React fetch data from API and display in a table

We will make use of jsonplaceholder for our APIs.

Project setup

Create a react app using the following command:

npx create-react-app react-fetch-data-table

Add the following styles in index.css:

body {
  margin-top: 20px;
  display: flex;
  justify-content: center;
}

Calling the API

We will use the browser fetch API inside the useEffect hook to call the API to fetch data.

import { useEffect, useState } from "react"

function App() {
  const [users, setUsers] = useState([])
  const [loading, setLoading] = useState(false)
  useEffect(() => {
    setLoading(true)
    fetch("https://jsonplaceholder.typicode.com/users")
      .then(response => response.json())
      .then(json => setUsers(json))
      .finally(() => {
        setLoading(false)
      })
  }, [])

  return <div className="App"></div>
}

export default App

Here we are calling the API and setting the response to the users state.
We also have a state named loading to display a loading text when the data is being fetched.

Displaying the data

In the code below, we are looping the users' array using map and displaying the user details in a table

import { useEffect, useState } from "react"

function App() {
  const [users, setUsers] = useState([])
  const [loading, setLoading] = useState(false)
  useEffect(() => {
    setLoading(true)
    fetch("https://jsonplaceholder.typicode.com/users")
      .then(response => response.json())
      .then(json => setUsers(json))
      .finally(() => {
        setLoading(false)
      })
  }, [])

  return (
    <div className="App">
      {loading ? (
        <div>Loading...</div>
      ) : (
        <>
          <h1>Users</h1>
          <table border={1}>
            <tr>
              <th>Name</th>
              <th>Email</th>
              <th>Phone</th>
            </tr>
            {users.map(user => (
              <tr key={user.id}>
                <td>{user.name}</td>
                <td>{user.email}</td>
                <td>{user.phone}</td>
              </tr>
            ))}
          </table>
        </>
      )}
    </div>
  )
}

export default App

Now if you run the app, you will see the data being displayed in a table:
