-This is a super simple angular 8 component for displaying pdfs inline(embedded) OR in a new tab along with a feature rich viewer. It uses mozilla's pdfjs viewer(v2.2.171) behind the scenes and supports angular(2/4/5/6/7/8). Extremely lightweight, easiest to integrate and use, most reliable, this library has only one dependancy (@angular/core).
