Developing with Gatsby

Gatsby is a highly flexible static site generator that uses ReactJS under the hood. Pages are implemented as React components and the whole site is bundled as a single page app (SPA), but also uses a static site build process to render a static HTML version of the site. The result is a static site that is SEO friendly, but whose UI is hydrated into a React SPA once a page is loaded.

Gatsby is a Departure From Convention-based SSGs

Unlike Hugo and Jekyll, which build a static HTML website based on a specific structure of markdown files, Gatsby can be configured to work any way you want.

Out of the box, a vanilla Gatsby install will generate an HTML page for each .js file located in its src/pages directory. These .js files should export a React component containing the markup for the page. However, Gatsby allows a developer to customize the behavior of the SSG at the build stage, using its createPage API to create pages from a variety of data sources, such as different types of files or even data from a remote API.

Gatsby is Focused on Performance

One of Gatsby’s primary goals is to make it easy to create a performant website via a pre-configured, highly optimized asset pipeline. In this way, Gatsby can be seen as a successor to create-react-app with some additional features to enable static site generation.

…But Not at the Build Stage

It should be noted that Gatsby users typically experience slower build times compared to a site built with Hugo or Jekyll. Due to Gatsby’s flexibility, build times will vary widely, depending on your setup.

Choose Gatsby if you:

  • Plan to use an advanced asset pipeline
  • Want to build your templates with React
  • Want full control over what pages are built by your SSG, and where.
  • Are building a Progressive Web App as opposed to a content-driven website

Don’t choose Gatsby if you:

  • Have a site with a large number of pages and want fast build times
  • Don’t want to work with React or GraphQL
  • Want a website that runs little to no JavaScript on the client side

Currently in Beta

Support for Gatsby in Forestry is currently in closed beta, but you can follow us on Twitter or join our community Slack to be the first to know when Gatsby support becomes available for everyone!
