Browser side of Online Editor

While researching for WYSIWYG online editor of DOCX files, I find this demo Edit A Document Online: Word, PDF, HTML
From the documentation links on the page, they are all pointing to the backend APIs.
I want to find out more details on how to embed the Javascript Online Editor into our Web Application.
Could you point me to the relevant documentation, please?

We already subscribed to the Aspose.Total on Java, need to know how to connect this Javascript Online Editor to our backend.
Thanks.

@yachan I am afraid sources of Aspose.Words Editor and Viewer demos are not currently available. We are currently working on actualizing the demo applications. The task is logged as WORDSNET-24764 . We will keep you updated and let you know once the demos are updated. Please accept our apologies for your inconvenience.
