`server.js` broken 😢

Just ran:
```sh
npm start
```

Got:

```
> word-finder@1.0.3 start
> node server.js

node http server listening on http://localhost:3000
imported a bunch of words! >> 235887
request.url: /

throw er; // Unhandled 'error' event

# Context:

I'm revisiting this project to update it ahead of working on a `search` feature for `day-job work-work` ... 🏦 🔍
Just want to have a stable baseline in `JS` that I can point people to a basic example ... 🔗
Only going to spend `T25m` on trying to get this working again. 🧑‍💻 ⏳
If I can't get it working, will just update the `README.md` and archive. 📂
