@maskspy make sure you run npm install in the project directory. This will download all of the required dependencies listed in the package.json file.

There are many branches in this repository, each corresponding to the start of one of my video lessons. part-3-start branch is the state of the repo at the start of my Part 3 lesson.

For branches try git checkout part-3-start then you have to root again into that folder and go through following to avoid the error you mentioned.
run : npm install
run: node server/server.js
run: npm run serve
Now open you browser localhost:3000 you should be good to go.

In simple words, your command should be "node server/server.js"
