The Patchwork Development Kit makes working with Patchwork a breeze. With just a few commands you can quickly scaffold a new project, generate solidity contracts, generate frontend and backend code to interact with those contracts, and spin up a functional Docker container to start testing everything end-to-end.

Overview

create-patchwork is the fastest way to build a full-stack Patchwork application, generating everything you need for a deployable onchain app in minutes.
