How Do You create an unidirectional WordPress website with React?

It's time to do some work and master the art of creating and then launch a bidirectional WordPress website with React.

Prerequisites

Before beginning this lesson ensure that you've got:

• Good understanding of React

Step 1. Install the WordPress Website. WordPress Website

Begin by creating your WordPress website, as it is the primary base of data for the React. React is a program. If you've already established an WordPress site, you may remove this section; otherwise, you'll need comply with these instructions.

When the installation is complete, after which you can access the Dev dashboard, and then select the New WordPress website to create a completely new WordPress website.

Input the necessary information for example, and then press the button to create the website click to proceed.

It can take up to a couple of minutes before the website is created, however once it is up and operating, you'll be able to gain access to it, as an admin panel by clicking "Open Site" and the WP admin options.

In order to enable use of the JSON API, you'll have to modify the URLs of your website.

Additionally, there are tools like Postman to check and submit request via WordPress REST APIs.

Step 2: Configuring the React Application

Once you have your WordPress site operating, it's the time to begin developing the frontend. In this article, we'll be using React to serve as the frontend to the application.

In order to begin by running this code in your terminal. Then, create a React. React app.

npm create [email protected] my-blog-app cd my-blog-app npm install

These commands will build an React application. It will then install the necessary dependencies.

Additionally, you must install Axios as well, it is a JavaScript library that makes HTTP requests. Utilize the following commands to configure it.

NPM installation Axios

For the server to be launched to develop your app, you need to run npm-run dev in the terminal. The server should then initialize your app at http://127.0.0.1:5173.

It is also possible to substitute the code within main.jsx and App.jsx with the following codes:

// main.jsx import React from 'react' import ReactDOM from 'react-dom/client' import App from './App' ReactDOM.createRoot(document.getElementById('root')).render( , )

/http://www.html0.com/ App.jsx import React using'react'export the default method App() return ( ) 

Step 3: Ticking Posts from WordPress

It is time to pull everything from WordPress. WordPress website.

In the App.jsx, add the below state, and also include UseState of React.

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

posts is used to get the post's data from state. setPosts allows you for adding more information in the article. Additionally, we've given an empty array for the state by default.

Then, add this code after the state, in order to fetch posts from the WordPress REST API.

const fetchPosts = () => // Using axios to fetch the posts axios .get("http://headless-wordpress-website.local/wp-json/wp/v2/posts") .then((res) => // Saving the data to state setPosts(res.data); ); // Calling the function on page load useEffect(() => fetchPosts() , [])

This code runs within the fetchPosts() function on page load. In the fetchPosts() function, we create a attempt to send an call to the WordPress API via Axios to find posts. We then return the post content to the original condition that we had previously announced.

Step 4: Designing the Blog Component

In the directory which is root, you may build the directory components and within it, make two documents new: 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( post ) const [featuredImage, setFeaturedimage] = useState(); const getImage = () => axios .get(post?._links["wp:featuredmedia"][0]?.href) .then((response) => setFeaturedimage(response.data.source_url); ); ; useEffect(() => getImage(); , []); return ( new Date(Date.now()).toLocaleDateString("en-US", day: "numeric", month: "long", year: "numeric", ) post.title.rendered ); 

In the code that follows the code above, we've made the card component which takes the blog's posting property, which contains the data about the blog's content. The information is retrieved from the WordPress API. WordPress API.

In using the retrievImage() function, it uses Axios to find the URL for the photo which was featured and store that information in the an appropriate state.

In the end, we added an useeffect hook to call to activate the acquireImage() function once the component has been mounted. We also added the return declaration, which indicates that we are rendering the content of the article, which includes the title excerpt, images as well as the data of the post.

After you've done that then add the style explained below into blog.css. blog.css file:

@import url("https://fonts.googleapis.com/css?family=Poppins"); .blog-container width: 400px; height: 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; height: 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, in the App.jsx file, include the following code within the returns declaration to make the blog part of your return:

 posts.map((item) => ( )) ;

This is how the information you'll have to add it in your App.jsx should appear as:

import React, useEffect, useState from 'react' import axios from "axios" import Blog from './components/Blog'; export default function App() const [posts, setPosts] = useState([]); const fetchPosts = () => axios .get("http://my-awesome-website.local/wp-json/wp/v2/posts") .then((res) => setPosts(res.data); ); useEffect(() => fetchPosts() , []) return ( posts.map((item) => ( )) ) 

Save the file, then refresh your browser's tab. Then you'll be able to view your blog post within the web page.
