Concrete Factory — Local demo

This repository contains a small static site (/site) for a demo concrete factory website and a minimal Node.js server (/server) that serves the site and accepts orders via POST /api/order.

This README explains how to run the project locally, how the server handles orders, and how to enable SMTP email sending.

Project layout

• site/ — static frontend (HTML, CSS, JS). Open at / when server runs.
• server/ — minimal Express server that serves site/ and accepts /api/order requests.
• server/server.js — server entrypoint.
• server/package.json — server dependencies and start script.
• server/.env — optional (not checked into repo) SMTP and runtime settings.
• prices.json — example prices (exported from admin panel)

Quick start (development)

1. Install server dependencies:

cd /Users/pro/Downloads/concrete_factory/server
npm install

2. Create and edit server/.env (copy from provided example if present). Example contents:

# server/.env
SMTP_HOST=smtp.example.com
SMTP_PORT=587
SMTP_SECURE=false
SMTP_USER=your_smtp_user@example.com
SMTP_PASS=your_smtp_password
TO_EMAIL=sales@example.com
FROM_NAME="Бетонный завод"
PORT=3000

Notes:

• SMTP_HOST is required to enable email sending. If missing, the server will still accept orders and save them to server/orders.json, but it will not attempt to send email.
• For port 465 set SMTP_SECURE=true. For ports like 587 use SMTP_SECURE=false (STARTTLS).

3. Run the server:

node server/server.js

4. Open the site in your browser (do not open files with file://):

http://localhost:3000/

How the order flow works

• The frontend makes a POST to /api/order with JSON: { markdown: string, order: { ... } }.
• The server appends the order (with timestamp) to server/orders.json.
• If SMTP is configured (SMTP_HOST + TO_EMAIL), the server attempts to send an email to TO_EMAIL with the order contents. The server logs success or failure to the console.

Troubleshooting: email not delivered

1. Ensure server/.env is at server/.env (the server reads this exact path).
2. Restart the server after changing .env.
3. Check server logs when sending an order — logs show Order received: and either Order email sent to ... or Failed to send order ... with the underlying error.
4. Verify SMTP credentials and port. Common combos:
   • Port 465 + SMTP_SECURE=true
   • Port 587 + SMTP_SECURE=false (STARTTLS)
5. Check the recipient mailbox (Inbox + Spam). Some providers may reject or place messages into Spam if SPF/DKIM/DMARC aren't configured for the sending domain.
6. If you use Gmail or Yandex, ensure your account allows SMTP sending for third-party apps (app password or less-secure-apps setting as applicable).

If you want the API to return explicit failures when email sending fails (instead of saving order and returning OK), open an issue or request and I can switch the endpoint to respond with an error status when mail sending fails.

Developer notes

• The frontend code (site/js/main.js) originally used fetch('/api/order'), which fails when the page is opened via file://. Always serve the site over HTTP to avoid CORS and local resource restrictions.
• Orders saved locally are stored in server/orders.json.

Useful commands

• Install deps: cd server && npm install
• Run server: node server/server.js
• Send a test order from the command line:

curl -X POST http://localhost:3000/api/order \
	-H "Content-Type: application/json" \
	-d '{"markdown":"test order","order":{"buyerName":"Test","buyerPhone":"000","buyerEmail":"test@example.com","details":[],"materialTotal":0,"delivery":0,"total":0}}'

Want me to improve this repo?

• I can add explicit SMTP verification at startup, return mail-sending errors to the frontend, or wire a simple admin page to view server/orders.json.

If you'd like any of the above, tell me which change to make and I'll apply it.
