About the project

Shadow Style Shop sells printed T-shirts online, without a physical store, and prints designs that buyers send in themselves. The catalogue has seven collections and more than a hundred prints, and the owner adds new ones from the panel. No ready-made template handled the custom order well: the buyer has an image and wants to see it on the shirt before paying.

The configurator runs on a Fabric.js canvas, with the library served from the same server. The buyer moves and scales the image over a shirt mockup and picks the shirt colour and print position, separately for front and back. Both sides are exported as images and sent in one request, which gets a reference number and goes into the database. The owner gets it by email with both designs attached and can reply with a quote without opening the panel.

What I built

• Quantity discount from three shirts up, shown in the cart while you shop; the server works out the final price and ignores any price the browser sends
• Uploads checked by their real content type, whatever the extension says, and stored where they can't be executed
• An admin panel that installs as a PWA, for products, collections, orders, configurator requests and messages
• Messages linked to the shop mailbox both ways: a reply written in the panel goes out as real email, and incoming mail comes back into the same thread
• JPEG, WebP and AVIF made from every uploaded product photo, with the server sending whichever the browser supports
• Clean URLs through a small router, with the .php redirect written so the server's internal rewrite can't loop
