Docs Text

The Angular Language Service is a way to get completions, errors, hints, and navigation inside your Angular templates whether they are external in an HTML file or embedded in annotations/decorators in a string. The Angular Language Service autodetects that you are opening an Angular file, reads your tsconfig.json file, finds all the templates you have in your application, and then provides language services for any templates that you open.

Description

Add support for angular's new language service described in
https://next.angular.io/guide/language-service

This will allow

• Autocompletion
• Error checking
• Navigation
  etc in angular.

Also make sure that non standard html tags won't cause any issues when it is not there in custom.json (at least errors should be replaced with warnings and there should not be any formatting issues). Also html spec don't say that elements and attributes can't have special symbols like []()* etc. consider this also in the html parser.

Also Remove support for old AngularJS 1.x
and
Add inbuilt support for typescript
