Развертывание Express сервера на nginx?

var express = require('express');
var app = express();
var path = require("path")

app.use(["/assets", "/user/assets", "/user/message/assets"], express.static(path.join(__dirname, "/assets")))



app.get('*', function (req, res) {
  res.sendFile(path.join(__dirname, '/index.html'));
});

app.listen(3000, () => {
  console.log("hi")
});

server {
        listen 80 default_server;
        root /var/www/nodejs;
        index index.html;
        error_page 400 401 402 403 404 500 501 502 503 /error;
        server_name 206.189.62.203;

        location / {
                proxy_pass http://localhost:3000;
                proxy_set_header Host #host;
        }

        location ^~ /nginx {
                root /var/www;

        }

}
