Invoicer

Create, preview, download, and email professional invoices in seconds. Cloudflare Pages (static UI) + Pages Functions (API) + D1 (database), with server-side email via Resend.

Status

Phase	State
Core generator (form → live preview → PDF)	✅ done
D1 schema + API (save/list invoices & clients)	🔜
Magic-link auth (passwordless, via Resend)	🔜
Email invoice to client (server-side Resend)	🔜
Deploy to Cloudflare (invoices.aswincloud.com)	⛔ needs CF auth

Run locally

No backend needed for the core generator:

# any static server works
python3 -m http.server 8099 --directory public
# open http://127.0.0.1:8099

Or with the Cloudflare toolchain (once D1 is added):

npm install
npm run dev            # wrangler pages dev

Features (core, shipping now)

• Form with live preview — every keystroke re-renders the invoice.
• Dynamic line items — add/remove rows, auto qty × rate.
• Tax modes — CGST+SGST split, single tax (IGST/VAT), or none.
• Discount, multi-currency (₹ uses Indian digit grouping), status badge.
• Business profile persists in localStorage — enter it once.
• Download PDF via the browser print engine (client-side, offline-capable).

Architecture

public/            static site (Pages)
  index.html       form + preview shell
  styles.css       screen + @media print styles
  app.js           render, totals, persistence, print
functions/api/     Pages Functions (D1-backed API) — WIP
migrations/        D1 SQL migrations — WIP

Deploy (later)

Requires Cloudflare auth (wrangler login or CLOUDFLARE_API_TOKEN):

wrangler d1 create invoicer-db          # paste id into wrangler.toml
npm run db:migrate:remote
wrangler pages secret put RESEND_API_KEY
npm run deploy

Notes

• Secrets (RESEND_API_KEY) live server-side only (Pages secret) — never in the browser.
• Resend requires a User-Agent header on API calls, or it returns 403 / 1010.
