Inkscape is an open-source vector design app, with a good range of freehand and path-based drawing tools. The update adds support for multi-page documents and batch export, a new Tiling effect for creating repeating patterns, and streamlines workflow for layers, object alignment and editing colour gradients.Īn increasingly powerful open-source vector drawing package Then it's just a matter of reading it back from the Stripe API when I get the 'purchase completed' webhooks in order to build the correct attachments and send the customer their assets via email.The Inkscape team has released Inkscape 1.2, the latest version of the open-source vector design tool. That means instead of a database, I can just store the entire purchased pattern directly within the Stripe transaction within the `client_id` field using this compressed representation.

This means that any pattern can be represented by a single short string like `w:1440!h:900!x:random!v:0.63!c:0.06!s:9gjk5s!f:sp!i:0.30` and reproduced with 100% accuracy. The thing that makes that possible is that I'm using a seedable PRNG for the pattern generation and have a custom serialization format for all of the possible pattern parameters. One thing that folks may find interesting about this project on a technical level is that it's fully stateless including the backend that's responsible for interacting with Stripe Checkout, processing payments, and sending emails with receipts and links to re-download patterns.
