Fork it, trim what you don't need.\n\n```bash\nvt new my-app # clones this template → vals/my-app\ncd vals/my-app\nvt watch # live-push changes on save\n```\n\n---\n\n## Files\n\n| File | Trigger | Purpose |\n|---|---|---|\n| `index.http.ts` | HTTP | Web server — routes, JSON API, HTML pages |\n| `cron.ts` | Cron | Two tasks: pulse every 5 min + maintenance every 24h |\n| `email.ts` | Email | Receive inbound email + send outbound |\n| `db.ts` | — | SQLite schema & query helpers |\n| `storage.ts` | — | Blob storage read/write/list/delete |\n| `shared.ts` | — | Constants, types, `html()`, `env()`, `parseDuration()` |\n\n**Rule:** One concern per file. Every file except `shared.ts` is independently deletable.\n\n---\n\n## HTTP Routes (`index.http.ts`)\n\n> **Why `.http.ts`?** The `vt` CLI auto-detects any file with `http` in the\n> name as an HTTP trigger and registers it on Val Town automatically when pushed.\n\n| Route | Method | Description |\n|---|---|---|\n| `/` | GET | HTML landing page with visit counter |\n| `/api/health` | GET | JSON health check |\n| `/api/visits` | GET | Recent visits from SQLite |\n| `/api/echo` | POST | Echo back your JSON body |\n| `/*` | ANY | 404 JSON response |\n\nYour val is live at `https://--.web.val.run`. Supports any framework (Hono, itty-router) or plain `Request → Response`.\n\n

Route implementation pattern

\n\n```ts\nexport default async function handler(req: Request): Promise {\n const { pathname } = new URL(req.url);\n\n if (pathname === \"/api/hello\") {\n return Response.json({ message: \"Hello!\" });\n }\n\n return Response.json({ error: \"Not found\" }, { status: 404 });\n}\n```\n

\n\n---\n\n## Cron (`cron.ts`)\n\nOne trigger, two tasks — each with its own env-configurable interval.\n\n**Setup:** Editor → **+** → **CRON** → point at `cron.ts` → schedule: `every 5 minutes`\n\n| Task | Env var | Default | Purpose |\n|---|---|---|---|\n| Pulse | `CRON_PULSE_INTERVAL` | `\"5m\"` | Polling, health-checks, work-queues |\n| Maintenance | `CRON_MAINTENANCE_INTERVAL` | `\"1d\"` | Pruning, archiving, digests |\n\nBoth env vars accept the same duration format, and independently gate their work via a last-run timestamp stored in `template_meta` (SQLite):\n\n```\n\"30s\" → 30 seconds\n\"5m\" → 5 minutes\n\"2h\" → 2 hours\n\"1d\" → 1 day\n\"DISABLED\" → skip entirely (no UI changes needed)\n```\n\n- Min platform interval: **15 min** (free) / **1 min** (Pro) — always UTC\n- `parseDuration()` in `shared.ts` handles parsing\n\n---\n\n## Email (`email.ts`)\n\n### Receiving\n\nYour val gets an address: `.@valtown.email`\n\n**Setup:** Editor → **+** → **EMAIL** → point at `emailHandler`\n\nHandler receives an `InboundEmail` with `from`, `to`, `subject`, `text`, `html`, `attachments` (standard `File[]`), and `headers`.\n\n### Sending\n\n```ts\nimport { sendNotification, sendWithAttachment } from \"./email.ts\";\n\n// Simple text email (sends to yourself on free, anyone on Pro)\nawait sendNotification(\"Subject\", \"Body text\");\n\n// With attachment\nawait sendWithAttachment(\"Report\", \"See attached\", {\n content: btoa(\"CSV,data\"),\n filename: \"report.csv\",\n type: \"text/csv\",\n});\n```\n\n| Feature | Free | Pro |\n|---|---|---|\n| Send to self | ✅ | ✅ |\n| Send to others | ❌ | ✅ |\n| CC / BCC | ❌ | ✅ |\n| Rate limit | 100/min | 100/min |\n\n

Full email options (Pro)

\n\n```ts\nimport { email } from \"@std/email\";\n\nawait email({\n to: \"user@example.com\",\n subject: \"Hello\",\n text: \"Plain text body\",\n html: \"

