I have used generator-aspnetcore-spa templates for Angular 2 to develop a website. Locally this works fine, F5 in VS debug in the website. But when I deploy this website to Azure through continuous deliver I get the following exception:
Exception: Call to Node module failed with error: To use prerendering, you must install the 'aspnet-prerendering' NPM package.
Error also happened in #144, but locally that works fine for me. My issue is a little different.

I am assuming the error is shown because node_modules is not copied into my package. I didn't include this in my source control (based on best practice advise) and I deploy through VSTS continuous delivery. So I could include node_modules in my source control and be done with it, but I am trying to understand what the correct approach is here.

On the client side webpack bundles all vendor.js which are used and sends those to the client. Is a similar approach possible for node on the server side? Or do I really need the full node_modules? If so, should I restore them during the build? With the command npm install? Or indeed add them to source control? Adding node_modules would make the package a lot bigger, but maybe there is no other solution? Maybe someone else has an idea about this?
