Now Prototype It is a fully configurable, high fidelity prototype kit for in-browser prototyping. It has a plugin system and a variant system which together allow anyone to take a design system and create a prototype kit from it.
This project is the GOV.UK Frontend Adaptor for Now Prototype It. It allows you to use the GOV.UK Frontend library in your prototype kit.
You can create a new kit by creating an empty directory and running the following command in it:
npx nowprototypeit --variant=@nowprototypeit/govuk-frontend-adaptor create
This will create a new kit using the GOV.UK Frontend Adaptor to give you a GOV.UK Frontend based prototype kit.
