WordPress-Posts-React

A lightweight (<3 kb minified!) set of React hooks and components to asynchronously fetch and display WordPress posts using WordPress's most updated REST API.

Why?

Almost all of the other WordPress React libraries I found were either too bloated or too old and unmaintained, which uses outdated mechanisms to retrieve blog articles off WordPress sites. This library is designed to be as lightweight as possible (no dependencies), and provides drop-in components to display posts in a variety of ways directly in your React app.

Installation

You can install the package using yarn or npm:

yarn add wordpress-posts-react
# or
npm install wordpress-posts-react

This will install wordpress-posts-react from the npm registry and add it to your package.json file.

Usage

Common Patterns

The most common pattern is to use the useWordPressFeed hook to fetch posts from a WordPress site, and then use the WordPressBlogroll component to render the posts as a blogroll. The following snippet demonstrates that:

import { WordPressBlogroll, useWordPressFeed } from 'wordpress-posts-react'

const Blogroll = () => {

    const { feed, loading } = useWordPressFeed('https://supertype.ai')

    if(!loading){
    return (
        <main>
            <div>
                <h1>{feed.length} Articles</h1>
                <WordPressBlogroll feed={feed} />
            </div>
        </main>
    )}
    else{
        return <div>Loading...</div>
    }
}

This will fetch the latest 10 posts from the WordPress site at https://supertype.ai and render a beautifully formatted blogroll in your React or Next.js app.

It uses WordPress' officially documented REST API to fetch the posts, so it will always be up to date with the latest WordPress features, returns JSON data (yay! no XML!), ⚡ fast, and with almost no 🚧 maintenance required. Weighing at less than 10kb, it's also 🪶 featherweight, with no dependencies.

• 🎁 Beautifully formatted blogroll
• 📅 Human-friendly dates (e.g. "2 days ago")
• 💨 Uses async and await to fetch posts asynchronously
• 🚀 Uses WordPress's official REST API to fetch posts
• 📦 No dependencies (Less than 10kb in size)

Hooks and Components

useWordPressFeed(site_url, author_id, number_of_posts = 10) is a React hook that asynchronously fetches posts from a WordPress site and returns the posts as an array of objects. Only its first argument is required: the URL of the WordPress site you want to fetch posts from.

• author_id: If specified, this narrows down to WordPress posts of the author you want to fetch posts from. If you don't pass in an author_id, it will fetch posts from all authors.
• number_of_posts: The number of posts you want to fetch. Defaults to 10.

💡 Pro tip: To confirm that the site is in fact a WordPress site, you can append /wp-json to your site (e.g <your-site>/wp-json/) and see if it returns a JSON object. If it does, then you can be sure that the site is a WordPress site. This is the same mechanism that wordpress-posts-react uses to fetch and render the Wordpress posts as an isolated React component.

import { useWordPressFeed } from 'wordpress-posts-react'

// fetches author id=23's latest 10 posts from https://supertype.ai
useWordPressFeed('https://supertype.ai', 23)

// fetches author id=17's latest 5 posts from https://supertype.ai
useWordPressFeed('https://supertype.ai', 17, 5)

WordPressBlogroll({ feed }) is a React component that renders a blogroll of posts. It takes in a feed prop, which is an array of objects that contain the post's title, date, excerpt, and link. Usually used in conjunction with useWordPressFeed to fetch posts from a WordPress site.

import { useWordPressFeed, WordPressBlogroll } from 'wordpress-posts-react'

const { feed, loading } = useWordPressFeed('https://supertype.ai')
{
    !loading &&
        <WordPressBlogroll feed={feed} />
}

There are also a few utility functions that you can use to format dates, parse HTML and decode HTML entities. You are not required to directly use them in your React project, as they are used internally by wordpress-posts-react to format the posts. However, they are exported so you can use them elsewhere in your own React application or roll your own blog components (e.g <YourOwnCustomBlogRoll />) after cleaning the returned json data using these utility functions.

import { useWordPressFeed, timeAgo, 
         parseUrlString, decodeHtml } 
from 'wordpress-posts-react'

const BlogComponent = ({url}) => {
    const { wp_data, loading } = useWordPressFeed(url)
    const [feed, setFeed] = useState([]);

    useEffect(() => {
        if(wp_data && !loading){
            const posts = wp_data.map((post) => {
                const { title, link, date, excerpt } = post;
                    return {
                        id: post.id,
                        title: decodeHtml(title.rendered),
                        link: parseUrlString(link),
                        date: timeAgo(date),
                        excerpt: decodeHtml(excerpt.rendered),
                        // ...other custom attributes post-cleansing
                    };
                });
            setFeed(posts);
        }
    }, [url]);

    return <YourOwnCustomBlogRoll feed={feed} />
    
}
