Headless WordPress

Headless-WP is a comprehensive solution that enables you to use WordPress as a headless CMS. It builds on top of next-wp by 9d8dev, which created a demo application specifically for Next.js. Headless-WP is a fork of that project, aiming to create smooth integration with WordPress regardless of the framework used. Under the hood, it utilizes the default WordPress REST API, but responses and requests are primarily typed in TypeScript

Get Started

Once you've installed the package (npm install headless-wp), you can start using the library.

Important! Before making any API calls, set the base URL of your WordPress site by running HeadlessWP.setBaseUrl("https://your-site.com") Replace your-site.com with the URL of your WordPress site

import HeadlessWP from "headless-wp";

HeadlessWP.setBaseUrl("https://your-site.com");
const posts = await HeadlessWP.getAllPosts();
console.log(posts);

Using Next.js / React to display posts list

import HeadlessWP from "headless-wp";

HeadlessWP.setBaseUrl("https://your-site.com");
const posts = await HeadlessWP.getAllPosts();

return posts.map(async (post) => {
  const featuredImage = await HeadlessWP.getFeaturedMediaById(post.featured_media);
  const author = await HeadlessWP.getAuthorById(post.author);
  return (
    <div key={post.id}>
      <img src={featuredImage.source_url} alt={featuredImage.alt_text} />
      <h3>{post.title.rendered}</h3>
      <p>{author.name}</p>
      <div
        dangerouslySetInnerHTML={{
          __html: post.excerpt.rendered,
        }}
      ></div>
    </div>
  );
});
