# CASA

A framework for building forms based on the [GOV.UK Design System](https://design-system.service.gov.uk/).

## Features

- Adopts the [GOVUK Design System](https://design-system.service.gov.uk/) which provides well-researched, accessible markup out of the box
- Handles complex journey routing so you can easily tailor users' journeys to provide the best experience
- Multi-language support
- A small core, but highly extensible through hook and plugin mechanisms
- Built on ExpressJS so offers a shallow learning curve
- Distributable supports both ES6 and CommonJS codebases

## Getting started

```bash
npm -E @dwp/govuk-casa
```
