Nullinjectorerror: no provider for httpclient! without app.module.ts

I'm trying to read a JSON in Ionic Angular with HttpClient, but I get this error "nullinjectorerror: no provider for httpclient!".

The issue is that the lastest version of angular doesn't generate app.module.ts.

My code:

import { Component, OnInit } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { IonicModule } from '@ionic/angular';

import { HttpClient } from '@angular/common/http';
import { map } from 'rxjs';

@Component({
selector: 'app-ficha-evento',
templateUrl: './ficha-evento.page.html',
styleUrls: ['./ficha-evento.page.scss'],
standalone: true,
imports: [IonicModule, CommonModule, FormsModule]
})
export class FichaEventoPage implements OnInit {

event:any=[];

constructor(private http: HttpClient) { }

ngOnInit() {
this.getEvnt().subscribe(res=>{
/*console.log("res",res);*/
this.event=res;
});
}

getEvnt(){
return this.http
.get('assets/eventos.json')
.pipe(
map((res:any)=>{
return res.data;
})
)
}

}


Any idea? thanks!!

I'm trying to import HttpClientModule in the page.module.ts, but it doesn't work. I also tried to generate appModule manually... doesn't work either.

Now I'm looking for other ways to acces Json files...
