Applicants apply either as a **Standard Applicant**\nor a **Housing Voucher / Section 8 Applicant**, pay the **$35.00 application\nfee** online through Stripe, and the portal emails notifications to your team.\n\n👉 **Try it live:** [https://rental-application.val.run](https://rental-application.val.run)\n\n## Features\n\n- **Application-type toggle** — selecting *Section 8* reveals Housing\n Authority, voucher amount, approved bedroom count, and caseworker contact\n fields (and hides them again for Standard applicants).\n- **Six form sections**: Property Info · Applicant Personal Details ·\n Rental History · Financial Details · Disclosures & Accessibility ·\n Application Fee & Authorization.\n- **Online payment** — after submitting, the applicant is offered a secure\n **\"Pay $35.00 Now\"** button that opens a Stripe Checkout page. A completed\n payment is verified via Stripe webhook and the application is marked paid.\n- **Email notifications** — your team gets an email when an application is\n submitted and again when the fee is paid; applicants get a confirmation.\n- **Executive palette** — Navy `#1a365d`, Slate `#4a5568`, soft accent `#ebf8ff`.\n- **Accessibility (WCAG)** — real `` pairs, `aria-invalid`,\n `role=\"alert\"` validation, visible focus rings, keyboard-friendly controls,\n fully mobile responsive.\n- **Validation** — required-field checks, email/phone/SSN masking (last-4-only\n display), conditional validation, digital-signature requirement.\n- **Persistence** — applications + payment status stored in the val's SQLite DB.\n\n## Architecture\n\n```mermaid\ngraph LR\n Browser -->|\"GET /\"| Hono[\"index.ts

Create a Stripe account (or connect to an existing one), then grab the API\n secret key — Restrict API key access: \n2. Add the two Stripe variables and then register the webhook so Stripe can\n confirm payments:\n - Endpoint: `https://rental-application.val.run/api/stripe-webhook`\n - Subscribe to the **`checkout.session.completed`** event.\n - After saving, copy the `whsec_…` signing secret into `STRIPE_WEBHOOK_SECRET`.\n\n 👉 Add STRIPE_SECRET_KEY here: https://www.val.town/x/affordableapartmentsusa/rental-application-portal/environment-variables?key=STRIPE_SECRET_KEY\n 👉 Add STRIPE_WEBHOOK_SECRET here: https://www.val.town/x/affordableapartmentsusa/rental-application-portal/environment-variables?key=STRIPE_WEBHOOK_SECRET\n\n For testing, use Stripe test keys (`sk_test_…`) and their test card\n `4242 4242 4242 4242`. Switch to live keys when you're ready to collect\n real payments.\n\n### Notifications & the free-tier caveat\n\nNotifications are sent through Val Town's built-in `std/email`. **The Free\nplan only allows sending email to the account owner's own address** — external\nrecipients (Cynthia's inbox or applicants' inboxes) require the **Pro** or\n**Business** plan. If you stay on Free, submissions and payments still work;\nthe notification sends are attempted, logged, and safely ignored on failure.\nEmails are always wrapped so a delivery problem never breaks the application\nflow.\n\n## API\n\n| Method | Route | Description |\n| --- | --- | --- |\n| `GET` | `/` | The application portal UI |\n| `POST` | `/api/application` | Store an application (`ApplicationFormData` JSON) |\n| `GET` | `/api/application/:id` | Fetch a single application (used on the paid confirmation page) |\n| `POST` | `/api/checkout/:id` | Create a Stripe Checkout session for the `$35` fee |\n| `POST` | `/api/stripe-webhook` | Stripe webhook — marks an application paid & emails notifications |\n| `GET` | `/api/applications` | List the 50 most recent applications (internal) |\n\n## Running it\n\nThe val is deployed automatically on save.

Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1. Create `frontend/root.tsx`:\n\n```tsx\n/** @jsxImportSource npm:hono@4/jsx */\nimport { raw } from \"npm:hono@4/html\";\nimport { immutableFileUrl } from \"https://esm.town/v/std/utils/index.ts\";\n\n// The HTML shell for the app. It is never cached, so immutableFileUrl can stamp\n// the current val version into each asset URL — the browser caches those\n// immutably, and publishing the val changes the URLs, refetching exactly once.\nexport function Root() {\n return (\n <>\n {raw(\"<!DOCTYPE html>\")}\n <html lang=\"en\">\n <head>\n <meta charSet=\"UTF-8\" />\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" />\n <title>React Hono Val Town Starter\n