Rich HTML body

\",\n cc: \"cc@example.com\",\n attachments: [{\n content: btoa(\"file contents\"),\n filename: \"doc.txt\",\n type: \"text/plain\",\n }],\n});\n```\n

\n\n---\n\n## SQLite (`db.ts`)\n\nEvery account gets a private SQLite database (Turso). Shared across all vals — **namespace your tables**.\n\n```ts\nimport { sqlite } from \"@std/sqlite\";\n\n// Simple query\nconst { rows } = await sqlite.execute(\"SELECT 1\");\n\n// Parameterized\nawait sqlite.execute({ sql: \"SELECT * FROM users WHERE age > ?\", args: [18] });\n\n// Batch (transaction)\nawait sqlite.batch([\n \"CREATE TABLE IF NOT EXISTS t (id INTEGER PRIMARY KEY)\",\n { sql: \"INSERT INTO t VALUES (?)\", args: [1] },\n]);\n```\n\n- Returns `{ rows: any[][], columns: string[] }` — rows are arrays, not objects\n- Use `CREATE TABLE IF NOT EXISTS` for migrations (safe to re-run)\n- Storage: **10 MB** (free) / **1 GB** (Pro)\n\n

\n\n---\n\n## Blob Storage (`storage.ts`)\n\nFor binary data, JSON snapshots, config — anything that doesn't fit in SQLite.\n\n```ts\nimport { saveJSON, loadJSON, listKeys, remove } from \"./storage.ts\";\n\nawait saveJSON(\"config\", { theme: \"dark\" });\nconst cfg = await loadJSON<{ theme: string }>(\"config\");\n```\n\nRaw API: `blob.set(key, value)`, `blob.get(key)`, `blob.list(prefix?)`, `blob.delete(key)`.\n\nKeys are prefixed with `template/` — change the `PREFIX` constant when you rename your val.\n\n

\n\n---\n\n## Imports\n\n**Inline URLs only** — never use `deno.json` import maps for Val Town deps.\nVal Town's runtime resolves raw URLs natively; import maps break at deploy time.\n\n```ts\n// ✅ Correct — inline URLs everywhere\nimport { sqlite } from \"https://esm.town/v/std/sqlite/main.ts\";\nimport { blob } from \"https://esm.town/v/std/blob\";\nimport { email } from \"https://esm.town/v/std/email\";\nimport { Hono } from \"npm:hono\";\nimport { z } from \"jsr:@std/zod\";\n\n// ✅ Relative imports within the val\nimport { APP_NAME } from \"./backend/shared.ts\";\n\n// ❌ Never — import maps in deno.json for external deps\n// import { sqlite } from \"@std/sqlite\";\n```\n\nAll Deno import styles work: `./relative.ts`, `npm:lodash`, `jsr:@std/zod`,\n`https://esm.sh/hono`, `https://esm.town/v/user/val`.\n\n---\n\n## Environment Variables\n\nSet in Val Town UI sidebar → **Environment Variables**. Private even on public vals.\n\n```ts\nconst key = Deno.env.get(\"MY_API_KEY\"); // Deno-native\nconst key = env(\"MY_API_KEY\", \"fallback\"); // from shared.ts\n```\n\n`Deno.env.set()` is a **no-op** on Val Town.\n\n---\n\n## `val.yml` Configuration\n\n```yaml\nname: \"_template\" # Val name on Val Town\npublic: true # true = public, false = private/unlisted\norg: \"uapps\" # Deploy under this org (optional)\n```\n\n---\n\n## Runtime & Limits\n\n| | Detail |\n|---|---|\n| Runtime | Deno (latest stable), TypeScript built-in |\n| Timeout | ~30s per request |\n| Filesystem | ❌ — use SQLite + Blob |\n| WebSockets | ❌ |\n| Web APIs | ✅ Request, Response, fetch, URL, Headers |\n\n| Resource | Free | Pro |\n|---|---|---|\n| Private vals | 5 | Unlimited |\n| SQLite | 10 MB | 1 GB |\n| Cron min interval | 15 min | 1 min |\n| Email | Self only | Anyone |\n\n---\n\n## CLI Workflow\n\n```bash\nvt status # Check sync state\nvt push # Deploy local → Val Town\nvt pull # Pull remote → local\nvt watch # Auto-push on file save\nvt checkout -b feat # Work on a branch\nvt log # View version history\n```\n","# Val Town Template\n\nStarter val with HTTP, Cron, Email, SQLite, and Blob.

