~val.town

\n\nBackend without the backend\n\nNote:\nHold this for ~5 seconds while people settle. Don't read it.\n\n---\n\n# What is val.town?\n\n- TypeScript on Deno, multi-file projects\n- A public HTTPS URL on every save\n- Built-in: SQLite (Turso), blob storage, cron, email, logs, env vars\n- Branches, version history, and PRs baked in\n- No CI, no deploy step, no infra\n\nNote:\nIt's a serverless platform — but the relevant claim isn't *that* it's serverless,\nit's *how much* comes for free. Most platforms give you the compute and leave you\nto bring everything else. Val.town hands you a runtime, a database, a key-value\nstore, a scheduler, and a public URL — without provisioning anything.\n\n---\n\n# A new spot in the stack\n\n

\nLaptop script ←———— val.town ————→ Production service\n

\n\n\nMocks · Webhook sinks · Integration PoCs · Scheduled jobs · Internal tools · Production glue\n\n\nNote:\nWe have two well-defined tiers: one-off scripts on someone's laptop, and proper\nservices in the platform. There's a whole middle ground where things deserve a\npublic URL and a database but don't deserve a Rails app — and that's been\nawkward for us.\n\nVal.town is exactly that tier. The examples on screen are the kinds of things\nI've been reaching for it for.\n\n---\n\n# What changes\n\n- **Speed** — edit to live in seconds\n- **Shareable** — not localhost; you can hand a partner the URL today\n- **Try ideas** — without touching the main codebase\n\nNote:\nI want to land three claims before I show you anything. Each of these will be\nvisible in the demo — pay attention to which ones land for you and which ones\ndon't.\n\n---\n\n# Pairs with agents\n\n- Read and edit any file in your val\n- Query the SQLite DB directly\n- Tail logs to debug a recent run\n- Run an endpoint to verify a change\n- Create branches, open PRs\n\nNote:\nThis is the operator-level access you'll see in the demo. When I ask Claude\nto polish the poll later, it's reading my code, generating a diff, writing\nthe file back, and saving. Same iteration loop as me typing — just driven\nby a prompt.\n\nYou can trigger this from Claude Code, claude.ai, Cursor — anywhere with\nMCP support.\n\nThis is your \"one more thing\" before the demo — set up the polish-via-Claude\nmoment as the live demonstration of what's on this slide.\n\n---\n\n

Let me show you.

\n\nNote:\nTransition into the cold hook. Don't linger.\n\nDemo order:\n 1. Paste BLOCK 1 (basic poll) → save → open URL → vote yourself once or twice\n 2. \"OK, that's functional. Let me make it look like I meant it.\"\n 3. Paste BLOCK 2 (polished poll) → save → refresh (data persists, layout changes)\n 4. Ask Claude via MCP to polish further → watch it edit live\n 5. Share URL / QR code → audience votes from phones → refresh → bars move\n\n---\n\n

\n\nBuilt entirely on val.town\n\nNote:\nThe pivot. You've seen the poll — ~30 lines of code, audience-participation\napp in 90 seconds. Now let me show you what the same iteration loop looks\nlike applied to something with real integration stakes. Two weeks of\nHubSpot work — OAuth install, custom workflow actions, a UI Extension\ncard — all on val.town. None of it in our main codebase.\n\n---\n\n# Public REST API\n\n

\n\nBearer session token\n\n- \\`GET /campaigns\\` — list campaigns with embedded gifts\n- \\`GET /gifts\\` — list gift catalogue\n- \\`POST /gift_requests\\` — create gift request\n- \\`GET /gift_requests?recipient_email=…\\` — gift history\n\n

\n\nNote:\nThe andopen v2026-05 stand-in. Bearer-authed, andopen-shaped responses,\nzero HubSpot vocabulary on the wire. The CRM card calls these endpoints\nto list campaigns and create gifts; the workflow action also delegates\nto these internally after the HubSpot adapter translates the request.\n\n---\n\n# OAuth + UI Extension bootstrap\n\n

\n\nApp install\n\n- \\`GET /admin/hubspot/install\\` — start install\n- \\`GET /admin/hubspot/oauth_callback\\` — OAuth callback\n\nUser session\n\n- \\`POST /admin/hubspot/connections/:portal/session\\` — UI Extension session mint (HMAC)\n\n

\n\nNote:\nInstall, OAuth callback, and the UI Extension session bootstrap. The\nbootstrap endpoint is HMAC-verified and is the bridge between HubSpot's\nHMAC-signed runtime and our Bearer-authed public API — it mints a\nsession token bound to (tenant, user) that the card uses as its Bearer\nfor everything else.\n\n(Three debug routes also exist — list connections, force-refresh,\nsimulate-uninstall — omitted here for brevity. Available in the val if\nasked.)\n\n---\n\n# HubSpot adapter\n\n

\n\nHMAC-verified\n\n- \\`POST /integrations/hubspot/workflow_actions/options\\` — workflow action dropdown\n- \\`POST /integrations/hubspot/workflow_actions/execute\\` — workflow action firing\n- \\`POST /integrations/hubspot/webhooks\\` — HubSpot webhook receiver\n\n

\n\nNote:\nHubSpot's protocol-specific surface. Dedicated endpoints because workflow\naction URLs can't carry a Bearer token — they only receive HMAC-signed\nrequests. Translates HubSpot's request shape to andopen domain operations\nand delegates to existing services. Three endpoints: workflow action\noptions (campaign dropdown), workflow action execute (the firing), and\nthe webhook receiver (currently handles \\`app.uninstalled\\`).\n`;\n\nexport default async (_req: Request) => {\n return new Response(\n `\n\n\n \n \n val.town\n \n \n \n \n\n\n
