Describe the solution you'd like

I want to use ui5 components from server side rendering of Deno and fresh framework. Currently when I try to start the project after installing the npm modules the server fail to start.

It is failing at 3rd party library zxing with the following error:

error: Uncaught (in promise) ReferenceError: window is not defined
    at Object.<anonymous> (file:///home/kesav/.cache/deno/npm/registry.npmjs.org/@zxing/library/0.17.1/umd/index.min.js:1:445)

Watcher Process failed. Restarting on file change...

Is there anyway to exclude the components that are not needed so that we don't get these kind of failures.

Hi @kesavkolla,
thanks for reaching out - I think at the end of the day the error comes down to this upstream dependency issue in UI5 Web Components: SAP/ui5-webcomponents#9771
As soon as this is fixed and released, we should be already pretty close to supporting SSR in Deno :)
