React + Axios POST request example

In my previous article, I have written how to make POST requests in JavaScript using Axios. In this article, we will see how to do the same in React.

Project setup

Create a new react app using the following command:

1npx create-react-app react-axios-post

Install the axios library by running the below command:

1npm i axios

Add the following css in index.css:

index.css

1body {
2  display: flex;
3  justify-content: center;
4}
5.item {
6  display: flex;
7  justify-content: space-between;
8  gap: 20px;
9}

Update the App.js with the following code:

App.js

1function App() {
2  return (
3    <div>
4      <form action="" id="login" method="post">
5        <h1>Login</h1>
6        <p className="item">
7          <label for="email"> Email </label>
8          <input type="email" name="email" id="email" />
9        </p>
10        <p className="item">
11          <label for="password"> Password </label>
12          <input type="password" name="password" id="password" />
13        </p>
14        <p className="item">
15          <input type="submit" value="Login" />
16        </p>
17      </form>
18    </div>
19  )
20}
21
22export default App

Here we have created a form with 2 fields: email and password. Also, we have a button to submit the form.

Handling the form submit

In the below code,

We are storing the email and password in their respective local states.
We have added a submit handler for the form, which calls the API endpoint using Axios with email and password in the request body.

App.js

1import axios from "axios"
2import { useState } from "react"
3
4function App() {
5  const handleSubmit = e => {
6    // Prevent the default submit and page reload
7    e.preventDefault()
8
9    // Handle validations
10    axios
11      .post("https://example.con/login", { email, password })
12      .then(response => {
13        console.log(response)
14        // Handle response
15      })
16  }
17
18  const [email, setEmail] = useState()
19  const [password, setPassword] = useState()
20  return (
21    <div>
22      <form action="" id="login" method="post" onSubmit={handleSubmit}>
23        <h1>Login</h1>
24        <p className="item">
25          <label for="email"> Email </label>
26          <input
27            type="email"
28            name="email"
29            id="email"
30            value={email}
31            onChange={e => setEmail(e.target.value)}
32          />
33        </p>
34        <p className="item">
35          <label for="password"> Password </label>
36          <input
37            type="password"
38            name="password"
39            id="password"
40            value={password}
41            onChange={e => setPassword(e.target.value)}
42          />
43        </p>
44        <p className="item">
45          <input type="submit" value="Login" />
46        </p>
47      </form>
48    </div>
49  )
50}
51
52export default App
