Hire GatsbyJS Developers

Gatsby is a React-based static site generator and web framework. In the WordPress world, Gatsby is used to build headless WordPress front ends – WordPress manages content and exposes it via WPGraphQL, and Gatsby pulls that content at build time to generate a static HTML site that is deployed to a CDN.

Gatsby’s architecture is fundamentally different from Next.js. Where Next.js supports both static generation and server-side rendering, Gatsby is primarily static – all pages are built at deploy time, resulting in pure static files that require no server-side rendering on each request. This makes Gatsby sites extremely fast and secure (no server to attack), but it means content changes in WordPress require a rebuild to appear on the front end.

Gatsby’s data layer uses GraphQL throughout the framework, which pairs naturally with WPGraphQL on the WordPress side. The gatsby-source-wordpress plugin is the official integration, handling authentication, media processing, and content type mapping between WordPress and Gatsby’s GraphQL data layer.

Gatsby + WordPress development work typically involves:

• Building a headless WordPress front end with Gatsby – configuring gatsby-source-wordpress, building page templates, and deploying to Netlify or Gatsby Cloud.
• Setting up incremental builds – configuring Gatsby to only rebuild changed pages rather than rebuilding the entire site on every WordPress content change.
• Building custom Gatsby components for WordPress content types – blog layouts, custom post type displays, taxonomy archive pages.
• Performance optimisation on an existing Gatsby + WordPress site – image processing configuration, build time optimisation, and front-end performance work.
• Migrating from Gatsby to Next.js – a project some teams undertake as Gatsby’s market share relative to Next.js has shifted.

Gatsby’s market position relative to Next.js has changed significantly. Gatsby was the dominant headless WordPress framework in 2019-2021; Next.js has taken a larger share since. Look for developers who have recent Gatsby experience, not just historical knowledge from when Gatsby was more widely used.

Ask specifically about their experience with gatsby-source-wordpress (the current official integration) as opposed to older Gatsby WordPress approaches that used the REST API directly. The gatsby-source-wordpress plugin works with WPGraphQL and has a specific configuration and troubleshooting approach.

For build time and incremental builds, ask how they have handled large WordPress sites where full rebuilds take a long time. Gatsby’s build times increase with content volume, and managing builds for large sites requires specific configuration.

• Build failing with GraphQL errors – the WPGraphQL schema has changed (a plugin update changed what fields are available), or a Gatsby query is referencing a field that does not exist in the current schema. Check the WPGraphQL schema and update the Gatsby query.
• Content changes not appearing after rebuild – the rebuild did not complete successfully, or only an incremental build ran and missed the changed content. Check the build log on Netlify or Gatsby Cloud for errors.
• Images not loading or loading slowly – Gatsby’s image processing is not correctly configured for WordPress media, or the image source URL is blocked. Check the gatsby-config.js image configuration.
• Build time becoming unmanageably long – the WordPress site has grown significantly and full rebuilds now take too long. Configure incremental builds and review image processing settings, which are often the largest contributor to build time.
• gatsby-source-wordpress failing to connect – WPGraphQL is not installed or activated on the WordPress site, or the WordPress URL in gatsby-config.js is incorrect. Verify WPGraphQL is active and the URL is reachable from the build environment.

Gatsby releases major versions that require migration work. Gatsby 5 (the current major version) introduced React 18 support and the Slice API. Projects on Gatsby 4 or earlier need migration work to benefit from current Gatsby features and security updates.

gatsby-source-wordpress updates alongside WPGraphQL updates. When WPGraphQL releases a major update, gatsby-source-wordpress typically needs a corresponding update. Running mismatched versions causes data fetching errors.

Netlify and Gatsby Cloud (now Netlify, after Gatsby was acquired) handle hosting and build pipeline maintenance. Build minutes usage should be monitored to avoid unexpected overage charges on frequent rebuilds.

When posting a Gatsby project on Codeable, specify the Gatsby version and deployment platform (Netlify, Gatsby Cloud, or self-hosted). Also mention the WordPress data source (WPGraphQL via gatsby-source-wordpress, or custom REST API). For existing projects, include the build time and any recent build failures – these are the most common issues that need developer attention on mature Gatsby sites.
