Gatsby Casper Starter

Code Climate Issue Count Conventional Commits

A blog starter for Gatsby, utilizing the popular Casper (v1.4) theme authored by The project is based on Gatsby Advanced Starter and has a lot on common with the Gatsby Material Starter, but will evolve separately. In this project the single Casper CSS file has been carefully extracted into individual components with only minor tweaks.

This starter also serves as example for the Gatsby-Pagination library.

Demo website.


GatsbyJS V2

This starter currently supports GatsbyJS version 2, which brings progressive web app features such as automatic code and data splitting (by route), prefetching, with service worker/offline-first support and PRPL pattern.

More information on Gatsby can be found here.

GatsbyJS legacy support

This project uses Semantic Versioning which align with major version of GatsbyJS. Thus, GatsbyJS v1 support can be found in 1.x.x releases of this starter, while GatsbyJS v2 support will be found in 2.x.x releases.

Special thanks to hnspn for migration the project to support Gatsby v2. 🤘

Posts are authored using Markdown and include some optional YAML frontmatter data properties. Each post should have a separate folder for the .md file in addition to any images or other media related to that post. Posts are stored in a subfolder in the /content/ directory; the target subfolder is set by the blogPostDir property in SiteConfig.js.


Each post can reference the author of the post, if the author is not set the default author will be used; which is controlled by the blogAuthorId property in SiteConfig.js. All authors, including the default author (aka blodAuthorId) must have an author JSON file. These JSON files MUST be stored in a folder names authors, for Gatsby to parse them correctly. The location of this authors folder can be controlled by the blogAuthorDir property in SiteConfig.js. It IS possible to have the authors folder inside the blogPostDir folder.
