Как передать uint8array в Mozilla's Viewer.js?

Question

Я разрабатываю PDF Viewer точно так же, как в Angular 5. Для этого я использую viewer.js, предоставленный Mozilla. В viewer.js я загружаю документ pdf из локального хранилища, т.е. из папки "/assets".

Теперь я хочу передать данные (в формате uInt8array), поступающие из некоторых служб REST, в viewer.js. Есть ли способ добиться этого?

1. index.html

2. viewer.js

"use strict";


var DEFAULT_URL = '../assets/files/1.pdf';
;
var pdfjsWebApp = void 0;
{
  pdfjsWebApp = __webpack_require__(4);
}
;
{
  __webpack_require__(8);
}
;
{
  __webpack_require__(9);
}

Строка кода var DEFAULT_URL = '../assets/files/1.pdf' - это место, где я даю файл локали.
