## Use this template

Requires **Node.js 22.12 or newer** and **pnpm 10**.

Click **"Use this template"** on GitHub to create your own repository, then run the setup wizard:

```bash
pnpm install
node scripts/init-agency.mjs   # configure your agency name, domain, and identifier links
pnpm dev
```

Your site will be at `http://localhost:4321`.

### Pick a release

Every release line targets one major Astro version. Start from the newest line
for the Astro version you want to build on:

| Starter release | Astro | Node | Notes |
|---|---|---|---|
| [`v3.x`](https://github.com/ctrimm/astro-gov-starter/releases/latest) | Astro 7 | ≥ 22.12 | **Current** — bilingual seed content, translatable collections |
| [`v2.x`](https://github.com/ctrimm/astro-gov-starter/releases/tag/v2.1.0) | Astro 7 | ≥ 22.12 | Superseded by v3.x; English-only seed content |
| [`v1.x`](https://github.com/ctrimm/astro-gov-starter/releases/tag/v1.0.0) | Astro 6 | ≥ 18.17.1 | Maintenance only |

Two lines target Astro 7 because v3.0.0 made a breaking change of its own — see
[Upgrading from 2.x](./CHANGELOG.md#upgrading-from-2x). New projects should start
from `v3.x`.

```bash
# start from a specific release instead of the default branch
git clone --branch v3.0.0 --depth 1 https://github.com/ctrimm/astro-gov-starter.git
```

See [CHANGELOG.md](./CHANGELOG.md) for what changed in each release, and
[RELEASING.md](./RELEASING.md) for how releases are cut.

## Quick start (from template)

1. Click **Use this template** → **Create a new repository**
2. Clone your new repo and install:
   ```bash
   git clone https://github.com/YOUR-ORG/YOUR-REPO.git
   cd YOUR-REPO
   pnpm install
   ```
3. Run the agency setup wizard:
   ```bash
   node scripts/init-agency.mjs
   ```
   This updates `src/config/site.ts` with your agency name, domain, and the
   seven required [USA Identifier](https://designsystem.digital.gov/components/identifier/) links.
4. Replace seed content in `src/content/` with your programs and FAQs.
5. `pnpm dev` — live preview at `http://localhost:4321`
6. `pnpm build` — production build in `dist/`

---

## Configuration

All agency-specific settings live in one file:

```ts
// src/config/site.ts
export const siteConfig = {
  name: 'Department of Human Services',
  shortName: 'DHS',
  domain: 'dhs.state.gov',
  description: 'Programs and services for eligible residents.',
  locale: 'en-US',

  // Required links for the USA Identifier footer component
  links: {
    about: '/about/',
    accessibility: '/accessibility/',
    foia: 'https://www.foia.gov/',
    noFear: 'https://www.eeoc.gov/no-fear-act-data',
    oig: 'https://www.oversight.gov/',
    privacy: '/privacy/',
    budget: '/',
    usagov: 'https://www.usa.gov/',
  },
} as const;
```

## Deploy

### GitHub Pages (included)

Push to `main`. The workflow in `.github/workflows/deploy-pages.yml` deploys automatically.
Enable Pages: **Settings → Pages → Source: GitHub Actions**.

> **⚠️ Security headers:** GitHub Pages does **not** support custom HTTP response
> headers, so the headers in `public/_headers` (clickjacking protection via
> `frame-ancestors`, `X-Frame-Options`, HSTS, etc.) are silently ignored on
> GitHub Pages. They only take effect on Netlify or Cloudflare Pages. If you need
> these protections — and production government sites should have them — deploy
> to a host that supports response headers, or put a CDN/reverse proxy (e.g.
> CloudFront) in front of Pages and set the headers there.

### Cloud.gov Pages

```yaml
# federalist.json
{
  "build": {
    "command": "pnpm install && pnpm build",
    "destination": "dist"
  }
}
```

### Netlify / Vercel

Both auto-detect Astro. Set **build command** to `pnpm build` and **publish directory** to `dist`.

### Any static host (S3, CloudFront, Azure Blob)

```bash
pnpm build   # outputs to dist/
```
Upload the contents of `dist/` to your bucket or CDN origin.

---

## Search

Site search is powered by [Pagefind](https://pagefind.app/). The `pnpm build`
script indexes `dist/` after the Astro build and writes the index to
`dist/pagefind/`. Results are served at `/search/` (English) and `/es/search/`
(Spanish) — Pagefind splits the index by each page's `<html lang>`, so each
locale searches its own content.

- Search only works on a **production build** (`pnpm build && pnpm preview`);
  the dev server has no index.
- The CSP includes `'wasm-unsafe-eval'` because Pagefind runs its index as
  same-origin WebAssembly (this does **not** allow JavaScript `eval()`).
- No third-party requests: the index and UI are self-hosted static files.

---

## Forms

The contact form (`/contact/`) and eligibility screeners (`/apply/*`) are
**accessible scaffolding only** — they do not submit anywhere out of the box.
Before launch, wire the `action` attributes to your backend of choice
(Formspree, API Gateway + Lambda, your agency's form service, etc.). Look for
the `TODO (M3)` comments in `src/pages/[...lang]/contact.astro` and
`src/pages/[...lang]/apply/[program].astro`.

---

## Adding a new language

The template ships with English (`/`) and Spanish (`/es/`). Every page lives
once in `src/pages/[...lang]/` and renders for each locale returned by
`localeStaticPaths()`, so there is no page tree to mirror. To add another
language (e.g. French):

1. Add `fr: 'fr-FR'` to `LOCALES` in `astro.config.mjs`
2. In `src/i18n/utils.ts`: add `'fr'` to the `Locale` type and `locales`
   array, add a `fr` entry to `localeMeta` (native label + og:locale), and
   register `fr.json` in the `translations` map
   (create `src/i18n/fr.json` by copying `en.json` and translating)
3. Add a `fr` entry to each page's `copy` object in
   `src/pages/[...lang]/*.astro` — TypeScript will point you at every one
4. Translate the content collections (see below)

That's it — the header's language selector, hreflang tags, and og:locale
meta tags all read from `locales`/`localeMeta`, so they update automatically
(the header even switches from a simple toggle link to the USWDS dropdown
once there are 3+ locales).

### Translating content

Collection entries are translated by adding a **locale subdirectory** beside
the default-locale files, so translators edit real Markdown instead of strings
crammed into frontmatter:

```
src/content/services/snap.mdx        # English (default locale)
src/content/services/es/snap.mdx     # Spanish
src/content/services/fr/snap.mdx     # French
```

Both files describe the same service, share the URL slug `snap`, and translate
everything — `title`, `summary`, `eligibility`, `keyFacts`, and the body prose.
Keep `applySlug`, `order`, and `related` identical across a set, since those are
identifiers rather than copy.

**Translations are optional.** A page renders the requested locale's file when
one exists and falls back to the default locale otherwise, so a partial
translation ships fine and a missing file never breaks the build. The lookup
lives in `entriesForLocale()` in `src/utils/content.ts`.

The plain-language gate scores each file with a formula built for the language
it is written in — Flesch-Kincaid for English, Fórmula de Crawford for Spanish —
because running an English readability formula over Spanish would fail plain
translations for having longer words. Add a formula there when you add a
language, or its files will be scored as English.
