Complete NestJS noob - questions

[peak meadow]

I am trying to make sense of NestJS. I copied the tutorial code and the Hello World page is loading.
Then I plugged in my custom template engine and I am able to render a page.

Here is one first question: how can the template engine adapter know where templates are located? I need the path to load nested templates.
Or is there a callback function that I can configure the template engine to use for loading template files?

My code so far:

More questions to come... Like what is an "AppService" for?

nestjs is build on top of express, it just complicated stuff more so things can be more categized and better
so you can just follow the express docs mostly

the docs also mention:

views, the directory where the template files are located. Eg: app.set('views', './views'). This defaults to the views directory in the application root directory.

meaning there is a folder called "views" where the templates are read from
and app.set('views', './views') will change the directory

I see a standard callback __express(path, options, callback) and res.render mentioned. Let me hunt that render function

That’s just what express uses for @Render. But I saw that Consolidate.js uses:

file = join(dirname(path), partialPath + extname(path));
