Complex Project Structure

Now let's say that your application isn't located in a folder called src, but it's located in src/app.

We want to be able to set a different 'root path' to load our configurations from. Be it src or dist.

Imagine a more complex project structure like this:

/
├── dist/
├── src/
│   ├── app/
│   │   ├── app.module.ts
│   │   └── bootstrap/
│   │   │   ├── index.ts
│   │   │   └── bootstrap.module.ts
│   ├── migrations/
│   ├── cli/
│   ├── config/
│   │   ├── app.ts
│   │   └── database.ts
│   └── main.ts
├── tsconfig.json
└── package.json

In this example, config files are located in the /src/config folder, because they are shared between app, migrations and cli scripts.

Also during typescript compilation all files from src/ folder will be moved to the dist/ folder.

Moreover, the ConfigModule is imported in the BootstrapModule, but not directly in AppModule.
