Hello.  
I am trying the SPA SDK Sample.  
The functions createAuth0Crient and Auth0.isAuthenticated are not enclosed in exception handling blocks.  
Do they not throw any exceptions?  
Where can I find the documentation about that?  
Thank you.

Hi @yfujita,

The documentation for that library can be found here:

[https://auth0.com/docs/libraries/auth0-single-page-app-sdk](https://auth0.com/docs/libraries/auth0-single-page-app-sdk)

and here:

> **[@auth0/auth0-spa-js](https://auth0.github.io/auth0-spa-js/)**
>
> Documentation for @auth0/auth0-spa-js

The first link mentions:

> You can also create the client directly using the `Auth0Client` constructor. This can be useful if:
> 
> - You wish to do custom error handling.

The material you gave me I had already read.  
I have reread it and there is no mention of throwing exceptions.  
I understood this to mean that I should code under the assumption that exceptions are thrown.  
Thank you.
