Landing page + admin + API built with Node.js (server.js) and static HTML/CSS/JS.

• Node.js HTTP server (CommonJS)
• SQLite (brain.db) by default via node:sqlite
• Optional Postgres (DATABASE_URL) via @neondatabase/serverless
• Email sending via Resend REST API

1. Copy sample env:
   • cp .env.example .env
2. Install deps:
   • npm install
3. Build admin assets:
   • npm run build
4. Run server:
   • node server.js

Default URL: http://localhost:3000

1. Prepare server
   • Install Node.js >=22
   • Install Nginx
2. Pull code and install
   • git pull origin main
   • npm install
   • npm run build
3. Create production env file
   • cp .env.example .env.production
   • Fill real values in .env.production
4. Set up systemd
   • Copy deploy/systemd/landing-page.service to /etc/systemd/system/
   • Update WorkingDirectory, EnvironmentFile, User, and Node path if needed
   • Run:
     • sudo systemctl daemon-reload
     • sudo systemctl enable landing-page
     • sudo systemctl start landing-page
5. Set up Nginx
   • Copy deploy/nginx/landing-page.conf to /etc/nginx/sites-available/landing-page
   • Replace domain and upstream port if needed
   • Enable config + reload nginx
6. Set up cron for email sequence
   • Use deploy/cron/email-sequence-cron.sh
   • Example crontab (daily 09:00 UTC):
     • 0 9 * * * CRON_SECRET=... BASE_URL=https://your-domain.com /var/www/landing-page/deploy/cron/email-sequence-cron.sh

SSH into the server, then:

bash /var/www/landing-page/scripts/vps-deploy.sh

Or manually: git pull origin main, npm install, npm run build, sudo systemctl restart landing-page.

Verify: open https://your-domain.com/api/store-info — should include "buildId":"2026-05-29-main". Homepage nav should show Giới thiệu Học viên.

If the public site still shows the old hero (“Nhận Bằng Cao Học”), the VPS is not running this repo’s latest code (wrong folder, old node process, or pull was run on your PC instead of the server).

• Never commit .env, .env.*, or resend_config.txt
• Rotate any previously exposed keys immediately
• Keep secrets only in server env / secret manager
