Delete Data Di Preact Dengan Rest Api Di Preact Dan Laravel — Part 6

Membangun aplikasi web di era modern memerlukan pondasi yang kokoh. Framework modern memberikan fleksibilitas luar biasa bagi developer untuk menghadirkan fitur kompleks secara cepat tanpa mengabaikan aspek keamanan dan keandalan sistem.

Tahapan Implementasi & Walkthrough Kode

Berikut adalah langkah demi langkah teknis yang dapat Anda ikuti langsung pada codebase Anda:

Tahap 1: Penulisan Kode & Konfigurasi

//import useState dan useEffect
import { useState, useEffect } from "preact/hooks";

//import api
import api from "../../services/api";

//import Link
import { Link } from "preact-router/match";

export default function PostIndex() {
  //init state
  const [posts, setPosts] = useState([]);

  //define method
  const fetchDataPosts = async () => {
    //fetch data from API with Axios
    await api.get("/api/posts").then((response) => {
      //assign response data to state "posts"
      setPosts(response.data.data.data);
    });
  };

  //run hook useEffect
  useEffect(() => {
    //call method "fetchDataPosts"
    fetchDataPosts();
  }, []);

  //method deletePost
  const deletePost = async (id) => {
    //delete with api
    await api.delete(`/api/posts/${id}`).then(() => {
      //call method "fetchDataPosts"
      fetchDataPosts();
    });
  };

  return (
