NodeInvocationException: document is not defined on initial project startup. But fine after refreshing page (F5) about jsstarterdocker

Problem is associated with running the server side code before webpack is completed compilation. Additionally entire webpack is run when the webserver starts. Need to prevent this to resolve issue.

Do you think a multi-stage docker build might help with this? I'm not 100% familiar with your custom webpack build but I know the baked in Angular bundling is an after effect of successfully compiling the server code.

Would it be possible to trigger the webpack build in the Dockerfile manually before starting the server code compilation?
https://docs.docker.com/develop/develop-images/multistage-build/#before-multi-stage-builds

Essentially what I'm saying is can we strip this functionality from the .csproj and put it into the Dockerfile?

@mtmulch I'd love to remove that setup from the .csproj file and into the docker build. I was trying to figure out at way to do that but no luck. I think this is one of the higher priorities for getting the project running correctly. Its a huge bug that the initial page load is an error message that requires a page refresh. Any help with trouble shooting/ PR is welcome. I would be stoked if this was resolved. 🌮

@bharney Hello friend, starting a new job this week that I might finally be able to call home and back in my own place in Chicago. I'm gonna take a look at some of this stuff soon on some nights when I'm bored.
