Local development

cd apps/web
pnpm install
pnpm exec wrangler d1 migrations apply pm-daily --local   # one-time
pnpm dev                                                  # starts at :5173
curl -X POST http://localhost:5173/api/_dev/seed          # seeds today's content

Then open http://localhost:5173/. Sign-in flows require GOOGLE_CLIENT_ID/GOOGLE_CLIENT_SECRET and RESEND_API_KEY in apps/web/.dev.vars — see .env.example.

Cloudflare resource IDs (for forks)

The committed apps/web/wrangler.toml references account-scoped resource IDs from the original deployment. Forks should run:

wrangler d1 create pm-daily               # → copy database_id
wrangler kv namespace create pm-daily-kv  # → copy id
wrangler vectorize create lennys_metadata --dimensions=1024 --metric=cosine

…and replace the IDs in wrangler.toml accordingly.

Deploy

cd apps/web
pnpm build && pnpm exec wrangler deploy

Worker secrets (set via wrangler secret put): BETTER_AUTH_SECRET, BETTER_AUTH_URL, GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, RESEND_API_KEY.
