Quick method for importing components and modules

While developing my app using @angular/cli, I have noticed that as the app size increases, it becomes increasingly tedious to specify the paths for imports of components, modules, and scss files.

For instance, when the component structure becomes deep, the import statements can get quite long, like

import {something} from '../../../../someComponent'

.

Is there a way to define these paths in a more succinct manner, similar to how a schema can be defined?

For example, in a file called Schema.json:

{
"someComponent": "../../../../someComponent",
"otherComponent": "../../"
}

With this setup, we could import components directly as

import {someComponent} from 'someComponent';

making it easier to import them anywhere in the project.

Is there a method or approach that allows for this kind of simplified path definition in Angular?

Directories can be specified in the tsconfig.json file:

{
  "compilerOptions": {
    ...,  
    "directories": {
      ...,
      "@utilities/*": ["utilities/*"],
      "@styles/*": ["styles/*"]
    }
  }
}

Afterward, import using absolute paths from utilities/ or styles/ instead of relative paths to the current file:

import {HelperFunctions} from "@utilities/functions";

You have the ability to utilize barrels within your application.

For instance, consider your component:

// heroes/folder/deep/another/deep/folder/hero.component.ts
export class HeroComponent {}

Now, you can create a barrel in any directory of your project that exports this module (typically named index)

export * from './heroes/folder/deep/another/deep/folder/hero.component.ts'; // relative path to current folder

You are free to define multiple barrels as needed.
