  • Create a new React JS project.
  • Import Axios into your React component
  • Use Axios to make HTTP requests.

Let’s start with the first step.

Step 1: Create a new React JS project.

First you have to install the React project. You should use create-react-app command to create a new React project.

npx create-react-app my-app
cd my-app
npm start

Step 2: Import Axios into your React component.

After installing Axios, you have to import your React component. To do this, add the following line to the top of your component file.

import axios from "axios";

Step 3: Use Axios to make HTTP requests.

The code you provided is a function named createPost which uses Axios to make a POST request to the specified URL.

function createPost() {
    axios
      .post(baseURL, {
        title: "Hello World!",
        body: "This is a new post."
      })
      .then((response) => {
        setPost(response.data);
    });
}

ReactJS use axios example.

This code below is an example, When the Create Post button is clicked the createPost function is called. This function makes a POST request to the API with a title and body for the new post. The result of the POST request is also stored in the POST state variable using setPost.

App.js

import axios from "axios";
import React from "react";

const baseURL = "https://jsonplaceholder.typicode.com/posts";

export default function App() {
  const [post, setPost] = React.useState(null);

  React.useEffect(() => {
    axios.get(`${baseURL}/1`).then((response) => {
      setPost(response.data);
    });
  }, []);

  function createPost() {
    axios
      .post(baseURL, {
        title: "Hello World!",
        body: "This is a new post."
      })
      .then((response) => {
        setPost(response.data);
      });
  }

  if (!post) return "No post!"

  return (
    <div>
      <h1>{post.title}</h1>
      <p>{post.body}</p>
      <button onClick={createPost}>Create Post</button>
    </div>
  );
}
