Medusa is a commerce platform with a built-in customization framework — perfect study material for our e-commerce course graduates. Instead of rebuilding carts, orders, and payments from scratch, you compose them from Medusa's modules and focus on what makes your store unique.
Why download it: see how production commerce architecture really looks — modules, API routes, admin extensions — in TypeScript/Node.js. Run it locally, break it safely, and steal patterns for your own builds.
Get started: clone the repo, follow the official docs to boot the backend and admin, then explore the modules folder. MIT-licensed core, free to learn from and build on.
