Hey. Your project is not in latest Angular. @ng-toolkit supports Angular 6+. Please update to the latest Angular version 😃

Angular 8 here, same issue. Not sure if it matters, but when I ran ng add @ng-toolkit/universal I had a ton of ts errors (mostly implicit anys and unused references) in the generated server.ts and prerender.ts files.

Error: Cannot find module 'require("./server/main")'

In your webpack.server.config.js (temporary solution)

replace

  externals: {
    './dist/server/main': 'require("./server/main")'
  },

with this

  externals: {
    './dist/server/main': './server/main'
  },

everything worked fine with me. I got rid of the error - Cannot find module 'require("./server/main")' by correcting code in the ‘server.js’ file.

module.exports = require("require(\"./server/main\")"); to

module.exports = require('./server/main'); i used ‘ng-toolkit/universal’ and after running ‘npm run server’ i got same error.

@LegolasTheElves There is lack of angular.json file in your repository. Please, push it. Thanks in advance!
