Generic type ‘modulewithproviders‘ requires 1 type argument(s).

Query: generic type ‘modulewithproviders<t>’ requires 1 type argument(s).

This error occurs in TypeScript when you are trying to use a generic type ModuleWithProviders<T> without providing the required type argument. The ModuleWithProviders<T> is a generic type used in Angular for modules that provide dependencies.

To fix this error, you need to provide the missing type argument to the ModuleWithProviders<T> type. The type argument should specify the type of the dependency or configuration object that the module provides.

Example:

    import { NgModule } from '@angular/core';
    import { ModuleWithProviders } from '@angular/core';

    // Define a module that provides a service
    export interface MyModuleConfig {
      apiEndpoint: string;
    }

    @NgModule({
      providers: [MyService],
    })
    export class MyModule {
      static forRoot(config: MyModuleConfig): ModuleWithProviders<MyModule> {
        return {
          ngModule: MyModule,
          providers: [
            { provide: 'API_ENDPOINT', useValue: config.apiEndpoint }
          ]
        };
      }
    }
  

In the above example, we have a module MyModule that provides a service and takes a configuration object MyModuleConfig as an argument. The forRoot method returns an instance of ModuleWithProviders<MyModule> with the provided configuration object.

To use this module, you can pass the configuration object when importing the module in your application’s root module:

      import { MyModule } from './my-module';
      import { AppComponent } from './app.component';

      const config: MyModuleConfig = { apiEndpoint: 'https://example.com/api' };

      @NgModule({
        imports: [
          MyModule.forRoot(config),
        ],
        declarations: [AppComponent],
        bootstrap: [AppComponent]
      })
      export class AppModule { }
