ViewState.toProps will give you a JSON representation of the view that you can save for later reuse.
To restore the view and apply it to a Viewport, do something like:

const viewClass = await imodel.findClassFor<typeof ViewState>(savedViewProps.viewDefinitionProps.classFullName, undefined);
if (viewClass) {
  const view = viewClass.createFromProps(savedViewProps, imodel);
  await view.load();
  viewport.changeView(view);
}
