The example demonstrates how promises can be used to handle errors during loading.
It also demonstrates how to wait until a page is loaded and rendered.

## Trying the Viewer
With the prebuilt or source version, open `web/viewer.html` in a browser and the test pdf should load. Note: the worker is not enabled for file:// urls, so use a server. If you're using the source build and have node, you can run `npx gulp server`.
