Integrate DWS Viewer API with Your Frontend App without a Backend

DWS Viewer API can be used with or without a backend managed by you. To use it without a backend, you first need to upload a document using its dashboard UI.

Uploading a Document to DWS Viewer API

When you create a document via the dashboard, you’ll upload a document via a web browser to DWS Viewer API, which will manage the entire document lifecycle.

1. 1
   You use the dashboard to upload a document to DWS Viewer API, which stores the document.
2. 2
   You use the dashboard to generate an session token for the document.

Viewing a Document in Your Web App

After you create a document and an associated session token, you can open it via the PSPDFKit for Web SDK. Any changes made to the document are automatically persisted by DWS Viewer API.

1. 1
   Your web app is running in a web browser.
2. 2
   The web app loads Nutrient for Web using the session token obtained from the dashboard for authentication.
3. 3
   After successful authentication, it displays the document streamed from DWS Viewer API.
