Embrace the awesomeness! PDFJS is a global object which you get when you include pdf. This object is the base object and contains various methods. It is used to fetch the PDF document asynchronously, sending multiple Ajax requests to download document in chunks, which is not only fast but efficient as well.

There are different parameters which can be passed to this method but the most important one is the URL pointing to a PDF document. The success callback of the Promise is passed an object which contains information about fetched PDF document. In our example, this argument is named pdf.

You might be wondering if, since the PDF document is fetched in chunks, for documents that are huge in size the success callback would only be called after a delay of quite few seconds or even minutes.

In fact, the callback will fire as soon as the necessary bytes for first page have been fetched. When you provide a valid page number, getPage returns a promise which, when resolved, gives us a page object that represents the requested page. The structure for placing pages rendered as Canvas elements is quite simple.

Add the following two lines to index. Replace page.

We can use the success callback to render text-layers. This returns a promise as well and in success callback of that promise text fragments representation is returned.

TextLayerBuilder is a class which requires some parameters we already have from pdf. The newly created instance of TextLayerBuilder has two important methods: setTextContent , which is used to set text fragments returned by page. In fact, zooming is quite straightforward and we just need to update the scale value.

Increase or decrease scale with your desired factor to alter the zoom level. This is left as an exercise for the reader, but do try this out and let us know how you get on in the comments.
