If the entity isn't already established in this conversation, ask which entity (it must match the one exposed by up-api's CRUD endpoints).
up-app/src/app/services/<entity>.service.ts:
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';
export interface <Entity> {
id?: number;
// one field per column from the Day 1 entity spec
}
@Injectable({ providedIn: 'root' }) export class Service { private base = 'http://localhost:8080/api/s'; constructor(private http: HttpClient) {}
getAll(): Observable<[]> { return this.http.get<[]>(this.base); }
getById(id: number): Observable<> { return this.http.get<>(${this.base}/detail/${id}); }
save(item: ): Observable<> { return this.http.post<>(${this.base}/save, item); }
update(id: number, item: ): Observable<> { return this.http.put<>(${this.base}/update/${id}, item); }
delete(id: number): Observable { return this.http.delete(${this.base}/${id}); }
}
Register `provideHttpClient()` in `app.config.ts` if it isn't already there. No redeploy needed for this step.
