Step 4 — Create the nginx site file

Create a site file. Replace notes.example.com with your domain.

sudo nano /etc/nginx/sites-available/ai-notes-xyz

Paste this:

server {
    listen 80;
    server_name notes.example.com;

    client_max_body_size 16m;

    location / {
        proxy_pass http://127.0.0.1:2000;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

This sends / and /api to the app on port 2000.
