I was asking "robocop2018". Are you him?

I am not "him" :) though I work at PDFTron

As Nick says the project is open source (https://github.com/PDFTron/webviewer-ui).

Express is available under under dual AGPL/commercial license ( similar to iText and lot's of other popular OSS )

There is no mention of AGPL anywhere in that repository. There is just a LICENSE file with a completely different proprietary license: it is not open source at present. If you intend to make it open source, you need to change the license to an open source one.

Where is the AGPL license?

It's https://opensource.org/licenses/AGPL-3.0 Or summary of what it means bit.ly/2JD0Yj0

If you are talking about info on the site & git, we are working on it. There will be many changes over next few weeks. Stay tuned :)

Yes, I'm familiar with the license.

The question was about your claim that it was already licensed under it. Apparently it's not, but you're "working on it". Umm, okay.
