  • ⚡️ Gatsby 5
  • ⚛️ React 18
  • ⛑ TypeScript

  • 📏 ESLint — To find and fix problems in your code
  • 💖 Prettier — Code Formatter for consistent style
  • 🐶 Husky — For running scripts before committing
  • 🚓 Commitlint — To make sure your commit messages follow the convention
  • 🖌 Renovate — To keep your dependencies up to date (needs to be set up)
  • 🚫 lint-staged — Run ESLint and Prettier against staged Git files (under development)
  • 👷 PR Workflow — Run Type Check & Linters on Pull Requests
  • ⚙️ EditorConfig - Consistent coding styles across editors and IDEs
  • 🗂 Path Mapping — Import components or images using the @ prefix

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. run cd your-project-name
  3. If you don't have node 18, install and verify that node -v return 18.x. You can use nvm or asdf
  4. run nvm use 18
  5. 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]
  1. run pnpm install
  2. run pnpm clean && pnpm start

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

  • __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

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.

The Github actions currently expect an S3 bucket to exist. When setting up the S3 on AWS, you can specify the name and the region. Each action requires this name and region to be set as environment variables:

  1. AWS_BUCKET_NAME
  2. AWS_REGION

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.
