HTTP Service ​

Overview ​

The HTTP service is responsible for making API requests to fetch, create, update, and delete data from the backend. It extends HttpServiceBase from @k5cjs/store to ensure consistency and reuse across different entities.

Defining the HTTP Service ​

The HTTP service interacts with the API and maps responses to the expected format.

Example HTTP Service Definition ​

import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
import { Observable, map } from 'rxjs';

import { ActionInit, HttpParams, HttpServiceBase, Params } from '@k5cjs/store';

import { User } from './users.type';

@Injectable({ providedIn: 'root' })
export class HttpService extends HttpServiceBase<User> {
  constructor(private _http: HttpClient) {
    super();
  }
}

import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
import { Observable, map } from 'rxjs';

import { ActionInit, HttpParams, HttpServiceBase, Params } from '@k5cjs/store';

import { User } from './users.type';

@Injectable({ providedIn: 'root' })
export class HttpService extends HttpServiceBase<User> {
  constructor(private _http: HttpClient) {
    super();
  }
}

See Also:

• users.type.ts – Defines the User type structure.

Explanation ​

• HttpServiceBase<User> extends the base HTTP service functionality for handling API requests.
• HttpClient is injected to make HTTP calls to the backend.
• User represents the entity type managed by this service.

Using the HTTP Service ​

The HTTP service is used inside effects to manage API calls efficiently.

Conclusion ​

By extending HttpServiceBase, the HTTP service provides a structured way to interact with the API, ensuring consistency and efficiency.
