webpack build errors after installing firebase-admin "npm run webpack:server" - missing dependancies

Question

I have an angular universal app. During build I am getting all kinds of errors after trying to use firebase-admin on the server. For some reason i can get the server to build when firebase-admin is required.

build angular unversal server

webpack --config webpack.server.config.js --progress --colors

errors

I think something like this might be a good solution but i dont know webpack that well. https://stackoverflow.com/a/44450118/3066142

this was also good info. but nothing helpful. If i cannot compile with webpack then what is another way of doing this? https://github.com/googleapis/google-cloud-node/issues/1821

update I modified webpack.server.config.js so node_modules do not bundle.

const nodeExternals = require('webpack-node-externals');

module.exports = {
   ...
   externals: [nodeExternals()],
   ...
}

i think that fixed the problem above because the app was able to bundle without error. But now when i run the build there is an error at run time

Error: Cannot find module 'zone.js/dist/zone-node'
