Fetch List of Employees in React


List of Employees present at some URI i.e http://127.0.0.1:9091/employee/fetch

[{"id"1001,"name""Dinesh","salary"10000.0},{"id"1002,"name""Kumar","salary"10000.0},{"id"1003,"name""Dinesh","salary"10000.0},{"id"1004,"name""Kumar","salary"10000.0}

] 


React Output:

React Code to Fetch this Data:

import React, { useStateuseEffect } from "react";

import UserService from "../services/user.service";


const Employee1 = () => {
  const APIURL = "http://127.0.0.1:9091/employee/fetch";

  const empployee = {
      id: 10013,
      name: "Dinesh",
      salary: 10000.0
  }

  const [empsetEmp] = useState([empployee]);

  useEffect(() => {
      fetchEmployees();
  }, []); // << super important array

  const fetchEmployees = () => {

      fetch(
          `${APIURL}`
      ).then((response=> response.json())
      .then(
        (data=> setEmp(data)
        );

  }

  return (
    <div className="container">
     
  <table>
      {emp.map((emp=> (
                <tr>
                    <td>{emp.id}</td>
                    <td>{emp.name}</td>
                    <td>{emp.salary}</td>
                </tr>
            ))
