Great introduction. I think Nest is something that I'll look into for my next project. As someone who spends a lot of time in Angular, I love that Nest embraces the full power of TypeScript.

Just FYI: it is not dependency injection(DI) that assigns the appService constructor param to this.appService. That's just a typescript feature that lets you specify private/protected/public on constructor arguments that will make them available as members of the class. What the DI does is instantiate instances over your services/controllers etc and 'injects' them into the constructors. basically you never call new on anything that is provided and the DI system takes care of that as well as controlling the scope of the instances. There are 3 scopes.

1. Singleton: every time you inject it will be the same instance of the service across the entire app
2. Request: a new instance of the service is created for every request but if multiple places in one request inject the service they will be the same instance
3. Transient: every time the service is injected a new instance is created

Use 'any' in typescript mode it great idea 👍😉
Thx for video. Very interesting to compare these awesome frameworks 💡🤗

NestJS gives me Spring vibes which is a framework I didn't like but TypeScript support looks nice. Express with TypeScript feels nice to me.
