No videos. On purpose.

This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on shopify you can find — even without producing a single minute of custom video.

Practitioner-tested, not vendor marketing

This course is built by engineers who ship shopify systems in production. It reflects how these tools actually behave at scale — not how the documentation describes them.

Code you can run, not demos to watch

Every day includes working code examples you can copy, run, and modify right now. The goal is understanding through doing.

Links to the canonical sources

Instead of re-explaining existing documentation, this course links to the definitive open-source implementations and the best reference material on shopify available on the internet.

Completes in 5 one-hour sessions

Each day is designed for about an hour of focused reading plus hands-on work. Do the whole course over a week of lunch breaks. No calendar commitment, no live classes, no quizzes.

The best external videos on this topic.

Instead of shooting our own videos, we link to the best deep-dives already on YouTube. Watch them alongside the course. All external, all free, all from builders who ship this stuff.

Read the source.

The best way to deepen understanding is to read the canonical open-source implementations. Clone them, trace the code, understand how the concepts in this course get applied in production.
