Step 2: Setting Up a React Application

Now that we’ve were given our WordPress internet content material prepare, we can get began running on the frontend. As mentioned above, in this tutorial we will be the usage of React for the frontend of our application.

To get started, run the underneath code for your terminal to create a React application.

npm create vite@latest my-blog-app 
cd my-blog-app 
npm arrange

The above directions will create a React application and arrange the required dependencies.

We moreover wish to arrange Axios, a JavaScript library for making HTTP requests. Run the underneath command to place in it.

npm arrange axios

Now, so that you could get began the advance server, you’ll be capable to run npm run dev inside the terminal. The server must then initialize your app at

Next, open your challenge for your favorite code editor and delete any pointless files that you just don’t need, such since the assets folder, index.css, and app.css.

You’ll be capable to moreover exchange the code inside of number one.jsx and App.jsx with the following code:

// number one.jsx
import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App'

// App.jsx

import React from 'react'

export default function App() {
  return (

Step 3: Fetching Posts From WordPress

Now it’s time to fetch the posts from our WordPress internet content material.

During the App.jsx, add the underneath state and import useState from React:

const [posts, setPosts] = useState([])

useState is a integrated hook in React that is used so that you could upload states to a component, a state when it comes to knowledge or a assets.

posts is used to get the data from the state, and setPosts is used so that you could upload new knowledge to put up. We’ve moreover passed an empty array to state by the use of default.

Next, add the following code after the state to fetch the posts from the WordPress REST API:

const fetchPosts = () => {
    // The use of axios to fetch the posts
      .then((res) => {
        // Saving the data to state

  // Calling the function on internet web page load
  useEffect(() => {
  }, [])

The above code is working the fetchPosts() function on internet web page load. During the fetchPosts() function, we send a GET request to the WordPress API the usage of Axios to retrieve posts and then save to the statewe declared earlier.

Step 4: Creating a Blog Section

Throughout the basis checklist, create a brand spanking new folder named portions, and within it, create two new files: blog.jsx and blog.css.

First, add the following code to blog.jsx:

import axios from "axios";
import React, { useEffect, useState } from "react";
import "./blog.css";

export default function Blog({ put up }) {
  const [featuredImage, setFeaturedimage] = useState();

  const getImage = () => {
     .get(put up?._links["wp:featuredmedia"][0]?.href)
     .then((response) => {

  useEffect(() => {
  }, []);

  return (

{new Date("en-US", { day: "numeric", month: "long", three hundred and sixty five days: "numeric", })}

{put up.determine.rendered}

); }

Throughout the above code, now now we have created a card aspect that takes the posts assets that contains the main points concerning the blog put up from the WordPress API.

Throughout the getImage() function, we use Axios to fetch the URL of the featured image and then save that wisdom to state.

Then, we added a useEffect hook to call the getImage() function as quickly because the aspect has mounted. We moreover added the return statement during which we’re rendering the put up knowledge, determine, excerpt, and image.

Next, add the categories underneath to the blog.css document:

@import url(" members=Poppins");

.blog-container {
  width: 400px;
  peak: 322px;
  background: white;
  border-radius: 10px;
  box-shadow: 0px 20px 50px #d9dbdf;
  -webkit-transition: all 0.3s ease;
  -o-transition: all 0.3s ease;
  transition: all 0.3s ease;

img {
  width: 400px;
  peak: 210px;
  object-fit: cover;
  overflow: hidden;
  z-index: 999;
  border-bottom-left-radius: 10px;
  border-bottom-right-radius: 10px;

.blog-title {
  margin: auto;
  text-align: left;
  padding-left: 22px;
  font-family: "Poppins";
  font-size: 22px;

.blog-date {
  text-align: justify;
  padding-left: 22px;
  padding-right: 22px;
  font-family: "Poppins";
  font-size: 12px;
  color: #c8c8c8;
  line-height: 18px;
  padding-top: 10px;

.blog-excerpt {
  text-align: justify;
  padding-left: 22px;
  padding-right: 22px;
  font-family: "Poppins";
  font-size: 12px;
  color: #8a8a8a;
  line-height: 18px;
  margin-bottom: 13px;

Then, inside the App.jsx document, add the observe code inside the return statement to render the blog aspect:

{ => ( ))}

In any case, that’s what your App.jsx must seem to be:

import React, { useEffect, useState } from 'react'
import axios from "axios"
import Blog from './portions/Blog';

export default function App() {
  const [posts, setPosts] = useState([]);

  const fetchPosts = () => {
      .then((res) => {

  useEffect(() => {

  return (
{ => ( ))}

Save the document and refresh your browser tab. Now you’ll have to be capable to see your blog posts rendered on the internet web page.
