Framework support

Nutrient Web SDK is compatible with all JavaScript frameworks, including React, Angular, Vue, Svelte, Electron, Ruby on Rails, TypeScript, and others. It just needs a DOM container to append the viewer, which is possible with any framework.

Operational modes

Nutrient Web SDK can be used standalone or with Document Engine. In standalone mode, all rendering and processing runs entirely on the client side, in the browser. With Document Engine, these operations are delegated to the backend.
