Gatsby Theme Catalyst Blog

This adds a blogging interface using MDX, similar to gatsby-theme-blog-core with some custom modifications. The theme can be added to any existing Catalyst-based site and will add blog functionality. This is a minimal implementation that is not designed to be used in a production site, but rather as a jumping off point for a production site.

The main features added to this blog theme are:

  • Support for a featured image on the blog posts
  • Support for a social image on the blog posts
  • Support for categories and tags
  • Support for different post types in the frontmatter to allow for conditional styling of posts
  • Drafts flag in frontmatter so you can keep posts in your repo that are drafts and not built in the final site
  • Ability to control the excerpt length used in post summaries




Theme options

Option Values Description
contentPath String Defaults to “content/posts”, determines where the posts are created from.
assetPath String Defaults to “content/assets”, determines where the post assets like images are located.
basePath String Defaults to “/blog”, determines the page location for the post list.
excerptLength String Defaults to “140”, determines the length of the excerpt use for post summaries.
postListTitle String Defaults to “Posts”, allows you to control the title of your post page, e.g. “Blog” or “Writing” or “Digital Garden”

About Gatsby Theme Catalyst

The Catalyst series of themes and starters for GatsbyJS were designed to provide an opinionated set of integrated themes and starters that can be used to accelerate your next Gatsby project. The vision is for one “core” theme in which most dependencies and components are contained followed by progressively more styled and refined child themes and starters. These themes rely heavily on Theme-UI and MDX.