Create a new val from this template**\n\n```bash\ncd /path/to/uApps\nvt new my-app\ncd vals/my-app\n```\n\n**2. Push it to Val Town**\n\n```bash\nvt push\n# or: vt watch (auto-push on save)\n```\n\n> **Important:** `vt push` auto-detects triggers from filenames (e.g.,\n> `index.http.ts` → HTTP, `cron.ts` → Cron, `email.ts` → Email). If triggers\n> don't appear on the Val Town platform after pushing, manually add them via the\n> `+` button in the val editor. Then point each trigger at its file.\n\n**3. Open it in your browser**\n\n```bash\nvt url # prints your live URL\n```\n\nVisit the URL → you should see the starter page with a visit counter.\n\n**4. Try the API**\n\n```\nGET /api/health → JSON health check\nGET /api/visits → visit history from SQLite\nPOST /api/echo → echoes your JSON body back\n```\n\n---\n\n## HTTP Trigger (`index.http.ts`)\n\n```mermaid\nsequenceDiagram\n actor User\n participant HTTP as index.http.ts\n participant Frontend as frontend/\n participant DB as backend/db.ts\n\n User->>HTTP: GET /\n HTTP->>DB: recordVisit(\"/\")\n HTTP->>Frontend: serveFile(\"/frontend/index.html\")\n Frontend-->>User: HTML + visit counter\n\n User->>HTTP: GET /api/visits\n HTTP->>DB: getRecentVisits(20)\n HTTP->>DB: getVisitCount()\n DB-->>HTTP: rows\n HTTP-->>User: { total, visits }\n\n User->>HTTP: POST /api/echo\n HTTP-->>User: { echo: body, receivedAt }\n```\n\nRoute dispatch via `if/else` path matching — no framework needed:\n\n| Route | Method | What it does |\n|-------|--------|-------------|\n| `/` | GET | Serves `frontend/index.html`, records visit |\n| `/frontend/*` | GET | Serves static files from `frontend/` |\n| `/api/health` | GET | JSON health check |\n| `/api/visits` | GET | Recent visits + total count from SQLite |\n| `/api/echo` | POST | Echoes request body back |\n| `*` | any | 404 JSON |\n\n---\n\n## Cron Trigger (`cron.ts`)\n\n```mermaid\nflowchart LR\n subgraph CRON[\"cron.ts — runs every 5 min\"]\n direction TB\n ENTRY[\"export default()\"] --> PULSE[\"pulse()\"]\n ENTRY --> MAINT[\"maintenance()\"]\n\n PULSE -->|\"shouldRun()\"| P_GATE{\"Interval elapsed?\"}\n P_GATE -->|\"yes\"| P_WORK[\"⚡ Pulse task

