Technical Stack II

I wrote about the technology used to publish and host this blog in “Technical Stack”. In the last week, I’ve moved from building with Jekyll and deploying to GitHub Pages to building with Gatsby and deploying to AWS S3.


Because I no longer use Jekyll, I don’t need to maintain a Ruby environment on my system or in Docker. Dependencies can be upgraded automatically via Greenkeeper, a tool I use for other Node.js projects, rather than via Depfu. My new publishing workflow does not rely on the Dropbox client or API.

I moved my homepage to Gatsby too. This allowed me to share stylesheets, images, and other assets (e.g. robots.txt) between both sites. Gatsby is more flexible than Jekyll about image paths, so images now appear inline in my Markdown editor. Also, I can publish posts and images at the same time.


Federico Viticci writes articles in Markdown and publishes them using Git, the same technologies I use to produce this blog. He has spoken and written about his workflow. The tools he uses are powerful, but the publishing process is straightforward. I adopted a similar approach for this blog.

I write in iA Writer on macOS and iOS. My posts are saved in the iA Writer folder in iCloud. Drafts are stored at the top-level. Publishing is a two-step process that begins by dragging a completed post from the top-level into the Published subdirectory. The second step is platform-dependent.

On macOS, Hazel syncs the iA Writer/Published folder in iCloud to a hidden .posts/Published folder1 in a local clone of my Git repository.

On iOS, Working Copy bi-directionally syncs the iA Writer/Published folder in iCloud and the .posts/Published folder in my Git repository2. I can pull, commit and push via a Siri Shortcut.

Committing and pushing to the GitHub remote will trigger a Travis CI build and deployment. When that completes, the latest files will be uploaded to S3, cached by CloudFront, and viewable here.

Next steps

I have several ideas for future improvements:

Travis CI builds this blog in stages. First, it builds and runs tests. Next, built files are deployed to a pre-production environment where tests are run again. Finally, files are promoted from the pre-production environment to the production environment and tests are run again. The entire process takes sixteen minutes to complete. I’d like it to finish in less than three.

gatsby-plugin-s3 is a Gatsby plugin for uploading files built with Gatsby to an S3 bucket. Although unofficial, it is actively developed. I haven’t compared gatsby-plugin-s3 with my Python-and-Bash deploy script, but I’d like to stop maintaining my own deploy script and the Python environment it requires.

gatsby-remark-vscode is a Gatsby plugin for applying syntax highlighting to code blocks from Markdown. It’s very new, but thoughtfully-designed and built by a talented developer I know personally. Here is the story behind the development of gatsby-remark-vscode.

Previously, this site could be accessed without an Internet connection. This was accomplished with the ServiceWorker API. Gatsby provides an official plugin for this—gatsby-plugin-offline—but I haven’t tried it yet.

Previously, I used a separate subdomain for this blog ( Now, the blog is served from a subdirectory ( I’m still deciding which option better suits current and future content (e.g. apps, podcasts). If I opt to serve content from a subdomain, I’ll need to investigate rewrite rules via Lambda@Edge.
