Connecting Headless WordPress with Gatsby Cloud: A Comprehensive Guide

Headless WordPress and Gatsby Cloud offer a powerful combination for building fast, scalable, and dynamic websites. This guide will walk you through the process of connecting these two platforms, enabling you to leverage the content management power of WordPress with the performance and flexibility of Gatsby.

1. Setting Up Your WordPress Instance

First, you need a WordPress site to serve as your content source. If you don’t have one already, follow these steps:

• Choose a hosting provider: Look for a provider that offers good performance and security, like Bluehost, SiteGround, or GoDaddy.
• Install WordPress: Most hosting providers offer one-click WordPress installation.
• Set up your basic site: Install themes, plugins, and create the necessary pages and posts.
• Install the WordPress REST API plugin: This plugin enables Gatsby to fetch data from your WordPress site. The official WordPress REST API plugin is a great choice, but several other alternatives are available.

2. Creating a Gatsby Cloud Project

Next, you need a Gatsby Cloud project to build and deploy your website.

• Sign up for Gatsby Cloud: Visit the Gatsby Cloud website and create a free account.
• Start a new project: Choose the "Static Site" option and give your project a descriptive name.
• Connect your GitHub repository: If you plan on using version control, connect your GitHub repository to your Gatsby Cloud project.
• Set up your Gatsby site: Gatsby Cloud will automatically create a starter project based on your chosen template.

3. Integrating Gatsby with WordPress

Now comes the core integration step. This involves configuring Gatsby to fetch data from your WordPress site.

• Install the Gatsby Source WordPress plugin: This plugin allows Gatsby to query your WordPress site’s REST API. Install it by running npm install gatsby-source-wordpress in your Gatsby project’s terminal.
• Configure the plugin: Inside your gatsby-config.js file, add a new source plugin configuration. This configuration specifies your WordPress site’s URL, the REST API endpoint, and any other necessary parameters. An example configuration:

plugins: [
  {
    resolve: 'gatsby-source-wordpress',
    options: {
      baseUrl: 'https://your-wordpress-site.com',
      protocol: 'https',
      hostingWPCOM: false,
      useACF: false,
      verboseOutput: false,
      perPage: 100,
      searchAndReplace: {
        search: 'https://your-wordpress-site.com',
        replace: 'http://your-gatsby-site.com',
      },
    },
  },
],

• Query data in your Gatsby components: Use GraphQL queries within your Gatsby components to fetch content from WordPress. For instance, to fetch all posts:

import React from 'react'
import { graphql } from 'gatsby'

export default function BlogPage({ data }) {
  return (
    <div>
      <h1>Blog Posts</h1>
      <ul>
        {data.allWpPost.nodes.map((post) => (
          <li key={post.id}>
            <a href={post.uri}>{post.title}</a>
          </li>
        ))}
      </ul>
    </div>
  )
}

export const query = graphql`
  query {
    allWpPost {
      nodes {
        id
        title
        uri
      }
    }
  }
`

4. Building and Deploying Your Gatsby Site

Once your integration is complete, you can build and deploy your Gatsby site.

• Build your Gatsby site: Run gatsby build in your project’s terminal to generate the static HTML files.
• Deploy to Gatsby Cloud: Gatsby Cloud will automatically build and deploy your site every time you push code to your repository. You can configure the deployment settings, like branch and environment, in your Gatsby Cloud dashboard.
