Embedding PDF files in your Angular application. Highly configurable viewer including the toolbar, sidebar, and all the features you're used to.

/**
 * stephanrauh/pdf.js#15: undo and redo buttons for the annotation editor, so
 * touch users can undo without a keyboard. They send pdf.js's own
 * `editingaction` event, the same route Ctrl+Z / Ctrl+Y take. Unlike these
 * shortcuts, which only listen while an editor mode is active, the buttons
 * also work with no editor selected - pdf.js undoes and redoes in that mode
 * too - so they're only disabled when there's nothing to undo or redo.
 *
 * The buttons deliberately don't use the ids `undoButton` / `redoButton`:
 * the bleeding-edge pdf.js toolbar binds its own click handler to these, and
 * each click would undo twice.