(prune old visits)\"]\n M_GATE -->|\"no\"| M_SKIP[\"skip\"]\n end\n\n P_WORK --> DB[(SQLite)]\n M_WORK --> DB\n```\n\nTwo independent tasks, one trigger. Each gates itself via `shouldRun()` which\nstores last-run timestamps in SQLite.\n\n| Task | Default interval | Env var to control |\n|------|-----------------|--------------------|\n| Pulse | Every 5 min | `CRON_PULSE_INTERVAL` (`\"5m\"`, `\"1h\"`, `\"DISABLED\"`) |\n| Maintenance | Every 1 day | `CRON_MAINTENANCE_INTERVAL` (`\"1d\"`, `\"6h\"`, `\"DISABLED\"`) |\n\n---\n\n## Email Trigger (`email.ts`)\n\n```mermaid\nflowchart TB\n INBOUND[\"📧 Inbound email
.@valtown.email\"] --> HANDLER[\"emailHandler()\"]\n HANDLER --> LOG[\"log subject + body\"]\n HANDLER --> ATTACH[\"process attachments\"]\n\n subgraph OUTBOUND[\"Outbound helpers\"]\n NOTIFY[\"sendNotification()\"]\n ATTACH_SEND[\"sendWithAttachment()\"]\n end\n\n HANDLER -.->|\"optional: reply\"| NOTIFY\n ATTACH --> BLOB[(\"Blob Store\")]\n```\n\nTwo parts in one file:\n\n**Inbound** — `export default async function emailHandler(inbound)` handles\nincoming mail. Logs subject/body, saves attachments to Blob.\n\n**Outbound** — exported helper functions for sending email programmatically:\n- `sendNotification(subject, body, opts?)` — plain text email\n- `sendWithAttachment(subject, body, attachment)` — with base64 attachment\n\n> **Free plan:** outbound sends to yourself only. **Pro:** send to anyone.\n\n---\n\n## SQLite (`backend/db.ts`)\n\n```mermaid\nerDiagram\n VISITS {\n int id PK\n text page\n timestamp created_at\n }\n META {\n text key PK\n text value\n }\n```\n\nTwo tables, auto-migrated on first use:\n\n| Table | Purpose |\n|-------|---------|\n| `visits` | Page visit log — each HTTP request to `/` inserts a row |\n| `meta` | Key-value store — cron uses it for `last_run` timestamps |\n\nKey functions:\n- `recordVisit(page)` — insert a visit\n- `getRecentVisits(limit)` — latest N visits\n- `getVisitCount()` — total rows in `visits`\n- `getMetaValue(key)` / `setMetaValue(key, value)` — KV read/write\n- `pruneOldVisits(days)` — delete visits older than N days\n\n**Gotcha:** SQLite is per-val. Use the `/main.ts` import path (val-scoped), not\n`/dummy.ts` (shared).\n\n---\n\n## Blob Storage (`backend/storage.ts`)\n\n```mermaid\nflowchart LR\n subgraph BLOB[\"Account-scoped Blob (Cloudflare R2)\"]\n direction TB\n SET[\"blob.set(key, value)\"]\n GET[\"blob.get(key)\"]\n LIST[\"blob.list()\"]\n DEL[\"blob.delete(key)\"]\n end\n\n APP[\"any val in account\"] --> SET\n APP --> GET\n APP --> LIST\n APP --> DEL\n```\n\nShared across **all vals** in your account. Good for cross-val state, config,\nfile uploads.\n\nKey functions:\n- `saveJSON(key, data)` / `getJSON(key)` — typed JSON storage\n- `saveText(key, text)` — plain text\n- `listBlobs()` — all keys\n- `deleteBlob(key)` — remove\n\n> **Warning:** Blob is account-scoped. Key collisions across vals are possible\n> — use namespaced keys like `emails/`, `config/`, etc.\n\n---\n\n## Shared (`backend/shared.ts`)\n\nLayer 0 — every other file depends on this. Zero dependencies itself.\n\n| Export | Purpose |\n|--------|---------|\n| `APP_NAME` | App name constant (change this to rename your app) |\n| `Email` type | Inbound email shape (`from`, `to`, `subject`, `text`, `html`, `attachments`) |\n| `env(key, fallback)` | Read env vars with a default fallback |\n| `parseDuration(raw)` | Parse `\"5m\"`, `\"1h\"`, `\"1d\"` → milliseconds |\n\n---\n\n## Layering\n\n```mermaid\ngraph BT\n subgraph \"Layer 2 — Triggers\"\n HTTP[\"index.http.ts\"]\n CRON[\"cron.ts\"]\n EMAIL[\"email.ts\"]\n end\n\n subgraph \"Layer 1 — Backend\"\n DB[\"backend/db.ts\"]\n BLOB[\"backend/storage.ts\"]\n end\n\n subgraph \"Layer 0 — Foundation\"\n SHARED[\"backend/shared.ts\"]\n end\n\n HTTP --> DB\n HTTP --> BLOB\n HTTP --> SHARED\n CRON --> DB\n CRON --> BLOB\n CRON --> SHARED\n EMAIL --> BLOB\n EMAIL --> SHARED\n DB --> SHARED\n```\n\nEvery file depends only on lower layers.
