ReactUSWDS Component Library

This is a frontend component library, built in React with Typescript, based on design patterns defined by the United States Web Design System (USWDS) 2.0. Our primary goal is to document and provide common UI components following the USWDS specification. This library removes a significant amount of overhead UI development for projects based on this standard.

A deployed instance of the ReactUSWDS Storybook is located at: https://trussworks.github.io/react-uswds/

An example application, built with React-USWDS, can be found in the /example folder and run with the appropriate yarn:example commands.

Install

Install this package with npm or yarn:

yarn add @trussworks/react-uswds

or

npm i @trussworks/react-uswds

Pre-Release

Pre-release packages are published to GitHub Packages every time code is pushed to the main branch. To use, you will need a GitHub access token with the read:packages scope.

1. Create an .npmrc with

//npm.pkg.github.com/:_authToken=YOUR_TOKEN_GOES_HERE
@trussworks:registry=https://npm.pkg.github.com

or

Create a .yarnrc file with

"@trussworks:registry" "https://npm.pkg.github.com"

2. In your package.json, use "@trussworks/react-uswds": "next"

See GitHub Packages with npm docs for more detailed information.

Usage

It is strongly suggested applications use the same version of USWDS that was used to build the version of ReactUSWDS they're using. A version mismatch may result in unexpected markup & CSS combinations.

You can import ReactUSWDS components using ES6 syntax:

import { Alert } from '@trussworks/react-uswds'

Warning: Do not include USWDS JS in your project alongside this library (i.e., using import 'uswds'), as that will result in some components that use JS (such as the ComboBox) to initialize twice.

Also make sure to include the following in order to import the compiled CSS from this project:

@import '~@trussworks/react-uswds/lib/index.css';

If you aren't already using USWDS as a dependency, you also need to import USWDS styles. Read more info about using USWDS styles and assets here

Background

The primary deliverable is a published npm package that can be included as a dependency in other projects that use USWDS with React. In order for these components to be useful, they should follow best practices for accessible, semantic, markup; be well-tested across browsers and devices; and allow for an appropriate level of customization. We adhere to a set of development guidelines as much as possible and use automation to enforce tests, linting, and other standards.

Non-Goals

This is not meant to be a one-size-fits-all front end solution, We are starting off with the opinionated decision to cater towards projects that use the U.S. Design System 2.0, and encapsulate these specific styles and markup in React components.

In the process, we expect to gain learnings around how to best abstract out UI code from implementation; how to better standardize and document front end code practices; and how to develop, maintain, and distribute a shared JS library in alignment with our company values at Truss.
