What are the issues causing trouble for my modules, services, and more in Angular ^17?

As I was going through the themes, I couldn't find a similar question. My issue revolves around Angular's inability to locate modules and services that are created using "ng g". Everything seems to be correctly set up, but errors or warnings keep popping up.

The service itself contains multiple methods (functions):

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root'
})
export class NameServices{...}

How should I import this service into a component:

import {NameServices} from '../../@core/utils/NameServices.service';

The problems encountered in the console are as follows:

▲ [WARNING] Import "NameServices" will always be undefined because the file "src/app/@core/utils/NameServices.service.ts" has no exports [import-is-undefined]

    src/app/pages/home/home.component.ts:5:9:
      5 │ import {NameServices} from '../../@core/utils/NameServi...
        ╵          ~~~~~~~~~~~~~~~~~~~~~~~


X [ERROR] TS1490: File appears to be binary. [plugin angular-compiler]

    src/app/@core/utils/NameServices.service.ts:0:0:
      0 │
        ╵ ^


X [ERROR] TS2306: File '*:/Projects/client/src/app/@core/utils/NameServices.service.ts' is not a module. [plugin angular-compiler]

    src/app/pages/home/home.component.ts:7:38:
      7 │ ...rvices} from '../../@core/utils/NameServices.service';

I have attempted various fixes including manual path configurations in tsconfig, changing module versions, etc., which usually lead to more complications.

Is it necessary to adjust dependencies in App.module.ts?

(It appears to be functional, but these console logs are frustrating.)

PS: tsconfig.json

  "include": ["./src/app/@core/**/*"],

Answer №1

It was a quick and straightforward choice. The clash between Angular and JSDoc was the deciding factor. I discovered that tags like @param were causing readability issues within the framework.

I observed that the file's encoding plays a role as well. For instance, Cyrillic characters result in errors when using windows 1252, but there are no issues with utf-8 encoding!

Answer №2

import {
  ProductService
} from '../../@core/services/ProductService';

@Component({
  selector: 'my-component',
  standalone: true,
  imports: [
    ProductService
  ],
  templateUrl: './my.component.html',
  styleUrl: './my.component.scss',
})

export class MyComponent {

  constructor(private productService: ProductService) {}

}
