Hi, I used the https://radmie.github.io/ng-knob/ ng-knob library in ionic-v1 project, but know i want to use the same library in ionic3 project. Is that possible to use the angular.js library in angular2 or angular4?
No. AngularJS is completely different from Angular.
But this exists: https://github.com/RadMie/ng-knob/pull/23
