs code snippets for typescript/javascript.
Template Productivity
Angular Language Service - provides a rich editing experience for Angular templates, very useful when working on Angular HTML template. It works really well with Ionic templates as well.
Auto Close Tag - Automatically add HTML/XML close tag, same as Visual Studio IDE or Sublime Text.
Productivity
Auto Import - Automatically finds, parses and provides code actions and code completion for all available imports (altough VSCode has auto import funcionatlity, this plugin is va great complement).
