- when running Gatsby locally during development
- on Netlify before deploying
- on CircleCI after deploying against the newly deployed URL
The deployed sites itself has the 3 mini blog posts that describe the local setup, the Netlify command and how Netlify triggers CircleCI build using a webhook after each deploy.
So read the blog posts https://gatsby-blog-0a5be4.netlify.com/, explore the source, and ping me with any questions.
