Quick Start

The best way to start is to clone this repo:

git clone https://github.com/usds/gastby-uswds-ts-starter.git your-project-name

Development

To start the project locally:

1. Git clone the starter repo (above) in a terminal
2. If you don't have node 18, install and verify that node -v return 18.x. You can use nvm or asdf
3. run nvm use 18
4. Ensure that pnpm and gatsby-cli are globally installed:

$ npm list -g --depth=0
/Users/username/.nvm/versions/node/v18.12.1/lib
├── [email protected]
├── [email protected]
├── [email protected]
└── [email protected]

5. run pnpm install
6. run pnpm clean && pnpm start

Open http://localhost:8000 with your browser to see the result.

Documentation

Directory Structure

• __helpers__ — Helpers files for testing configuration.
  
• __mocks__ — Mocks for testing.
  
• .github — GitHub configuration including the CI workflow.
  
• .husky — Husky configuration and hooks.
  
• src — Application source code, including pages, components, styles.

Scripts

• pnpm start — Starts the application in development mode at http://localhost:8000.
• pnpm build — Compile your application and make it ready for deployment.
• pnpm serve — Serve the production build of your site
• pnpm clean — Wipe out the cache (.cache folder).
• pnpm type-check — Validate code using TypeScript compiler.
• pnpm lint — Runs ESLint for all files in the src directory.
• pnpm format — Runs Prettier for all files in the src directory.
• pnpm test — Run tests with Vitest.
• pnpm test:watch — Run tests on watch mode.

Path Mapping

TypeScript are pre-configured with custom path mappings. To import components or files, use the @ prefix.

import { Button } from '@/components/Button';

// To import images or other files from the static folder
import avatar from '@/static/avatar.png';

USDS Specific

• works with trusswork components
• can use USWDS tokens as mixins in sass modules (at component level)
• works with i18n using format.js (react-intl)
• has a generator script to quickly create components

Before each commit run the following:

• pnmp run type-check
• pnmp run lint
• pnmp run format
• pnmp run test
• pnmp run intl:extract

i18n

The steps involved with creating i18n content is as follows:

1. Use react-intl as demonstrated in various pages and/or components.
2. When new content is added, run pnpm intl:extract. This will update the json object in lang/en-US-extract.json.
3. Run pnpm intl:createEnJson. This will modify the extracted JSON file into an AST that the library expects and remove console errors.
4. Translate the en-US.json file to an es-MX.json. Each key from the en-US.json file should have a spanish value in es-MX.json.

Deployment

Currently this repo is using Github actions (see .github/workflows in the root directory) for deployment to AWS with the support of Geoplatform.

These actions will

1. creates a staging link (see deploy-staging.yml) as a comment in every PR made against main that passes all checks (type-check, linting, testing, format, commit messages)
2. update the production folder on AWS
3. remove any artifacts of the PR when the PR is closed (see close-pr.yml)

In order for these actions to work as is, the following secrets need to be added in your repo:

1. AWS_ACCESS_KEY_ID
2. AWS_SECRET_ACCESS_KEY
3. STAGE_SITE_URL

The AWS_ACCESS_KEY_ID and the AWS_SECRET_ACCESS_KEY will allow for programmatic (via CLI) access to your AWS resources. See the programmatic access section on here.

The STAGE_SITE_URL should point to the name of your S3 bucket or CDN.
