I followed the steps, and it doesn't work. I think it's better to edit the article with necessary additional steps.
Things that don't work for me:
The code uses Webpack, but there's no webpack.config.js. When calling npm run build, there will be an error about the Webpack config not being found. I had to follow the steps described in Mark Johnson's comment to get the Webpack to work.
npm run build
Tutorial part 1 uses Morgan in server.js, but in this part 2, Morgan is removed from the dependencies. As a result, running node server will have an error. I realized that Morgan is included in the source code, though. So it seems that the code in the article is not exactly the same with the source code?
