nullinjectorerror no provider for httpclient angular 17

In Angular 17 where the standalone true option is set by default, the app.config.ts file is generated in src/app/ and provideHttpClient(). We can be added to the list of providers in app.config.ts Step 1: To provide HttpClient in a standalone app we could do this in the app.config.ts file, app.config.ts: import { ApplicationConfig } from '@angular/core'; import { provideRouter } from '@angular/router'; import { routes } from './app.routes'; import { provideClientHydration } from '@angular/platform-browser'; //This (provideHttpClient) will help us to resolve the issue import {provideHttpClient} from '@angular/common/http'; export const appConfig: ApplicationConfig = { providers: [ provideRouter(routes), provideClientHydration(), provideHttpClient () ] }; The appConfig const is used in the main.ts file, see the code, main.ts : import { bootstrapApplication } from '@angular/platform-browser'; import { appConfig } from ...

Why doesn't App Module exist in Angular 17?

Today, I just started exploring Angular version 17 using ng new and found a problem for the newly created project using the command - ng new. The problem is: Path "/src/app/app.module.ts" does not exist while doing ng add in the Angular project. The ‘ng new’ does not generate app.module.ts in the src root folder Angular CLI 17.0.0. From Angular 17 onwards, standalone is now the new default for the CLI . So when we create a new project ‘ app.module.ts ’ file will not create Path " /src/app/app.module.ts ". Run the following command to create the new project including the file ‘app.module.ts’ in your project: ng new AngularMap --no-standalone Note: Here ‘AngularMap’ is the project name I created. Standalone components are a feature introduced in Angular version 14. Now the changes applied in angular 17 default, the Angular team strongly recommends using them as they are easier to use, and understand.
