TypeScript PDF.js Viewer

PDF.js Express is a commercial PDF web viewer that wraps around the PDF.js open-source rendering engine. It offers developers a way to quickly add annotation, e-signatures, and form filling to their TypeScript PDF viewer. It is compatible with any JavaScript framework, including a superset like TypeScript, by using a DOM element to place the document viewing component.
