This post details the GitLab CI pipeline used for this blog, which is built

templates that have evolved over several years for my published NPM packages
with a collection of end-to-end tests used for web applications and a few
unique jobs added specifically for Eleventy and Nunjucks templates. It's meant

There are some cases where the expected outcome of a CI job script is failure.

reported in merge requests.
