Hey there!

As long as the following conditions can be met in a Salesforce environment, Express should work:

- A call to our authorization server can be made
- JS workers can be loaded
- The salesforce component lives on a single domain

Unfortunately we do not have any sample code for this.

If you have questions or run into problems when trying to implement into Salesforce, please let me know!

Thanks!  
Logan
