Waymark

Mobile-first travel itinerary app built on Astro v6 + Cloudflare Workers. Itineraries are gated by a PIN, stored in Cloudflare KV, and accessible via a machine-to-machine admin API for AI agents.

Stack

• Astro v6 — SSR on Cloudflare Workers
• Cloudflare KV — one JSON document per trip
• Tailwind CSS v4 — mobile-first styling
• Zod — schema validation
• Web Crypto API — PBKDF2 PIN hashing, HMAC-SHA256 cookie signing

Setup

bun install

This is a Bun monorepo with workspaces:

• apps/web — Astro app (main itinerary site)
• packages/shared — shared types and utilities
• packages/mcp-server — MCP server for agent access

All commands below should be run from apps/web/ unless noted.

Required Bindings & Secrets

Local Dev

1. Create a .dev.vars file in the project root:

ADMIN_API_TOKEN=dev-admin-token-change-in-prod
COOKIE_SIGNING_SECRET=dev-cookie-secret-32-chars-minimum

1. Create KV namespaces (one-time setup):

wrangler kv namespace create TRIPS
wrangler kv namespace create TRIPS --preview

Update wrangler.jsonc with the returned IDs.

1. Start the dev server:

bun run dev

The app runs at http://localhost:4321.

Seeding Sample Data

The sample trip has ID a8k3m2q9 and PIN 1234.

cd apps/web

# 1. Generate the seed JSON
bun scripts/seed.ts > /tmp/trip.json

# 2. Seed into local KV (--preview targets the namespace the dev server uses)
wrangler kv key put --binding=TRIPS --local --preview "trip:a8k3m2q9" --path /tmp/trip.json

# 3. Visit the trip
open http://localhost:4321/trip/a8k3m2q9
# Enter PIN: 1234

To generate a PIN hash for a new trip:

cd apps/web
bun scripts/hash-pin.ts <pin> <salt>
# Example: bun scripts/hash-pin.ts mysecretpin abc123salt456

Build & Deploy

# Build (from root)
bun run build

# Deploy to Cloudflare Workers (from root, runs: bun run --filter @waymark/web deploy)
bun run deploy

# Or manually from apps/web:
cd apps/web
wrangler deploy

# Set secrets (from apps/web, one-time)
cd apps/web
wrangler secret put ADMIN_API_TOKEN
wrangler secret put COOKIE_SIGNING_SECRET

Admin API

All admin endpoints require Authorization: Bearer <ADMIN_API_TOKEN>.

GET trip

curl -H "Authorization: Bearer $ADMIN_API_TOKEN" \
  https://waymark.<subdomain>.workers.dev/api/admin/trips/a8k3m2q9

Returns the full itinerary JSON document.

Upsert trip

curl -X POST \
  -H "Authorization: Bearer $ADMIN_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d @/tmp/trip.json \
  https://waymark.<subdomain>.workers.dev/api/admin/trips/upsert

Returns: { "ok": true, "id": "a8k3m2q9", "updatedAt": "..." }

Delete trip

curl -X POST \
  -H "Authorization: Bearer $ADMIN_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"id":"a8k3m2q9"}' \
  https://waymark.<subdomain>.workers.dev/api/admin/trips/delete

Returns: { "ok": true, "deleted": true }

Traveler Access

Verify PIN

curl -X POST \
  -H "Content-Type: application/json" \
  -d '{"id":"a8k3m2q9","pin":"1234"}' \
  https://waymark.<subdomain>.workers.dev/api/trip-access/verify

Returns: { "ok": true } with a Set-Cookie header on success, or { "error": "Invalid PIN" } on failure.

Data Model

One KV document per trip, stored under trip:{id}.

The full schema is defined in src/types/itinerary.ts. Key fields:

• id — 8-character alphanumeric slug (e.g. a8k3m2q9)
• stays[] — hotel stays with explicit checkinDate/checkoutDate; check-in/checkout timeline entries are generated from this at render time
• days[] — array of day objects, each with items[]
• items[].type — transport | activity | note | restaurant | transfer (do not store hotel items — use stays[])
• items[].status — booked | quoted | pending | canceled
• pinSalt + pinHash — PBKDF2-SHA256 PIN verification (never expose to clients)

Security Notes

• PIN hashes use PBKDF2-SHA256 with 100,000 iterations and a random salt
• Access cookies are HMAC-SHA256 signed, HttpOnly, Secure, SameSite=Lax, expire after 7 days
• Admin token comparisons use constant-time XOR to prevent timing attacks
• Trip URLs contain no personal information
• Admin token is never rendered in public HTML

Agent Skill

This repo includes a waymark-trips skill for Claude Code and OpenClaw agents, enabling them to create, read, update, and delete trips via the admin API.

Install it with the skills CLI:

# Project-scoped (current directory)
npx skills add aydrian/waymark

# Global (available in every session)
npx skills add aydrian/waymark -g

Once installed, an agent can manage trips on https://waymark.itsaydrian.com with just your WAYMARK_ADMIN_TOKEN. See waymark-trips/SKILL.md for full details.
