**Detailed description of issue**  
Hi guys, I am launching a WebViewer instance, and wonder if it contains the total number of pages of the document the instance loads.

**Expected behaviour**  
I found a getPageCount() method but on the “DocumentViewer” class… wondering if there is something similar I could call when I create an instance of the Web viewer:

```
WebViewer(
    {
        etc
    },
    viewer.current,
).then((instance) => {
     --> I need to get the loaded doc's total page count in here

```

**Does your issue happen with every document, or just one?**  
Any document.

**Link to document**  
Not applicable.

**Code snippet**  
WebViewer(  
{  
etc  
},  
viewer.current,  
).then((instance) =\> {  
 → I need to get the loaded doc’s total page count in here

Thanks!
